RSGB GB2RS News Bulletin for 9th June 2024

GB2RS News Sunday the 9th of June 2024  The news headlines: TX Factor is marking its tenth anniversary by launching its 30th episode Changes to the four-year planning rule in England Bath Based Distance Learning’s next Full licence course is starting soon TX Factor is marking its tenth anniversary by launching its 30th episode. It looks at how radio technology has advanced since Marconi conducted some of his early transmissions. The episode includes the first of a two-part feature on operating via the QO-100 geostationary satellite with a look at the hardware and software needed to achieve your first QSO at home or out mobile. Bob, G0FGX reviews the FTM-500D which is the latest mobile transceiver from Yaesu and demonstrates the many advanced features of this versatile FM and digital rig. There is a visit to Sidmouth Amateur Radio Society which secured a derelict former sports social club from the local council and turned it into a community hub and the club’s new QTH. Watch this interesting episode and don’t miss out on the TX Factor free-to-enter draw with a chance to win three RSGB publications. You can see this and previous episodes on txfactor.co.uk The four-year planning rule has offered a degree of protection for antennas and masts that have been erected without planning permission. Under this rule any installations which had been installed and unchanged for four years or more were protected against planning enforcement action. However, as of the 25th of April 2024, this rule ceased to exist in its current form in England under changes introduced under the Levelling-up and Regeneration Act 2023. The rule has been replaced by a more stringent ten-year period for the exemption from enforcement for residential dwellings. This change does not affect Wales, Scotland and Northern Ireland where the four-year rule will continue to apply. Any installation that was substantially completed before the introduction of the Act will still be subject to the four-year rule meaning, for most radio amateurs, the ten-year rule will not apply until the 24th of April 2028. For more information on planning matters visit rsgb.org/planning Bath Based Distance Learning’s next Full licence course runs from August to December, with exams in January. There is no charge for the training, but applicants must work through some pre-course material and complete a quiz to be eligible for a place. To request full details, and an application form, please email Bath Based Distance Learning’s Team Leader, Steve, G0FUW via [email protected] A reminder that the RSGB is asking radio amateurs to share their ideas on the theme of ‘change and adapt’, as part of plans for British Science Week 2025. The event is run by the British Science Association and celebrates science, technology, engineering and maths. The 2025 theme offers a huge range of opportunities for creativity and discovery. Ideas could cover any area from construction to propagation, from making QSOs under supervision to space and satellites. This is a chance to show young people in schools, or anyone in your local community, just how interesting and enjoyable amateur radio can be. Please send ideas to the RSGB British Science Week Coordinator Ian Neal, M0KEO at [email protected] To find out more about the previous year’s activities, or next year’s theme, you can visit rsgb.org/bsw Don’t forget that you have the opportunity to get even more out of your RSGB membership.

More information is available from the Worked All Britain website. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 6th of June 2024 It seems that we haven’t had a repeat performance of the auroral conditions caused by active sunspot region 3697. For Aurora watchers, that could be a disappointment, but for HF lovers it means the bands have been quite settled. The Kp index has been at 3 and below, while the solar flux index has been consistently above 175 all week. As a result, HF conditions have been quite good with maximum usable frequencies over a 3,000km path being regularly over 21MHz and often 24MHz. It is always a good idea to operate on the highest HF band that is open as absorption decreases the higher you go. Meanwhile, Sporadic-E propagation brought interest to the 10m band with stations from all over Europe being workable for long periods, but more of that in the VHF report. On the 5th of June, a filament located in the northeast quadrant erupted. The event flung a coronal mass ejection into space that doesn’t appear to be Earth-directed. But this shows that we are still in the danger zone for major solar events, and anything could happen. Next week, NOAA predicts that the solar flux index will remain around 175, but we expect some geomagnetic disruption today, the 9th of June, with a predicted Kp index of 4. Otherwise, solar conditions are predicted to be calm next week. So, if these conditions continue, this is a good time to make the most of the HF bands. And now the VHF and up propagation news from G3YLA and G4BAO The weather pattern for the coming week is dominated by low pressure, which means there is unlikely to be any significant Tropo to speak of.  There will probably be several opportunities for those on the GHz bands to search for rain scatter. However, these events look to be moving showers or rain bands, which means that you’ll need to be pretty agile with the rotator to keep on the scattering target. With the solar conditions continuing to keep the pot simmering it's not impossible that the Kp index could rise high enough to promote an aurora, but it's a low probability. The early part of June is well regarded for minor meteor events and should be worth a look for those using meteor scatter modes. There were several Sporadic-E openings early in the week that finish today, the 9th. Sporadic-E was reported up to the 2m band on a few occasions. Last Sunday, the 2nd, lasted up to three hours on the path from Eastern England down to the Italian peninsula. Events initially get picked up on the 10m band and then move up through the VHF bands of 6m, 4m and finally 2m as the Sporadic-E propagation strengthens. In this peak of the Sporadic-E season, the openings on the lower bands, such as 10 and 6m, can be present for much of the day and certainly quite late into the evening. Follow the weather patterns on the daily Sporadic-E blog on propquest.co.uk and you should be able to point in the right direction for an opening. Multi-hop paths to the Far East or the Americas require a good antenna like a beam, but single-hop European Sporadic-E propagation can be very strong, and any antenna will do the job. Moon declination is at its maximum this weekend for the DUBUS 10 and 24GHz EME contest, but EME path loss is rising. 144MHz sky noise is low all week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 2nd June 2024

GB2RS News Sunday the 2nd of June 2024  The news headlines: Nominations for IARU President and Vice President have been ratified The next RSGB Tonight@8 webinar is coming up RSGB National Radio Centre to operate D-Day anniversary special event stations   IARU member societies have ratified the nomination of Tim Ellam, VE6SH/G4HUA and Thomas Wrede, DF2OO as IARU President and Vice President, respectively, for a five-year term which began on the 9th of May 2024. On starting his 4th term as President, Tim Ellam thanked member societies for their support, congratulated Thomas Wrede on his election as Vice President, and also offered a special and heartfelt thank you to Ole Garpestad, LA2RR who retired as IARU Vice President. You can read more on this story via the IARU website at tinyurl.com/IARU2024 The RSGB Tonight@8 webinar this Monday, the 3rd of June, examines how amateur radio can be accessible and enjoyable even if you have sight, hearing or mobility difficulties. Three radio amateurs will explain how they have adapted their equipment, written software or used extra support from the RSGB or other radio amateurs, to enable them to enjoy all that amateur radio has to offer. There will also be input from Sight Matters, an Isle of Man charity helping to assist over 700 visually impaired members. The charity has recently discovered how much amateur radio can offer people with visual impairments and it has formed the Sight Matters Amateur Radio Club. This aims to encourage new people into the hobby and to help assist existing licence holders back onto the air. Whether this webinar is relevant to you, a friend or colleague, or you’re in a club that is wondering how to support all radio amateurs to enjoy the hobby, make a note of the date and be inspired! You can watch and ask questions live on the RSGB special BATC channel or YouTube channel at youtube.com/theRSGB The RSGB’s National Radio Centre will be operating a special event callsign GB2DAY to commemorate the 80th anniversary of the D-Day landings during World War Two. The station will be active between the 6th  and 9th of June. In addition, volunteers will be hosting the special demonstration station GB1SOE on Saturday the 15th of June. Don’t forget that RSGB members can gain free entry to Bletchley Park and the RSGB’s National Radio Centre by downloading a voucher from the RSGB website: rsgb.org/bpvoucher The RSGB Board recently spent an afternoon visiting RSGB Headquarters, meeting staff and gaining a more detailed understanding of the work of this professional team. Later that day, the Board received training from members of the senior team about their specialist areas. During the Board meeting the following day, the Board decided to continue with its chosen four strategic priorities until the 2025 AGM. These priorities are the growth of amateur radio; membership of the RSGB; spectrum and licensing; and ensuring the continued financial stability of the Society. To make further progress with the outcomes of the recent growth workshop, the Board allocated a member of its team to champion each of the seven workstreams. Each workstream champion will now create a volunteer team, prioritise work tasks, set measurable objectives, define what success looks like, list deliverables and establish reporting mechanisms and frequency. More details will be shared about these over the coming months. Do you have some spare time to support fellow radio amateurs? Are you passionate about the future of amateur radio? Do you like a challenge? The RSGB currently has volunteer vacancies for Regional Representatives in Region 7 South Wales, and Region 12 England East and East Anglia. Could you fill one of those roles? To learn more about being a Regional Representative see the RSGB website or contact the Regional Team Forum Chair, Keith Bird, G4JED via [email protected] Next week is the 40th anniversary of Volunteers’ Week in the UK.

But is that all about to change? Active region 3664 has returned. It is now named 3697 and has already emitted an X1.4-class solar flare. You may recall that it was AR 3664 that caused the aurora that was visible all over the UK around the 10th and 11th of May. As Solarham.com says, “The chances for an Earth-directed eruption will increase with each passing day as the active sunspot region turns into a better geoeffective position.” Scientists now believe that the coronal mass ejection associated with the long-duration X1.4-class flare on Wednesday the 29th may pass close enough to Earth to generate moderate G2 geomagnetic storming beginning on the 31st of May – just in time for this weekend’s National Field Day! Otherwise, HF propagation has generally been good with decent F2-layer openings up to 21 and even 24MHz at times. The 17 and 15m bands look to provide the best DX, with paths to the east in the morning, and to the west during late afternoon and early evening. The 10m band is subject to Sporadic-E openings, with F2-layer openings mainly restricted to paths to South Africa and South America. Next week, NOAA predicts that the solar flux index will be in the 165 to 200 range, with quiet geomagnetic conditions. However, that is perhaps a little optimistic as active region 3697, or perhaps 3691, could easily throw a spanner in the works, with a flare and associated CME potentially sending the Kp index skywards. So, as always, keep an eye on the current state of the Sun at solarham.com, and work the bands while they are open! And now the VHF and up propagation news from G3YLA and G4BAO The close of the current week offers a temporary return of high pressure for this weekend. This should be good for some Tropo conditions for western parts of the UK. The weather turns a bit more unsettled going through the coming week, especially over northern Britain, but also occasionally in the south. Rain at this time of the year can often be heavy and thundery with good prospects for GHz bands rain scatter, but this may have to wait for the end of next week when a low moves north from France towards the southern UK. The early part of June is a time of several minor meteor showers. These should offer scope for meteor scatter operators as well as provide some fuel for Sporadic-E propagation which rocket measurements show consists of long-lived meteor ions. Sporadic-E propagation is often associated with the position of jet streams in the upper troposphere due to the turbulence that these fast-flowing currents of air generate. In the coming week, the jet stream pattern becomes much weaker, although still with a few options. Daily blogs are available at Propquest.co.uk  for those who are interested. Don’t ignore the prospects for multi-hop transatlantic paths to the United States and particularly the Caribbean, which are usually well supported in the early part of the season before the upper winds over the Caribbean change over to high-summer slacker flow.  Equally, multi-hop Sporadic-E paths to the Far East are worth checking in the early morning following the effects of the now displaced northerly meandering jet stream flow across northern Russia. Moon declination went positive again on Saturday the 1st of June, so the coming week will see lengthening Moon windows. EME path loss is falling, reaching a minimum at perigee today, Sunday the 2nd of June. 144MHz sky noise is low apart from Thursday when the Sun and Moon are close in the sky. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 26th May 2024

GB2RS News Sunday the 26th of May 2024   The news headlines: The RSGB’s Exams and Syllabus Review Group is seeking volunteers RSGB representatives had a successful time at Dayton Hamvention The RSGB Discovery scheme has just been relaunched in a new format The Exams and Syllabus Review Group – or ESRG as it is often known – is looking for new members to move the group forward. Its current task is to approve a new Direct to Full syllabus and to write and approve new questions for the new exams in September due to licence changes. The group meets online every Tuesday between 3 pm and 4.30 pm, with members of the Exam Standards Committee, but meeting times can be changed to accommodate everyone. ESRG volunteers need to be Full licence holders, members of the RSGB and be able to give a few hours a week. This is your chance to shape the future as we move to Syllabus 2.0 in 2025. To volunteer or find out more, contact the ESRG Chair Andrew Lenton via [email protected] Members of the RSGB Team, including RSGB General Manager, Steve Thomas M1ACB and the RSGB President, John McCullagh GI4BWM had a successful time at the Dayton Hamvention last weekend. The event was a brilliant opportunity to engage with radio amateurs from around the world and resulted in 132 people joining or rejoining the RSGB. There were also several podcasters, YouTubers and local news outlets in attendance. This included WHIO, which is a local US news channel, who interviewed RSGB President, John McCullagh GI4BWM. This was shared on local TV news, radio, as well as online.

Now called the Discovery Logbook, there are fewer requirements, an easy-to-follow programme and exciting links with external organisations such as Parks on the Air and Worked All Britain. There are also some great RSGB Awards to work towards if you’d like to include those in your programme of activities. The RSGB hopes that these links will enable radio amateurs to discover new ways of enjoying their hobby with the guidance and support of experts in those fields. There are three difficulty levels and the first of these, called Explorer, has just been launched. To see the programme activities, find out how to get involved or talk to the Society about linking your organisation with the Discovery Logbook, go to the RSGB website at rsgb.org/discovery British Science Week is an annual event run by the British Science Association celebrating science, technology, engineering and maths. The event, which is taking place between the 7th and 16th of March 2025, will have the theme ‘change and adapt’, which lends itself perfectly to amateur radio in the 21st century. As part of its commitment to encourage new radio amateurs into the hobby, the RSGB will again be providing resources and activities to inspire people of all ages to get involved. The RSGB is now collecting ideas for activities for primary and secondary schools, or for use with the wider community. The 2025 theme offers a huge range of opportunities for creativity and discovery. Ideas could cover any area of the hobby, from construction to propagation, from making QSOs under supervision, to space and satellites. Whatever the idea, the Society would love to hear from you. Please send ideas to the RSGB British Science Week Coordinator Ian Neal, M0KEO at [email protected].

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 22nd of May 2024 After the extremely unsettled HF conditions on the 10th and 11th of May, it was gratifying to see things returning to normal last week. The Kp index has returned to being in the range of 1 to 4 and, with a solar flux index still in the 190s, we have seen some good propagation around the world. But make no mistake – it probably won’t last! Active region 3664, the source of so much mayhem a couple of weeks ago, will soon return from its trip around the Sun. It has probably been the source of a major flare while on the Sun’s far side and there is a good chance we may get a repeat performance of last month. Meanwhile, make hay while the Sun shines! NOAA predicts that the solar flux index will increase above 200 next week, but unsettled geomagnetic conditions are forecast for tomorrow, the 27th of May, and at the end of the month and into early June. Daytime critical frequencies have been between 8 and 9.3MHz, making 40m a good band for inter-G QSOs. These have also meant that the maximum usable frequency over a 3,000km path has often exceeded 24 to 27MHz, making 12m a viable band for DX. Note that this is a little patchy, so if you don’t hear anything on 24MHz just wait a while or check later. Nighttime critical frequencies are usually around 6 to 7MHz, meaning 20m is generally open all night with occasional openings on 17m. We are now well into the Sporadic-E season so there should be lots of short-skip into Europe on the 12 and 10m bands to play with. And now the VHF and up propagation news from G3YLA and G4BAO The end of the current week, in the lead-up to the bank holiday weekend, shows a low and its thundery rain moving north and leaving behind a slack area of pressure with a weak trend towards building a ridge over the country. The bulk of next week is showing up with a slack westerly pattern and weak fronts brushing past. From midweek, and towards next weekend, the frontal systems will be more active with longer periods of heavier rain possible. The end result for most VHF and up operators is that there may be some occasional Tropo events, especially overnight during the slacker period with the weak ridge over the country by the start of the weekend. A more likely option will again be rain scatter which will produce better scattering from the larger raindrops now the summer season is upon us, and thundery developments are more common. Check the many online weather radars for your tracking beam headings. Meteor scatter will also be worth considering since we are approaching the period when many lesser showers appear to pep up the background meteor count. This will be useful for meteor scatter operators and serve the Sporadic-E folk well. The solar activity continues to deliver random events which take the Kp index to high values. Remember that a Kp index greater than 5 indicates the chance of aurora propagation. The primary mode at this time of the year is Sporadic-E. The late May and early June period is often regarded as a peak time for monitoring your favourite VHF beacons. As many will know, the 10m band is a useful starting point for identifying the beginning of an opening, and then you should check the higher bands in turn as the event strengthens. This is often indicated by the skip distance shortening on the 10m band. The other basic operating tip is to use the daily blog on the Propquest.co.uk website for commentary on the effectiveness of the various upper air patterns such as jet streams, which can influence the location where Sporadic-E propagation occurs. There are no major meteor showers this week so, in between the Sporadic-E, look around dawn for the best random meteor prospects. Saturday the 22nd sees the lowest Moon declination of the month so next week will see some lengthening Moon windows. EME path loss is falling, but we are still over a week from perigee, its closest point to Earth. 144MHz sky noise starts the week high, as it reached over 2500 Kelvin on Saturday the 25th. It is low for the rest of the week. And that’s all from the propagation team this week.

On Sunday the 26th, the UK Microwave Group High Band Contest runs from 0600 to 1800UTC. Using All modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 16th of May 2024 After last weekend’s auroral spectacular, it was nice to see the Sun calm down a little and the bands get back to normal. But that didn’t last long. To recap, on Friday the 10th of May the Kp index shot up to 9, due to the effects of a number of coronal mass ejections, while the HF bands closed down in the subsequent geomagnetic storm. While there was visible aurora across the UK and Europe, HF propagation suffered and didn’t start to recover until the late afternoon on Saturday the 11th. The main culprit, active region 3664, has now rotated out of view, but that doesn’t mean we are out of the woods just yet. Solar flares can cause short-term disruption to HF propagation due to their X-rays penetrating deep into the D-region and causing signals to be absorbed. Subsequent coronal mass ejections can cause longer-term degradation of the F2 layer with reduced maximum usable frequencies, noisy bands and auroral conditions.  At the time of writing, the Kp index stood at 6 again so it looks like unsettled geomagnetic conditions are continuing with a moderate G2 geomagnetic storm in progress. Low to moderate activity is now expected, with a slight chance of further strong-class flares. The regions currently on the visible disc are smaller and simpler, with isolated M-flares possible from these. However, a new active region, now rotating into view, has already emitted an X-class solar flare. Next week, the United States Air Force predicts that the solar flux index may remain in the 160 to 180 range. HF conditions remain a lottery as they can be badly affected by solar flares and coronal mass ejections. It is best to keep an eye on solarham.com for updates, and also propquest.co.uk for near real-time reports of the critical and maximum usable frequencies. And now the VHF and up propagation news from G3YLA and G4BAO The weather remains on the unsettled side of things with areas of rain and some thunderstorms over the country, especially the south as we end this week. As this report is being read out, high pressure is becoming established over northern and western Britain. This may eventually take a tenuous hold over the rest of the country during the second half of the coming week and into next weekend, the 25th and 26th. This high pressure, although fairly weak, may help with some Tropo for those in northern Britain in the 144MHz May Contest and the Backpackers Contest this weekend, ending on the 19th. It may also be helpful to those taking part in the 1.3GHz UK Activity Contest on the 21st. However, the conditions may not be of much use in the south as another low arrives from the continent. Overall, rain scatter on the GHz bands will probably be worth exploring in the rainy areas again, since some of the showers may be heavy and thundery. The prospects for Aurora are still worth keeping in mind despite the recent stunning event. Minor non-visible events can still provide a reasonable radio aurora to explore. The Sporadic-E season continues to develop. And with such unsettled weather, there are plentiful jet streams to act as source regions for turbulence, which can propagate up to the E region where they can generate Sporadic-E. We are currently at the tail end of the Eta Aquariids meteor shower. A few meteors from this shower will continue to appear, but no major shower is expected this week. The lowest Moon declination occurs this coming Friday. With the Moon being full on the 23rd, a clear sky should reveal an impressive ‘Flower Moon’. For EME, path loss will still be relatively high, although the Moon is starting to move back towards its closest point to Earth, or perigee. 144MHz sky noise starts the week low but rises to high on Saturday the 25th. And that’s all from the propagation team this week.

On Thursday the 16th, the 70MHz UK Activity Contest runs from 1900 to 2130UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator. The 144MHz May Contest starts at 1400UTC on Saturday the 18th and ends at 1400UTC on Sunday the 19th of May. Using all modes on the 2m band, the exchange is signal report, serial number and locator. UK stations also send their postcode. On Sunday the 19th of May, the 1st 144MHz Backpackers Contest runs from 1100 to 1500UTC. Using all modes on the 2m band, the exchange is signal report, serial number and locator. UK stations also send their postcode.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 9th of May 2024 Disrupted solar conditions continued this week with X-class solar flares aplenty. Four X-class events on the 8th and 9th of May prompted coronal mass ejections, which could join together to impact the Earth this weekend. We can expect a strong G3 event with the Kp index rising to 6 and the potential for visible aurora in the UK. It’s hard to be positive about this as HF conditions this weekend, ending today the 12th, are likely to be very disrupted with reduced MUFs and noisy bands. But do look out for auroral signals, perhaps on the 10m band, and above, and a potential HF band enhancement just as the plasma cloud hits. The solar flux index hit 227 on Thursday the 9th, which is one of the highest we have had in this cycle. But don’t get carried away as it is forecast to decline. Meanwhile, conditions have been typical for this time of year, with reduced F-layer propagation on the 10m band, offset by the start of the Sporadic-E season. The lower HF bands are staying open later in the evening, and may even increase to all night on the 20m band, as we head towards June and July. Next week, NOAA predicts that the solar flux index will drop below 200, but remain at or above 175 all week. After this weekend’s chaotic geomagnetic conditions, we can expect the Kp index to fall to 2, but increase again on the 13th, to perhaps 4. In the meantime, solar maximum is still predicted to be later this year, although geomagnetic disturbances are likely to increase on the downward part of the cycle. So, buckle up for a rough ride! And now the VHF and up propagation news from G3YLA and G4BAO We end the current week with high pressure over the country and some occasional Tropo paths, especially over surrounding waters. The high will decline from the west as we progress through this weekend. At the time of reading on Sunday, the transition will be all but complete and low pressure will remain in control for much of the coming week. This means periods of rain, heavy showers or thunderstorms and quite windy weather at times. In terms of propagation, a shift to rain scatter is a good choice for those equipped for the GHz bands for the week ahead. Recent solar activity continues to offer chances of auroras so remember to monitor the Kp index and check for fluttery signals on the HF bands and raspy signals on VHF. The many clusters and band reports should be a good tool for these conditions. Lastly, the Sporadic-E season is having a few starting twitches. Earlier in the evening of Wednesday the 8th there was a short opening of about an hour to Scandinavia on 6m CW from a patch in the middle of the North Sea. The positions of the jet streams may not entirely suit further openings in the shorter term but, as the low-pressure moves in next week, things could improve for Sporadic-E paths to Iberia and central Mediterranean. With the Eta Aquariids peak now past, the next big meteor shower isn’t until July with the Delta Aquariids. But before the Delta Aquariids, we can look forward to the Arietiids in late May. However, the Eta Aquariids will continue to produce the odd ping or burst. Last week there was plenty of evidence of meteors continuing to burn up after the peak. There may still be the odd one during the coming week together with the usual background sporadic meteor returns. As the Moon starts to decline this week, the distance between the Moon and Earth is also beginning to increase and with it the path loss increases to a maximum on Friday the 17th and Saturday the 18th. However, sky noise will remain low all week. The Moon is favourably placed for daytime operation this week. And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 2nd of May 2024 What a strange week we had. With the solar flux index in the 167 range, falling to 130, conditions should have been reasonable. But the Kp index hit 4, and even 5.33, on the evening of Friday the 26th of April, which meant propagation on Saturday the 27th was truly dire. Stations taking part in International Marconi Day on the 27th found the 40m band only open to long skip in the morning. This was due to the critical frequency being below 5MHz. The predicted MUF over a 3,000km path fluctuated between 15MHz and 19MHz for the whole day, which meant only 14MHz was open reliably. As a result, QSOs were hard to come by and many stations reported that it was slow going with virtually no signals from outside of Europe. So what happened? Well, it was a combination of factors. The increased Kp index, due to a fast solar wind, took its toll. And we are now moving to a summer ionosphere, where chemical changes make it harder to ionise. This will mean we should see MUFs dropping as the season progresses, at least during the day. Nighttime MUFs will be higher than in winter. So it may be that the glory days of 28MHz F2-layer propagation are on hold until Autumn, with only short-skip Sporadic-E on the 10m band to keep us entertained. F2-layer propagation is still available on the higher HF bands, but it may be patchy. International Marconi Day station GB0CMS in Caister, Norfolk, reported that its 20m signals were picked up by a reverse beacon network skimmer in Utah, despite not working anyone outside of Europe. Meanwhile, on the morning of the 2nd, Laurie, G3UML was quite surprised to work YJ0CA on Vanuatu on the 15m band using SSB. He also worked 3D2CCC on Conway Reef on the 20m band using CW, and JD1BMH in Japan on the 15m band, also using CW. Next week NOAA predicts the solar flux index will be in the 125 range, rising to 175 as the week progresses. Geomagnetic conditions are dependent on coronal mass ejections. We have had eight M-class solar flares in the past three days, and a Kp index of 5 on Thursday the 2nd, which doesn’t bode well for next week. So, keep an eye on solarham.com for current conditions and look for the best HF propagation if the Kp index is low for a day or two. And now the VHF and up propagation news from G3YLA and G4BAO The weather pattern remains very unsettled for the whole period with areas of low pressure edging north across the UK from the continent. There will be a risk of thundery weather at times with locally heavy rainfall, which will be good for rain scatter on the Gigahertz bands. Tropo looks to be hard to find as we end the current week dominated by low-pressure systems, but there are signs of high pressure returning after mid-week, but only temporarily. This could produce some Tropo paths, especially across surrounding waters such as the Irish Sea, English Channel and North Sea. The nominal summer season of Sporadic-E propagation is upon us and, from May to early September, daily blogs will be provided on the Propquest.co.uk website highlighting the possible Sporadic-E links to the position of the jet streams shown on the upper air charts. It’s well worthwhile getting into the habit of regularly checking the DX clusters and activity maps, since the early season is usually characterised by a complex jet stream pattern with multiple potential locations for Sporadic-E propagation.  Timewise, it eventually settles into a more traditional behaviour with activity often in two phases, one in the morning and the second in late afternoon, early evening. As you listen to this report, the Eta Aquariids meteor shower should be peaking. Unfortunately, the best viewing for the shower, which is part of the debris from Halley’s comet, will be in the southern hemisphere. Nevertheless, this is expected to be one of the best showers this century. For those viewing the shower, a waning Moon means that light levels should be low, making for ideal visual sighting. For EME, the Moon will be waning all week with the new Moon around the 8th of May. The Moon will be rising in the sky throughout the week, with zero declination on the 5th of May and peaking at its highest in the sky on Saturday the 11th of May. The lowest additional path loss occurs today and tomorrow, the 5th and 6th, but high Sun noise, with the Moon close to the Sun at new Moon, occurs shortly afterwards. Later in the week, as the Sun 'leaves' the Moon behind, noise levels, at least on the higher bands will fall to around normal. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 28th April 2024

GB2RS News Sunday the 28th of April 2024   The news headlines: New mock papers for amateur radio licence exams have been published A revised amateur radio examination syllabus has been released The RSGB has released the video review of 2023 by its President John McCullagh, GI4BWM The RSGB Exam Syllabus Review Group has published a new set of mock papers covering each of the amateur radio licence exams, from Foundation through to Direct to Full. These papers are in addition to those already available. They are each marked as ‘mock exam paper 3’ and you can find them on the RSGB website at rsgb.org/mock-exams  The new amateur radio licence has now been in effect for a few weeks. Changes to the licence conditions have made it necessary to revise the examination syllabus. The RSGB is pleased to release version 1.6 of the syllabus which includes these revisions. Compared to version 1.5 in current use, the only section that has seen major changes is Section 1 – “Licensing and station identification”. In Section 7 – “Operating practices and procedures” – there were some minor changes, for example regarding suffixes. Exams will start using version 1.6 of the syllabus on the 1st of September 2024. The Society has released the video review of 2023 by RSGB President John McCullagh, GI4BWM. Filmed at the Ofcom Spectrum Management Centre near Baldock in Hertfordshire, the video covers a wide range of very positive activities, events and achievements. The President also talks about the RSGB’s strategic priorities, gaining publicity in the mainstream media, and the important work done by the Society on behalf of all radio amateurs to protect the spectrum. One example is the WRC Conference, where the RSGB Microwave Manager Barry Lewis, G4SJH, led the IARU team responsible for defending amateur use of the 23cm band. You can watch the video on the RSGB YouTube channel at youtube.com/theRSGB At the April Regional Forum meeting, Regional Representative 10, Keith Bird, G4JED was elected as Chair, and Regional Representative 3, Martyn Bell, M0TEB was elected as Secretary.

Using CW, RTTY and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. Italian stations also send their province. On Sunday the 5th, the UK Microwave Group Low Band Contest runs from 0800 to 1400UTC. Using all modes on 1.3 to 3.4GHz frequencies, the exchange is signal report, serial number and locator. Also on Sunday the 5th, the UK Microwave Group Millimetre Wave Contest runs from 0900 to 1700UTC. Using all modes on 24, 47 and 76GHz frequencies, the exchange is signal report, serial number and locator. On Sunday the 5th, the Worked All Britain 7MHz Phone Contest runs from 1000 to 1400UTC. Using SSB on the 40m band, the exchange is signal report, serial number and Worked All Britain Square. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of April 2024 We had another week with plenty of sunspots, and HF conditions were quite good in the second half. Earlier, the Kp index reached 3 and 4, which didn’t help maximum useable frequencies, or MUFs for short. For example, on Sunday the 21st, the Kp index rose to 4 and the MUF over a 3,000km path remained stubbornly below 21MHz until later in the morning. This could have been due to a coronal hole on the Sun’s equator, which added to the solar wind. By Wednesday, conditions were nearly back to normal, with a Kp index below 2 and an MUF of more than 24MHz. By Thursday the improvement had continued, giving us an MUF of more than 28MHz by 0900UTC. There have been many reports of 10m band DX being worked, including Sebastien, FK4AX and Pat, FK8HA in New Caledonia in the Pacific on SSB. Sebastien has just got his licence and is keen to work DX from the UK. This shows that it is worth keeping an eye on the CW and SSB portions of the 10m band, which can often throw up surprises. Next week, NOAA predicts that the solar flux index will decline to around 160. The Kp index is predicted to be around 2 to 3, but that may be wishful thinking. With 16 active regions visible on the Sun’s surface on Thursday, anything could happen. Only minor C- and M-class flares have occurred recently but, as we always say, it wouldn’t take much for those to turn into X-class events. So, make the most of quiet geomagnetic conditions when we have them as, by the time you read or hear this, we could once again have very unsettled conditions indeed. And now the VHF and up propagation news from G3YLA and G4BAO The cold, unsettled weather will ease its grip over the last few days of this week, ending the 28th of April, but only because the whole area of low pressure is moving across the country this weekend. Low pressure remains close by for much of the following week and only a hesitant return of high pressure west of Ireland will improve things for western Britain at the end of the week. The result is a chance of Tropo for western Britain next week, but it will probably be of limited quality since it is likely to form in cold, dry air across any temperature inversion.  The remaining option in such weather patterns is primarily rain scatter for those on the GHz bands. The many online weather radar displays can be used to highlight the areas of heaviest rain. We are past the peak of the Lyrids meteor shower, but the Eta-Aquarids, with a Zenithal Hourly Rate of 50, peaks next Sunday the 5th around 2100UTC. Until then, rely upon random activity which tends to be better around dawn. The Sun has been more active again recently, so monitor the clusters and Kp index for signs of geomagnetic activity and the chance of an aurora if the Kp index exceeds 5. Sporadic-E tends to produce a few early examples in May ahead of its June peak. Check the DX clusters during the late afternoon or early evening as openings can be very brief early in the season. Start on the 10m band and, if short skip within Europe is present, move up to the 6m band. Digital modes are more sensitive so check FT8 reports to give clues as to where the chances are greatest. For EME operators, the Moon is at minimum declination today, Sunday the 28th, meaning we’ll have short Moon windows to start the coming week. Path losses are falling but perigee, when the Moon is at its closest point, is still over a week away. 144MHz sky noise is high this weekend, ending the 28th of April, but falls too low by the end of the coming week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 21st April 2024

GB2RS News Sunday the 21st of April 2024 The news headlines: Dr Stewart Bryant, G3YSX to continue as RSGB Board Chair The RSGB has vacancies for Regional Representatives The Radio Communications Foundation is recruiting new Trustees   The RSGB Board has met for the first time since the Society’s AGM where three Directors were endorsed to serve as Nominated Directors on the Board and one was confirmed as elected unopposed. The new Board has chosen Dr Stewart Bryant, G3YSX to continue in the role of RSGB Board Chair until the 2025 AGM. You can find details of all RSGB Board Directors on the Society’s website and the Board Liaison roles will be confirmed and added to the page in the coming weeks. Go to rsgb.org/board for more information. At its recent AGM, the RSGB was delighted to confirm the unopposed election of five Regional Representatives. However, there are still vacancies for Regional Representatives in Region 11, which covers England South-West and the Channel Islands, and also Region 12 which is England East and East Anglia. These vacancies will be filled by co-option until the 2025 AGM. If you live in one of these areas and are passionate about amateur radio, keen to support local radio amateurs and clubs, and have the skills to lead a volunteer team of District Representatives in the region, this could be a role for you! To find out more, please contact Tony Miles, MM0TMZ who is the Board Liaison for the Regional Team via [email protected] The Radio Communications Foundation is a small charity dedicated to encouraging people to take up radio as a hobby or, in the case of youngsters, considering an RF-based career. The RCF is proud to sponsor Arkwright Scholars, work with the RSGB and Bletchley Park to deliver radio-building workshops and make grants for various projects around the UK. Further information is available via the RCF website at commsfoundation.org  The RCF is now looking to recruit a couple of new Trustees to help it deliver its aims. Applicants should have an interest in radio communications and be prepared to be involved in decisions over grant-making, delivering RCF projects and attracting charity funding. The RCF would particularly like to hear from anyone with links to secondary education in the UK. Expressions of interest and applications should be sent to [email protected] preferably by the end of June. Following the introduction in February of the new Ofcom amateur radio licence conditions, the RSGB has continued to provide information and support to radio amateurs to help them make the most of the changes. This has included updates, club talks and a section of the AGM event focused on those licence changes. Go to the RSGB YouTube channel, choose the AGM recording from the ‘live’ tab and then watch two sections. Firstly, the main Board Q&A begins just after one hour and eighteen minutes into the event and includes some licensing questions from members. Secondly, a section from just before two hours and thirty-three minutes focused entirely on the new licence conditions and included three videos and a full live Q&A with four senior RSGB representatives. The Society has also published a wealth of information on its website which you can find at rsgb.org/licence-review Nigel Limb, M7FFU, had a motorbike accident in 2015 that left him with permanent brain damage and partially blind in both eyes, but this didn’t stop him from pursuing his childhood dream of obtaining his amateur radio licence. In December 2023 he passed the Foundation Licence exam. In the early 1970s Sue Jacob, GW7YLS was a shortwave listener and interested in amateur radio, but it wasn’t until she retired and discovered that the exams no longer contained Morse code, that she decided to get more involved. Within 18 months she had passed all three licence levels. One of the great things about amateur radio is that it is accessible to everyone. The RSGB is celebrating this by collecting stories of radio amateurs who have passed their Foundation licence, or progressed through the licence levels, and are now discovering new aspects of amateur radio to enjoy. If you’d like to read more about Nigel, Sue and others, go to rsgb.org/student-stories and, if you’d like to share your story with the Society, email [email protected] and the RSGB will use as many as possible. A new amateur radio Facebook group has been formed for those who like getting out and about in motorhomes, campervans, and caravans. The group welcomes all radio enthusiasts. To find out more, or to join the group, search for ‘UK Motorhome and Amateur Radio Group’ on Facebook. SOS Radio Week is an annual event that takes place throughout May to celebrate the work of the volunteers from the Royal National Lifeboat Institution, Independent Lifeboats and National Coastwatch Stations around the British Isles. Members of these organisations save many people between them who are in danger along and around the thousands of miles of coastline and further out to sea. This year is the 200th anniversary of the founding of the RNLI and SOS Radio Week is being co-branded SOS Radio Week 200 for those operators that are supporting the RNLI during the event. Participants can operate from home, a public location, or a lifeboat or Coastwatch station, with the appropriate authorisation from the station manager. A commemorative certificate will be available to all official stations that record their contacts on the website together with awards for the top individual and club, or group, stations on each band from 160m to 70cm. Registration for individual and group operators is available via sosradioweek.org.uk International Marconi Day will take place on Saturday the 27th of April. Once again, the Cornish Radio Amateur Club is organising and running the event. Lots of amateur radio stations will be operating from sites that Marconi operated from or had a personal connection with.

On Sunday the 28th, the British Amateur Radio Teledata Group Sprint 75 Contest runs from 1700 to 2100UTC. Using 75-baud RTTY on the 80 to 10m bands, where contests are permitted, the exchange is your serial number. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 18th of April 2024 Last week saw a welcome return of sunspots but, unfortunately, it also brought unsettled geomagnetic conditions. By Thursday the 18th the solar flux index was back above 200, hitting 217. Compare that to the previous week’s 131 and you can see that there is a lot more activity. But, with 12 active regions visible, it looks like we could be in for a bumpy ride over the next seven days. The Kp index hit five on the evening of Tuesday the 16th of April after the interplanetary magnetic field, or Bz, swung southwards, sparking visible aurora in the UK as far south as Dartmoor. This impacted the ionosphere, pushing MUFs over a 3,000km path down, with recovery not showing itself until 0930UTC on Wednesday the 17th. The 10m band is struggling to open at times, although you may find FT8 still passing weak signals. SSB operators might be better advised to look at the 12 and 15m bands which may provide richer pickings. Next week, NOAA predicts that the solar flux index may decline to be in the range of 170 at the beginning of the week, falling to between 135 and 140 at the end of the week. The risk of an M-class flare is currently at 75%, with an X-class event at 20%. Despite this, NOAA predicts the Kp index will be around 2 for all of next week. However, there is a chance that a flare and associated CME could scupper that completely. If we do get a coronal mass ejection, or CME for short, we can expect the Kp index to rise roughly 48 hours after the event, perhaps hitting 5 or more and possibly sparking visible aurora from the UK again. Overall then, it's good news on the sunspot front, but not so good for geomagnetic activity, which could see MUFs fall if any solar flares and CMEs come to fruition. And now the VHF and up propagation news from G3YLA and G4BAO The weather is likely to remain unsettled, despite temporary high pressure moving across the country this weekend. This may bring some Tropo, but it’s a cold air high and probably not the best for enhanced VHF conditions, except for localised overnight or early morning temporary lifts.  The rest of the time, there will continue to be an unsettled flavour to the weather so this leads to the possibility of rain scatter on the GHz bands, especially if we get heavy April showers. This first weekend coincides with the peak of the Lyrid meteor shower which peaks tonight, the 21st and 22nd, so it’s worth checking the usual meteor scatter frequencies. If you are not familiar with meteor rates and variations from day to day, then visit the excellent Radio Meteor Observing Bulletin at rmob.org which gives an hourly display from various locations around the world. You can find many other useful links to meteor scatter resources by searching for ‘meteor scatter’ at rsgb.org The Sun has woken up a little since last week, and a few auroral flutter signals on the LF bands suggest we shouldn’t give up yet for this spring. As usual, keep a watch for the Kp index going above 5. The late April period can provide some fleeting early season Sporadic-E events, especially for the 10 and 6m bands. A couple of weak 5MHz Sporadic-E critical frequencies were noted during the late afternoon on Wednesday the 17th on the Dourbes plot shown at propquest.co.uk For EME operators, Moon declination goes negative again today, the 21st, but path losses are falling as we passed apogee yesterday, the 20th. 144MHz sky noise is low but will rise to moderate by the end of next week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 14th April 2024

  GB2RS News Sunday the 14th of April 2024 The news headlines: RSGB member interviewed by the BBC about the total solar eclipse Ofcom releases video about changes to UK amateur radio licensing World Amateur Radio Day is coming up On Monday the 8th of April, a total solar eclipse gripped North America as radio amateurs worldwide looked on to see its effect on the ionosphere. This included RSGB Propagation Committee associate member Gwyn Griffiths, G3ZIL, who was interviewed by BBC news on the topic. The article, which was shared across the world, looked at some of the scientific experiments that took place during the eclipse. You can read the article by searching for “The 4-minute window into the Sun's secrets” on BBC news. The RSGB thanks all the WSPR users who responded to Gwyn’s call to action, got involved and shared their results on the RSGB social media channels.  Ofcom has released a video about changes to the UK amateur radio framework covering licensing and callsign changes. It also gives some insight into the forthcoming Phase 2 and Phase 3 of the changes for callsigns and special event stations. You can watch the video at tinyurl.com/ofcomvid World Amateur Radio Day is celebrated each year on the 18th of April. The theme for 2024 is “A Century of Connections: Celebrating 100 Years of Amateur Radio Innovation, Community and Advocacy.” The global event covers all of the IARU regions and runs from 0000UTC on Thursday the 18th of April to 0000UTC on Friday the 19th of April. All radio amateurs are invited to take to the airwaves to show their skills and capabilities to the public. You can read more about the event at tinyurl.com/iaruward During May, the RSGB’s Photo Friday feature on social media will highlight radio amateurs who are taking advantage of the new licence conditions. You could be an individual who is discovering different things to enjoy with the new power levels, or who is encouraging friends and family to get on the air under your supervision. You could be a club involved in special events and outreach to the public. In whatever way you’re making the most of the new licence conditions, the RSGB wants to hear from you! Send a photo and a short description to [email protected] and the Society will share as many stories as possible. On the 11th of April, BBC Radio 4 Feedback presenter Andrea Catherwood looked at why the Long Wave frequency is being shut down by the BBC. She interviewed RSGB President John McCullagh, GI4BWM, and in the final programme, a brief clip was used in which John gave his opinion on the possible impact for some listeners. You can listen to the Feedback show on BBC Sounds, by searching for “Feedback and Long Wave” on the BBC website. The feature starts at 19 minutes and 55 seconds, with the RSGB President featuring at 22 minutes and 18 seconds.

Using SSB on the 80m band, the exchange is signal report and serial number. On Thursday the 18th, the 70MHz UK Activity Contest runs from 1900 to 2130UTC. Using All modes on the 4m band, the exchange is signal report, serial number and locator.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of April 2024 The Sun is still looking a little bare, but the solar flux index has climbed back to 131, as of Thursday the 11th, with four active regions. The promise is that things will improve, especially as we will soon see the return of active region 3615, which was the source of numerous M-class and one X-class flare on its last rotation. Things have been a little sparse on the higher HF bands, with only FT8 being audible or visible on the 10m band at times. Having said that there has been some good FT8 DX to be worked on the 10m band, including Angola, Malawi, China, Japan, Taiwan and the Solomon Islands. During the recent solar eclipse event there were also a lot of US stations on the 10m band using WSPR. These included Bob, K6XX in Santa Cruz, California, who was copiable in the UK at around 1850UTC. This just shows how effective WSPR is as a mode on an otherwise quiet band. There have been some early signs of Sporadic-E on the 10m band using digital modes, including some brief openings to Scotland from eastern UK. We can expect these to improve as we head towards May. Next week, NOAA predicts that the solar flux index will be in the 140 to 150 range with a maximum Kp index of three. If this is correct it means that HF conditions will be roughly the same as last week. And now the VHF and up propagation news from G3YLA and G4BAO The weather patterns are showing signs of change after being stuck for quite some time, and the main beneficiary will be VHF operators seeing a chance of Tropo returning to the bands.  The initial unsettled weather over the UK, with high pressure fixed over the continent, will take us through to the middle of the coming week. Thereafter, a high will develop to the southwest of Britain midweek and drift northeast across the country, although some models take the high on a more southerly track. In either event, there should be some useful Tropo in the south and possibly northern areas too. This may be limited to southwestern areas for Tuesday's 23cm UK Activity Contest, but will hopefully be more supportive of the 4m UK Activity Contest on Thursday. Meteor scatter is worth a look next week since we are approaching the 21st and 22nd of April peak of the Lyrids shower at the end of next weekend. The quieter solar conditions have taken aurora down the table, but it's still good practice to watch out for if the Kp index goes above five. Gigahertz-band rain scatter certainly drops down the league table next week as high pressure probably takes over. As we said earlier, the next big thing is the start of the 2024 Sporadic-E season, which slowly comes to life during April for the 10 and 6m bands, especially on digital modes, whereas the real shift up in gear often comes during May. As mentioned last week, it’s worth updating your list of beacons in your rig’s memory while it’s still quiet. For EME operators, Moon declination is at maximum this weekend, ending the 14th, so there will be long Moon windows. We are past perigee, so path losses are rising again. 144MHz sky noise is moderate this weekend then low for the rest of the week. And that’s all from the propagation team this week.

The event is held to commemorate the almost 100 years of wireless telegraphy service for seafarers which ended with the closure in the UK of Portishead Radio on the 30th of April 2000. Commencing at 1200UTC on the 14th of April, and finishing at 2300UTC on the 15th of April, this event is a great opportunity to have a QSO with ex-Marine Radio Officers and Coast Station professionals who exchange details of their previous ships and coast stations. The mode of operation is CW and all of the HF bands are used, including the WARC bands. A certificate of participation will be issued to everyone who submits results. Amateur licence holders are invited to register to take part in Friends of Maritime Radio Day. Shortwave listeners may also submit logs. For more information and to register, visit tinyurl.com/MRD24 Lots of stations are on the air today to join in with this year’s Airfields on the Air event. Amateurs are invited to contact as many of the stations as possible. To learn more about the event, and read a list of registered stations, visit tinyurl.com/2024AOTA Tomorrow, the 8th, a total solar eclipse will head toward the UK from the west. While not visible over the UK, it will likely affect transatlantic VLF and HF radio propagation. RSGB Propagation Committee associate member Gwyn Griffiths, G3ZIL has a particular interest in the effect of reduced ionisation during the eclipse on second and third hops on 15 to 10m paths from the UK to North America. He encourages occasional WSPR users to dust off their transmitters to operate on those bands from today, the 7th, through to Tuesday the 9th of April, not just on the 8th, to provide results on undisturbed days.   And now for details of rallies and events Holsworthy Spring Rally is being held today, Sunday the 7th of April, at Holsworthy Livestock Market in Devon. The doors open to traders from 8 am, and to the public from 10 am. Wheelchair access, catering and free parking are available.

With a near-total lack of sunspots and a solar flux index of 112, the solar disk was looking pretty bare. Compare that with just two weeks ago when the solar flux index was sitting at 209 on the 23rd of March. But never fear, there seems to be some activity coming up. Two active regions, AR3627 and AR3628, have just rotated into view, but in the meantime make the most of the geomagnetically-quiet conditions. 10m propagation is still holding up, although you may find that the band opens a little later in the morning and shuts earlier in the afternoon. The 4X6TU and VK6RBP IBP beacons were both audible at 0945UTC on Thursday the 4th, while China, Japan, Mongolia and Thailand were copiable on 10m FT8, even with a lowish solar flux index. Higher HF band propagation from the UK has moved from favouring North America to north-south paths, notably to South Africa and South America. Next week, NOAA predicts that the solar flux index will rise a little, perhaps starting at around 135 and finishing at around 150. Geomagnetic conditions should be reasonably quiet with a maximum Kp index of 3, unless we get a coronal mass ejection that could send it soaring. As always, keep an eye on solarham.net  for current conditions. And now the VHF and up propagation news from G3YLA and G4BAO There have been reports of trans-equatorial QSOs on 144MHz from Southern Africa to the Southern Mediterranean, but here in the UK we can only dream due to our northerly location. The next period of weather is unfortunately shaping up to be the same as most of the recent ones, dominated by low-pressure systems driving active weather fronts across the British Isles. It means that Tropo conditions seem unlikely to feature much through to the end of the coming week. Rain scatter for the GHz bands remains the mode of choice with help from some heavy April showers. Meteor scatter options are still best with random meteors before dawn, but we are getting closer to the April Lyrids shower later this month, so not long to wait now. The solar conditions have subsided a little recently, but we remain in scope for further activity, especially since April can be one of the more active months for Aurora. Watch out for fluttery signals on HF or VHF bands, use the various clusters, or save the frequency of one of the northern beacons in your rig’s memory. This is a good time to suggest updating your list of favourite beacons on the 10, 6, 4 and 2m bands since they’ll be useful for the upcoming sporadic-E season too. It’s a good time to take an early look at the sporadic-E prospects before it gets properly busy.  Some background rules which may help are to use propquest.co.uk to see where the jet streams are since Sporadic-E propagation is often associated with turbulence in regions of jet stream activity. Then look for a relatively low Kp index. The other main rules are related to timing. Usually, there are two windows of opportunity, one in the morning and a second in the late afternoon or early evening. However, at the beginning of the season, these are approximate.  Sporadic-E starts on the lower bands like 10m and, if strong enough, will gradually extend to the higher bands. The 10 and 6m bands are probably the ones to check this month. For EME operators, Moon declination goes positive again on Sunday, which is also Moon perigee, its closest point to Earth, so we’ll see lengthening Moon windows, increasing elevation and low path losses. 144MHz sky noise is low until Monday’s total solar eclipse, then moderate for the rest of the week. And that’s all from the propagation team this week.

Club and multi-operator stations can only score points in either one of the operating periods. Entries need to be with the contest manager by the 17th of April. The full rules are available on the Worked All Britain website.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 27th of March 2024 What a tumultuous time we had last week. Active region 3614 produced an X1.1 solar flare and coronal mass ejection, or CME, in the early hours of the 23rd of March. This impacted Earth’s geomagnetic field sending the Kp index to 8 on the 24th of March. There were simultaneous flares from active region 3614 and the larger region AR3615. The solar wind speed reached more than 850 kilometres per second at the height of the geomagnetic storm, peaking at 880 kilometres per second. The CME started to impact the Earth early in the afternoon of the 24th and, according to Digisonde data, its full effects on the ionosphere started to be felt by 1540UTC. The large AR3615 sunspot cluster continues to evolve as it moves into the Sun’s southwest quadrant. Moderate flaring will remain likely in the short term with a lower chance for another strong X-class flare, although it is around the side of the Sun and is not considered a threat today, Sunday the 31st. All this was not good news for HF propagation, which saw maximum useable frequencies over a 3,000km path plummet on the 24th to less than 18MHz. The ionosphere didn’t fully recover until two days later, with the MUF struggling to get above 18MHz on the 25th. It wasn’t until the afternoon of Wednesday the 27th that we saw the 10m band behaving normally again with the Kp index back in the range of 1 to 3. So, this is what can happen if we have an X-class flare and associated CME. We can expect more of the same to come. Next week, NOAA predicts that the solar flux index will remain high at around 175 to 190. Unsettled geomagnetic conditions are forecast from the 3rd to the 5th of April when the Kp Index could rise to 4. But keep an eye on solarham.net for a near real-time guide to current solar conditions.   And now the VHF and up propagation news from G3YLA and G4BAO The period leading up to the Easter Weekend, and the following week shows up on the forecast charts as dominated by low pressure, feeding several periods of rain and showers across the country.  This unfortunately means that Tropo is again off the menu of weather-related VHF propagation. Of course, wet weather is usually very supportive of rain scatter propagation on the GHz bands and this prolonged period of rain or showers will give the UHF and SHF operators something to occupy their time. Meteor scatter prospects are once again just random, which tends to be better in the hours just before dawn. We can start to look forward to the April Lyrids, which are active in the second half of April with a peak around the 22nd. It’s worth checking out the operating conventions and frequencies now so that you can be ready. Strong aurora has been reported recently, with a Kp index of 8, and a quick listen for fluttery signals on the 80m or 40m bands is often a good clue if you don’t have access to the Kp index at the time. The main mode of interest for the coming months is Sporadic-E and some early propagation is possible, mainly on digital modes on the 10m or 6m bands, but probably very fleeting.  During the summer Sporadic-E season, it's well worth checking the propquest.co.uk  graphs to see what is occurring and get an idea of how it may relate to jet stream weather patterns by cross-checking with the Sporadic-E blog upper air charts. The Sporadic-E Probability Index, or EPI, maps are also potentially useful to see how the favourable regions change with time. In the current pre-season period, it’s more typical to find trans-equatorial propagation, or TEP, as an exotic mode offering paths to the south into South Africa and possibly into South America. For EME operators, Moon declination reaches minimum on Easter Monday, so we’ll see short Moon windows with low elevation. Path losses are falling all week and 144MHz sky noise is moderate, rising to a peak of more than 3,000 Kelvin on Easter Monday before returning to low levels. And that’s all from the propagation team this week.

Using SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 21st of March 2024 As we said last week – what a difference a month makes. Only in this case, what a difference a week makes! On Friday the 15th, the solar flux index, or SFI, was at 129 and the Sun did not look very spotty at all. This week it’s all changed. On Thursday the 21st, the solar flux index stood at 176 with seven active regions visible. For HF propagation forecasts, the golden rule is to use smoothed sunspot numbers, or SSN for short, rather than a daily figure – that is, sunspot numbers averaged over the past 12 months. The current SSN is 129, which equates to a solar flux index of about 144. Perhaps the daily figure of 176 has the psychological effect of giving us confidence that the bands will be open! A moderately strong M7.4 solar flare was observed around active region 3615 at 0736UTC on the 20th of March. The region continues to rotate into a better Earth-facing position and will remain a threat for additional solar flares above the M5.0 threshold. If a flare leads to a coronal mass ejection or CME, we could expect a disturbed ionosphere roughly 48 hours later, depending upon the solar wind speed. Also, a large coronal hole on the solar equator became Earth-facing on Thursday the 21st. A coronal hole is a lower-energy area on the Sun with open magnetic field lines that let solar plasma escape. This may lead to a geomagnetic disruption this weekend, ending today the 24th, with increased Kp numbers and a lowering of the maximum usable frequency. Next week, NOAA predicts that the SFI will be in the 155 to 165 range. Geomagnetic conditions are hard to predict, due to coronal hole effects and CMEs, but NOAA puts the Kp figure at two to three. If we get a CME, this could easily rise to five or more. Finally, we are now at the equinox which means that auroras are more likely due to the Russell-McPherron effect. The equinox is also a good time for north-south HF paths. Also, note that the HF bands are staying open for longer with the 4U1UN beacon in New York, the YV5B beacon in Venezuela, and the 4X6TU beacon in Israel audible on 14.100MHz around 2230UTC last week. And now the VHF and up propagation news from G3YLA and G4BAO It’s not good news for weather-related propagation with a total absence of high pressure on the charts again and a resulting lack of Tropo for the majority of the coming week. But Tropo is not the only mode to be affected by the weather, rain scatter is too. This has been a player quite often recently and, as we move into the spring, the characteristic ‘April showers’ can be very useful for rain scatter. Their effectiveness is related to the sixth power of the raindrop diameter, so the larger drops in heavier ‘April showers’  can be increasingly valuable on the GHz bands. Many good online weather radar displays are available to allow you to track them for maximum benefit. Other promising mentions should go to Aurora which, as we said earlier, can be more likely around this time of the year when the Earth’s magnetic field is more favourably coupled to the solar wind. Meteor scatter is a lesser option and rests with random chance activity as we are still some way off from any major meteor showers. Sporadic-E and related Trans-Equatorial Propagation, or TEP, in the shorter term during the next month or so, will soon be a major player. For TEP between Europe and southern Africa, check clusters around the middle part of the day. Although usually favouring stations in southern Europe, it can occasionally turn up for UK operators, particularly for those located in the southern half of the country.  As for Sporadic-E, the new season is starting to wake up, so the usual maxim of checking clusters is the best advice, starting with the 10m band and working up to the 6m band. The traditional morning and late afternoon ‘windows' are less reliable in early-season events, so just check anyway if you’re in the shack. For EME operators, Moon declination is still positive, but going negative again this coming Monday. Path losses are at their maximum due to apogee on Saturday the 23rd. 144MHz sky noise is low but rising to moderate by the end of the coming week, reaching more than 1,000 Kelvin on Sunday the 31st. And that’s all from the propagation team this week.

GB2RS News Sunday the 17th of March 2024 The news headlines: The RSGB’s 2024 AGM is coming up British Science Week is drawing to a close Changes to examination fees are coming soon This year’s RSGB AGM will take place at 10 am on Saturday the 13th of April and will be held online to ensure as many members as possible can watch and take part. The formal business of the meeting will include the results of members’ votes on the resolutions, including the endorsement of three Nominated Directors. The President will give a video review of 2023 and the Society will announce the recipients of its annual awards and trophies, as well as the winners of its construction competition. At the end of the meeting, there will be a recorded presentation on “Making amateur radio licensing fit for the future” by Ofcom Group Director, Spectrum, David Willis. This will be followed by a live Q&A on the new licence conditions, with four senior RSGB representatives answering your questions: President, John McCullagh, GI4BWM; Board Chair, Stewart Bryant, G3YSX; General Manager, Steve Thomas, M1ACB; and Spectrum Forum Chair, Murray Niman, G6JYB. You can find more information about the candidates, voting and how to ask the Board a question on the RSGB AGM web pages at rsgb.org/agm British Science Week is drawing to a close and lots of exciting activities have been going on. Radio amateurs across the country have been encouraging young people to explore and understand our hobby and there have been some wonderful ways of incorporating the theme of “Time” into amateur radio activities. The RSGB would like to thank those who have shared ideas and resources, promoting the magic of radio communications with young people. There will be a report in the June issue of RadCom to showcase the activities that have happened and to inspire people to get involved next year! Perhaps you ran a construction day, set up and operated a radio station in a school or achieved a QSO with GB3RS at the RSGB National Radio Centre. Whatever you’ve been doing, please send your reports, with separate high-resolution photographs, to [email protected] by the 21st of April 2024. The RSGB would welcome feedback about what worked well, what you learned and how the Society could develop its British Science Week activities next year. Please email the RSGB British Science Week Coordinator Ian Neal, M0KEO at [email protected] to share your thoughts. Early in February the RSGB announced that the fees for Foundation, Intermediate and Full level examinations would increase from the 1st of May 2024. You can now use the online booking system to book an exam before the 1st of May at the current price or select exam dates from the 1st of May at the new prices. Please ensure you make the correct date selection, as booking errors that need to be changed may incur an administration fee as outlined in the exam terms and conditions. To book an exam, go to the Student Information section of the RSGB website and choose the option to book and pay for your exam from the right hand menu. The RadCom Contesting column has new editors! The RSGB Contest Committees will be overseeing the column and have planned a schedule of topics. Some will be written by members of the three contesting committees, and some by others who can share their experiences. As well as information about various aspects of contesting, the committees hope that the column will feature a contesting tip of the month, a featured UK contester, as well as a contest of the month. Once each issue is published, the column content will be shared on the RSGB website to provide a useful resource about contesting. You can see a list of the planned topics at rsgb.org/radcom-contesting  The committees are keen to hear from people who would like to be involved, so if you would like to suggest a missing topic or offer to write something for the column, please email [email protected] And now for details of rallies and events Callington Radio and Electronics Rally is taking place today, the 17th.

Using all modes on the 4m band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of March 2024 What a difference a month makes. We’ve gone from a solar flux index up to almost 200, to one that is down in the 120s. Over the past week, we have had only two M-class solar flares, which means we have had limited coronal mass ejection activity and therefore low Kp indices. Last weekend’s Commonwealth Contest saw UK amateurs making plenty of HF contacts, some with Australia, but everyone agreed that HF propagation was a little lacklustre. There is a daily chance of moderate-class solar flares from AR 3607, the largest sunspot region, but all remaining spots remain mostly small and simple. The solar wind speed has been quite high with sporadic periods of a south-pointing Bz field. This is what has pushed the Kp index to three, but this isn’t a big threat to HF. There is a slight chance of unsettled intervals caused by a weak coronal hole near the south centre of the solar disc coupled with the fast solar wind. NOAA reports that active region 3590 has been detected on the far side of the Sun using helioseismology. This may mean that it will still be active and a threat when it returns in a week or so. This region was the source of the X6 solar flare on the 22nd of February – the largest so far in solar cycle 25. Next week, commencing the 18th of March, NOAA predicts that the solar flux index will remain in the 120 to 130 range, although the US Air Force predicts it could reach 150. Geomagnetic conditions are likely to be mainly settled with a maximum Kp index of two or three.  So, this is a reasonable forecast for HF propagation, which should remain open up to 28MHz during daylight hours. This is also a good time for north-south paths, such as the UK to South Africa, and the UK to South America. And now the VHF and up propagation news from G3YLA and G4BAO The continuing theme of unsettled weather will produce further spells of rain and heavy showers and once again provide some rain scatter options on the GHz bands. Another thing to mention is that, as we move towards the latter part of the month, the intensity of showers becomes greater due to the additional warmth improving the effectiveness of the rain scatter process. It is very hard to find any traditional Tropo until we get well into the coming week. It may occur on Thursday the 21st when a high will develop a ridge from Biscay across southern Britain and the near continent. This should provide a chance of Tropo for the final few days of the coming week. Unfortunately, this is not in time for the UK Activity Contest on 1.3GHz on Tuesday the 19th, but the 70MHz UK Activity Contest on Thursday the 21st may be luckier. The north of Britain may start to see the next low bringing rain over that weekend, so although it has an early exit from any Tropo, at least being well north gives Scottish stations a head start for any aurora, which tends to favour the spring months. Meteor scatter remains in the random territory – try just before sunrise for best results. But with the next major shower being the Lyrids in late April, we have a while to wait for an uptick in activity. Lastly, a brief mention of Sporadic-E. It has popped up with some weak events on the Dourbes plots on Propquest, but the main season is still a little way off. Maybe check next month for a heads-up on the lower bands like 28 and 50MHz. Of course, digital modes will get a head start, so best to check the clusters and chatrooms for signs of fleeting activity. Some UK stations reported 50MHz trans-equatorial propagation to Africa last week, so check for that. For EME operators, Moon declination reaches a maximum on Sunday, but path losses are starting to increase again. 144MHz sky noise is moderate, falling to low on Wednesday. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 10th March 2024

GB2RS News Sunday the 10th of March 2024 The news headlines: New rules for HF contests are in place Applications are open for this year’s YOTA camp Listen out for operators taking part in British Science Week   The RSGB HF Contest Committee has introduced a couple of rules to address changes in licence conditions that came into effect on the 21st of February. It has also highlighted power changes to specific contests. The committee is introducing a section for Foundation licensees in some of its contests now that the power limit is increased to 25W. Before finalising the rules for 2025, the committee will consult widely on whether Regional Secondary Locators should remain mandatory in those contests for which the country in which the operator is situated has no bearing on the score. For more details see the RSGB Notices section on the RSGB website. Are you aged between 18 and 25 and passionate about all things radio? Are you ready for exciting experiences, making new friends and shaping the future of amateur radio? Why not apply to be part of the RSGB YOTA team going to the YOTA Czechia summer camp this year? You can find out more on the RSGB website. Go to rsgb.org/yota and click on the ‘YOTA Summer camps’ link in the righthand menu. You’ll be able to read about the experiences of previous teams and download an application form for the Czechia event. The closing date for applications is the 15th of April for the Team Leader and the 22nd April for Team Members. British Science Week started on Friday the 8th of March and continues until Friday the 17th of March. Please have a look at the list of times that participants will be on the air and try to respond to them. These will nearly all be students who will be making their very first QSOs working with local amateurs. Your contact will make their day and might lead to new radio amateurs!

The British Amateur Radio Teledata Group HF RTTY Contest starts at 0200UTC on Saturday the 16th and ends at 0200UTC on Monday the 18th. Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is signal report, serial number and locator.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 7th of March 2024 As predicted, a coronal mass ejection, or CME for short, affected the ionosphere last weekend, the 2nd and 3rd of March, pushing maximum usable frequencies down and sparking auroral displays that were visible as far south as Cornwall. The plasma hit the Earth around midday on Sunday the 3rd, eventually pushing the Kp index to more than 5 for nine hours. It eventually started to settle again, dropping to 4 for six hours, before then moving back to background levels by the morning of the 4th. The solar wind speed was not that high, being around 350 kilometres per second, but the Bz component of the interplanetary magnetic field, or IMF, was pointing sharply south for a long period. This allowed the solar plasma to couple with the Earth’s magnetic field more easily, and it flooded in. The maximum usable frequency was impacted, and it took until late morning on the 4th  before the 10m band was usable again over a 3,000km path. This probably impacted northerly paths the most with southerly paths being relatively unscathed. The rest of the week was generally free from coronal mass ejection chaos with the Kp index remaining below 3. Attention is now turning to active region 3599, which has expanded in size. It may therefore be a threat for an M-class solar flare and potential CME. Next week, commencing Monday the 11th, NOAA predicts that the solar flux index will be around 135, but may then increase to 170 by the 15th. We are heading towards the equinox, which means that geomagnetic disturbances are likely to be more common and harsher. They are almost twice as likely in spring and autumn versus the winter and summer. If the Kp index stays low, though, this can be a good time for HF. And now the VHF and up propagation news from G3YLA and G4BAO This weekend, the 9th and 10th, a strengthening southeasterly wind will develop over the country as low pressure moves into Biscay and a strong high builds over Scandinavia. Unfortunately, this may not be useful for Tropo since the high is a long way to the northeast and stronger winds usually prohibit the development of a quality inversion. All this changes again over this second weekend of March, the 9th and 10th, as low pressure pushes fronts into southern Britain. It won’t last long though and a weak ridge will cross the country on Tuesday the 12th, which may bring some Tropo support for southeastern Britain into the continent for the 432MHz UK Activity Contest on Tuesday evening. On Wednesday, an Atlantic low will cross northern areas with rain and possible rain scatter options, but this will soon clear to leave a weak high over the country and it’s a return to Tropo conditions for the remainder of the week. The upshot of all this is that Tropo will be an off-and-on affair, but worth a look. The other modes, not so much. Although, as we said in the HF section, spring is a good time of the year for auroral activity and, after the recent visible aurora, we should keep a watch for activity and a high Kp index. There has been the odd fleeting pulse of Sporadic-E showing on the Propquest graphs recently. This has been noticeable on the LF bands sometimes but is not yet a big player for the usual Sporadic-E bands of 10m, 6m and beyond. However, on digital modes, UK stations have seen 50MHz trans-equatorial propagation, or TEP, to Africa last week – so check for that. For EME operators, Moon declination is still negative but goes positive again on Monday. Path losses are approaching minimum with perigee today, Sunday the 10th. 144MHz sky noise is low all week except today, the 10th, when the Sun is close to the Moon and in the beamwidth of antennas. And that’s all from the propagation team this week.

Voting opens on Wednesday the 13th of March. On that same day, you will be able to submit a question for the RSGB Board via a web form or register to ask a question via video on Zoom. For more information go to the Society’s website at rsgb.org/agm The RSGB’s Propagation Studies Committee has released a new HF beacon list, with the 10m band listings completely revamped. The old list, which was started by Martin Harrison, G3USF Silent Key, had been added to over the years but was getting out of date. The only way to make it more accurate was to start again. The Propagation Studies Committee made use of the Reverse Beacon Network which wasn’t available when the list was originally created, plus listeners’ contributions from around the world. The new beacon list can be found at rsgb.org/beacons Have you wondered what happens at a VHF National Field Day? Would you like to take part in one? In this month’s Tonight@8 webinar, on Monday the 4th of March, the RSGB offers two different perspectives. Firstly, RSGB VHF Contest Committee member Richard, G4HGI will talk about how the RSGB VHF Contest Committee uses the VHF Survey and other tools to formulate the rules and calendar for all VHF Contests, with specific emphasis on VHF National Field Day. Secondly, three members of the Lothians Radio Society, GM3HAM will explain how they organise and operate these hilltop events within the Scottish borders. The club has made a short, professional film capturing their 2023 VHF National Field Day weekend. They will show clips of that and of an old cinema film to show how this looked from a technical standpoint at much earlier club competition events in the 1970s. This will be a great evening so put it in your diary and be inspired! You can watch and ask questions live on the RSGB YouTube channel or a special BATC channel. Go to rsgb.org/webinars to find out more. The RSGB has made two safeguarding announcements. Firstly, the Society’s safeguarding policy has been revised in line with modern practices and you can find it on the RSGB website at rsgb.org/policies  Secondly, if your club relies on the RSGB’s affiliated club insurance for activities that may have a safeguarding requirement, it is important that you are aware of the conditions in Section 10 of that insurance. You can find the insurance details in your club portal on the RSGB website. The Radio Society of Harrow is running a one-day classroom-style Foundation course on Saturday the 23rd of March at its venue in Watford. If you know anyone who would like to join the course, please tell them to email Brian, G3YKB at [email protected]  There will be an optional extra session on the morning of the 24th. Following complaints from some members, the RSGB has investigated a problem with the non-delivery of RadCom on Guernsey and the Isle of Man. It seems that following changes at Royal Mail, the labelling requirement for these copies was incorrectly applied by the printers and these copies didn’t go through the postal system correctly. The Society is sorry that this error has occurred and apologises for any inconvenience caused. It has, of course, asked its printers to ensure that there is no repetition of this problem, and the printer has paid for the two missing copies to be sent to each RSGB member in those areas. If your RadCom doesn’t arrive in future, please email the RSGB membership team via [email protected] so they can send a replacement and track any wider problems. Those who enjoy constructing and operating with low-power devices will be interested to know that a QRP conference is taking part in Rennes in the northwest of France on the 18th of May 2024. The event will include lectures and demonstrations and will be an ideal opportunity for the exchange of information between like-minded amateurs. The organisers are putting together a programme of speakers and are looking for contributors on every aspect of low-power design, construction and operation.

Using SSB on the 80m band, the exchange is your six-character locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 29th of February 2024 Active region 3590, which was the large sunspot group that threatened us with solar flares and coronal mass ejections, or CMEs, has now moved to the Sun’s limb and is no longer a threat. Region 3590 was potentially dangerous but ultimately wasn’t too bad. Yes, we had flares, but they were only minor C-class and M-class events. Three recent CMEs, which will all probably miss Earth, but with a risk of some glancing influence, are most likely to have arrived by this weekend, ending the 3rd of March. However, old active region 3576 will begin to turn into view off the southeast limb by the end of today, the 3rd. The Kp index rose to 4.67 during one three-hour period on Tuesday the 27th of February, but the disturbance was short-lived and HF propagation wasn’t too badly affected. Speaking of which, there have been some good HF openings to the Pacific area over the last week. Spotted have been 3D2AG in Fiji on the 17m band, VK on the 10m band, and the H40WA Temotu DXpedition to the Solomon Islands. This latter DXpedition has mostly been spotted on FT8 Fox and Hounds mode in the UK. The maximum usable frequency, or MUF, over a 3,000km path still remains above 28MHz during daytime, with MUFs over 14 to 15MHz at night. So, as we head into March and towards the spring equinox, HF is still looking good. Next week, NOAA predicts the solar flux index will be in the range of 165 to 170. The Kp index is predicted to be two all week, but that is suspect and dependent on coronal mass ejections – or a lack of them. At this point in the cycle, anything could happen. With six or seven active regions visible, the risk of a flare and CME remains relatively high. And now the VHF and up propagation news from G3YLA and G4BAO The overall weather pattern remains very unsettled with further active lows and weather fronts crossing the country. There will also be periods with stronger winds and it may be cold enough for some wintry weather, especially over northern hills. The upshot of all this is that Tropo will once again be a rarity, but rain scatter may offer some comfort to those on the GHz bands. Later in the coming week, high pressure will strengthen over Norway and this will produce quite strong winds over the North Sea and eastern UK and perhaps encourage paths to the east, but it’s probably marginal at best in terms of Tropo. The prospects for aurora and meteor scatter are not especially reliable, but it was encouraging to hear of some digital activity on the 6m band earlier in the week to South Africa and Lesotho. This was probably the result of Trans Equatorial Propagation or TEP, as suggested in last week’s news. The spring period is a fairly good time to listen for TEP, timed between the decay of the southern hemisphere summer Sporadic-E season and the start of the northern hemisphere summer Sporadic-E season. It’s well worth checking for similar activity during March for paths to the southern hemisphere via TEP. Signals can be strong enough for SSB or CW modes, so it is not exclusively for digital modes. For EME operators, Moon declination drops to a minimum on Tuesday. Path losses are past their peak now and falling until perigee on Sunday the 10th. 144MHz sky noise is moderate to high, reaching a peak of over 2,500 Kelvin on Tuesday the 12th. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for February 25th 2024

GB2RS News Sunday the 25th of February 2024 The news headlines: New amateur radio licence conditions are effective Amateurs are reminded to carry out EMF assessments The 2024 Band Plans have been published Ofcom has released its final decisions following its consultation on the amateur radio licensing framework last year. Revised licence conditions became effective on Wednesday the 21st of February 2024. The changes to licence conditions include the optional use of Regional Secondary Locators, increased transmitter power levels and provide a greater opportunity to bring newcomers into amateur radio. There are approximately 100,000 amateur radio licences issued by Ofcom in the UK. Ofcom says that it will shortly be contacting all licensees to provide each with their new licence document. Ofcom is aiming to reissue all UK amateur radio licences by the autumn of 2024. To help this process run as efficiently as possible, please ensure that your contact details are up to date in the Ofcom licensing system. Further updates to the amateur radio licensing framework, including the issuing of M8 and M9 Intermediate callsigns, will be rolled out in two more phases later this year and in the 2024/25 year. A video entitled ‘Updating the amateur radio licensing framework: RSGB overview of key changes’ is available in the Ofcom playlist on the RSGB’s YouTube channel which you can find at youtube.com/theRSGB  In it, RSGB General Manager Steve Thomas, M1ACB and RSGB Spectrum Forum Chair Murray Niman, G6JYB discuss the impact of the new rules. They also describe how the RSGB worked with Ofcom before and during the consultation period to arrive at the best outcome for all UK amateurs. Steve, Murray, and many people across the RSGB have also worked hard to engage with individual amateurs, and amateur radio clubs and groups, to help them prepare for the licensing changes. The RSGB will continue to release information and support for radio amateurs as we all adapt to the new arrangements. You can read more details and guidance on the Ofcom website at tinyurl.com/ARFEB2024 or via the RSGB website at rsgb.org/licensing Given that increased transmitter power limits are now available to UK licensees, all amateurs are reminded that they are required to carry out EMF assessments. To help you do this, advice and an online EMF calculator can be found at rsgb.org/emf The RSGB Band Plans for 2024 were published in the March issue of RadCom. They are also available via the RSGB website at rsgb.org/bandplans  This year’s changes support the new Ofcom licensing framework and guidance, particularly in the VHF and UHF bands. All amateurs are reminded to consult the Band Plans before operating. The list of amateur radio events taking place in British Science Week and the resource suggestions are growing. GB3RS, the radio station at the RSGB National Radio Centre at Bletchley Park could be available for QSOs with stations operating as part of British Science Week. Contact the RSGB’s BSW coordinator, Ian Neal, M0KEO at [email protected] and he will link you with the NRC Coordinator Martyn Baker, G0GMB to make your arrangements. Please continue to send to Ian the resources you’d like to share and details of British Science Week events you’re organising, including the times you’ll be on the air. The RSGB would like to inspire as many people and groups as possible to get involved! You can access all event and resource details on the RSGB website at rsgb.org/bsw The RSGB has been trialling paper wrappers for RadCom as part of its plans to be more environmentally friendly. The Society has been collating feedback and is aware that there have been particular problems with the glueing of the RadCom wrappers this month. Please be assured that the RSGB is discussing this with its supplier to try to resolve the problem before the next issue. During a year when the global landscape shifted once more, with conflicts across the world and economic difficulties touching the lives of individuals, the RSGB was pleased to see that the amateur radio community continues to thrive. It may have changed shape and adapted with the times, but the Society has been there not only to support its members but to defend the spectrum and provide information for all radio amateurs. In the March RadCom, there is a feature called ‘A year in numbers’ which shows some of the great things to celebrate, in which RSGB HQ staff have often led the way. There is an infographic and a short video with the highlights, and you can read the fuller story from page 40 in RadCom and on the website. Go to rsgb.org/strategy-updates and click on “2023 - a year in numbers”. The April RadCom will show in detail the work of the RSGB committees and other specialist volunteers. The amateur radio licence exams will be updated in line with the new licence conditions decided by Ofcom this week. Further information about the timing of those changes can be found on the RSGB website at rsgb.org/syllabus2019 Registration is open for the Mills on the Air event which will take place on Saturday the 11th and Sunday the 12th of May.

Please note that this is an SSB-only contest, and the exchange is signal report, serial number and Worked All Britain area. All entries need to be with the contest manager by the 13th of March. Full Contest rules are available on the Worked All Britain website at worked-all-britain.org.uk The ARRL International DX Contest starts at 0000UTC on Saturday the 2nd of March and ends at 2359UTC on Sunday the 3rd of March. Using SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and transmitter power. American stations send their state and Canadian stations send their province.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 22nd of February 2024 We’ve had two X-class solar flares over the past few days. The first occurred at 2307UTC on the 21st of February, so didn’t affect the UK at all. The second erupted at 0632UTC on the 22nd of February and was too early to affect the ionosphere in this region. However, HF paths to the east may have been affected. However, active region 3590 could cause more problems as it rotates into an Earth-facing position. Look out for more flares and potential coronal mass ejections as we head into the weekend. Another problem is a coronal hole on the solar equator, which was Earth-facing on Friday the 23rd and could lead to an increased Kp index today, the 25th if its associated Bz magnetic field points south. Although there are only two sunspot groups visible, the solar flux index is 170, showing just how potent these spots are. Daytime MUFs over a 3,000km path are still exceeding 35MHz, while nighttime MUFs over a similar distance struggle to get above 10 to 11MHz. With the daytime MUF so high, it is a good opportunity to check for low-power 10m beacons. The RSGB’s Propagation Studies Committee has just released a new 10m beacon list, which has been created from scratch using the reverse beacon network and help from amateurs around the world. The new beacon list, which can be found under the Propagation section of the RSGB website at rsgb.org/beacons should be more useful than its predecessor as it is based on actual beacons that have been received. But if you hear any beacon that is not on the list, please inform Steve, G0KYA at [email protected] Next week, NOAA predicts that the solar flux index may decline a little into the 160s. As for geomagnetic conditions, it all depends upon what happens with active region 3590. We could be in for a rough ride, or things could be fine – let’s wait and see. And now the VHF and up propagation news from G3YLA and G4BAO The current spell of unsettled weather continues, and this means that Tropo won’t be worth waiting for, other than any temporary short-lived early morning temperature inversions, especially if accompanied by misty low cloud or fog. The main part of the story is again rain scatter, which will have plenty of opportunity to shine in the period to the end of the coming week. Summer thunderstorms are usually full of large raindrops, while winter systems are generally less intense but, in the absence of much else, it’s still worth considering for those on the GHz bands. The other propagation modes of meteor scatter or aurora are even longer shots, but they may still crop up. The best time for random meteor scatter QSOs is around dawn. Lastly, the doldrums for Sporadic-E propagation are still with us and don’t expect too much until we are well into April, even on the 10m band. The high solar flux could see some trans-equatorial 50MHz openings if the Kp index remains low, especially for the far south and west of the UK.   For EME operators, Moon declination starts the weekend positive but drops negative again on Monday. With apogee, when the Moon is at its furthest point from Earth, occurring yesterday, Saturday the 24th, path losses are at their highest for the month this weekend. 144MHz sky noise is low all week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 18th February 2024

GB2RS News Sunday the 18th of February 2024 The news headlines: Ask the RSGB Board a question during the Society’s 2024 AGM Get involved with British Science Week Registration is now open for Maritime Radio Day 2024   Over the last few years, the RSGB has been developing the way in which the Board can be asked questions at the Society’s online AGMs. Last year people were able to ask questions via the YouTube live chat as well as submitting written questions in advance. This year, in response to members’ feedback, there will be an opportunity to ask a question on video via Zoom. The RSGB Board will still take written questions in advance and will also answer as many questions on the day via the live chat as possible, depending on the time. The RSGB AGM will be held on Saturday the 13th of April and you can find more information about how to take part on the Q&A subpage of the RSGB AGM web section at rsgb.org/agm The RSGB has a collection of resources to help you get involved with British Science Week, which runs from the 8th to the 17th of March this year and has the theme of ‘Time’. If you already have something planned, please let the RSGB know. This will be useful for others to see and might inspire them! There are already several events for British Science Week on the RSGB website. Some of these are open to everyone, so please show your support for them. If you’re going on the air, tell everyone when to listen out for you by sending the RSGB dates, times, bands and modes. The RSGB’s British Science Week coordinator is Ian Neal, M0KEO and you can contact him via [email protected]  Please send Ian the resources you’d like to share and your event details including the times you’ll be on the air. All details are on the RSGB website at rsgb.org/bsw Registration is now open for Maritime Radio Day 2024 which takes place annually on the 14th and 15th of April. The event is held to commemorate the almost 100 years of wireless telegraphy service for seafarers which ended with the closure in the UK of Portishead Radio on the 30th of April 2000. Commencing at 1200UTC on the 14th of April, and finishing at 2300UTC on the 15th of April, this event is a great opportunity to have a QSO with ex-Marine Radio Officers and Coast Station professionals who exchange details of their previous ships and coast stations. The mode of operation is CW and all of the HF bands are used, including the WARC bands. A certificate of participation will be issued to everyone who submits results. Amateur licence holders are invited to register to take part in Friends of Maritime Radio Day. Shortwave listeners may also submit logs. For more information and to register, visit tinyurl.com/MRD24 There are less than two weeks to go until the deadline for the RSGB Construction Competition. There are six categories to enter this year: Antennas; Beginners; Most creative and/or elegant PCB Design; Construction Excellence; Innovation; and Software and Systems. To enable members from across the country, and even the world, to enter, entries will again be judged over the internet rather than in person. Special recognition will be given to entries submitted by radio amateurs under the age of 24, and to those who have just gained their Foundation licence. A cash prize will be awarded to the winner of each section, with a bonus for the overall winner, who will also be declared the winner of the Pat Hawker G3VA Award. You can find out more, including how to enter, on the RSGB website at rsgb.org/construction-competition  Don’t forget, the deadline for entries is the 1st of March 2024 so get your entry in before it’s too late. Many amateur radio stations have been on the air this weekend, in conjunction with The Guide Association, to celebrate World Thinking Day on the Air. The aim of World Thinking Day on the Air is to encourage Guides to make friendships with members of other units, using amateur radio as the means of communication. If you, or your club or society, were on the air during the event don’t forget to send your pictures and stories to [email protected]  Please send your reports in by the 23rd of March.

Using SSB on the HF bands, where contests are permitted, the exchange is signal report and serial number. French stations send their department number or overseas territory prefix. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 15th of February 2024 We had an interesting week with the threat of a major coronal mass ejection at any time with so much sunspot activity. In the end, it pretty much amounted to nothing, with the highest Kp index only reaching 4.33 on February 11th. That’s not to say we didn’t have solar activity. Far from it, as the solar flux index reached 208 on the 12th and has been consistently above 180 all week. We also had high proton levels as the positively charged particles streamed past Earth. This was the result of an eruption early on Monday morning from beyond the southwest limb. This may have affected HF signals going over the poles. Otherwise, we had numerous low-level solar flares to contend with, but none of them were stronger than M-class and so of little consequence. So where did this leave us in terms of HF propagation? All in all, not bad with maximum usable frequencies, or MUFs for short, over 3,000km consistently above 28MHz in daylight hours. Daytime MUFs were peaking above 33MHz according to the Dourbes ionosonde. Looking further ahead, we are now heading towards the equinox period, so we can expect MUFs to fall from their winter highs. The good news is that we can expect north-south paths to improve. The equinox is traditionally a better time for auroral conditions. If you want to work the USA on 28MHz you still have a couple of months left to do so, but expect transatlantic propagation conditions to decline by the time April arrives. The good news is that propagation to South Africa, South America and the Caribbean may improve. Next week, NOAA predicts that the solar flux index may reduce and be in the range of 155 to 165. Geomagnetic conditions are predicted to be quiet but, as always, keep an eye on solarham.net for a near real-time update as the risk of a coronal mass ejection, or CME, remains high. To recap, an Earth-facing CME could increase the Kp index, reduce MUFs and generally give poor HF propagation for up to a day.   And now the VHF and up propagation news from G3YLA and G4BAO The basic weather pattern remains unsettled with a series of frontal systems crossing the country during the period. This leaves little room for any Tropo other than the occasional transient ridge of high pressure between successive weather systems. It does however give plenty of scope for rain-scatter enthusiasts to try their luck on the GHz bands. The solar conditions continue to give hope for an increased geomagnetic Kp index, which would be a good signal for potential aurora if it goes above 5 as evidenced in visual displays over northern Britain last Tuesday night, the 13th and 14th of February. As usual, the other propagation modes can still surprise us, even though this is not strictly the best time of year. The large number of satellites in operation means that QSOs can be guaranteed even with simple hand-held equipment. So, have a look at the AMSAT-UK pages and the RSGB website for details and give it a go! Also, a reminder that the best time for random meteor scatter QSOs is around dawn and that the high solar flux could see some 50MHz openings if the Kp index remains low, especially for the far South and West of the UK.   For EME operators, the moon reaches peak declination today, Sunday the 18th, so activity should be higher with high peak moon elevations and long moon windows. Path losses are moderate but rising and 144MHz sky noise is moderate, but falling after Monday. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 11th February 2024

  GB2RS News Sunday the 11th of February 2024 The news headlines: The outcome of the RSGB 2024 Board and Regional Team election process RSGB challenge for British Science Week announced RSGB Spectrum Forum updates The RSGB has announced the outcome of its 2024 Board and Regional Team election process. These results come into force at the RSGB 2024 AGM and, until that time, the current Regional Representatives remain in their roles. The announcement also contains news of the Nominated Directors put forward for endorsement by the RSGB membership next month, as well as two co-options to the RSGB Board, effective until the AGM. For full details of the announcement and the candidates go to the RSGB AGM web page at rsgb.org/agm The theme of British Science Week this year is Time. Both time and the closely related concept of frequency, are of vital importance to radio communications. The RSGB has announced a new challenge for British Science Week linked to this theme. The challenge has categories for every age group and the winner of each group will win a prize. The deadline for entries is the 1st of September and the results will be announced at the RSGB Convention in October. The challenge is as follows: “Using readily available components, material or other resources, provide a method of either measuring the frequency of a radio frequency source or signal or providing a time reference to a radio operator or radio system”. For more details about the challenge, as well as activities to inspire you and resources to help you take part in British Science Week, go to the RSGB website at rsgb.org/bsw A busy year has seen several online Spectrum Forum meetings. Two meetings held in January considered the Ofcom notice period for ‘representations’ and areas where band plan adjustments would be needed, as well as more regular items such as annual group reports. The RSGB website now has these details online. The RSGB’s reply to Ofcom has been added to its special focus page on the Ofcom licence review. Along with other recent representations, this will enable Ofcom to finalise the new licence later this month. The RSGB Spectrum Forum pages have also been updated with the January 2024 group reports and meeting notes, which included the discussions on the provisional changes. To read more, visit rsgb.org/spectrumforum As previously announced by the RSGB Examinations Standards Committee Chair, Tony Kent, G8PBH, the amateur radio licence examinations will need to change to reflect the changes to the licence conditions announced by Ofcom. The scale of the licence changes will have a significant impact on Section 1 of the syllabus, ‘Licensing’, and a small impact on Section 7, ‘Operating’. Ofcom is currently reviewing representations and will publish its final decision, including the final version of the licence, before the 21st of February. The new licence will come into effect before work on the syllabus and examination question bank is completed. The RSGB Examinations Standards Committee has gained approval from Ofcom to continue to examine the current licence conditions for a period of six months following the publication of the new licence. This will allow trainers time to update their courses in line with the new syllabus, and allow candidates that have started their training under the current licence conditions to complete their courses and take the exam. It is expected that examinations of the new licence conditions will begin on the 1st of September 2024. For full details, see the exam announcements page on the RSGB website. The first amateur radio station on the moon, JS1YMG, is now transmitting. The Japan Aerospace Exploration Agency, or JAXA, landed its Smart Lander for Investigating the Moon on the 19th of January 2024. The JAXA Ham Radio Club, JQ1ZVI secured the JS1YMG callsign and has been transmitting Morse code on 437.41MHz since the 19th of January. The probe uses 1W to a UHF antenna, with circular polarisation, and is transmitting what is described as "matters related to amateur business." Radio amateurs have been busy analysing JS1YMG's signal. You can read more about this story on Daniel Estévez, EA4GPZ’s blog at destevez.net The RadCom team is looking for authors who are interested in antennas.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 8th of February 2024 A large sunspot region has been turning into an Earth-facing position and now looks like it could be threatening. Active region 3576 has already emitted a couple of low-class solar flares but could be poised for even more. An M5.1 solar flare was detected around region 3575 on the 7th of February as well. Updated imagery shows that an associated coronal mass ejection, or CME, was likely however, due to the location near the Sun’s south-west limb, it was directed mostly away from Earth. The solar flux index remained high this week, hitting 190 on the 6th before dropping to 188 on the 8th. Geomagnetically, the Sun has been behaving itself with a maximum Kp index of only three on Sunday the 4th. But all eyes will be on active region 3576 next week as it could upset the apple cart. Meanwhile, daylight maximum usable frequencies over a 3,000km path remain more than 28MHz, which is good for HF. Next week, NOAA predicts that the solar flux index may decline to be in the range of 160 to 170. Geomagnetic conditions are also predicted to be settled with a low Kp index. However, as we said earlier, that could all change if we have a violent solar flare and associated coronal mass ejection from region 3576 or any of the many other sunspots. And now the VHF and up propagation news from G3YLA and G4BAO Unsettled weather describes the pattern for the coming week, including some colder weather mixed in to provide snowfall for some areas, particularly in northern areas. This characteristic weather type will mean little chance of Tropo during the period. Other propagation modes of interest might be even harder to find unless you are thinking of rain scatter, which could be useful for a few suitably-equipped stations on the GHz bands. Other modes, such as meteor scatter or aurora, are also looking a bit thin. There is always the chance of some random activity, unlike Sporadic-E which is in its late winter lull that usually lasts until April for the 10 and 6m bands. For EME operators, Moon declination is negative and rising, going positive on Monday the 12th. So there will be higher peak Moon elevations and longer Moon windows throughout the week. Path losses were at their lowest at perigee on Saturday the 10th. 144MHz Sky noise is moderate to low. And that’s all from the propagation team this week.

The CQ Worldwide WPX RTTY Contest starts at 0000UTC on Saturday the 10th of February and ends at 2359UTC on Sunday the 11th of February. Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number.

Using CW and SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and serial number. Dutch stations send their province.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 1st of February 2024 We had another week of relatively calm geomagnetic conditions with a maximum Kp index of three. The solar flux index declined from 172 on the 24th to 135 on the 30th. Nevertheless, that is still enough to support propagation on the 10m band, with the maximum usable frequency over a 3,000km path generally being between 29 and 36MHz during daylight. Solar activity has been at low levels with only minor C-class flares and one M-class flare detected. Active region 3559 is now located behind the west limb of the Sun and out of direct view. New active region 3567 in the northeast quadrant is showing the most promise as it appears to be in a growth phase. There is currently a 25% chance of a moderate M-class flare, according to the latest NOAA and SWPC update. Earlier in the week, we had a period of moderate S2-level radiation storming. Proton levels streaming past Earth, following a solar flare early on Monday morning, increased but this has now declined. A minor coronal hole also became Earth-facing on the 2nd of February, so we may still expect some disruption today, Sunday the 4th. The 10m band is still romping along, with beacons along the eastern seaboard of the USA coming alive in the afternoon. This weekend, the 3rd and 4th, sees the 10-10 International Winter SSB Contest, so there should be plenty of stations to work on 28MHz. Next week, NOAA predicts that the solar flux index may rise again, perhaps to 150 today Sunday 4th, and up to 165 a week later. We may have unsettled geomagnetic conditions on the 5th and 6th, with the Kp index predicted to rise to three.   And now the VHF and up propagation news from G3YLA and G4BAO This week, ending the 4th of February, saw high pressure to the south of Britain and fronts over northern areas. For some stations in the southern half of the country, there could be useful Tropo conditions for the 432MHz Affiliated Societies Contest taking place today, the 4th. Unfortunately, the frontal activity over the north will move south on Tuesday to remove any chance of these better conditions lasting into the 144MHz UK Activity Contest on Tuesday the 6th of February. The period from mid-week onwards looks dominated by low pressure with rain or showers and generally flat VHF and UHF prospects unless you are set up for rain scatter. Other propagation modes like meteor scatter, aurora or Sporadic-E seem likely to remain in the background for the coming week. For EME operators, moon declination is negative and falling to a minimum on Tuesday the 6th. Path losses are also decreasing since their maximum at apogee on Monday the 29th. But with the low peak moon elevations, only eight degrees on Tuesday, moon windows will be short. 144MHz sky noise is moderate to very high all week going over 3100 Kelvin on Tuesday the 6th. Friday and Saturday see the moon and sun very close together, so Sun noise in antenna beamwidths will be an issue. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 28th January 2024

GB2RS News Sunday the 28th of January 2024 The news headlines: The RSGB election deadline is coming up RSGB Build a Radio workshop planned at Bletchley Park Registration for SOS Radio Week is open The deadline for nominations in the RSGB elections is next Wednesday, the 31st of January. If you would like to stand for the one elected Director role, or any of the eight Regional Representative vacancies, you will need to complete the nomination process by 2359UTC on Wednesday. Full details of the process are on the RSGB website at rsgb.org/election  The Society would encourage anyone with a passion for amateur radio, and a desire to support the amateur radio community, to look at the candidate information and consider stepping forward for one of these roles. You’ll find full information about the skills and experience needed in the candidate packs, and there is still time for an informal chat about the roles and responsibilities if you’d like one. But don’t delay as late applications won’t be accepted! As part of its British Science Week activities, the RSGB is organising two build-a-radio workshops at Bletchley Park on Sunday the 17th of March. Funded by the Radio Communications Foundation, these fun workshops are a great way for young people to try a practical amateur radio activity. The sessions are for youngsters aged 11 to 18 who will build their own VHF FM broadcast receiver using simple tools. The workshops cost £11 for the participant, and if you are an adult accompanying a participant who is aged 16 or under, you will receive free admission to Bletchley Park. These workshops are always very popular so book now if you know a youngster who would like to take part. Go to the Bletchley Park website at bletchleypark.org.uk then choose the What’s On option from the top right-hand menu. SOS Radio Week is an annual event that takes place throughout May to celebrate the work of the volunteers from the Royal National Lifeboat Institution, Independent Lifeboats and National Coastwatch Stations around the British Isles. Members of these organisations save many people who are in danger along, and around, the thousands of miles of coastline and further out to sea. This year is the 200th anniversary of the founding of the RNLI, so SOS Radio Week is being branded ‘SOS Radio Week 200’ for those operators who are supporting the RNLI during the event. Participants can operate from home, a public location, or a lifeboat or Coast watch station, with the appropriate authorisation from the station manager. A commemorative certificate will be available to all official stations that record their contacts on the website, together with awards for the top individual and club, or group, stations on each band from 160m to 70cm. Registration for individual and group operators is now open via sosradioweek.org.uk The RSGB has released a further three presentations from its 2023 Convention. In the first, Professor Simon Watts, G3XXH gives a fascinating presentation about VHF airborne radar and the design and performance of these early systems in World War II. The other two presentations focus on the World Radiosport Team Championship which the UK will be hosting in 2026. The WRTC is held every four years and is considered to be the Olympic Games of radio contesting. At the RSGB Convention, WRTC Chair Mark Haynes, M0DXR gave an overview of what is being planned and how people can get involved either as a spectator, volunteer, competitor or referee. John Warburton, G4IRN gave his perspective on what it is like to be a WRTC referee. The full WRTC planning team also gave an update recently on an RSGB Tonight@8 live webinar. You can see all of these presentations on the RSGB YouTube channel at youtube.com/theRSGB RadCom Basics aims to help newcomers to amateur radio develop their knowledge and experience. Others enjoy reading it as it helps remind them of things they have forgotten or practise a skill they have not used for a while. The January 2024 issue of RadCom Basics is now available. It contains articles that provide advice on getting started with Bunkers on the Air, working on the 160 and 80m bands, constructing a multi-band vertical antenna, and more. You can find RadCom Basics at rsgb.org/radcom-basics The latest issue of RadCom Plus, the online magazine for the more technically-minded radio amateur, was published this week. The first article, by Tom Alldread, VA7TA, is about how to make a protection filter for an SDR or VNA. Following this is a contribution from Sheldon Hutchison, N6JJA who discusses how to make an effective antenna noise canceller. You may recall the article by Andy, G0FVI in October’s RadCom which discussed the principles of antenna noise cancellation. Sheldon investigates exactly how the canceller should work, and his investigations have resulted in his superior design which you can construct for yourself. The third article, by Michael Toia, K3MT, is all about understanding the relationship between a train of square pulses and the harmonic content of its frequency spectrum, not with complicated mathematics, but by using an entirely diagrammatic approach. Those less familiar with mathematics might especially find this article helpful. This issue of RadCom Plus ends with Andy Nehan, G4HUE discussing the design of analogue power supplies. Members of the RSGB can access RadCom Plus via rsgb.org/radcom-plus  And now for details of rallies and events The Lincoln Short Wave Club Winter Radio Rally is taking place today, the 28th, at The Festival Hall, Caistor Road, Market Rasen, LN8 3HT.

The British Amateur Radio Teledata Group RTTY Sprint started at 1200UTC on Saturday the 27th and ends at 1200UTC today, the 28th. Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is serial number. On Wednesday the 31st, the UK and Ireland Contest Club 80m Contest runs from 2000 to 2100UTC. Using CW on the 80m band, the exchange is your six-character locator. The UK Six Metre Group Winter Marathon began on Friday the 1st of December 2023. The contest will run until the 31st of January 2024. Using all modes on the 6m band, the exchange is signal report and locator. On Sunday the 4th of February, the 432MHz Affiliated Societies Contest runs from 0900 to 1300UTC. Using all modes on the 70cm band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of January 2024 We dodged a bullet last week when a coronal mass ejection, or CME, was predicted to be heading our way. In the end, it came to nothing. The CME observed on the 20th of January was expected to pass Earth and deliver possible G2 storm conditions. But a solar wind enhancement, possibly associated with the plasma cloud passing near Earth, saw the Kp index rise to only 3.67 on Wednesday the 24th. The many solar flares, and associated coronal mass ejections, over the past few days make it difficult to give a reliable geomagnetic forecast. Over the past seven days, there have been more than 60 C-class and 18 M-class flares, typical for this point in the solar cycle. Sunspot-wise, the solar flux index has remained high, being more than 170 all week. Critical frequencies have often exceeded 11MHz during daylight hours, which means the 30m band, as well as the 40m band, should be open around the UK. However, nighttime critical frequencies have fallen below 4MHz, meaning that even the 80m band struggles at times. We mentioned last week that the NCDXF beacon VK6RBP in Australia had been heard on 28.200MHz. If you’ve copied VK6RBP you might be interested in trying for some other lower-power Australian beacons on the 10m band. Try listening for the 8W VK4LA/B on 28.206MHz in Brisbane, or perhaps the 10W VK4RST, which is 550km north-west of Brisbane, on 28.266MHz. Next week, NOAA predicts the solar flux index will be in the range of 155 to 175. Geomagnetic conditions are forecast to be quiet, other than on the 29th of January when the Kp index is predicted to rise to three. But, as always, keep an eye on solarham.net for a near real-time report. And now the VHF and up propagation news from G3YLA and G4BAO Today, the 28th, sees the UK recovering from the two named storms and just getting settled into moving high pressure across northern France, with a second centre crossing central Britain early next week. This offers a chance of Tropo, especially in the south, while fronts continue to affect Scotland. After the middle of the coming week, a more unsettled pattern returns with fronts crossing the country, which might bring some rain scatter for the GHz bands. But, in general, the picture remains unsettled into the end of the week and doesn’t look too exciting for the 432MHz Affiliated Societies Contest on Sunday the 4th of February. Other propagation modes that are worth considering are all relatively low-key in the transition into February. This means that meteor scatter is best looked for in the early pre-dawn period when random meteor activity peaks. The other chance might be aurora, and this is simply about checking the behaviour of the Kp index, which measures the disturbance of the earth’s magnetic field by solar activity. Kp indices higher than six are a good sign for aurora.  It looks like we are in a quiet period for Sporadic-E propagation. For EME operators, Moon declination is positive and falling, going negative again on the 30th. Path losses reach their maximum at apogee on Monday the 29th, then start to fall again. 144MHz sky noise is low all week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 21st January 2024

GB2RS News Sunday the 21st of January 2024 The news headlines: British Science Week is approaching Updates on the RSGB’s Strategic Priorities RSGB election deadline reminder   This year’s British Science Week runs from the 8th to the 17th of March with the theme of Time. This event is a fantastic opportunity to raise awareness of amateur radio in your local area. The RSGB has some great activity ideas you could try at your local school, Scout or Guiding group or local youth club. Go to the web page at rsgb.org/bsw and click on the activity titles to find everything you need to know to be able to run that activity. Several radio clubs from across the UK have already planned outreach activities for British Science Week and the RSGB hopes its resources will inspire you to get involved too! RSGB volunteer John Hislop, G7OHO has provided these ideas but the Society would love to add other activities to enthuse young people about wireless communication. If you have an amateur radio activity on the theme of Time that you’d like to share, or if you’d like to get involved but aren’t sure how to start, please direct enquiries to the RSGB British Science Week contact, Ian Neal, M0KEO. Ian’s contact details will soon be available at rsgb.org/bsw At the Discussion with the Board session at the RSGB 2023 Convention, the RSGB President, John McCullagh, GI4BWM confirmed that the Board would keep members updated regularly on progress with the new strategic priorities. Two updates have now appeared in the January and February issues of RadCom and they are also available to read on the RSGB website. These updates highlight some important activities and achievements as well as new plans, so the Society encourages every member to take the time to read them. Go to rsgb.org/strategy and choose the ‘Strategy priorities updates’ option from the righthand list. Further updates are being prepared so do check back regularly or look out for them in each RadCom. You can also watch the Discussion with the Board Convention session on the RSGB’s YouTube channel at youtube.com/theRSGB The deadline for applications for the one elected RSGB Board Director position and eight Regional Representative roles is Wednesday the 31st of January. Amateur radio needs a strong and active national society so don’t leave it to everyone else, step forward for one of these roles and play your part in the future of the RSGB. You'll find guidance and candidate forms on the RSGB elections web page at rsgb.org/election as well as contact details if you want an informal chat before standing for election. A reminder that the RSGB is looking for four licensed radio amateurs to help raise the profile of wireless communication amongst young people across the UK. We have had a good response, but we’d still like to hear from prospective volunteers in Northern Ireland and Wales. These volunteer Youth Country Representatives will represent the RSGB at externally organised events and will plan and deliver outreach activities. If you have plenty of ideas, a passion for getting young people involved in amateur radio and experience of running small-scale events, we would be very keen to hear from you. The deadline is Friday the 16th of February. For full details, see rsgb.org/volunteers and for an informal discussion, please email RSGB Board Director, Ben Lloyd, GW4BML at [email protected] GB2RS began broadcasting via the Es’hail-2 amateur satellite in May 2021. Every Sunday at 0800UTC you can hear the latest RSGB news on the dedicated narrow-band QO-100 transponder frequency of 10489.855MHz. This has proved so popular that, by the kind permission of AMSAT-DL, from the 4th of February 2024 we’re introducing a second reading at 2100UTC. This will suit our international audience in the western lobe of the footprint. The existing team of three Newsreaders is looking for another volunteer to join them. If you are an RSGB member with a good QO-100 facility and would be interested in broadcasting the news, please contact the GB2RS Manager, Steve, G4HPE at [email protected] for further details. During February, the RSGB’s Photo Friday focus on social media is all about clubs. If you’d like your club to be included, let the RSGB comms team know what you've been up to and who's been involved and share all the brilliant things you've been doing. Email [email protected] by the 31st of January with a brief summary of the activity and some photos, and please make sure that everyone in the photo is happy to have their face on social media! Chris Deacon, G4IFX has been awarded a PhD from the University of Bath after completing research on propagation. His thesis was entitled: “Radio propagation through ionospheric Sporadic-E”. This part-time work over many years involved looking at Sporadic-E on the 6m band, including making novel measurements of signal amplitude, phase, derived Doppler, polarisation and potential time delay to discover the nature of sporadic-E propagation at VHF frequencies. The RSGB Propagation Studies Committee congratulates Chris on this fantastic achievement. You can find out more by searching for Chris’ name on the University of Bath research portal at researchportal.bath.ac.uk  Chris has done a number of presentations about propagation at RSGB Conventions over the years, which you can see on the RSGB YouTube channel at youtube.com/theRSGB And now for details of rallies and events The Lincoln Short Wave Club Winter Radio Rally will take place on Sunday the 28th of January at The Festival Hall, Caistor Road, Market Rasen, LN8 3HT.

Using all modes on the 13cm band, the exchange is signal report, serial number and locator. The CQ 160m DX Contest starts at 2200UTC on Friday the 26th and ends at 2200UTC on Sunday the 28th. Using CW on the 160m band, the exchange is signal report and CQ zone. American stations send their state and Canadian stations send their province. The British Amateur Radio Teledata Group RTTY Sprint starts at 1200UTC on Saturday the 27th and ends at 1200UTC on Sunday the 28th. Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is a serial number. The UK Six Metre Group Winter Marathon began on Friday the 1st of December 2023. The contest will run until the 31st of January 2024. Using all modes on the 6m band, the exchange is signal report and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 18th of January 2024 We had yet another week with good solar conditions which, at this point in the cycle, is good news. The solar flux index remained in the 170s to 180s range and the Sun is currently peppered with spots. The Kp index never got above 3.33 and that was only for one three-hour period on January the 16th. We were also lucky with solar flares in that we only had minor C-class flares to contend with. An eruption was observed beyond the west limb on January 14th. The event generated a fast-moving coronal mass ejection or CME, but it was directed away from our planet. Daytime MUFs over 3,000km remain high at more than 28MHz. At night this reduces to around 6.9 to 9.5MHz, meaning only the 40m band is mainly open to DX, if at all. HF-wise, this is the best time for low-band DXing, such as 40m band contacts with New Zealand around sunrise, and overnight QSOs on the 80m band with the USA. Other DX being worked by members of CDXC includes XU7AKU in Cambodia on 40m CW in the early evening; V31XX in Belize, VP9KF in Bermuda, on 30m CW around 1000UTC; and E20AX in Thailand on 40m CW around 0930UTC. Next week, NOAA predicts that the solar flux index may remain in the 160 to 170 range with a maximum Kp index of 2. As always, take that Kp prediction with a pinch of salt as a single Earth-facing coronal mass ejection could send it sky-high with an accompanying lowering of the MUF and generally poor conditions. And now the VHF and up propagation news from G3YLA and G4BAO The main theme of the VHF and up propagation options is that we have three distinct phases coming up. The first phase is set to end today, the 21st. This will be the final blast of the cold northerly wind, which may produce some rain scatter near coasts from snow showers. It is probably not especially useful for Tropo, even inland, except perhaps for local overnight temporary short-distance enhancements due to surface cooling and night frosts. Phase two is the transition to very unsettled, wet and windy weather, which starts to arrive during this weekend, ending the 21st, and generally sets the pattern for much of the coming week. Maybe it will be a rain scatter option for the GHz bands, but the main radio consideration will be wind potentially damaging antennas, particularly in the south. Phase three will be the introduction of a weak ridge of high pressure over southern Britain in the second half of the coming week and the following weekend. This could bring some more productive Tropo to southern parts of the UK, especially into the last weekend of the month. Other propagation modes are available but don’t seem to be elevated beyond chance occurrences for meteor scatter or aurora. There is a vanishingly small chance of Sporadic-E, as we are in the minimum period for this sort of propagation until after Easter. For EME operators, Moon declination is positive and rising, reaching a maximum on the 23rd. Path losses increase all week until apogee on Monday the 29th. 144MHz sky noise is low to moderate this coming week. And that’s all from the propagation team this week.

On Saturday the 20th, the Affiliated Societies 80 and 40m SSB Contest runs from 1300 to 1700UTC. Using SSB only on the 80 and 40m bands, the exchange is signal report and serial number. The UK Six Metre Group Winter Marathon began on Friday the 1st of December 2023. The contest will run until the 31st of January 2024. Using all modes on the 6m band, the exchange is signal report and locator.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of January 2024 We couldn't have asked for better solar conditions last week. We had a low Kp index that never got any higher than 2.67, and a solar flux index that started the week at 167 and then rose to 186 by Wednesday. So, at first glance, this looks like ideal conditions for HF. However, we are in the middle of winter and therefore the ionosphere is not at its best. The low bands are also being affected by the higher solar flux and, on the whole, the 14MHz band and above are closing as the night draws in. Daytime critical frequencies remain around 9 to 10MHz, so the 40m band should remain useful for inter-UK work. Nighttime critical frequencies are currently falling to 3.5 to 4.5MHz, which means the 40m band is only open to long skip, if at all.   The critical frequency is the highest that still returns a signal from the ionosphere if sent straight up, and is a good guide as to which bands are open to near vertical incidence skywave or NVIS signals around the UK. On the brighter side, 14MHz has been showing signs of DX. The VK6RBP beacon has been heard on 14.100MHz in the afternoon via the short path and 28.200MHz in the morning via the long path. The 12m band has shown international beacons RR90 in Siberia, OH2B in Finland, LU4AA in Argentina and YV5B in Venezuela, on 24.930MHz in the morning. While the 10m band also highlighted YV5B in Venezuela during mid-morning. Not a massive catch, but better than we were getting two years ago! For the coming week, NOAA predicts that the solar flux index may fall into the range of 150 to 165. Geomagnetic conditions are predicted to remain settled with a maximum Kp index of 2. As always, this could easily change if we have a coronal mass ejection, so keep an eye on solarham.net for near real-time solar conditions.   And now the VHF and up propagation news from G3YLA and G4BAO The area of high pressure has been working well for some parts of the country, with Tropo conditions lasting into the start of this weekend, but as a cold front moves South on Saturday the 13th, all will change as the high becomes displaced to the Atlantic. Therefore, there is no significant Tropo for the coming week, but there may be some rain scatter from showers, especially around the coasts. We seem to have passed the period of unusual winter Sporadic-E propagation without much evidence of activity so that just leaves meteor scatter. After the Quadrantids last week, we entered a period of low meteor shower activity, leaving just random meteors until the next major shower, the Lyrids in April. For random meteor scatter, the pre-dawn period works best. The solar conditions can still be instrumental in producing extra propagation treats with chance aurora. Probably the best operating policy is to monitor the geomagnetic Kp-index with high values greater than 6 being a good sign for VHF. For EME operators, this week starts with very low Moon declination, low peak Moon elevation and short Moon windows, but declination is rising and goes positive again on Tuesday. Path losses are still low and reached minimum at perigee on Saturday the 13th. 144MHz sky noise is low for all of the coming week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 7th January 2024

GB2RS News Sunday the 7th of January 2024 The news headlines: RSGB Regional Team vacancies RSGB volunteer interviewed by the BBC RSGB National Radio Centre seeks to expand its team of volunteers   The news team and all the staff at RSGB HQ would like to wish our newsreaders, listeners and online readers a very happy New Year. We would like to remind everyone that we always welcome your news, by email, to [email protected] and the deadline is 10 am sharp on Thursday mornings. The GB2RS script is usually uploaded to the RSGB website by 4.30 pm each Friday afternoon. Are you interested in supporting your local radio amateurs and promoting amateur radio where you live? The RSGB Regional Team has eight Regional Representative vacancies across the UK where you could make a difference. Last year, Regional Reps got involved in a variety of activities including British Science Week and YOTA Month to help spread the word about amateur radio in their regions. If you have the passion to do this, go to the RSGB website at rsgb.org/election to find out how to apply. The deadline for applications is the 31st of January. It was great to hear RSGB volunteer Peter Marcham, G3YXZ on BBC Radio Oxford on New Year's Day. Peter volunteers at the RSGB National Radio Centre, as well as being a tour guide at Bletchley Park. He spoke to radio presenter Sophie Law about his volunteering after sending the words "Bletchley Park Guide" to a three-word, text-in feature on why listeners were up early on New Year's Day. Search for Sophie Law on BBC Sounds, choose the New Year’s Day programme and listen from 2 hours, 11 minutes, and 25 seconds. There is so much happening at the RSGB National Radio Centre that it needs to expand its team of volunteers! If you can volunteer on a Friday or Saturday, you will be particularly welcome. The NRC has a fabulous set-up, and full training on using the GB3RS radio station will be given. You should enjoy meeting people and be able to volunteer for one or two days per month as part of a friendly and dedicated team. NRC volunteers also enjoy numerous benefits associated with volunteering at Bletchley Park. For more information, please email NRC Coordinator Martyn Baker, G0GMB via [email protected] We have received the sad news that both Mick Senior, G4EFO and Martyn Vincent, G3UKV have become Silent Keys recently. Mick was a former Regional Representative for Region 10, and the keeper of a number of local repeaters. Martyn was the District Representative for Shropshire, North Worcestershire and West Birmingham. Previously, he volunteered for the RSGB as the Regional Representative for Region 5 and as a member of the Nominations Committee. He was also a very well-respected member of the microwave and contesting communities. Our thoughts are with their families at this difficult time. This year marks 150 years since the birth of Guglielmo Marconi in 1874. The Cornish Radio Amateur Club will be organising International Marconi Day this year on the 27th of April. For more information and updates, visit the GB4IMD Facebook page. The RSGB’s RadCom team is looking for authors to contribute to the magazine.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 4th of January 2024 Welcome to the first HF propagation report of 2024 – it looks like it will be business as usual! A massive X5-class solar flare occurred on the 31st of December. Luckily, this happened at 2155UTC so didn’t affect the ionosphere over the UK. But it did launch a large coronal mass ejection, which was forecast to possibly hit the Earth on the 2nd of January. It looks like it largely missed us, although low-energy proton levels streaming past Earth continued to rise and were at the minor S1 radiation storm threshold on Wednesday the 3rd. Had active region 3536 been directly facing Earth when the flare was observed, a stronger proton event and geomagnetic storm would have been very likely. Only minor HF signal degradation through the polar zones should be expected because of the minor S1 storm. So, it looks like we dodged the bullet again, but this is a warning that there could be more to come. Otherwise, the solar flux index declined to the 140s over the Christmas period, although it looks like it may increase over the coming week. NOAA predicts it could be in the range of 150 to 160 next week, with a maximum Kp index of 3 on Monday the 8th, or Tuesday the 9th. However, this could soon change if we have another solar flare and subsequent coronal mass ejection, which could see the Kp index rise two days later. So, make the most of HF when the Kp index is low! Otherwise, the winter period is when the low bands, from 160 to 40m, come into their own. While solar maximum is not the best time for low-band propagation, there will still be plenty of DX to be worked. Generally speaking, winter is a good time for east-west paths on HF too. Taking a closer look at 40 metres, the band should open for DX in an easterly direction during the late afternoon and towards the south at sunset. Paths during the afternoon may also include West Coast USA in mid-winter. Relatively local contacts should be possible during the day, as the critical frequency remains above 7MHz during daylight. And now the VHF and up propagation news from G3YLA and G4BAO A new year brings a change of weather type and, after some residual rainfall events at the tail end of the previous week, we should be seeing a marked improvement in the weather as high-pressure returns fairly generally across the country by this first weekend of January, ending today, the 7th. This will remain near, or very close by, for much of the coming week and into the following weekend. It is good news for Tropo, initially over the North Sea towards southern Scandinavia and the Baltic region, but will probably change to favour the western side of Britain in the second half of the week. This is nice timing to coincide with the 70cm band RSGB contests during the week on Tuesday the 9th and Wednesday the 10th of January. Up until the middle of the month, we should be alert to rare mid-winter sporadic-E propagation. With a very contorted jet stream pattern during the whole period, the chances are better than average. This is another piece of good timing for the 50MHz UK Activity Contest on Thursday the 11th. We were going through the Quadrantids meteor shower as this report was being written, so this may provide a little boost to meteor scatter into some of the coming week. Rain scatter will be a rapidly diminishing option during the period as high pressure builds next week. The solar conditions continue to produce elevated Kp index events. So, again, check for auroral openings although, generally, aurora is usually better towards the Spring. For EME, this week we see a negative Moon declination, falling to a minimum by Wednesday. So, Moon windows will be short and peak Moon elevation will be low. Path losses are also low, but we are still over a week away from perigee, the closest approach of the Moon to the Earth. 144MHz sky noise increases all week culminating in the Sun and Moon being close in the sky on the 11th. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 24th December 2023

GB2RS News Sunday the 24th of December 2023 The news headlines: Examinations and Syllabus Review Group to update syllabus The RSGB election process is underway Volunteer Youth Country Representatives sought   Season’s greetings to all our listeners! Today’s GB2RS news script will be the final one of 2023. Today’s news reading is optional, as the RSGB appreciates that not all newsreaders will be available, but the script will be on the RGSB website so all can see it. We’d like to take this opportunity to thank all the newsreaders, who read the news on a variety of platforms, for their service to their fellow amateurs throughout the year. We’d also like to remind amateurs that there has been a long-standing convention to listen for news broadcasts on Sundays before transmitting, to allow news reading to go ahead without interference. Thank you to all those who listen on Sunday mornings, and the other times that the news is read, to those who call in afterwards to speak to the newsreaders, and to everyone who listens via various platforms. Please note, there will be no script prepared for broadcast on Sunday the 31st of December 2023 due to RSGB HQ being closed from 4.30 pm on Friday the 22nd of December until 8.30 am on Tuesday the 2nd of January 2024. Newsreaders may, of course, choose to run a net at their normal transmission time, but under their own callsign only. Following its consultation on proposed changes to the amateur radio licence, Ofcom has recently published the “General notice of proposal to vary amateur radio licences”. The timescale for putting the licence changes into effect means that the Examinations and Syllabus Review Group has been working on the revised syllabus, version 1.6, in parallel with the Ofcom consultation. To read the full explanation, and see the draft sections, go to the RSGB website at rsgb.org/training and choose the ‘Trainer Information’ link in the righthand menu. The RSGB election process is underway and the closing date for RSGB Nominated Directors is Wednesday the 3rd of January. In being a Director, you are responsible for taking strategic decisions that steer the direction of the Society and provide leadership and motivation to implement its strategy. If you have the right skills and attributes that you think can help the Society develop for the future, then please get in touch. Contact the Nominations Committee Chair, Bob Beebe, GU4YOX via [email protected]   On the RSGB website there is information about the Elected Director and Regional Representative roles available and the process for standing for those roles. You can also read an important statement from Don Beattie G3BJ, former RSGB President and IARU Region 1 Past-President, in which he outlines what he thinks are the necessary skills for Board Directors and encourages people to play their part in the future of the Society. Go to the RSGB website at rsgb.org/election to find out more. A reminder now that the RSGB is looking for four licensed radio amateurs to help raise the profile of wireless communication amongst young people. Initially, we’re looking for RSGB members based in England, Northern Ireland, Scotland and Wales to engage young people in the hobby. These volunteer Youth Country Representatives will represent the RSGB at externally organised events and will plan and deliver outreach activities. If you have plenty of ideas, a passion for getting young people involved in amateur radio and experience of running small-scale events, we would be very keen to hear from you. For full details of these roles, see rsgb.org/volunteers and for an informal discussion, please email RSGB Board Director, Ben Lloyd, GW4BML at: [email protected] If you live in Region 11 you could support your local amateur radio community by becoming an RSGB District Representative. DR111 covers Cornwall and the Scillies, whilst DR114 focuses on Dorset. If you would like to find out more, please contact the Region 11 Regional Representative, Andrew Jenner, G7KNA. There are also District Representative vacancies in Region 3 and Region 10 – find out more on the RSGB website at rsgb.org/volunteers Two more RSGB Convention presentations will be published on YouTube over the Christmas holidays. In the first, Nobby Styles, G0VJG describes the challenging and hazardous DXpedition to Europe’s rarest IOTA location, Rockall Island. The second presentation, by David Lauder, G0SNO, outlines the RSGB EMC Committee investigations into sources of RF electrical interference from recent developments in electronic equipment, including electric vehicle charging. Subscribe to the RSGB YouTube channel to be notified when these presentations are available and get ready for some great Christmas viewing! Go to youtube.com/theRSGB to subscribe.

Using all modes on the 4m band, the exchange is signal report, serial number and locator. On Thursday the 28th, the 144MHz Christmas Contest will take place between 1400 and 1600UTC. Using all modes on the 2m band, the exchange is signal report, serial number and locator. On Friday the 29th, the 432MHz Christmas Contest will take place between 1400 and 1600UTC. Using all modes on the 70cm band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 21st of December 2023 We filed last week’s GB2RS propagation report and, shortly after, we had the biggest X-ray solar flare event this cycle! This just shows how hard it is to predict solar activity and why long-term HF predictions are problematic. Anyway, back to the solar flare which occurred at 1702UTC on the 14th of December. This was an X2.8 event that was also responsible for a coronal mass ejection. Luckily, the Sun had already set in the UK but if you were working the USA, Caribbean or South America on HF, you may have found the path suddenly disrupted. If that did happen to you, please let us know. The full halo coronal mass ejection, or CME, that followed headed mostly to the west, although a glancing blow was predicted to hit us on the 15th or 16th of December. It eventually hit late on the 17th of December, pushing the Kp index to six on the morning of the 18th of December. HF conditions remained fairly unsettled after that. Next week, NOAA predicts that the solar flux index will be in the 140 to 150 range again and that the Kp index will be no more than two. However, that geomagnetic prediction may be wishful thinking. There are a lot of sunspots at the moment and active region 3529 may be a strong candidate for flare and CME action over the coming week. So, our message is: work the DX when you can and don’t ignore the lower bands, such as 40, 80 and 160 metres, which may offer some good DX at night in the middle of winter. And now the VHF and up propagation news from G3YLA and G4BAO The weather pattern over the Christmas period is set up as a teaser between very mild, and cold enough for some wintry weather. However, it probably won’t be cold enough – except in the north – to get too excited before the 25th. To set the scene and give you a chance to ‘roll your own forecasts’ in view of the long lead time for this forecast, the atmosphere is part way through its normal transition from summer-time Atlantic jet streams over Iceland to winter jet streams over the Mediterranean.  We are currently in the middle, and this puts the main jet stream path across the British Isles. It will produce alternating periods of mild and cold weather – very difficult to pin down even a few days ahead, let alone into the New Year! What we can get from this, in terms of propagation, is a good chance of the meandering jet stream being able to invoke a mid-winter Sporadic-E event for some of us. However, the times are less predictable than in the summer, so just keep a listen out on the 10m and 6m bands for activity, it would be a shame to miss any. Tropo has done well over the last weekend, so a large high to the south of the UK, over the continent, is worth looking out for especially paths south to Iberia or east to the Baltic. Lastly, look out for the lesser modes of scatter from rain or meteors, which will continue to be a random option, as well as the potential for aurora. For EME operators, Moon declination is positive and rising, reaching a maximum on Boxing Day. Path losses are rising to a maximum on New Year’s Day. 144MHz sky noise is moderate all week. Finally, a big thank you from the propagation team for the 'fine business' effort you all put into getting on the bands to explore and report these exciting propagation modes… Merry Christmas! And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 17th December 2023

GB2RS News Sunday the 17th of December 2023 The news headlines: Ofcom document on changes to amateur radio licensing released YOTA month continues WRC-23 concludes Earlier this week, Ofcom released a document titled “Updating the Amateur Radio Licensing Framework”. The document states that amateur radio licences will be changing in 2024 and provides details of the changes that are planned. These include adjustments to the overall licensing framework and rules in a number of areas including callsigns, technical parameters, licence format, terms and conditions. To read the document in full, as well as a range of associated documents and resources generated by the RSGB and Ofcom, visit rsgb.org/licence-review Youngsters on the Air month is well underway with some great activity from a range of schools, universities and radio societies. If you’d like to get involved, you can listen out for special callsign GB23YOTA and make these young operators feel welcome on the air. Today, the callsign is being operated between 9 am and 6 pm under the supervision of RSGB Board Director, Ben Lloyd, GW4BML. Young members of the Hereford Amateur Radio Society, and other local youngsters, will be getting on the air. Later this week, on Thursday the 21st of December between 6 pm and midnight, Ben will also be helping a fully licensed young radio amateur activate a SOTA summit. They will be working the 160m and 80m bands with the YOTA callsign. On Saturday the 23rd of December, Tommy M7OMY, supervised by M0BOY, will be back on the air for the duration of the day and night. There is still time to get involved with Youngsters on the Air month – just email Jamie, M0SDV at [email protected] to book a slot or ask for further information. Following four weeks of deliberations, the 2023 World Radiocommunication Conference concluded in Dubai on Friday the 15th of December with the signing of the ‘Provisional Final Acts’ and a closing ceremony. The numerous changes don’t formally take effect until the 1st of January 2025 and preparations are already underway to agree the agenda for future WRC events. The RSGB’s special focus pages have the final news report and photos. To view these, visit rsgb.org/wrc-23  The results will be reviewed by the Spectrum Forum after the Christmas break, alongside IARU and domestic changes. The UK Meteor Beacon project is now in its second phase, and both phases have been supported by the RSGB Legacy Fund. At the RSGB 2023 Convention, Brian Coleman, G4NNS outlined the plan for the second phase. A network of receivers will be developed, streaming their data via a central server for detailed study of individual meteor events. This is a cooperation between the ‘worlds’ of amateur radio and astronomy. You can now watch Brian’s presentation on the RSGB YouTube channel at youtube.com/theRSGB  The RSGB Legacy Fund supports a wide range of amateur radio projects. You can find out more and download an application form on the RSGB website at rsgb.org/legacy The RSGB election process has begun and there are eleven roles to fill. These include eight Regional Representatives covering a wide range of regions, as well as an elected Director and two Nominated Directors. Bob Beebe, GU4YOX is the new Chair of the Nominations Committee and he is keen to see people volunteer. He says that being a Director of the RSGB is a great opportunity to contribute to the future direction of the Society and the RSGB needs the best people to come forward to play their part. If you don’t feel you can volunteer, do you know someone who would make a good Director? Do you know someone committed to amateur radio, in touch with the leading thinking in amateur radio today, and capable of contributing to the Society’s work in a team environment? If so, ask them to stand for election or as a Nominated Director. Find out more about the RSGB election process, and all the available roles, on the RSGB website at rsgb.org/election Following feedback from the amateur radio community, the RSGB’s Learning Team is launching a revised Discovery Scheme in the New Year. This will be a revamp of the Individual Scheme from the Beyond Exams initiative and consists of three levels of participation. The ‘Explorer’ level is aimed at newcomers to amateur radio and will run from January to March 2024. The ‘Adventurer’ level, which will run from April to June 2024, is targeted at those who have been involved with amateur radio for a while and wish to progress. Requiring more significant experience, the ‘Master’ level will run from July to December 2024. For more information, contact Beyond Exams Coordinator Mark Burrows, 2E0SBM​ via [email protected] As the 2023 year draws to a close, we’d like to take the opportunity to thank all the newsreaders who read the RSGB news on a variety of platforms for their service to their fellow amateurs throughout the year. We respectfully ask amateurs to check carefully before using 145.525MHz on a Sunday as there are many GB2RS broadcasts throughout the day on this frequency. Thank you to all those who listen on Sunday mornings, and the other times that the news is read, to those who call in afterwards to speak to the newsreaders, and to everyone who listens via various other platforms. RSGB HQ will be closed for Christmas and New Year from 4.30 pm on Friday the 22nd of December until 8.30 am on Tuesday the 2nd of January 2024. Next Sunday, the 24th of December, the GB2RS News script will be prepared as usual and read at the discretion of individual news readers. There will be no GB2RS broadcast on Sunday the 31st of December 2023 but many newsreaders will be holding informal nets in their usual broadcasting slots. During the holidays, if you need information about amateur radio, exams or RadCom you’ll find lots of pages on the RSGB website at rsgb.org The RSGB National Radio Centre at Bletchley Park will be closed on Christmas Eve, Christmas Day, Boxing Day and New Year’s Day. There will be reduced hours on New Year’s Eve when the Centre will be closing at 2 pm. Following the seasonal closures, the RSGB National Radio Centre will also be closed for essential maintenance works between the 2nd and 5th of January 2024. Outside of these times, volunteers look forward to welcoming visitors as usual. Remember that RSGB Members can download a free entry voucher for Bletchley Park from the RSGB website at rsgb.org/bpvoucher GB2RS News on the Isle of Man is delivered by a team of four Newsreaders and is widely heard thanks to the extensive GB3IM UHF repeater network.

He operates all modes on the HF and 6m bands and via QO-100. QSL via M0OXO's OQRS and Logbook of the World. Gab, HB9TSW has been active as Z68BG from the Slatina Air Base in Kosovo since the 5th of December. He is operating CW only in his spare time until the 19th of December. QSL via Logbook of the World, eQSL, or via his home call. Now the contest news On Tuesday the 19th, the 1.3GHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes on the 23cm band, the exchange is signal report, serial number and locator. On Thursday the 21st of December, the 70MHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of December 2023 We had a fairly settled time last week with only the solar wind and some solar flare activity to contend with. Sunspot region 3514 produced a moderately strong M5.8 solar flare on the 14th of December. This event was responsible for a coronal mass ejection, or CME, but that was directed to the west and missed the Earth. The problem with the solar wind is that its Bz has mostly been pointing south, which means it more easily couples with the Earth’s magnetic field allowing solar plasma to flood in. The result was that the Kp index mostly remained high, with the index hitting three or four across the midweek period. While not excessive, this has affected HF to an extent, although the daytime MUF over 3,000km has remained above 28MHz on most days. What you may find is that the higher bands are now closed until later in the morning and that they close earlier in the afternoon as well. This is partly due to the time of year and partly due to the lower solar flux index we are experiencing. The solar flux index improved slightly over the past week, ending at 135 on Thursday, having been in the 120s earlier. Next week NOAA predicts that the solar flux index will be in the range of 125 to 140. It is predicting unsettled geomagnetic conditions from the 16th to the 19th of December, with a maximum Kp index of five. Now for a propagation forecast. Santa’s broadcasting arm, Santa Radio OF9X, is active again from near the Arctic Circle on all amateur radio bands, using CW, SSB and FT8, until the end of the year. The activity is organised by the Radio Club of Pusula, OH9W and Radio Arcala, OH8X. Keep an eye on DXSummit.fi to find out where they are operating. So far, they have been spotted on the 160, 40, 20, 12 and 10m bands. The Proppy prediction chart shows that anywhere between 10MHz and 28MHz is fair game during daylight, while 7MHz and below will work better at night. And now the VHF and up propagation news from G3YLA and G4BAO As expected, the return of a significant region of high pressure developing over the continent as this week ends will bring some enhanced Tropo conditions from the southern UK into the continent and across Biscay to northern Spain. It is also possible that the traditionally preferred policy of beaming around the edge of a high for DX paths will make looking east into northern Germany, Poland and the Baltic a fair prospect, but only until around Tuesday the 19th when a cold front moves south and breaks the path. This is a pity since it will be before Tuesday’s 1.3GHz Contest and Thursday’s 70MHz UK Activity Contest, which look like missing the best conditions. The second half of the coming week will be dominated by low pressure to the north of Britain and a series of fronts and showery troughs driving south, bringing much colder air with a risk of wintry weather. It will also become very windy at times. This removes Tropo from the picture, but rain scatter may be worth considering, although the shower echo regions will be moving briskly. Use online rain radar displays to help you. The other modes of meteor scatter and aurora are worth leaving on the list with the remains of the December Geminids still with us. Don’t forget that out-of-season Sporadic-E propagation often appears in the period from mid-December to mid-January, so check the 10 and 6m bands periodically for activity. For EME operators, Moon declination is negative but rising, going positive on Wednesday the 20th. Path losses are at a minimum at perigee, the Moon’s closest point – this was on Saturday the 16th. 144MHz sky noise is low all week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 10th December 2023

GB2RS News Sunday the 10th of December 2023 The news headlines: 23cm recommendation approved at WRC-23 RSGB Examinations Standards Committee report published RSGB Elections process begins   The third week of the WRC-23 World Radiocommunication Conference has seen the approval of a new footnote to the 23cm amateur band at 1240 to 1300MHz under Agenda Item 9.1-b. This draws attention to the recently released ITU-R Recommendation 2164 that provides guidance to avoid interference to radio navigation satellite services, or RNSS, such as Galileo. This is a major landmark after four years of hard work which started after WRC-19 and now lays out the basis for guidance and next steps. IARU President Tim Ellam, VE6SH said that the addition of a footnote that provides guidance to administrations in the event of interference to the RNSS is a good regulatory outcome for amateurs and the primary users of this band. You can read more on this story at tinyurl.com/RecRNSS  The IARU team continues its work on other WRC issues including the development of agendas for future conferences. The RSGB special focus page provides regular updates and additional detail. You can find the page at rsgb.org/wrc-23  The RSGB Examinations Standards Committee has published its annual report, covering the operation of the amateur radio exams during the calendar year of 2022.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 7th of December 2023 We dodged a bullet last week as a high-speed solar wind stream from a coronal hole sped past the Earth. Although the wind speed was often in excess of 600 kilometres per second, its Bz, or magnetic field, was pointing north. The net result was that most of this passed harmlessly away from Earth and the Kp index remained around three. Meanwhile, the solar flux index declined to 130 by Thursday, which is quite a difference from the 194 we had on the 23rd of November. Solar activity last week reached moderate levels thanks to multiple low-level M-class solar flares detected around active region 3513 in the northeast quadrant. This region also produced frequent C-class flares. Daytime MUFs over a 3,000km path mostly remained over 28MHz, while nighttime MUFs over a similar path length remained around 10MHz. As we head towards mid-winter, we may expect these nighttime MUFs to drop, with the result that the 80m band closes down for short-skip early on in the evening – the curse of the inter-UK 80m Club Championship contests! However, the 80m band may still be open over long distances and we are now entering the best time of year for low-band DXing. Keep an eye on the top end of the 80m band, around sunrise, for transatlantic signals. Next week NOAA predicts that the solar flux index may recover a little and be in the range of 130 to 150. Geomagnetic conditions will depend upon coronal mass ejections but are predicted to be good, with a peak of Kp4 on the 12th of November. There is a slender coronal hole on the Sun that could cause the Kp index to rise this weekend, ending the 10th, due to its associated solar wind stream. However, it shouldn’t be too bad and any poor HF conditions are likely to be short-lived. Finally, NOAA has updated its progression forecast for Solar Cycle 25. It now predicts that this cycle will peak somewhere between January and September 2024 with a solar flux index of around 167 to 201. And now the VHF and up propagation news from G3YLA and G4BAO The present spell of unsettled weather at the end of the first week of December will run into the first half of next week. This brings a limited chance of rain scatter on the GHz bands, but there is a strong signal in the models for a major change of weather patterns for the middle of next week.  This will be the arrival of high pressure around Wednesday the 13th that will probably last into the following weekend, although there is some model variation in how quickly it will move away. The main result is that, although it begins as a cold air with high pressure with frosts, it will probably develop surface temperature inversions, which will be useful for Tropo. Towards the end of next week, as the centre of the high drifts east, it will allow more moist air at the surface and produce stronger ducting potential as well as develop an upper-level inversion for longer DX paths into the continent. The evening of the 14th of December sees the peak of the biggest and most reliable meteor shower of the year. The Geminids have the potential for a zenithal hourly rate of 150. The higher 50MHz and 144MHz activity usually provide the best chances, and a reasonably quiet QTH with 100W and a beam will bring you plenty of digimode QSOs. QSOs are even made by EME-class stations on the 70cm band and strong, long reflections on the lower bands can allow SSB QSOs if you’re persistent enough. That said, MSK144 and FSK441 digimodes will be the most reliable. Aurora remains a possibility, but the isolated out-of-season sporadic-E blips on the Propquest NVIS plots last month have quietened down for now. For EME operators, Moon declination is negative, falling further and reaching its minimum on Thursday the 14th. Path losses are falling towards a minimum at perigee on Saturday the 16th. 144MHz sky noise is moderate until the 12th and 13th when the Moon and Sun are close in the sky. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 3rd December 2023

GB2RS News Sunday the 3rd of December 2023 The news headlines: ITU World Radiocommunication Conference 2023 update Youth country representatives sought YOTA month has begun   The 2023 World Radio Conference has reached the halfway point in its four-week deliberations. After numerous meetings, the 23cm topic has made progress at the sub-working group level, and the outcome is expected to progress up the WRC committee structure for adoption. Meanwhile, attention is also being paid to a wide variety of other current and future agenda proposals where amateur frequency allocations are in scope, from HF and VHF upwards into the microwave bands. IARU President Timothy Ellam, VE6SH arrived to support the amateur radio team at the Conference and was able to record an ITU interview which is available online. The RSGB special focus page continues to have regular updates and additional details. You can find the page at rsgb.org/wrc-23 The RSGB is looking for four licensed radio amateurs to help raise the profile of wireless communication amongst young people. Initially, we’re looking for RSGB members based in England, Northern Ireland, Scotland and Wales to engage young people in the hobby. Volunteers in these new roles will represent the RSGB at externally organised events and will plan and deliver outreach events. If you have plenty of ideas, a passion for getting young people involved in amateur radio and experience of running small-scale events, we would be very keen to hear from you. For full details of these roles visit rsgb.org/volunteers and for an informal discussion please email RSGB Board Director, Ben Lloyd, GW4BML via [email protected] Youngsters on the Air month has now begun. Callsign GB23YOTA is active for the duration of the month, with a range of groups, clubs and individuals having reserved operating slots. Cray Valley Radio Society is active with the callsign between 12 pm and 6 pm today, the 3rd. Tomorrow, Monday the 4th of December, Wick High School is the first of several schools this week to be operating GB23YOTA. It will be on the air between 8 am and 5 pm. Sandringham School will be active on Wednesday the 6th of December between 8 am and 4 pm, as well as Mallaig High School who will be hosting the callsign on Thursday the 7th of December between 8 am and 3 pm. Finally, for this week, the RSGB National Radio Centre will be operating as GB23YOTA on Saturday the 9th of December between 9 am and 5 pm. Remember to listen out and have a QSO with a young radio amateur on the air. If you’d like to get involved, you’ve still got time. Email Jamie, M0SDV at [email protected] to register your interest or ask for further information.  The latest RSGB 2023 Convention video to be released is three presentations in one, on the topic of the 23cm band. Barry Lewis, G4SJH talks about amateur and RNSS coexistence in the 23cm band, then John Worsnop, G4BAO considers how the possible RNSS changes will affect narrow band DX and Earth Moon Earth operation. Finally, Dave Crump, G8GKQ looks at the future of ATV on the 23cm band. These presentations were given before the WRC23 conference, and final arrangements will depend on the WRC23 outcome. You can watch the presentation on the RSGB YouTube channel at youtube.com/theRSGB The last of the RSGB’s Tonight@8 webinars for 2023 is on Monday the 11th of December.

American and Canadian stations also send their ARRL or RAC section. The ARRL 10m Contest starts at 0000UTC on Saturday the 9th of December and ends at 2359UTC on Sunday the 10th of December. Using CW and Phone on the 10m band, the exchange is signal report and serial number. American, Canadian and Mexican stations also send their state or province code.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 30th of November 2023 We were lucky last week – the solar flux index remained quite high and, after the geomagnetic upsets around the 25th, we had settled conditions, with the Kp index below two. Unfortunately, it looks like that is all about to change. On Tuesday the 28th, two M-class solar flares and associated coronal mass ejections caused a plasma cloud to be directed towards Earth. It is expected to catch up with an earlier coronal mass ejection, or perhaps arrive shortly thereafter. Moderate G2 storming with a chance for strong G3 storming can therefore be expected, with an increased Kp index. If this wasn’t bad enough, a very large coronal hole is rotating into an Earth-facing position as well. This became geo-effective on the 2nd of December, and we can therefore expect any associated plasma in the solar wind early next week. Just how bad it will be is hard to say as it will largely depend on the interplanetary magnetic field of the plasma coming off the Sun. If it's north-facing we might just dodge the bullet but, if it is south-facing, we can expect significant auroral displays and propagation to match. Either way, it will be worth keeping an eye on solarham.net and also the upper HF bands for signs of auroral-type activity. After an initial surge in the MUF, we can expect band conditions to decline for at least a day or two. So, all in all, then, we can expect the bands to be disrupted at the end of this weekend ending the 3rd of December. Next week NOAA predicts the worst will be over by the 8th of December, but we are in uncharted territory and can expect anything to happen. So, work the HF DX if and when you hear it! On a side note, we are now heading towards winter propagation conditions so expect to hear DX activity on Top Band and 80m at night and especially around sunrise. The 40m band may also throw up some surprises during late afternoon.   And now the VHF and up propagation news The weak but cold easterly pattern is providing some sharp frosts, and scattered showers suggest that Tropo is not likely. However, the overnight cooling temperature inversion inland, or anywhere away from the East Coast, could see temporary Tropo develop overnight and up to about mid-morning. The showers themselves are mostly fairly shallow and don’t look wonderful from a rain scatter perspective. All of this changes by mid-week as low pressure starts to dominate again and really takes control for the rest of the coming week. This will bring stronger winds, spells of heavy rain and a return to milder air again. It does not, however, encourage thoughts of Tropo becoming a big player next week! Don’t forget to check in the early mornings for random meteor scatter opportunities and keep an eye on the Kp index for possible aurora. This is the better option with such an active Sun at the moment and, as we said earlier in the HF report, seems to be a strong player as we finish this first weekend of December. For EME operators, Moon declination is positive and falling, going negative on Thursday the 7th. Monday the 4th is apogee when the Moon is furthest away so expect path losses to be at their highest. 144MHz sky noise is low all week. And that’s all from the propagation team this week.

On Tuesday the 28th of November, the SHF UK Activity Contest runs from 1930 to 2230UTC. Using all modes on the 13cm band, the exchange is signal report, serial number and locator. On Wednesday the 29th of November the UK and Ireland Contest Club 80m Contest will run from 2000 to 2100UTC. Using CW on the 80m band, the exchange is your six-character locator. The UK Six Metre Group’s Winter Marathon runs from Friday the 1st of December 2023 to Wednesday 31st of January 2024. Using all modes on the 6m band, the exchange is signal report and locator. The ARRL 160m Contest starts at 2200UTC on Friday the 1st of December and ends at 1600UTC on Sunday the 3rd of December. Using CW on the 160m band, the exchange is a signal report. American and Canadian stations also send their ARRL or RAC section. On Sunday the 3rd of December, the 144MHz Affiliated Societies Contest runs from 1000 to 1400UTC. Using all modes on the 2m band, the exchange is signal report, serial number, and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 23rd of November 2023 What a difference a week makes! Last week the solar flux index was at 118 but, by Thursday the 23rd, it had climbed up to 190 with the Sun’s surface covered in spots with up to nine groups showing. The maximum useable frequency over a 3,000km path was estimated at more than 40MHz at times. This, coupled with a Kp index of around two to three, was quite good for HF. But it isn’t all good news. There has been quite a bit of solar flare activity, and the promise of more to come. A significant eruption was recently observed beyond the northeast limb. This may result in a coronal mass ejection, but this will likely be directed away from Earth. Active regions 3490 and 3492 remain the main regions of focus and are listed as the most likely to produce a noteworthy solar flare. The current flare threat stands at 55% for a moderate M-Flare and 10% for a strong X-Flare. DX this week included 4W8X in Timor-Leste and Don, 3B8/G3XTT in Mauritius. The 10m band was good last week with the KQ2H repeater on 29.620MHz FM coming in strongly in the afternoon. There were plenty of SSB signals to work between 28.4 and  28.5MHz as well. A scan from 28.200MHz to 28.300MHz around 2pm on the 23rd revealed plenty of beacons being received including IQ8CZ, IQ8BB and IZ8RVA in Italy; SV6DBG and SV2RSS in Greece; WW2BSA in New Jersey; K4PAR in Georgia; KA3JOE in Pennsylvania; and K5AB in Texas. All of these run less than 20W. For a full list of 10m beacons choose ‘Beacons and Repeaters’ from the ‘On the air’ tab at rsgb.org Next week NOAA predicts that the solar flux index may decline to be in the range of 145 to 155. Geomagnetic conditions may be reasonably settled with a Kp index of two to three, although a coronal mass ejection or two could soon alter that! So, make the most of the good HF conditions while you can, especially in this weekend’s CQ World Wide DX CW Contest. And now the VHF and up propagation news Weather patterns are settling and, with the current cold north-westerly wind, there are signs of something useful for eastern areas in the form of potential rain-scatter from heavy showers running down the North Sea.  In the west, we have an area of high pressure with a chance of Tropo but, in cold low-level air near the surface, this may not be very reliable. The chance of high-pressure building is probably limited and we are already seeing a return to more changeable weather. The bulk of the coming week will be controlled by low pressure with rain or showers. So, we have the possibility of further rain scatter, but little chance of significant Tropo, except perhaps if high pressure tries to make a comeback in the north the following weekend.  The November Orionids meteor shower is making an appearance on the 28th with a low Zenithal Hourly Rate, or ZHR, of three per hour for meteor scatter operators.  Keep checking for auroral modes and don’t forget that this can give LF bands a flutter to the signal, as was heard on 40m CW on Wednesday evening. In really strong events with a Kp index above, say, six then check the usual places for activity on the 6, 4 and 2m bands. For EME operators, Moon declination is positive and rising to maximum on Wednesday the 29th. Path losses are low to start the week but rising. 144MHz sky noise is low to moderate all week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 19th November 2023

GB2RS News Sunday the 19th of November 2023 The news headlines: World Radio Conference WRC-23 VHF Contest Committee survey “Taking Amateur Radio into schools” RSGB presentation released   World Radio Conference WRC-23 opens on Monday the 20th of November. Over the coming four weeks, a wide variety of agenda items will be considered, of which the 23cm band is a high-priority item for amateur radio. IARU volunteers have worked hard over the past four years in preparation for this. The RSGB will be attending as part of the Ofcom UK delegation. The RSGB’s social media and special focus page at rsgb.org/wrc-23 will feature regular postings whilst the conference is underway.  Following a really productive contest forum at the RSGB Convention, and a number of suggestions generated by the committee or raised in discussions with contesters, the VHF Contest Committee would like feedback to help finalise the VHF Contest rules for next year. The survey doesn’t have many questions so it shouldn’t take more than a couple of minutes of your time to fill it out, but the committee would really appreciate your views. Of course, there is also an opportunity for you to give feedback outside of those specific questions. You’ll find the survey at tinyurl.com/VHFCC and it will remain open until the end of the month. As part of its commitment to outreach and the growth of amateur radio, the RSGB has released a presentation from its 2023 Convention, called “Taking amateur radio into schools”. Lyall Smith GM4XID, Chris Leviston M0KPW, and Simon Harris G4WQG, share their experiences of inspiring school pupils to explore and have fun with amateur radio. Lyall set up an amateur radio club in his school whilst Chris started an afterschool club at his daughter’s primary school. Simon, with the help of friends at his amateur radio club, created links with his son’s technical college that have snowballed to other schools in the area. The presentation shows how individual radio amateurs and clubs can make positive and productive links with schools and will give you tips and encouragement for getting involved with your local schools. The Bath Based Distance Learning team has helped over a thousand students to pass UK amateur radio exams with pass rates consistently above the national average. The next Intermediate course will run from January to May 2024. Students will receive weekly work packages via a virtual classroom. There will be no charge for the training, but students will need to provide their own textbook, scientific calculator, electronic parts and tool kit. Students will also have to arrange their own exam at the end of the course, but advice will be provided at the appropriate time. As part of the application process, there will be some pre-course work to ensure students are able to use the online learning systems and to be sure they are ready to study in January. To receive course application details, please email Bath Based Distance Learning Team Leader Steve, G0FUW, via [email protected] The RSGB National Radio Centre at Bletchley Park will be closed on Christmas Eve, Christmas Day, Boxing Day and New Year’s Day. There will be reduced hours on New Year’s Eve when the Centre will be closing at 2 pm. Following the seasonal closures, the RSGB National Radio Centre will also be closed for essential maintenance works between the 2nd and 5th of January 2024. Outside of these times, volunteers look forward to welcoming visitors as usual. Remember that RSGB Members can download a free entry voucher for Bletchley Park from the RSGB website rsgb.org/bpvoucher Please send details of your news and events to [email protected]  The deadline for submissions is 10 am on Thursday before the Sunday broadcast.   And now for details of rallies and events The Coulsdon Amateur Transmitting Society Bazaar is taking place today, Sunday the 19th of November.

QSL via OQRS, Logbook of the World, eQSL or via IK2GZU.   Now the contest news On Tuesday the 21st of November, the 1.3GHz UK Activity Contest runs from 2000 to 2230UTC. Using all modes on the 23cm band, the exchange is signal report, serial number and locator. On Thursday the 23rd of November, the Autumn Series CW Contest runs from 2000 to 2130UTC. Using CW on the 80m band, the exchange is signal report and serial number. The CQ World Wide DX CW Contest runs from 0000UTC on Saturday the 25th of November to 2359UTC on Sunday the 26th of November. Using CW on the 160 to 10m bands, where contests are permitted, the exchange is signal report and CQ zone. The UK is in zone 14.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 16th of November 2023 We had another roller-coaster week with periods of reasonably settled geomagnetic conditions followed by more unsettled times. Luckily, it didn’t get too bad, as it did when the Kp index hit seven the week before. This, coupled with a lower solar flux index of 119 on Thursday, has meant HF conditions have not been outstanding. However, we are still buoyed by the seasonal HF conditions, which are generally good in Autumn. Propquest shows that the F2-layer critical frequency is still maxing out at more than 12MHz around noon. The F2-layer critical frequency is the highest at which radio waves are returned back to Earth when sent directly up into the ionosphere. This gives us a maximum usable frequency, or MUF, over a 3,000km path of more than 40MHz. Interestingly, it also gives us an MUF over a 500km path of more than 14.7MHz. So, look out for long-distance inter-G signals around noon, or thereabouts, on the 20m band. The 30m band remains a pretty solid inter-G band from late morning to mid-afternoon. Getting back to the geomagnetic conditions, the Bz component of the interplanetary magnetic field or IMF has been pointing south for long periods which is why the Kp index has been higher than normal. This means the IMF more easily couples to the Earth’s magnetic field, just like two bar magnets aligned north against south. Next week, NOAA predicts the solar flux index will rise again, perhaps reaching 140 by the end of the week. However, it also forecasts unsettled geomagnetic conditions from the 22nd  to the 25th, with a forecast Kp index of up to 5. So, get your HF DXing in early next week!   And now the VHF and up propagation news The seemingly never-ending period of unsettled weather is likely to continue into the coming week. This means another week with only a limited chance of Tropo for most parts of the country. As something of a longshot, it's worth noting that southern parts of England, especially along the Channel coast, may have access to higher pressure over Biscay after the middle of next week for chance Tropo paths south into western France or northern Spain. For the rest of us, the weather pattern is rather changeable with a tendency for north-westerly winds. At this time of year, this can often mean that showers form over the surrounding seas. Rain scatter options could be worth checking for stations around the Irish and North Sea coasts. Meteor scatter is also worth considering, in view of the peak of the Leonids, on Friday the 17th and Saturday the 18th, at the beginning of this first weekend. It's quite a broad period of activity and, with the minor Moncerotids shower peaking on the 22nd, conditions could still be good throughout the new week. Lastly a thought about the chances of aurora and the busy solar activity: it's worth keeping a check on the planetary Kp index for signs of aurora – look for a Kp above six. For EME operators, Moon declination starts at a minimum but rises all week, going positive again late on Wednesday. Losses are at their lowest with Moon perigee on Tuesday the 21st. 144MHz sky noise is low all week. Perigee is when the Moon is at its closest point to Earth. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 12th November 2023

GB2RS News Sunday the 12th of November 2023 The news headlines: RSGB Construction Competition RSGB 2023 Convention videos RSGB QSL Bureau    Now the nights are drawing in, don’t forget about the RSGB Construction Competition. To enable members across the country, and even the world, to take part, entries will again be judged over the internet rather than in person. This year two new categories have been introduced so there are six categories you can enter: Antennas; Beginners; Most creative and/or elegant PCB Design; Construction Excellence; Innovation; and Software and Systems. Special recognition will be given to entries submitted by radio amateurs under the age of 24, and to those who have just gained their Foundation licence. A cash prize will be awarded for the winner of each section, with a bonus for the overall winner, who will also be given the Pat Hawker G3VA Award. The deadline for entries is the 1st of March 2024 and you can find out more, including how to enter, on the RSGB website at rsgb.org/construction-competition The RSGB has released three presentations from its 2023 Convention. The first is the keynote speech in which Colonel John Doody talks about his life in the RF Spectrum during the last 60 years and asks, “Is this a life for you?”. The second presentation is by the RSGB President, John McCullagh, GI4BWM who talks about his experience of 50 years of RSGB membership and explains the wide range of services that are offered to members. He finishes with an overview of the four strategic priorities that the RSGB Board has set until the 2024 AGM. The third presentation is the Discussion with the Board session that was hosted by Don Beattie, G3BJ who has been both an RSGB President and President of IARU Region 1. This builds on the four strategic priorities, includes questions from those attending this discussion forum and answers from the Board Directors. Although the three presentations are separate, the presentation by the RSGB President was immediately before the Board session at the Convention and is referred to in that discussion. You can find all three on the RSGB YouTube channel at youtube.com/theRSGB The RSGB QSL Bureau is pleased to advise that a replacement QSL sub-manager is now in place for the  M1, M3, M5, M6 and M7 QSL sub-groups. Ann Eastwood, M7ERT has kindly volunteered to take on all five busy groups. Members can again send 2nd Class stamped, C5-sized collection envelopes to the new address. Contact details are available from the RSGB website. Please remember to number each envelope and indicate your callsign and membership number in the top-left corner as usual. Essex CW Amateur Radio Club’s activity week runs from Monday the 13th of November to Sunday the 19th of November 2023. This is a friendly non-contest style event to encourage both experienced and new Morse operators. Slow speed operators are especially welcome. Whilst the objective is to contact as many radio amateurs as possible in a week, it is hoped that QSOs go beyond just an exchange of signal reports and become longer chats. Anyone who works at least 25 other stations qualifies for a free PDF award certificate. The stations worked don’t have to be Essex CW Amateur Radio Club members. So, please dust off your key or paddle and get on the air! Listen out for Essex CW club callsigns GX1FCW and GX8CW during the event. More information, and a list of preferred frequencies, can be found at essexcw.uk Please send details of your news and events to [email protected]  The deadline for submissions is 10am on Thursday before the Sunday broadcast.

On Saturday the 18th, the second 1.8MHz Contest runs from 1900 to 2300UTC. Using CW on the 160m band, the exchange is signal report, serial number and District Code.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 9th of November 2023 Last week was characterised by very unsettled geomagnetic conditions which took their toll on the high-frequency bands. The Kp index hit seven on the 5th of November, sparking visible aurora all over the UK. This also caused auroral conditions on the bands with many people commenting on the auroral flutter on the lower HF bands and hearing auroral-type signals on the 10m band. Unfortunately, these conditions didn’t improve very quickly, and the upper bands were badly affected as the subsequent geomagnetic storm continued. By late afternoon on the 6th, HF began to return to normal with MUFs over a 3,000km path hitting more than 28MHz again. The solar flux index, at this point, was 146, with eleven C-class flares being detected on Monday, but nothing worse. Unsettled geomagnetic conditions continued on and off until the morning of Thursday the 9th when the Kp index finally got down below four and stayed there. A quick check of the 10m band on Thursday afternoon revealed the W1AW CQ practice transmissions on 28.0675MHz, plus two to ten-watt beacons audible from Gibraltar, Italy, Greece and the Eastern seaboard of the USA. The band was open, but not exactly humming! Also on Thursday, the data feed to Propquest.co.uk failed, resulting in a lack of graphs for the F2-layer critical frequency and extrapolated MUFs. Let’s hope it returns quite quickly. Next week, NOAA predicts that the solar flux index will be around 150 and the Kp index will be around 2 or 3. If that is the case, we can expect conditions to be a little better. But, as always, a coronal mass ejection could soon put an end to the fun with an increased Kp index and decreased MUFs. And now the VHF and up propagation news The current spell of unsettled weather is likely to continue for another week at least, with some fairly strong weather systems possible, which could bring gales and heavy rain. With fast-moving systems it’s pointless, with such a long lead time, to try and nail down the exact timings of each individual system. Once again, Tropo will not be a big player in VHF/UHF operating this week, except perhaps over this weekend, the 11th and 12th, as a transient weak ridge crosses the country. You might still see the odd ’spike’ of higher E-layer critical frequencies on the propquest.co.uk NVIS charts when it comes back online. Lately, these have been during the mid-morning period so maybe give the 10m and 6m bands a cursory check during the coming week. It's not entirely clear why the bands have been so reliable during the recent week, but may be a response to meteor input. We are approaching the peak of the Taurids meteor shower over the 12th and 13th of November. This is followed by the much larger Leonids towards the end of next week on the 17th and 18th of November. This also means that it's worth listening for some meteor scatter signals throughout the next week or so. There was a nice auroral opening on 6m up to 2m late in the afternoon on the 5th of November, with the planetary Kp index reaching 6 to 7. This produced rare visual aurora sightings down to the south coast. Auroral CW and SSB signals sound  ‘watery’ on the LF bands and very raspy and whispery on HF and VHF. For EME operators, Moon declination is negative and falling again, reaching a minimum on Thursday the 16th. Path losses continue to fall and 144MHz sky noise is low, apart from Monday the 13th when the Sun and Moon are close in the sky. From Wednesday, it rises to a high of 2,900 Kelvin on Thursday. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 5th November 2023

GB2RS News Sunday the 5th of November 2023 The news headlines: • Exam funding for youngsters • Tonight@8 webinar • RSGB affiliated club Course and Exam Finder map The Radio Communications Foundation, or RCF, is a small charity that seeks to promote radio engineering and amateur radio. Last year, several teachers identified the cost of Foundation exams as a barrier for some young people. The RCF Trustees considered how they might help. Funding exams for every youngster was seen to be unaffordable, and unnecessary, in many cases. As a start, and to help those with the greatest need, the Trustees have agreed to fund 60 Foundation exams each year. The funding will be available to anyone who is under the age of 21, in full-time education and needs help with the exam fee. Fifteen exams will be funded every three months. The first batch of 15 exams will be funded in January 2024. If any of the allocated funds are not used, they will be rolled over to the next quarter. No money will change hands as the RCF Trustees will simply make the bookings and pay the RSGB. In time, there will be a simple online application form. In the meantime, anyone seeking funding should send their details to [email protected] with a supporting statement from a parent or guardian about why they would benefit from an RCF-funded exam. Details of their interest in amateur radio, and how they have trained, or are training, for the Foundation exam will also help the Trustees make their decisions. If the scheme proves to be successful, and amateurs continue to donate to the RCF, there may be scope for increasing the number of exams funded each year. Further details about the RCF, and how to donate, can be found at commsfoundation.org Don’t forget to be part of the RSGB’s Tonight@8 webinar tomorrow, Monday the 6th of November. Colin Summers, MM0OPX will give an entry-level talk aimed at newcomers to amateur radio. He will touch on antennas generally but will focus on the end-fed half-wave antenna including details of construction, transformers and performance. Find out more at rsgb.org/webinars The RSGB-affiliated club Course and Exam Finder map has been relaunched this week. All affiliated clubs were invited by email to submit information about the courses and exams that they run. The replies that were received are now on the RSGB website. If you use the search function and it doesn’t show any results, you will need to widen your search area. If your club provides training or holds exams and it isn’t shown on the map, please go to rsgb.org/examupdate and complete the form. If you need any help, you can email [email protected]  Additional information will be uploaded each week, so please submit any changes before 3 p.m. on Fridays. The RSGB is delighted to welcome Elaine Richards, G4LFM as the new volunteer RSGB Archivist. Elaine is a former RadCom Managing Editor and was keen to continue to oversee the RSGB archives when she retired from her RadCom role last year. If you would like more information about an old amateur radio photo or document or want to check something in the RSGB archives, you can contact Elaine via [email protected] Thank you to everyone who bought raffle tickets at the RSGB Convention last month to raise money for the DXpedition Fund.

On Sunday the 12th, the UK Microwave Group Low Band Contest runs from 1000 to 1400UTC. Using all modes on 1.3 to 3.4GHz frequencies, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 2nd of November 2023 The last two weeks have not been too bad for HF propagation, but not particularly good either. The solar flux index hit lows of 119 on the 22nd of October and 121 on the 24th, but subsequently recovered and stood at 159 on Thursday the 2nd of November. This at least allayed the fears of some amateurs that Solar Cycle 25 was over! But, as the solar flux index rose, geomagnetic conditions became slightly unsettled. The maximum Kp index was 4.67 on the 29th of October but has subsequently recovered to between 1 and 3. This didn’t affect HF too much with the daylight maximum useable frequency over 3,000km remaining steadfastly over 28MHz all week, even hitting 43MHz on Thursday the 2nd. As a result, the bands have been humming with lots of DX being worked. Phil, GU0SUP reports working Jan, E51JAN on the North Cook Islands on 12m FT8 Fox and Hound mode at around 1630UTC. He said that, as it was almost dark, he didn't expect to hear anything, but had a good copy on him at 190 degrees, so gave him a call. He came straight back. Phil said that this was a big surprise, and he is not sure how it worked. It was quite a skewed path, with pretty much no copy on the real headings, short or long path. He also worked YJ0TT Vanuatu on 10m at 0843UTC that morning, and later at 1741UTC on 20m FT8 Fox and Hound mode. As Phil said: “Two new DXCCs in one day!” So, the moral of the story is to keep on trying – you never know what you will work! Next week NOAA predicts that the solar flux index will decline slightly to the 130s. A bigger problem is a massive coronal hole, which is rotating into an Earth-facing position. This could cause the Kp index to rise, possibly on Sunday the 5th or Monday the 6th.  NOAA also predicts a geomagnetic disturbance on November 9th when the Kp index could rise to four. Otherwise, it suggests fairly settled conditions and a general Kp index of two. As always, keep an eye on solarham.net for up-to-date information. And now the VHF and up propagation news The current spell of unsettled weather with areas of low pressure, strong winds and rain or showers will probably remain over the coming week to the 12th of November. This again suggests that Tropo will not be a feature of VHF/UHF operating and perhaps there are just a few weak options for rain scatter to lift the mood.  Since comments last week about out-of-season Sporadic-E propagation, we are still getting weak Sporadic-E signals on the graph plots on propquest.co.uk which peaked at 5.35MHz at Dourbes on Wednesday the 1st of November, at 1700UTC. This may have been enough to produce paths on 6m band data modes. Favoured times of day for these chance events are typically around 10 a.m. or 5 p.m. Meteor scatter prospects are still good since the decaying Orionids are probably lingering up until the 7th, and we approach the peak of the Taurids around the 12th of November. The week after, we’ll be looking forward to the November Leonids. So if you’ve not tried meteor scatter yet, this may be a good time to read up on modes, frequencies and operating techniques. Lastly, a brief mention of aurora, which is always possible given a decent coronal hole event like last week. So keep a check on the Kp index for larger values above, say, 5. For EME operators, Moon declination is at maximum this weekend, meaning long Moon windows and high Moon elevation. Path losses are at their highest over the period due to apogee on Tuesday the 6th and 144MHz sky noise is low all week. And that’s all from the propagation team this week.

Stations entering the four-hour contest may also enter the two-hour contest. On Wednesday the 1st of November, the UK and Ireland Contest Club 80m Contest runs from 2000 to 2100UTC. Using SSB only on the 80m band, the exchange is your six-character locator. The 144MHz CW Marconi Contest starts at 1400UTC on Saturday the 4th of November and ends at 1400UTC on Sunday the 5th of November. Using CW on the 2m band, the exchange is signal report, serial number and locator.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 26th of October 2023 It was not a good week for the ionosphere with the Solar Flux Index, or SFI, falling to less than 130, plus some disturbed geomagnetic conditions as well. On Wednesday the 24th, the SFI fell to 121, while the following day the Kp index hit 4.33 thanks to a coronal mass ejection from a filament eruption. Minor to strong geomagnetic storms continued on Thursday afternoon and evening with a warning that Aurora sightings may have been possible in the north of the UK that evening. So, does this mean that Solar Cycle 25 is over? Most definitely not! NOAA’s Space Weather Prediction Center has just issued a revised prediction for solar activity during Solar Cycle 25, saying solar activity will increase more quickly and peak at a higher level than that predicted by an expert panel in December 2019. The updated prediction now shows Solar Cycle 25 peaking between January and October of 2024, with a maximum sunspot number between 137 and 173. Meanwhile, the critical frequency remained relatively high at around 11 to 12MHz around lunchtime, which still gives a maximum usable frequency, or MUF, for paths over 3,000km of more than 28MHz. October remains a good month for higher-band HF propagation with many reports of contacts into the Pacific on the 15, 12 and 10m bands. The bad news is that this weekend’s CQ World Wide SSB Contest could be hit by poor geomagnetic conditions later on. Two large coronal holes on the Sun recently rotated into an Earth-facing position which could mean a raised Kp index and reduced MUFs. A coronal hole is a cooler, less dense region of the Sun with open magnetic field lines that allow solar plasma to flood out. We expect the solar material to hit the Earth today, the 29th, either in the afternoon or evening, perhaps continuing into Monday, with an associated warning of aurora as the Kp index rises. Looking to next week, NOAA predicts the SFI will increase, perhaps hitting the 140 to 145 mark by the end of the week. The ionosphere may also remain unsettled until around Wednesday the 1st of November, although the rest of the week should be better. And now the VHF and up propagation news This autumnal weather pattern is keeping up its attack on the UK during the coming week.  This means that low-pressure systems will remain in control and it’s unlikely that Tropo will get much of a look-in! That leaves rain scatter as the best of a bad bunch with heavy rain, especially any heavy showers around the coasts, being the most likely to offer good reflection points for GHz band operators. The remaining options for propagation are aurora, which is not entirely out of the question since we have a large coronal hole navigating its way into a favourable position, as was mentioned earlier. There are many websites and widgets that show the latest Kp value and it’s definitely worth adding one to your favourites list. The other mode of possible interest is that of meteor scatter and, although we have just passed the peak of the Orionids, it came along just right for the 6m Affiliated Societies Contest on Sunday the 22nd of October, when some out-of-season Sporadic-E propagation made a welcome appearance with paths to Italy, Sardinia and Spain being reported. The slow decay of the Orionids means that we still have the coming week to enjoy the remnants until early November. For EME operators, Moon declination is positive and rising this week with lengthening Moon windows and increasing Moon elevation. Path losses start low but are increasing. 144MHz sky noise is moderate, peaking at 500 Kelvin on Wednesday the 1st of November. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 22nd October 2023

GB2RS News Sunday the 22nd of October 2023 The news headlines: RSGB 2023 Convention ARISS contact with St Peter-In-Thanet CE Junior School Tonight@8 webinar The RSGB’s 2023 Convention took place last weekend and brought together hundreds of amateurs in person as well as many more across the world who watched the livestream. RSGB General Manager and Convention Chair, Steve Thomas, M1ACB said that in addition to the usual varied programme of lectures, he was delighted as Convention Chair to have led the team that introduced new aspects to the weekend, such as the all-day drop-in Buildathon on Saturday which encouraged people to enjoy making something for themselves, and also to learn how to run a similar event at their local club or group to help others develop practical skills. The RSGB Convention saw presentations about taking amateur radio into schools, young radio amateurs travelling to YOTA camp, as well as the usual mix of fascinating technical talks about many aspects of amateur radio today. There were also more RSGB Committees and Groups at the Convention to highlight the important work that the RSGB does through its volunteers. Steve said that the Convention planning team is already receiving an overwhelming amount of positive feedback, but he encourages anyone who attended the Convention to complete the feedback form if they haven’t already done so - go to rsgb.org/feedback and share your thoughts. The Society will share a small number of Convention presentations on YouTube over the coming weeks and will provide many more for members to view as part of the benefit of RSGB membership. In addition, you will be able to watch a series of special interviews that were recorded over the weekend. The interview with the RSGB and IRTS Presidents has been released this week and you can see it on the RSGB YouTube channel and also on the RSGB Convention web page at rsgb.org/convention  Children at St Peter-In-Thanet CE Junior School in Broadstairs, Kent had an ‘out of this world’ experience this week, with an ARISS contact between the school and NASA astronaut Jasmin Moghbeli, KI5WSL on board the International Space Station. It was an exciting and inspiring day for all involved. RSGB Board Chair Stewart Bryant, G3YSX attended the event and met ESA reserve astronaut Meganne Christian, who encouraged the children to ‘dream big’. The event, which featured on local BBC and ITV news programmes that evening as well as BBC Radio Kent, can be watched on the ARISS YouTube channel. The RSGB polled its Facebook group for new and returning licensees, which showed that basic introductions to contesting and antennas were the top two topics of interest. In October the RSGB ran a Tonight@8 webinar which covered an introduction to contesting, and in November it is focusing on antennas. On Monday the 6th of November, Colin Summers, MM0OPX will give an entry-level introduction to antennas generally, including a focus on end-fed half-wave antennas, transformers, construction and performance. Join the presentation and ask questions live on the RSGB YouTube channel or special BATC channel. To find out more about this, and other RSGB webinars, go to rsgb.org/webinars Today is the last day of Jamboree on the Air, also known as JOTA. The event promotes friendship and global citizenship and is a brilliant celebration of amateur radio among the Scout Association. There are many stations active over the weekend so please listen out for the young operators on the air. Some groups have shared details of callsigns that are active over the weekend and the RSGB has compiled a list on its website – go to rsgb.org/jota and choose the “JOTA Stations on the Air” link on the right hand side of the page. The RSGB would love to see your photos of Scouts getting involved with JOTA, so tag the RSGB and also use the hashtag JOTAJOTI to be involved in the conversation on social media. There will be a report in RadCom so please send details and photos from your event to [email protected] by the 14th of November. A reminder that the RSGB National Radio Centre will be closed to the public from Saturday the 28th of October until Sunday the 5th of November inclusive because Bletchley Park will be hosting the first global summit on Artificial Intelligence. Please note that this closure period includes an additional two days than was previously announced by Bletchley Park.

On Tuesday the 24th of October, the SHF UK Activity Contest runs from 1830 to 2130UTC. Using all modes on 2.3 to 10GHz frequencies, the exchange is signal report, serial number and locator. On Wednesday the 25th of October, the UK and Ireland Contest Club 80m Contest runs from 2000 to 2100UTC. Using CW on the 80m band, the exchange is your six-character locator. On Thursday the 26th of October, the Autumn Series SSB Contest runs from 1900 to 2030UTC. Using SSB on the 80m band, the exchange is signal report and serial number. The CW World Wide DX SSB Contest starts at 0000UTC on Saturday the 28th of October and ends at 2359UTC on Sunday the 29th of October. Using SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and CQ Zone. The UK is in Zone 14. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 19th of October 2023 We had a quieter week, with both lower sunspot numbers and better geomagnetic conditions. The Solar Flux Index was at 135 on Thursday the 19th, down from 156 the week before. Let’s hope this is a temporary lull in Solar Cycle 25’s progression. We had no M-class or higher flares to contend with and the Kp index was generally below 3 all week. Only on Thursday did things start to become a little more unsettled as the Kp index climbed to 3.67 in the morning, with warnings that worse may be to come due to a coronal mass ejection on the 16th of October. So, the earlier part of the week was best for HF propagation with many stations reporting DX contacts including T2C, a German DXpedition to Tuvalu, and YL2GM’s one-person DXpedition to Tristan da Cuhna. It's nice to see DX opening up, especially on the higher bands. Propquest.co.uk reports that, generally, the maximum useable frequency over a 3,000km path remains above 28MHz during daylight hours so make the most of the 10 and 12m bands. The maximum usable frequency, or MUF, is the highest radio frequency that can be used for transmission between two points on the Earth by reflection from the ionosphere. Next week NOAA predicts that the Solar Flux Index will rise to around 145 all week while geomagnetic conditions are predicted to be stable with a Kp around 2 to 3. But, as always, watch out for coronal mass elections and their impact. And now the VHF and up propagation news We are struggling to find anything optimistic regarding Tropo in this unsettled spell of weather and again it may well be down to rain scatter to provide the entertainment. Once out of the summer thunderstorm season, the results are rarely as good, even though you’ll be spoiled for choice! There will be a transient weak ridge over some eastern areas on Tuesday, but only acts as a separator between the lows and is not expected to be effective for Tropo. Incidentally, in this fairly typical spell of unsettled autumnal weather, strong winds and heavy rain can be a notable feature and put stress on antennas and coax, so make a note of any weak points and use the next fine spell to put things right! What propagation remains is the usual stop-gap pair of modes – meteor scatter and aurora – both of which could be worth checking during the coming week. A reminder that the Orionids shower, active from the 2nd of October to the 7th of November, peaks today, the 22nd, with an average Zenithal Hourly Rate, or ZHR, of around 20. For EME operators, Moon declination reached minimum on Friday the 20th so the following week will see lengthening Moon windows. Next Thursday’s perigee means path losses are at their lowest this week. 144MHz sky noise starts high but falls throughout the coming week remaining low to moderate. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 15th October2023

GB2RS News Sunday the 15th of October 2023 The news headlines: • RSGB Construction Competition • New chair of the RSGB’s Exams and Syllabus Group • RSGB 2023 Convention The RSGB recognises the importance of construction as a key element of amateur radio, whether that is using traditional construction skills or is a software or systems engineering project. The Society has launched its 2024 Construction Competition and the deadline for entries is the 1st of March 2024. To enable members across the country, and even the world, to enter, entries will be judged over the internet rather than in person. This year a new category called ‘Antennas’ has been introduced so there are five categories you can enter: Beginners; Construction Excellence; Innovation; Software and Systems; and Antennas. Special recognition will be given to entries submitted by radio amateurs under the age of 24, and to those who have just gained their Foundation licence. A cash prize will be awarded for the winner of each section, with a bonus for the overall winner, who will also be declared the winner of the Pat Hawker G3VA Award. You can find out more, including how to enter, on the RSGB website at rsgb.org/construction-competition The RSGB is delighted to welcome Andrew Lenton, G8UUG as the new Chair of the Exams and Syllabus Review Group. The Society would also like to thank Donard de Cogan, M0KRK for his hard work and dedication, including chairing the Group for the past three years. You can contact Andrew via [email protected] The RSGB 2023 Convention takes place over both days this weekend. There is a fantastic range of presentations on a variety of amateur radio topics. If you haven’t already booked, you can buy day tickets on the door or join the Livestream at any time over the weekend. The Livestream contains 12 of the Convention presentations as well as exclusive interviews and additional content. We are asking radio amateurs to register for the Convention Livestream this year. Whether you are there in person, or joining radio amateurs from across the world online, make sure you are part of this major annual event. For more information about the full programme of presentations go to rsgb.org/convention and to register for the Livestream head over to rsgb.org/livestream As we get closer to the ITU World Radio Conference, WRC-23, which starts next month, the future of amateur radio, particularly the 23cm band, is of key importance. The ITU News Magazine has a feature article by IARU President Tim Ellam, VE6SH regarding amateur activity in the 23cm band. This is the topic of a challenging agenda item at the Conference which calls for measures that protect primary radio-navigation services such as Glonass and Galileo from amateur terrestrial and satellite usage. You can read the article by visiting tinyurl.com/TimVE6SH In related news, the IARU also reports that the last formal preparatory meeting ahead of the WRC on this topic was difficult and could not achieve a consensus on measures such as power and bandwidth limits, or frequency restrictions. The IARU supports further efforts and will continue to try to find a solution regarding suitable recommendations, whilst opposing the unwarranted statutory imposition of such. You can read the IARU’s post on this subject via tinyurl.com/ITUR23cm  Also, you can hear the latest updates at the RSGB Convention on Sunday, in a talk by IARU expert and RSGB Microwave Manager Barry Lewis, G4SJH.  Jamboree On The Air, or JOTA, is an annual event in which Scouts and Guides all over the world communicate with each other via amateur radio.

On Sunday the 22nd of October, the 50MHz Affiliated Societies Contest runs from 0900 to 1300UTC. Using all modes on the 6m band, the exchange is signal report, serial number and locator. The Worked All Germany Contest starts at 1500UTC on Saturday the 21st of October and ends at 1500UTC on Sunday the 22nd of October. Using CW and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. German stations also send their DOK reference. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 12th of October 2023 We had a period of low geomagnetic disturbance last week, which allowed the upper HF bands to shine. There were lots of reports of DX being worked on the 10m band as the Kp Index sat mainly in the ones and twos, with a maximum of Kp 3.33 for one three-hour period on the 9th. The Solar Flux Index, or SFI, also remained in the 150s and 160s, hitting a maximum of 166 on the 9th. All in all, these were very good conditions for high-band DXing, especially at this optimum time in the calendar. As promised last week, let’s take a look at HF paths from the UK to the W8S Swains Island DXpedition in the South Pacific. The good news is that operations are in full swing and are being spotted daily on the DX Cluster. At a distance of approximately 9,500 miles from the UK on the short-path, and 15,300 miles on the long-path, it’s quite a distance for signals to traverse. The short-path beam heading you need to select is a polar path at 350 degrees, and for long-path 169 degrees. The best openings to Swains from the UK start on the 20m band from about 0630UTC. As the morning progresses, move up in frequency until you get to the 10m band around 1000 to 1100UTC. This path should remain open until 1500 or 1600UTC, at which point you can drop down to the 12, 15 or 17m bands. Long-path openings may be a lot weaker, with a short opening on the 15m band from 0600 to 0800UTC. Then move to the 12 or 10m bands from 0700 to 0900UTC. There may also be a long-path evening opening from 1800 to 2000UTC on the 17 and 10m bands. The above predictions are for SSB and CW. You may find FT8 openings extend these times a little. For more details, and to compute your own predictions, see VOACAP.com or Proppy at soundbytes.asia/proppy This weekend, ending today the 15th, may see some geomagnetic disturbances due in part to a coronal hole. But, as long as we don’t get any coronal mass ejections, this should settle after the weekend.  The Solar Flux Index is predicted to remain in the 150s with a maximum Kp index of two. If this turns out to be true, we should have a good week of DX hunting to come. And now the VHF and up propagation news The coming period of weather offers many changes, and it looks as though we have said goodbye to the warm air, with low pressure controlling events.   Just a gentle reminder to keep an eye on your antennas as this time of year can produce surprisingly rapid developments of deep low-pressure systems with associated strong winds.  Early next week, a temporary high returns to give you a chance to give those antenna supports and guys a once-over while winds are light, and leave the potential Tropo until the evenings and overnight. Incidentally, this new high is essentially a cold air high, so may not be as productive as the recent Tropo of the week just ending. The new high will probably hang around until midweek when it should migrate north to allow an easterly wind across the south. This will probably bring some showery rain along the east coast. It's possible that we may have some rain scatter from these showers. Meteor scatter is always good in October, with high random meteor rates and a number of small showers. Most notable of these is the Orionids Meteor Shower which peaks on the 22nd of October and is active until the 7th of November with an average zenithal hourly rate of around 20. Of course, aurora is also worth keeping in mind if you get any spare time! For EME operators, Moon declination is negative and falling all week, reaching minimum on Friday the 20th with corresponding shortening Moon windows. As we are now past apogee, path losses will continue to fall.  144MHz sky noise starts very high with the annular eclipse on Saturday the 14th. The following week sees it moderate, increasing to a high of over 2000 Kelvin on Thursday. And that’s all from the propagation team this week.

Also on Wednesday the 11th of October, the 432MHz FT8 Activity two-hour Contest runs from 1900 to 2100UTC. Using FT8 on the 70cm band, the exchange is a report and four-character locator. Stations entering the four-hour contest may also enter the two-hour contest. On Thursday the 12th of October the 50MHz UK Activity Contest runs from 1900 to 2130UTC. Using all modes on the 6m band, the exchange is signal report, serial number and locator.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 5th of October 2023 Last week progressed quite well from a solar point of view, at least until the morning of Thursday the 5th when the Kp index rose to five. But the Kp high was short-lived and only lasted for one three-hour reporting period. Until this point, it had been around one to three all week, which meant the ionosphere had a chance to settle and build. As a result, we saw daytime MUFs over a 3,000km path rise well above 28MHz. This was partly due to the seasonal change, which sees daytime MUFs generally rise as we head towards autumn. Similarly, we are seeing nighttime MUFs declining as we progress through October. The times of seeing the 17 and 20m bands open all night are probably behind us now and they won’t be back until next summer! The Solar Flux Index held up quite well last week, peaking at 161 on the 1st of October, before declining slightly to 155 by Thursday the 5th. Propagation-wise, we are really starting to benefit from the autumnal changes. Stations worked from the UK recently include the 5W0LM DXpedition to Samoa on 20m CW. The team expects to be on air until the 14th of October. The big one this autumn is the W8S DXpedition to Swains Island, a remote coral atoll in the Tokelau Islands in the South Pacific Ocean. We will look at the propagation prospects for working W8S in the GB2RS News next week. Next week, NOAA predicts that the Solar Flux Index will remain in the 160s. It also predicts a Kp index of two all week. But, with eight active regions on the Sun at present, the risk of a solar flare and/or Coronal Mass Ejection remains high. So, don’t be surprised if we see the Kp index head skywards again, at times, with a reduction in the maximum useable frequency. And finally, the good news is that the Chilton Digisonde is now back in action. You can select it, as well as Dourbes, at propquest.co.uk And now the VHF and up propagation news This first weekend of October could be good for meteor scatter with the peak of the October Draconids tonight, the 8th, into the 9th of October. It should also be quite a good period for Tropo as high pressure over the south provides enhanced paths across the continent to France and Germany. There may also be a path across Biscay to Spain or the Canaries and Azores. Along with fine and unusually warm weather, it should fit in well with the October 432MHz to 245GHz Contest which ends at 1400UTC today, the 8th. Hopefully, there will still be something left for the 432MHz FM Activity Contest and UK Activity Contest on Tuesday the 10th. On the evening of Wednesday the 5th, an aurora alert arrived, so clearly that’s another mode to keep in mind. From around the 11th, we will find a trend towards more unsettled conditions with rain and showers and rather windy weather as low pressure takes charge. This will remove Tropo from the operating schedule but may give some rain scatter opportunities. For EME operators, Moon declination is just past maximum this coming weekend so, as the following week progresses, Moon elevation will fall from its high and Moon windows will shorten. With apogee on Tuesday the 10th of October, path losses are at, or around, their maximum. 144MHz sky noise is falling, reaching a minimum next Tuesday. The Sun and Moon are close in the sky on Saturday the 14th meaning high noise all weekend. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 1st October 2023

GB2RS News Sunday the 1st of October 2023 The news headlines: RSGB 2023 Convention RadCom Basics Editor retirement RSGB Director Ben Lloyd, GW4BML’s SOTA challenge We’re counting down to the RSGB 2023 Convention and the Society is putting the final touches to the programme. This year there will be a special, hour-long, session with the RSGB Board where the Directors will present the four strategic priorities that the Society will be focusing on until the 2024 AGM. After that, Convention attendees will have an opportunity to ask questions. This will be a positive and productive opportunity to discuss with the Board how the Society, and its members, can meet the challenges facing amateur radio today. The session will be hosted by Don Beattie, G3BJ, who is the former IARU Region 1 President as well as a former President of the Radio Society of Great Britain. The session will be recorded so if you are unable to attend the Convention but would like to hear a particular topic discussed, please email that topic with your name and callsign to [email protected] before Monday the 9th of October. The discussion will include as many topics as possible but the RSGB cannot guarantee every topic will be covered. Directors will also only answer specific questions from those who attend the session at the Convention. To be part of this discussion and pose your question to the Board, book your package or day ticket to the RSGB Convention today – go to rsgb.org/convention and choose ‘Click here to book online’. Bookings close at midnight on Sunday the 8th of October. RadCom Basics Editor Lee Aldridge, G4EJB has retired. Over the past few years, Lee has been instrumental in making RadCom Basics a success. His passion for amateur radio and commitment to encouraging newcomers is infectious and has been very well received by readers. The RSGB thanks Lee for his hard work as Editor and is pleased to report that he will continue to write for RadCom Basics and provide regular technical and fault-finding articles. The new RadCom Basics Editor is Tim Hier, G5TM and the RSGB welcomes him to the role. Lee and Tim have worked together to produce the September edition of RadCom Basics. You can contact Tim with ideas or feedback for future editions via [email protected]  RSGB Members can access all issues of RadCom Basics by visiting rsgb.org/radcom-basics RSGB Director Ben Lloyd, GW4BML has taken on the challenge of activating ten summits during 12 days on the remote Scottish islands. He will climb some with his partner and fellow radio amateur Martha, and their two-year-old daughter Lyra. This SOTA – or Summits on the Air – challenge combines Ben’s favourite hobbies of amateur radio and hiking, but it also sometimes brings with it adverse weather conditions and the need to reach remote islands by kayak! Ben is hoping that by sharing his challenge he will not only inspire radio amateurs to try SOTA, but he will also encourage people who love walking and hiking to try amateur radio. You can catch up with his adventures on the RSGB social media channels and through the special playlist of videos on the RSGB YouTube channel. Go to youtube.com/theRSGB and choose the playlist called “RSGB Director Ben Lloyd, GW4BML - SOTA challenge”. The next Tonight@8 live webinar is on Monday the 2nd of October when Lee Volante, G0MTN will give a presentation aimed at newcomers to contesting. He will explore how contesting began, explain why it is rewarding and fun, and demonstrate how anyone can take part in their first contests with equipment they have today. Watch on the RSGB YouTube channel and find out more on the RSGB website at rsgb.org/webinars The RSGB QSL Bureau reports that, due to unforeseen circumstances, well-known volunteer Roy Taylor, M0RRV is retiring from his post as volunteer sub-manager for the M1 to M7 groups. The Bureau thanks Roy for his valuable service to others and is now seeking a replacement volunteer. Expressions of interest should be emailed to [email protected]  Members are requested not to send collection envelopes to this group until further notice. IARU Region 1 will hold its next General Conference from the 1st to the 4th of November 2023 in Zlatibor, Serbia. A wide range of papers and proposals are now available online and the RSGB welcomes comments on these. Topics include: general reports; organisational and budget proposals; the new HF Bandplan; VHF, UHF and SHF changes; and consideration of WRC-23, the World Radiocommunication Conference, which follows shortly afterwards. Other themes include: strategic projects and progress, accommodating digital technologies, contests, EMC and other spectrum matters. Comments should be forwarded to the relevant HF, VHF or Microwave spectrum manager, by Thursday the 12th of October, in order to allow time to finalise the RSGB position.

Using all modes on 1.2GHz frequencies, the exchange is signal report, serial number and locator.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 28th of September 2023 Another week of disrupted solar and geomagnetic conditions saw the Kp index go up and MUFs come down. A period of minor G1 geomagnetic storming was observed on Tuesday the 26th thanks to an enhanced solar wind stream containing a long-duration southward-facing Bz component. If the solar wind’s Bz magnetic field points south, it more easily couples with the Earth’s magnetic field, allowing solar plasma to flood in. The net result was a Kp index of 5.67 and visible aurora seen from the UK once again. It is worth reminding people that, at this point in the solar cycle, conditions are being governed more by the Kp index than the solar flux index. A high Kp index generally results in lower MUFs and poor HF conditions. During the week, the solar flux index was around 175, declining to 156 on Thursday the 28th. The number of solar flares also decreased as the week progressed. Next week NOAA predicts that the solar flux index will remain in the range 145 to 155, perhaps hitting 160 on the 7th. NOAA also predicts quiet geomagnetic conditions with a maximum Kp index of 2. As we said last week, at this point in the cycle solar flares and coronal mass ejections are very prevalent and hard to predict. So, do not be surprised if the Kp index goes up again. Otherwise, if it remains low, make the most of the good HF conditions that generally follow. Finally, as it is now October, we can expect another step up in HF conditions as we enter Autumn, so keep an eye on the 10m band, which should be opening up to the US and Canada in the afternoon. There are plenty of 10m beacons to listen for from 28.160 to 28.330MHz, as well as FM repeaters clustered around 29.600MHz.   And now the VHF and up propagation news Last week saw trans-equatorial openings on 50MHz with V51 Namibia reported all over the UK, as far north as Scotland around 1900UTC. On the tropo front, last week was fairly unsettled with a visit from Agnes, our first named storm of the season, which affected the north and west. The coming week is looking much more suitable for VHF radio with high pressure building over the country from Tuesday, bringing a good chance of Tropo as we go through the week. This may not be fully developed for the 144MHz UK Activity Contest on Tuesday the 3rd, but possibly starting to help lift conditions, in the south at least. The high pressure will become more widespread over the next week, but by the following weekend of the 7th and 8th of October, the 1.3GHz Trophy may have to deal with more disturbed conditions in western areas. However, conditions will still probably be good for eastern areas across the North Sea to southern Scandinavia. The meteor scatter prospects are improving as we move towards the October Draconids, which peak on the night of the 8th and 9th. Auroras have also featured recently so should remain in our checklist. Incidentally, although we are technically outside the main Sporadic-E season, Dourbes ionosonde data plotted on the Propquest website have shown occasional ‘blips’ in the critical frequency of the Sporadic-E layer, for example to 7.5MHz around 1650UTC on Wednesday the 27th of September. This would certainly be enough for 10m and perhaps even 6m chance openings. ‘If in doubt call CQ’ is the take-away message here. Moon declination goes positive on Friday the 29th of September and reaches its peak the following Thursday. This means increasing Moon elevation and lengthening Moon Windows until then. The downside being that path losses are increasing all week ahead of apogee on the 10th of October. 144MHz sky noise starts off low, increasing to 500 Kelvin next Thursday before dropping again for the weekend. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 24th September 2023

GB2RS News Sunday the 24th of September 2023 The news headlines: RSGB 2023 Convention RSGB Board appointment RSGB Trophy Manager   It is just three weeks until the RSGB 2023 Convention so grab a coffee and browse the great line-up of speakers at this year’s event. The keynote and after-dinner speaker is Colonel John Doody, who has the unique experience of having held appointments in Defence, the Intelligence Services and Industry. John will discuss his radio communication experiences across the frequency spectrum from VLF, LF, HF, VHF and SHF to satellite communications from 1965 to today. He will also talk about how amateur radio skills can help people make the most of the many career opportunities within the RF Spectrum. During the rest of the weekend, you will have a wealth of topics and speakers to choose from, ranging from DXpeditions and SOTA to 23cm, aircraft scatter, 30THz cutting-edge technology and everything else in between! AMSAT-UK is also holding its Colloquium at the RSGB Convention again. Find out more at rsgb.org/convention and book your place at this fantastic amateur radio event. The RSGB Board is pleased to announce the appointment of Richard Horton, G4AOJ as a co-opted Director to assist it in its duties until the RSGB 2024 AGM. After serving for nine years, the RSGB Trophy Manager is retiring and the Society is looking for a new volunteer for this role. Although traditionally an individual role, the tasks of the Trophy Manager could also be carried out by a small team. Working in close relationship with the three Contest Committees and the RSGB General Manager, the Trophy Manager looks after the RSGB trophies arranges for their engraving and presentation to recipients, and maintains the trophies’ history. Currently, the trophies are stored in a commercial storage facility, paid for by the RSGB, and this can be moved near to the location of the new Trophy Manager or team. If you are interested in applying for the role as an individual or a small team, please email [email protected] or you can find out more about the role on the RSGB website at rsgb.org/volunteers For the whole month of October 2023, a new event known as ‘UK Bunkers On The Air’ will be taking place. The event is now a standalone activity and this year it is dedicated to the memory of the late Chris Darlington, M0DOL. It recognises his work to establish Bunkers On The Air within the former Castles And Stately Homes On The Air, or CASHOTA, team. This is a brand new activity with a fully revamped register of former Royal Observer Corps bunkers, with more than 1,500 potential references to activate or chase. Activities are planned for the HF and VHF bands. This is a good opportunity to get out and do some portable activity before the winter closes in. Awards will be available for chasers, activators and short-wave listeners. Overseas amateurs and short-wave listeners will be very welcome to chase activators and apply for awards.

The Kp index hit 6.67 on the 19th of September, spawning reports of visible aurora from around the UK once again. This was the result of a coronal mass ejection passing Earth, which caused a period of strong G3 storming very early that morning. The ionosphere was badly affected with MUFs over a 3,000km path down below 18MHz for most of the day. By Wednesday the 20th, things began to improve and MUFs were back to 21MHz, and sometimes even 24MHz, by late morning. By Thursday the 21st, the Kp index was down to 2.67. Meanwhile, we had numerous C- and M-class solar flares to contend with as well – a total of 39 from the 18th to the 20th. So, last week was not exactly a good time for HF operations! This week, commencing today the 24th, NOAA predicts that the solar flux index will be in the range of 135 to 145 although, if the past month is anything to go by, it could easily be higher. The Kp index is forecast to be 2, apart from on the 28th and 29th when it could rise to 4. In reality, with so many sunspots, we could have a solar flare and associated coronal mass ejection at any time, so take these predictions with a pinch of salt! The good news is that we are now past the autumnal equinox, so the ionosphere is improving. Expect better worldwide HF conditions as we head towards October and November. And now the VHF and up propagation news The recent unsettled weather seems to have set a trend for us with a likely repeat process through the coming week, although there may be a few drier interludes. The next low in the sequence will soon be arriving to keep the rather unsettled theme in play. This means that rain scatter is a good choice for operators during the period. There is usually some uncertainty in such a complex pattern, and recent model runs have been alternating between a return of high pressure during the next week, with a chance of Tropo, and the continuation of lows with fronts bringing rain and showers. We are, however, in a ‘keep the lows coming’ mindset at the moment, so don’t build your hopes of Tropo too high. Such uncertainties in long lead-time forecasts are quite typical at this time of the year when ex-hurricanes can get involved in the Atlantic flow pattern and disrupt the forecasts very easily. The other modes to monitor are aurora, which has been seen recently from southern Britain, so definitely one to keep in mind, and meteor scatter, which can be productive. We are approaching the ‘busy season’ for meteors with several good showers between early October and December. However, the last week in September does not hold much promise. There are always random meteors to keep interest alive, but this week might be better used getting equipment ready for the next few months of activity. Having reached its lowest declination of the lunar month, the Moon is now beginning its slow climb back up. With the Moon out of Sagittarius, sky noise will decrease and is at its lowest mid-week. Path loss, or degradation, will be lowest on the 27th with the Moon at perigee, its closest point to Earth. The full Moon is on the 29th. Altogether, it looks like a good week for EME operations, especially if you can elevate your antenna or dish reflector. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 17th September 2023

GB2RS News Sunday the 17th of September 2023 The news headlines: RSGB Strategic Priorities RSGB 2023 Convention YOTA month The RSGB Board has chosen four strategic priorities for the Society to focus on until the 2024 AGM. These are the growth of amateur radio; membership of the RSGB; spectrum and licensing; and ensuring the continued financial stability of the Society. These priorities will set the framework for the RSGB’s activities over the coming months. Both HQ staff and volunteers across the range of RSGB teams will be involved in planning how best to implement these four priorities. Look out for further details in the coming weeks. The RSGB 2023 Convention has a great speaker programme and there are also some fantastic forums to take part in. The RSGB HF and VHF Forums will take place on Sunday, and on Saturday in conjunction with ICQPodcast, the RSGB is offering Convention attendees the chance to discuss two important topics. The first will challenge you to consider and take responsibility for the issues within amateur radio today – for example, is amateur radio just about what you like? Should someone else fix the issues you see? The second forum will focus on QRM and how both newcomers and experienced radio amateurs can sometimes feel frustrated or discouraged by on-air activities. In both forums you can discuss personal experiences, share ideas, and help to promote positive interactions with fellow radio amateurs. You will leave with a notepad full of ideas. The only way to participate in these forums is to be at the Convention, so do book your package or tickets now! Full information about the updated programme, speakers, the drop-in buildathon and the social scene are on the RSGB website at rsgb.org/convention December is Youngsters on the Air, or YOTA, month and is an exciting opportunity for you, your club, school, or social group to host an amateur radio station with the aim of getting youngsters active on the amateur bands. Once approval from Ofcom is received, the RSGB will provide access to the special callsign GB23YOTA and a full list of operating slots will be made available on QRZ.com. These slots will be first-come, first-served, so check your calendars and reserve your place as soon as possible. If you’d like to register your interest for YOTA month, or simply ask for further information, you can email Jamie, M0SDV at [email protected] The RSGB Learning Team is calling out for your help – it is looking for volunteers to get involved in the development, implementation and relaunching of the new Discovery Challenge, which is a revamp of the Individual Scheme from the Beyond Exams initiative. The team is proposing to split the activities into three levels – Explorer, Adventurer and Master. If you’d like to help out with these exciting changes, or would just like to share some ideas or feedback, you can contact Mark Burrows, 2E0SBM the Beyond Exams Coordinator at [email protected] The UK Six Metre Group’s 2023 AGM will be held via Zoom on Sunday the 8th of October from 6pm BST. The brief formal part of the meeting will be followed by a talk from Antoine, 3D2AG entitled “Extending 6m DX boundaries from the Heart of the South Pacific." Zoom details have been emailed to members. Non-members will be welcome to join the call but will not be able to vote on AGM business.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 14th of September 2023 While our terrestrial weather this week was variable, it seems our space weather was equally unsettled! We warned last week that it wouldn’t take much to cause the Kp index to rise and on Tuesday a coronal mass ejection, or CME, hit the Earth sending the Kp index to 5.67. The Bz component of the interplanetary magnetic field tipped sharply south for a long duration causing visible aurora to be seen across the north of the UK and as far south as Cornwall. This really hit HF quite hard and good signals were scarce. Unsettled radio conditions continued into Wednesday bringing the Maximum Usable Frequency, or MUF, over a 3,000km path down below 18MHz for most of the day. The Kp index was still around 3 or 4 on Thursday, but MUFs were recovering and were at around 28MHz over 3,000km by lunchtime. Next week NOAA predicts that the Solar Flux Index will start the week around 165 and then decline as the week progresses, perhaps ending at around 145 to 150. Geomagnetic conditions are forecast to be quiet, at least until the 23rd when the Kp could rise to four. But at this point in the solar cycle the risk of a solar flare, and subsequent CME, remains high every day, so watch solarham.net for up-to-date information. And finally, a new paper by NASA’s Lisa Upton and David Hathaway indicates that sunspot maximum is now forecast to be in the Autumn of 2024. They predict a maximum sunspot number of 135, plus or minus 10, which is slightly larger than Cycle 24’s maximum of 116.4, but well below the average of 179 for Solar Cycles 1 to 23. And now the VHF and up propagation news Tropo conditions are still present over southern areas today, the 17th. However, by early next week, low pressure will be a dominant force and the coming week looks very unsettled with rain and quite strong winds at times. This means that any Tropo, either across the southern North Sea or down across Biscay, will not last beyond this weekend, ending today the 17th. The unsettled low-pressure-driven weather will mean that rain scatter is a distinct possibility on some of the more active days. The other propagation modes are the usual fall-backs of meteor scatter using random meteors and aurora, which may not be too far-fetched in view of the geomagnetic activity and visible auroras experienced recently. The September Epsilon Perseids meteor shower has already peaked earlier in the month, but a few lingering meteors may give some truly random radio reflections. Last week there were indications that this normally quiet period after the August Perseids and the forthcoming October Draconids can still provide some interest for persistent meteor scatter enthusiasts. During this coming equinox week, the Moon will reach its lowest declination of the month on the 22nd and 23rd. This point also coincides with the Moon being in Sagittarius, so that sky noise will be very high. This will make moon bounce operations particularly difficult towards the end of the week. And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 7th of September 2023 The propagation team was caught out last week by two coronal mass ejections, or CMEs, that came off the edge of the Sun. The arrival of those CMEs on the 3rd of September eventually pushed the Kp index to 5.67. In its report, Spaceweather.com said that it was possible that a CME arrived on the 2nd of September, but its weak impact was masked by a chaotic stream of solar wind already blowing around Earth at the time. At this time of year, even weak CMEs can do a good job of sparking auroras as a result of the Russell-McPherron effect, which boosts geomagnetic activity around the equinoxes. So much for saying that we could expect quiet geomagnetic conditions last week! The Solar Flux Index declined to 131 but has since recovered to reach 147 on Thursday the 7th, with eight active regions visible. We had a number of M-class solar flares last week, but nothing too damaging. With the Kp index back to one on the 7th, we saw daytime MUFs rising again, heading above 24.9MHz over a 3,000km path. There were lots of Chinese and Japanese stations on 21MHz FT8 around 1100UTC on Thursday. And up on 12m FT8, even more of the same. DX stations included Thomas, KH0/KC0W on the Mariana Islands in the Pacific. While the 10m band was just about open as well, it offered slim pickings compared with the 12m band. Next week NOAA predicts that the Solar Flux Index will increase over the week to hit perhaps 155 by next weekend. Geomagnetic conditions remain variable with a Kp index of three or four forecast for the 12th to the 16th. This weekend the geomagnetic forecast is that it will be quiet although, with so many sunspots visible at the moment, it wouldn’t take much for a CME to disrupt things. As always, keep an eye on solarham.net for near real-time updates. And now the VHF and up propagation news The RSGB 144MHz Trophy produced good DX on 2m into Poland and Sweden, so we guess that Tropo performed for us this week. This spell of hot sunny weather, due to high pressure, does mean Tropo was the mode of choice for the end of this current week, ending today the 10th, especially across the North Sea. However, unsettled weather is gradually encroaching from the west, introducing some thundery rain into western areas, and this will spread east. Although the Tropo will cease, Gigahertz bands rain scatter is a likely replacement although very isolated rather than the widespread nature of a good Tropo event. It should be noted that next week is not fully determined by all models with quite a spread of outcomes. Either way, it's Tropo or rain scatter for most areas next week. It’s always possible that meteor scatter and aurora could show during this period. The early morning, around dawn, is usually the best time to look for random meteor scatter activity in the absence of any major meteor showers. For aurora, it’s best to follow the solar data from spaceweather.com to pick up early alerts and an increasing Kp index. For EME stations, Moon declination is at its highest this weekend but with apogee, the Moon’s furthest point from Earth, next Tuesday, path losses are high. 144MHz sky noise is low for most of the week except for Thursday and Friday when the Moon and Sun are very close, meaning high solar noise in the beamwidth of antennas.    And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 31st of August 2023 We had another week of relatively settled solar conditions. The Kp Index never really got above three and the Solar Flux Index flattened to be below 140. Solar flares were nominal with only minor C-class events occurring and with no Earth-directed coronal mass ejections. The solar wind speed remains low as does its density. The all-important Bz has headed south at times meaning it more easily couples to the Earth’s magnetic field, but the solar wind’s low speed and density means we have not suffered from geomagnetic disturbances. As a result, ionospheric conditions were quite good with much DX romping in on 21MHz, including Mongolia on FT8 during the afternoon. On the 10m band Vlad, 9Q2WX in the Democratic Republic of the Congo, and Robert, 9N7AA in Nepal, were both logged around lunchtime on CW. At the same time, Ravi, S79VU in the Seychelles could be heard on SSB. The Chilton and Fairford Digisondes remain down, but Dourbes remains online which is still driving propquest.co.uk Daytime maximum useable frequencies over a 3,000km path are currently peaking above 28MHz at times, although you may find 21 and 24MHz more usable. Daytime critical frequencies remain above 7MHz making the 40m band very useful around the UK. Next week, NOAA predicts that the Solar Flux Index will remain in the range of 140 to156. Geomagnetic conditions are predicted to be quiet, apart from an excursion between September the 6th to the 8th when the Kp index could rise to three. And now the VHF and up propagation news There will be some GHz bands rain scatter on offer as we end this current week, but it’s ‘all change’ by the weekend. The prospects for VHF and UHF, then, are looking very promising indeed, especially good for those out working portable in the 144MHz Trophy Contest today, the 3rd of September. After lots of uncertainty in the forecast during the last week, there is now plenty of support from the models that the high-pressure version is the favoured outcome. This should be very encouraging for 2m band contesters hoping to get some enhanced Tropo propagation. Paths across the southern North Sea to Denmark and southern Sweden look good throughout. It would also be worth looking to the south across the Channel and, for some southwestern parts of the UK, down across Biscay to Spain. There are two very useful websites that detail the expected Tropo prospects using the weather forecast model data to calculate the vertical changes in the refractive index of the air and hence Tropo. These are dxinfocentre.com and tropo.f5len.org Remember that Tropo improves as you move from HF to 2m, to 70cm and 23cm. So, give CW or SSB a try and don’t just stay on FT8 or over-crowded repeater channels during lift conditions. These enhanced Tropo conditions will likely extend well into next week, but with a chance of low pressure bringing unsettled weather back to the south by the end of next week. The daily Sporadic-E blogs have finished for this year, but the jet stream charts will still be available on propquest.co.uk and of course, random meteor scatter and chance aurora are still there if you are lucky. For EME stations, Moon declination is positive again but reaches maximum late at night initially moving to early morning as the week progresses. Last Wednesday’s perigee means path losses are still low but increasing daily. 144MHz sky noise is low, rising to moderate by next weekend. And that’s all from the propagation team this week.

Using all modes on the 2m band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 24th of August 2023 Last week saw plenty of DX being worked, thanks to quiet geomagnetic conditions and a seasonal change to a more autumnal ionosphere. Although we are still in August, there are signs that the ionosphere is moving away from its summer doldrums as its chemical composition changes to more monatomic species, which ionise more easily. Another bonus is that there has been a big reduction in the size and number of coronal holes on the Sun, which again leads to lower Kp indices. Mike, G8AXA reports that, for the first time in a long while, his Faros IBP beacon monitoring software recorded the VK6RBP beacon on 28.200MHz between 0857 and 1000UTC, via short path, just making S1 on his long wire and Yaesu FT-991A. On 21.150MHz, he also recorded hearing the ZL6B beacon between 0757 and 0909UTC up to S3. Conditions should continue to improve as we move towards September and October. Last week, the solar flux was in the 140s and 150s. The Kp index never rose above three, meaning the ionosphere was quite stable. The proton flux was also very low. FT8 on the 15m band was humming in the afternoon with the Far East and Caribbean both being workable at the same time. Next week we have active regions 3413 and 3415 rotating to be more Earth-centric. NOAA predicts that the Solar Flux Index will rise to the 160s again and the quiet geomagnetic conditions may continue with a predicted Kp index of two. So, as long as we don’t get any solar flares, or CMEs erupting from sunspot groups 3413 and 3415, we could have a good week again for HF DX. And now the VHF and up propagation news The current spell of unsettled weather looks likely to stay with us for most of next week, in fact until around Friday when there are signs of a ridge building in for next weekend, although mainly for southern areas. This could be in time for some Tropo over the weekend of the 144MHz Trophy Contest. However, the models are a bit uncertain this far out, so keep a watch for changes during the week. The remaining mode in such unsettled weather is of course rain scatter and most of the period until the end of the week should provide many opportunities. As we approach the close of the traditional Sporadic-E season, although it can still occur in any month, the activity levels are much reduced after the end of August and certainly tail off sharply after the first week in September. We are still getting the occasional flurry of activity for multi-hop paths on 10m to the Far East and the States, so don’t abandon it just yet. Remaining modes such as meteor scatter are still available via random meteor activity and there are always chances of a higher Kp index with its implications for aurora. Note that the autumn and spring months are typically a preferred time for aurora. This Saturday sees minimum Moon declination with the Moon not getting above 10 degrees elevation. It goes positive again next Friday. As the Moon’s perigee is on Wednesday, path losses are at their lowest. 144MHz sky noise is high this weekend, but falling to low levels by next Friday.    And that’s all from the propagation team this week.

The second session is from 1200 to 2359UTC on Sunday the 27th. Using RTTY only on the 160 to 10m bands, where contests are permitted, the exchange is a signal report and the four-digit year of your first licence. The Worldwide Digi DX contest runs from 1200UTC on the 26th to 1200UTC on the 27th of August. Using FT4 and FT8 on the 160 to 10m bands, where contests are permitted, the exchange is your four-character locator. Next Sunday, the 27th, the UK Microwave Group 5.7 and 10GHz Contest runs from 0600 to 1800UTC. Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 17th of August 2023 Sunspot activity continues as we head towards the solar maximum. We have had a reasonably settled Sun over the past week. The Kp index never exceeded 3.33 and was generally in the ones and twos all week. We also had no M- or X-class flares to worry about with only minor C-class events occurring. The solar flux index stayed in the 140s and 150s, only topping out at 160 on Wednesday and Thursday. So, it was not a bad week for HF propagation as we head towards the end of August. There are signs that propagation is improving due to the seasonal change in the chemistry of the F2 layer. With a move towards more monoatomic species and fewer diatomic ones, it means that it is becoming easier to ionise. Daytime critical frequencies are currently around 6 to 7MHz according to the Dourbes Digisonde, giving a maximum usable frequency over 3,000km of between 18 and 21MHz. 28MHz Sporadic-E contacts have all but finished, but don’t write the 10m band off as you may get the odd surprise. 20m still seems to be the best DX band this week, according to the Chiltern DX Club, with 17 and 15m also contributing. FO/F4FJH in French Polynesia; E51JD in the South Cook Islands; and FH4VVK in Mayotte have all been heard on 20m SSB, while 3D2AG in Fiji has been worked on 15m CW.   And now the VHF and up propagation news The fine summer-like weather has returned, at least for this weekend and up to about mid-week before it becomes more unsettled again. So, Tropo will be worth exploring, especially this weekend and during the first part of next week. Note that, in these warmer summer months, Tropo is often better overnight and early morning, especially those misty ones, but tends to decay as the ground warms in the morning sunshine. However, coastal paths often remain good throughout the day so Tropo paths across the North Sea or English Channel could be worth a look from your holiday deck chair! The Sporadic-E season is slowly coming to a close, but it is still worth a check in the evening tea-time activity window to make sure nothing is missed, and even better if you can add a morning check-up at around 1030UTC. The recent Perseids meteor shower may have added some useful meteor debris as fuel, so it is certainly not time to give up checking just yet. However, you may have to manage your expectations on the higher VHF bands. Meteor scatter is still a good bet in the tail end of the Perseids shower and the usual random meteors increase around dawn. Rain scatter is always an option in the summer months so keep a watch on weather radar displays for the brighter thundery rainfall echoes, especially later next week. There have been some interesting propagation on 50MHz down to the equatorial belt in the late evenings with D2UY in Angola working FT8 stations in an arc from the Canaries around through Northern Scotland, and the whole of the UK to Turkey with ‘Trans-equatorial sounding’ fading patterns, making decodes difficult sometimes. Moon declination goes negative again this Sunday, shortening Moon visibility windows and, as we are past apogee, path losses will fall all week. 144MHz sky noise is low to moderate until next Friday peaking at 2900 Kelvin on Saturday morning.    And that’s all from the propagation team this week.

QSL via DJ0TP’s home call and Logbook of the World. Now the contest news Today, the 13th of August, the Worked All Europe DX CW Contest ends its 24-hour run at 2359UTC. Using CW on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. On Tuesday the 15th of August, the 1.3GHz UK Activity Contest runs from 1900 to 2130UTC. Using all modes on 1.3GHz frequencies, the exchange is signal report, serial number and locator. On Thursday the 17th of August, the 70MHz UK Activity Contest runs from 1900 to 2130UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 10th of August 2023 Sunspot activity continues as we head towards the solar maximum. Or have we already gone past that point? Identifying solar maximum can only really be done in retrospect. That is after we have already had it! Solar maximum is now forecast for early to mid-2025 so we still have some way to go. Last week the Solar Flux Index declined from 176 on the 5th, to 153 on the 10th. Geomagnetic conditions were mainly settled, other than a Kp index of 6.67 on the 5th. This was due to an incoming plasma cloud from a coronal mass ejection, or CME, that left the Sun on the 2nd of August. We had not one, but two X-class flare events recently. These occurred on the 5th and the 7th. The event on the 5th was long in duration with a peak flux at 2221UTC. Luckily it was from active region 3386, which was right on the edge of the visible solar disk, so any associated CME was directed away from Earth. The second event at 2046UTC on the 7th was also from AR3386, which by now had rotated just out of view of the Earth, so again its associated CME was not Earth-directed. So, we were lucky on both counts. If this sunspot region is still active on its return, we could be in for a rough ride. Keep an eye out from around the 20th of this month when it should reappear. HF conditions have been variable, with occasional F2-layer openings on the 10m band. The 15m band has produced some good DX including 5W1SA in Samoa on FT8. The 17m band produced Roland, TR8CR in Gabon on CW for Laurie, G3UML. S79KW in Seychelles was worked by Hugh, EI2HI on 10m SSB, but it has otherwise been quite quiet. Expect more HF DX activity later next month. Next week, NOAA predicts that the Solar Flux Index will be in the low 160s, with a maximum Kp index of two. If that does pan out, we can expect fairly good HF conditions. But as always, watch out for solar flares and CMEs that can’t be predicted terribly well. A solar flare could result in a sudden ionospheric disturbance but that would be relatively short-lived. A CME, which might follow a flare in about two days, could see the MUF drop for a day or more. And now the VHF and up propagation news The brief period of high pressure around the middle of last week will be long gone by the weekend and new Atlantic lows will again dominate the UK weather. At first, this will be mainly over the northern half of Britain before moving to the western side of the country later in the week. This means that any Tropo at the end of the previous week is not here to stay. The low-pressure input will bring rain scatter propagation modes and, since we are supposedly in the summertime, the rainfall events may be quite heavy or even thundery in places, so there may be good scattering for the GHz bands. The Sporadic-E season is still simmering with a few brief moments of single hop within Europe, but also some longer multi-hop paths including to the Far East and VK on 10m. The upper air pattern of jet streams may still be able to trigger a few openings during the coming week, although it is looking much weaker than last week and possibly mainly biased towards northern areas like the Baltic and Scandinavia. Meteor scatter is one mode that should do well, especially at first with the peak of the Perseids this weekend. It can be quite interesting to monitor the 2m meteor scatter calling channel and stand outside watching for meteors, especially if it’s a bit warmer! The shower has a broad peak so should still provide activity during the coming week. Lastly, the Sun continues to offer occasional disturbed conditions with a chance of high Kp indices and possible aurora. The easiest solution is to monitor the Kp index and perhaps your favourite Scottish beacon for signs of auroral flutter. With the Moon at maximum declination this weekend, with long Moon visibility windows, it's the Microwave EME contest. Moon apogee is next Wednesday so path losses are at their highest until then. 144MHz sky noise is moderate until late Tuesday when the Sun and the Moon are close in the sky until Thursday when levels drop back to low.    And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 6th August 2023

GB2RS News Sunday the 6th of August 2023 The news headlines: Tonight@8 events on Ofcom consultation YOTA summer camp in Hungary RSGB coding resources and activities   A reminder that the second of the RSGB’s special Tonight@8 events on the Ofcom Consultation will take place on Monday the 7th of August. This time the focus will be on Foundation and Intermediate topics including callsign and exam changes, as well as the Consultation clauses that might lead to new opportunities for outreach activities for everyone. The Consultation also affects anyone who isn’t currently licensed but is thinking about taking their exams in the next couple of years. After a short introduction, a panel of RSGB experts will answer your questions on this important Ofcom Consultation. For this event, you can submit a question in advance by 6pm today, Sunday the 6th of August. Send a brief question with your name and callsign to [email protected] You can also ask a question on the night via the live chat. This is an important event – do join it live on Monday via the RSGB YouTube channel. To find out more about the Consultation and this event go to the RSGB website at rsgb.org/licencereview You can watch a recording of the first Tonight@8 event on the Ofcom Consultation via the RSGB’s YouTube channel. The 2023 Youngsters on the Air, or YOTA, summer camp in Hungary began this weekend and lasts for a week. The four young people representing the RSGB are Alexander Du Rose, 2E0FMZ who is the Team Leader; Henry-James Robinson, M7HJR; Hannah Lee, M7YYQ; and Jake Saul, M7JNS. Each day, they will be sharing news of the activities they enjoy and the amateur radio skills they learn. Take a look at their updates over the coming week on the RSGB website at rsgb.org/yota-hungary and read their fuller report in the October issue of RadCom. As part of the RSGB’s commitment to encourage youngsters into amateur radio and to support lifelong learning, the Society is providing resources and creating coding activities for people to get involved in throughout the month of September 2023. From the BBC Micro:bit to Node-RED and GNU Radio, there are some great activities you could try yourself with your club or arrange at a local school or community group. If you are an experienced coder, the Society would like you to support this initiative by passing on your enthusiasm to a local school or STEM club with the help of the suggested activities. If you are new to coding and have no idea what Python is or a Raspberry Pi, then the activities will set you on the path of discovery! Find out more on the RSGB website at rsgb.org/coding. If you would like to get involved, contact ESRG member John Hislop, G7OHO via [email protected] The RSGB has responded to an Ofcom consultation on licensing Enhanced Long-Range Navigation, or eLoran, systems. This would use a new network of 400kW EIRP transmissions at around 90 to 110kHz to provide an alternative to GPS for Position, Navigation and Timing, or PNT. The response, which can be found on the RSGB’s Spectrum Forum webpages, focussed on the high levels of out-of-band emissions that would affect the weak signal 136kHz amateur allocation, as well as transparency on transmitter licensing. The consultation response can be viewed by visiting thersgb.org/go/sfpapers The ARRL, the national association for amateur radio in the USA, has filed comments against a proposal that would introduce high-power digital communications to the shortwave spectrum that, in many instances, is immediately adjacent to the amateur HF bands. You can read the full story, which is titled ‘ARRL Files Comments Against “Seriously Flawed” HF Rules Petition’, via arrl.org/news And now for details of rallies and events Part 1 of the British Amateur Television Club’s Convention for Amateur TV 2023, or CAT 23, is taking place today, Sunday the 6th of August, at Midland Air Museum, Coventry.

Using all modes on the 6m band, the exchange is signal report, serial number and locator.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 3rd of August 2023 The Sun continued to be very active over the last week with a large number of sunspots, numerous C- and M-class flares, and a coronal mass ejection or two. A coronal mass ejection is predicted to hit Earth this weekend, which could see the Kp index rise, but this is not expected to be too extensive. Active region 3380 expanded in both size and magnetic complexity, firing off numerous solar flares. Luckily it is now rotating out of view so is no longer a threat. The Solar Flux Index remained above 170 all week with a sunspot number of 135 on Thursday. Don’t forget that this doesn’t mean there were 135 sunspots, as each group counts ten towards the total. Three sunspots in three groups equals thirty plus three, or thirty-three. Geomagnetic conditions were mixed with one period giving a Kp index of four, and many when it was over three. The main DX being chased this week wasn’t actually too far away. The 1A0C station at the Sovereign Military Order of Malta, which confusingly is actually in Rome, gave amateurs plenty of opportunity to add to their band slot totals. The station was raising money for humanitarian charitable projects and was easy to work from the UK.  Next week NOAA’s Space Weather Prediction Centre thinks the Solar Flux Index will remain in the 165 to 170 region. The Kp index shouldn’t rise above three, although that rather depends on whether we have any coronal mass ejections. There are also signs that we are starting to leave the Summer HF doldrums. MUFs over a 3,000km path have occasionally gone over 28MHz at times. But we are still a long way from Autumn HF conditions, despite the weather!   And now the VHF and up propagation news The unsettled weather is here for a little longer, but there may be an end in sight as we move through the second half of next week.  To begin, there will be areas of low pressure in control bringing rain or showers and more rain scatter on the GHz bands. Midweek, the high edges in from the west and remains close to the southeast into the next weekend, but lows and weather fronts will probably return to the western areas by the end of the week. Nonetheless, this should be a period of Tropo for many areas, if only temporarily for western areas. Meteor scatter could be good with a steady advance towards the peak of the Perseids on the 12th and 13th of August. It might even be warm enough to stand outside in the southeast and listen to the pings while watching the evening sky for meteor trails! Aurora can’t be discounted either should the Kp index show higher values than, say, 5 and there have been a number of auroral contacts reported by Nordic stations over the last week. In August there is still some Sporadic-E to be had as luckily the jet stream pattern is still quite busy giving ample triggers for Sporadic-E due to the turbulence they create. As often mentioned, a good time to check, if you are a busy person, is around teatime or late afternoon. Moon declination goes positive on Saturday so Moon visibility windows will lengthen throughout the week. We are past perigee so path losses are rising again. 144MHz sky noise is low but rising, reaching moderate levels next weekend. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 30th July 2023

GB2RS News Sunday the 30th of July 2023 The news headlines: • Tonight@8 events on the Ofcom amateur radio consultation • Bar-coded stamps • GB2RS in Morse code The RSGB is holding two special live Tonight@8 events focused on the Ofcom amateur radio consultation, and it encourages all radio amateurs to take part. On Monday the 31st of July the session will look at contests, operating and callsign policy, in an event that might be of particular interest to Full licensees. On Monday the 7th of August, the focus will be on Foundation and Intermediate topics including callsign and exam changes, as well as the Consultation clauses that might lead to new opportunities for outreach activities for everyone. Instead of the usual webinar style, these events will be forums where, after a short introduction, a panel of RSGB experts will answer your questions. Questions can be submitted on the night of the event via live chat, or you can send in a question in advance. Advance questions can be by email or a short, clear video of you asking your question. In either case, please keep the question short and include your name and callsign. Send questions, by 12 noon on the Friday before the event, to [email protected] and find out more about the events and the consultation on the RSGB website at rsgb.org/licencereview  From tomorrow, the 31st of July, you should not apply non-bar-coded stamps with Her late Majesty Queen Elizabeth II’s image to any mail. In doing so the sender or recipient may have to pay a surcharge. This news is highlighted to radio amateurs who use stamped-addressed QSL card envelopes. Please ensure all stamped-addressed envelopes have valid bar-coded stamps on them. This only applies to stamps with Her late Majesty Queen Elizabeth II’s image on them and does not apply to stamps which have other pictures on them. These can continue to be used. Royal Mail will exchange all non-barcoded stamps with new bar-coded ones for free. To do this, download a form from the Royal Mail website, complete it and include it alongside the stamps that are being returned.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 27th of July 2023 It was a mixed bag last week with periods of settled conditions, but two periods when the Kp index was above four. These unsettled geomagnetic conditions impacted HF, subduing signals and generally not helping at all. The cause was a coronal mass ejection, or CME, that passed Earth late on Tuesday the 25th of July. This triggered a minor G1 geomagnetic storm with the solar wind speed above 500km/s and the Bz component of the interplanetary magnetic field pointing south.  By the early hours of Thursday morning, the Kp index was down to 2.33, but there was talk of another CME threatening to push it up again.  We ‘dodged a bullet’ on the 24th of July when a large halo CME was observed leaving the Sun. It was so powerful that, despite taking place on the other side of the Sun, energetic proton levels streamed past Earth. By Wednesday lunchtime things were back to normal. By Thursday there were ten active regions visible on the Sun, with a solar flux of 167. Daytime HF conditions are still relatively poor, although the evenings are beginning to show an improvement. We probably won’t see a return to excellent HF conditions until September or October. Having said that, at 1230UTC on Thursday, there were openings on 15m FT8 to Japan, Australia, Indonesia, Puerto Rico, Cuba and Anguilla, despite the predicted MUF over 3,000km being around 19MHz. In other words, make sure you actually listen to the bands! Next week NOAA predicts that the Solar Flux Index will be in the range of 155 to 170. The Kp index is forecast to be around two. There may be a blip on Wednesday the 3rd of August when it is forecast to rise to three.  As always, this is likely to change if we get more solar flares and associated CMEs. And now the VHF and up propagation news The coming week is likely to continue its unsettled theme although, unlike last week, this time we may find a temporary ridge of high pressure building over southern England at the end of the week.   It’s some way off and much could change before we get there, but there is a hint of some Tropo next Friday, perhaps lasting into the Saturday afternoon for the 144MHz Low Power Contest.  The rest of this week and much of next will, however, stay firmly in the unsettled pattern with just rain scatter to console us. The Sporadic-E season often provides activity on the 6m band into the first week of September, so plenty of time to look for those chance QSOs. Last week saw a huge opening to Japan and a smaller opening to North America so there is still plenty to look for.  The current spell of unsettled weather is driven by a strong jet stream across the Atlantic into northern Europe and maybe a positive sign for Sporadic-E paths that cross it, say to Iberia, round through Italy to the Balkans. Other modes are relatively-low probability when compared with Sporadic-E, but the disturbed solar conditions could make Aurora a contender on those occasions when the Kp index is above five. Meteor scatter activity continues to increase as we head into the August Perseids, which peak around the 12th and 13th of August. The Moon reaches minimum declination on Sunday, becoming positive again late next Saturday so there will be short Moon windows early in the week. Perigee is on Wednesday so path losses are low. 144MHz sky noise is high this coming weekend turning low late Monday. And that’s all from the propagation team this week.

Next weekend is the RSGB IOTA, or Islands On The Air, Contest. It runs from 1200UTC on the 29th to 1200UTC on the 30th of July. Using CW and SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report, serial number and IOTA reference. Please note that the Worked All Britain 144MHz Low Power Contest which was due to be held on Saturday the 29th of July has been moved to Saturday the 5th of August. A further announcement is expected next week. Next Sunday, the 30th of July, the UK Microwave Group 5.7 and 10GHz Contest runs from 0600 to 1800UTC. Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 20th of July 2023 The Sun continues to be peppered with spots with a solar flux index of 189 on Thursday the 20th. However, sunspots can bring solar flares and Coronal Mass Ejections, or CMEs, which can be detrimental to good HF conditions. We have been relatively lucky over the last week as the flares have mostly been minor C-class and a few M-class events. There have been no X-class flares, so ionospheric disturbances have been minor. A large CME observed from active region 3363 is expected to mostly miss our planet. But the edge of the plasma cloud was still forecast to deliver a glancing blow to our geomagnetic field on Thursday the 20th of July. A Polar Cap Absorption, or PCA, event was also in progress from the morning of Monday the 17th of July. This was caused by the proton flux rapidly increasing and affecting HF paths over the poles. The proton flux is gradually decreasing but may still have a detrimental effect for a while yet. Region 3363, which was massive, has now disappeared behind the southwest limb and will no longer be a threat. That is, at least until its return in about two weeks’ time. It will be interesting to see how big it is on its return. Other than the Kp index hitting 4.67 on the 16th and 17th, geomagnetic conditions have been quiet with the Kp index at one or two over the past few days, which means HF conditions have been quite good. Daytime MUFs over a 3,000km path have been consistently above 18MHz and often above 21MHz at times. Nighttime MUFs over the same path have been higher than 14MHz, and often 18MHz, at least during the first part of the night. This means that if you hear signals on 24 or 28MHz the likelihood is that they are due to Sporadic-E propagation. Next week NOAA predicts that the Solar Flux Index will remain at about 160 to 170. It is also predicting a Kp index of two all week. If that happens, we can probably expect good HF conditions for this time of year. However, with this many sunspots, there is always the strong risk of solar flares and CMEs. So, keep an eye on solarham.net for real-time conditions. And now the VHF and up propagation news The continuing spell of unsettled weather will stay with us for the coming week, so any signs of Tropo will be very limited indeed. This means that rain scatter will once again be a predominant propagation mode for those equipped on the GHz bands to use it. Higher temperatures in summer mean strong convective cells, like thunderstorms, and better reflectivity from the larger raindrops, which can be held aloft by the stronger updrafts in the storm clouds. The reflectivity depends upon the 6th power of the diameter of the raindrop and the number of drops in the beam, so even a small increase in drop size gives a big increase in reflectivity. Sporadic-E remains in play for a good while yet, so stay alert to cluster reports and, in particular, 10m and 6m beacons. If time is limited, check 1600 to 1700UTC to gain maximum benefit. The usual other modes are still possibilities, of course. Starting with Aurora, in view of the recently disturbed solar conditions, you should monitor the Kp index for large values above say Kp=5.  Secondly, the Perseids meteor shower will peak between the 12th and 13th of August, but evidence of meteor material from the Perseids is already appearing. Officially, the shower starts to appear from around the 17th of July. The 50MHz and 144MHz bands have already produced some very short-lived bursts of FT8 signals that may be due to meteors.  The Delta Aquariids may also be responsible for these very sporadic bursts. As we move towards the Perseids peak you should expect an increasing number of bursts. As the Moon begins its monthly descent towards minimum declination on the 29th, path loss will decrease. However, the Moon will be close to Sagittarius A on the 28th, leading to very high noise. This will be prevalent on the lower VHF bands. And that’s all from the propagation team this week.

They are operating using CW, SSB and FT8 on the 80 to 6m bands. QSL via Club Log's OQRS. Now the contest news Today, Sunday the 16th, the International Low Power Contest runs from 0900 to 1600UTC. Using CW on the 80, 40 and 20m bands, the exchange is signal report, serial number and TX power. On Monday the 17th of July, the RSGB FT4 Contest runs from 1900 to 2030UTC. Using FT4 on the 80, 40 and 20m bands, the exchange is your report. On Tuesday the 18th of July, the 1.3GHz UK Activity Contest runs from 1900 to 2130UTC. Using all modes on 1.3GHz frequencies, the exchange is signal report, serial number and locator. On Thursday the 20th of July, the 70MHz UK Activity Contest runs from 1900 to 2130UTC. Using all modes on the 4m band, the exchange is signal report, serial number and locator.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 13th of July 2023 Last week saw the arrival of one of the biggest sunspots of this cycle. Active region 3363 could swallow the Earth four times over. It is a source of M-class flares, but at the time of writing hasn’t produced any X-class events. A new sunspot region 3372 has just rotated into view and has also been the source of eight M-class flares, one of which may have caused a coronal mass ejection that could give a glancing blow to the Earth this weekend – watch this one for more activity as it rotates into an Earth-facing position. Meanwhile, the Solar Flux Index has been hovering around the 200 mark, meaning daytime MUFs over a 3,000km path are around 21MHz, sometimes slightly lower. At night this falls to around 14 to 18MHz so don’t write off HF once the sun sets. Next week, NOAA’s Space Weather Prediction Centre has the Solar Flux Index around 175. While we have been lucky that Earth has not been subjected to too much geomagnetic disruption, after any disturbance across the weekend, the Space Weather Prediction Centre has forecast that the Kp index will be around two again all week. So it may be ideal for DX, like Silvano 9Q1AA/9Q1ZZ in the Democratic Republic of the Congo, who has been active on the 10 and 15m bands recently. Or the KH8RRC DXpedition to American Samoa which is active until the 18th. Remember, there is DX to be worked – you’ve just got to pick the right band and time. And now the VHF and up propagation news The predominant theme this week is driven by low pressure systems, meaning further days of heavy rain or thundery showers and a distinct lack of Tropo from areas of high pressure. However, there is a split in the different models' view for southern Britain later in the coming week in which some try to build a ridge across southern UK and France from the Azores high. Check the forecast charts from Wednesday onwards to see which version ‘wins’. In the meantime, the heavy rain will continue the recent good run of rainscatter on the GHz bands. Sporadic-E will probably continue to be a feature on most days somewhere in Europe. Last Wednesday night saw another good opening to Newfoundland. Remember that there are plenty of online clusters and map plots showing where the focus of activity is located. Each day a blog is published on propquest.co.uk detailing the locations of likely Sporadic-E activity, based upon the positions of various weather features suspected of being responsible for the location of Sporadic-E patches. The recent behaviour of the Sun has regularly affected the prospects for VHF propagation by interaction with the Earth’s magnetic field giving a high Kp index, above five, which can be a sign of auroral conditions. A high Kp index is potentially a bad thing for Sporadic-E prospects, some operators suggesting that it is possible that solar flare activity may also be a negative influence on Sporadic-E. Meteor scatter prospects continue to improve due to two broad-peaked showers coming up later in the month. This weekend sees maximum Moon declination but losses are high as we approach apogee next Thursday. 144MHz sky noise is moderate until Monday when the Sun is close to the Moon for the whole day’s pass, lasting until 9am on Tuesday. After this, sky noise is low for the rest of the week.   And that’s all from the propagation team this week

Using CW on the 80, 40 and 20m bands, the exchange is signal report, serial number and TX power.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 6th of July 2023 NOAA’s prediction that the Solar Flux Index, or SFI, would decline last week didn’t come to fruition. In fact, the SFI stayed in the 160s and 170s until Thursday, when it declined to 155. The Sun produced more than 160 sunspots in June, the highest monthly number in more than two decades. This has led some newspapers to run more doom and gloom stories about solar Armageddon, while we amateurs look forward to some F2-layer DX! Unfortunately, more sunspots do mean more chance of solar flares and coronal mass ejections, but we have to take the rough with the smooth. As an example, we had an X1-class solar flare on the 2nd of June. This occurred at 2314UTC so didn’t affect the UK, but did cause an R3 radio blackout over the west coast of the USA and Pacific. Otherwise, there is still DX to be bagged for well-equipped stations, such as Eric, FP/KV1J on St Pierre and Miquelon islands on 12m FT8, and Marek, FH4VVK, on Mayotte island, on 10m FT8. Other DX worked this week by CDXC members includes the 4W6RU DXpedition on Timor Leste on various bands; Robert, 9N7AA in Nepal on 12m FT4; and V31XX in Belize on 20m CW. Next week, the Space Weather Prediction Centre has the SFI at 155, rising to 175 by the end of the week. Unfortunately, the Kp index is forecast to rise to four over the weekend, possibly due to a large Earth-facing coronal hole, and again up to Kp five on the 12th and 13th. If it happens, expect noisy bands and a decline in the maximum usable frequency. As always, we encourage you to get on the HF bands, in the evening, nighttime and especially around dawn, which is when a lot of HF DX is being worked. And now the VHF and up propagation news Low pressure dominates the whole weather pattern this coming week, driven by an active meandering jet stream across the Atlantic. This provides several regions where the turbulence, generated on the edge of these strong winds up at 10km, can propagate upwards to trigger Sporadic-E propagation at about 110km height in the E region. So, unsurprisingly, Sporadic-E will feature as a ‘go-to mode’ for the coming week. Typically, single-hop paths within Europe will produce very strong signals, whereas multi-hop paths, for example across the Atlantic, will require several such refraction points from Sporadic-E patches, plus intervening reflections from the sea surface, and will have much higher losses. These will usually be weak signals and probably very fleeting in view of the complex geometry of such paths. Tropo need not concern us this week, but rain scatter is worth a look since the unsettled weather will provide several heavy rainfall events in some areas. Look for the brighter echoes on the rainfall radar displays, especially those associated with thunderstorms. Random meteors could be useful in the early morning hours. We also have the start of two showers, Alpha Capricornids and Delta Aquarids, during next week, which don’t actually reach a peak until the end of July. So prospects for meteor scatter and Sporadic-E propagation are improving this month. The aurora chances may be reasonable initially in view of the recent coronal hole transition, so keep an eye on the Kp index. Moon declination goes positive on Sunday so there will be lengthening Moon windows. Path losses are currently low but will rise all week. 144MHz sky noise is low to moderate all week. And that’s all from the propagation team this week.

Using CW and SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and ITU zone. The UK is in zone 27.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 29th of June 2023 The solar flux index stayed in the 150s and 160s last week, which is good news for HF propagation. From a flare and CME perspective, we have been lucky in that we have only had a few solar flares, all of which have been C- or M-class. As a result, the Kp index has remained fairly low, being in the range of one to three after the rise to a Kp of five on the 25th due to the solar wind’s magnetic field, or Bz, tipping south. We are, however, still in the summer doldrums, so daytime DX is limited thanks to D-layer absorption. We still recommend checking the bands at night as the MUF over 3,000km is still exceeding 14MHz and often reaching 18MHz at times. During the day Sporadic-E may still keep you entertained on the higher HF bands.   Daytime critical frequencies are around 5.2 to 6.7MHz according to the Dourbes ionosonde, which means you may find close-in contacts tricky on the 40m band at times, whereas more DX distances are still fine. Near vertical incidence skywave or NVIS, 40m signals may not be returned to Earth with that critical frequency. Looking ahead, active sunspot region 3354 was pointing directly at the Earth on Thursday but has so far been behaving itself with mostly C-class flare events. It is still the most likely candidate for a coronal mass ejection, or CME, over the weekend. Next week the Space Weather Prediction Centre has the Solar Flux Index declining to 130 before picking up later in the week to perhaps 145. The Kp index should remain around two unless we have a CME which could see it rising to five with the attendant lowering of the MUF. Meanwhile, you can get an idea of the best times to work various parts of the world by using the free Proppy software at soundbytes.asia/proppy or via VOACAP.com   And now the VHF and up propagation news The next week or so looks likely to continue in a very unsettled theme with low pressure residing over Scandinavia for much of the time and producing a west or north-westerly pattern over the UK. This will mean that tropo propagation will not be a large part of our operations during the period ahead. On the other hand, the frequent spells of fronts with prolonged rain or heavy summer showers will make rain-scatter modes a good use of time on the GHz bands. Talking of scatter modes, we are not in a major meteor shower at present, so random meteors are a good fail-safe although it can entail spending a lot of time in the process. The solar conditions, as previously mentioned, can be unsettled at the moment, and thus there is a potential for radio aurora if the Kp index goes above seven or so, even though daylight makes visible events unlikely at this time of the year. Lastly, the Sporadic-E situation is still our primary focus as we move into July. Days with good jet stream activity over Europe are good signs, whereas a high Kp index or solar flares are generally not so good. Of course, there are many other parameters involved and one of the critical components is likely to be the random meteor count which shows how much meteor debris might be available to make the Sporadic-E patches. In a roundabout way, if you monitor the meteor pings you might get a feel for how the Sporadic-E prospects are stacking up. The Moon declination is negative all week so there will be short Moon windows. Tuesday’s perigee means that path losses are at their lowest for the month. 144MHz sky noise is high this weekend but falling back to low levels by the end of the week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for June 25th 2023

GB2RS News Sunday the 25th of June 2023 The news headlines: Ofcom consultation on updating the amateur radio licensing framework RSGB Tonight@8 webinar ‘Fly Your Satellite!’ programme An Ofcom consultation titled “Updating the amateur radio licensing framework” opened on Friday the 23rd of June 2023. According to Ofcom, the proposals set out in the consultation aim to “provide greater operating freedom for radio amateurs; and make the process of getting and using a licence simpler, clearer and more responsive.” The closing date for responses is the 4th of September 2023. All radio amateurs are strongly encouraged to read the consultation via Ofcom’s website directly. You can also find the consultation by visiting rsgb.org/licencereview and clicking the Ofcom logo. The RSGB will provide guidance on how to respond to the consultation via the same web page in due course.  The next RSGB live Tonight@8 webinar will take place at 8pm on Monday the 3rd of July, with Eric P. Nichols, KL7AJ presenting “Receiving antennas are different”. Eric, who has written numerous amateur radio and electronics articles over the past 30 years, says that almost every ham radio station can benefit from a separate receiving antenna. Effective receiving antennas are optimised for best signal-to-noise ratio, not necessarily the greatest gain. Tune in to the RSGB YouTube channel or special BATC channel to hear Eric discuss the countless interesting means of building high signal-to-noise ratio receiving antennas. You can find out more at rsgb.org/webinars The ‘Fly Your Satellite!’ programme, initiated by the European Space Agency, presents an exciting challenge for radio amateurs and space enthusiasts worldwide to establish communication via the LEDSAT CubeSat digipeater. This unique opportunity invites participants to connect with the ESA Education Office ESTEC Ground Station in the Netherlands through the satellite digipeater, with a chance to win a special prize – a custom QSL card issued by the ESA Education Office and the LEDSAT team. Running from the 26th of June to the 30th of July, this challenge offers an exciting chance for radio enthusiasts to engage with space technology and demonstrate their communication skills. For more information go to the European Space Agency website at esa.int and search for “Connect and communicate with a satellite via the LEDSAT Digipeater Challenge.” It was with profound shock and sadness that the RSGB learnt of the untimely loss, at the age of 49, of Mr Alexandre ‘Sasha’ Kholod, Chairman of the CEPT WRC-23 Conference Preparatory Group. Alex was head of international frequency planning for the Swiss regulator and was widely respected and influential in CEPT and ITU. Of note to amateurs is that he chaired CEPT Project Team C which led to the successful ITU Region 1 50MHz allocation for the amateur service at World Radio Conference 19 in November 2019. His warm and professional personality will be sadly missed.   And now for details of rallies and events The Newbury Radio Rally is taking place today, Sunday the 25th of June.

On Sunday the 2nd of July, the 3rd 144MHz Backpackers Contest runs from 1100 to 1500UTC. Using all modes on the 2m band, the exchange is signal report, serial number and locator.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 22nd of June 2023 We had yet another week of high solar flux, plenty of sunspots, but also a major solar flare. The Solar Flux Index reached 180 on the 20th of June with a massive spread of sunspots across both solar hemispheres. But an X-class solar flare erupted on the same day. This was only just X-class though, as at X1.1 it barely hit the requirements. Luckily, its associated coronal mass ejection was directed away from Earth. We passed the summer solstice this week so are now heading towards Autumn. Don’t worry too much, though, as there is plenty of summer left, complete with its lower daytime maximum usable frequencies and high levels of D-layer absorption. Fortunately, multi-hop Sporadic-E is also bringing occasional DX on the higher bands. As we pointed out last week, nighttime MUFs remain high, partly due to seasonal norms and partly due to the high solar flux. There were reports this week of 15m CW still being open at 3.30 am local time, when Paul, MM0ZBH worked the VP6A DXpedition on Ducie Island. There have also been many reports of VP6A being worked on the 80m band at around 0800 UTC. Next week the Space Weather Prediction Centre puts the Solar Flux Index at around 165 to 180 again. We can expect unsettled geomagnetic conditions once again around the 27th and 28th of this month. Daytime F-layer MUFs over a 3,000km path are generally around 21MHz, but there are occasional surprises. Sporadic-E still dominates on the 10m band. At night, MUFs over 3,000km are often around 14 to 18MHz, again with some surprises at times. And now the VHF and up propagation news After a slow change to a more summer-like pattern of showers and sunshine with occasional fronts in the last week, it does seem like it's a continuation for the coming week. This means further opportunity for rain scatter on the GHz bands and with a reasonable chance of tracking the storms with any of the online weather radars. There will be a tendency for higher pressure close to southern Britain with possible Tropo, which will extend south across Biscay to northern Spain or farther south towards the Canaries and perhaps beyond. It may even offer paths east across the southern North Sea towards Denmark. There have been some reasonable Sporadic-E paths within Europe and beyond to the Americas. Paths have also opened eastwards to the Far East or Middle East and there is no reason not to expect similar for the coming week. As next week progresses, the jet stream distribution may favour paths to Scandinavia and the Baltic, plus across the Atlantic to the States. The recent unsettled solar conditions may affect the prospects for Sporadic-E propagation if the Kp index becomes too high, but on the plus side it could then be worth checking for aurora. Don’t forget that random meteors can provide a few chance QSOs using meteor scatter propagation and there have been audible meteor ‘pings’ on some Sporadic-E QSOs recently, so they do exist! Moon declination goes negative again on Monday – so shortening Moon windows. Path losses will fall all week, and 144MHz sky noise is low to moderate until next weekend when it reaches more than 2500 Kelvin on Sunday. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for June 18th 2023

GB2RS News Sunday the 18th of June 2023 The news headlines: His late Majesty, King Hussein of Jordan’s UK amateur radio equipment Coding and amateur radio RSGB Convention 2022 presentations   The Radio Society of Great Britain is delighted to announce that Her Majesty Queen Noor of Jordan has chosen to donate the UK amateur radio equipment of His late Majesty, King Hussein of Jordan to the Society. His Majesty was a great ambassador for amateur radio and, whenever his official duties allowed him, his radio callsign JY1 could be heard on the amateur bands. His Majesty always operated modestly, never announcing himself as King Hussein, always just ‘Hussein from Jordan’. A permanent display is being organised at the RSGB National Radio Centre so that the equipment can be used to help inspire people to get involved in amateur radio and promote communication, friendship and understanding throughout the many countries and cultures of the world. The RSGB extends its thanks to Her Majesty for this generous donation. National Coding Week has been run for many years in the third week of September. Coding is used increasingly in amateur radio, and the BBC Micro:bit and the Arduino have made it easier for radio amateurs of all ages to discover more about this. As part of its commitment to encourage youngsters into amateur radio and to support lifelong learning, the RSGB will be providing resources and creating coding activities for people to get involved in throughout the month of September. The Society is keen to hear from volunteers who have ideas for this initiative and would like to be part of it. Further details will follow but, if you’re interested, in the first instance please contact Exam and Syllabus Review Group member John Hislop, G7OHO via [email protected] The RSGB has released two further Convention 2022 presentations. In the first, Noel Matthews, G8GTZ provides an introduction to the challenges of operating on 122GHz and gives an overview of the VK3CV-designed transverter boards which have put operation within the reach of amateurs without requiring advanced electronic and mechanical engineering skills. He tells the story of how he and Dave, G1EHF used the boards to work up from their first QSO over 2km to breaking the UK record for 122GHz at 36.5kms. Secondly, in a presentation called “HF propagation – what do the numbers mean?” RSGB Propagation Studies Committee Chair Steve Nichols, G0KYA unravels what terms such as Solar flux index, SSN, A and K index, and Solar Wind Speed mean and explains how to find the best HF conditions. You can watch both on the RSGB YouTube channel at youtube.com/theRSGB After serving for nine years, the RSGB Trophy Manager is retiring and the Society is looking for a new volunteer for this role. The position is part of the RSGB Volunteer Leadership Team, reporting to the Board. Working in close relationship with the three Contest Committees and the RSGB General Manager, the Trophy Manager looks after the RSGB’s trophies arranges for their engraving and presentation to recipients and maintains the trophies’ history. If you are interested in applying for the role or would like to find out more, please email [email protected] The G-QRP Club is running a fun event called the Summer Sizzler from Saturday the 17th to Sunday the 25th of June. This is not a contest, rather it is a relaxed on-air QRP event. It is an ideal opportunity to meet and greet new and old friends, to test your latest homebrew creations and to fill the bands with friendly QRP activity. The best logbook for the event will win the inaugural GM3OXX trophy. This will be decided upon by adjudicators and will not necessarily be awarded to the entrant with the most contacts. Unusual or remarkable logbooks have just as much chance of winning.

Using all modes on the 6m band, the exchange is signal report, serial number and locator. On Sunday the 25th of June, the UK Microwave Group 5.7 and 10GHz Contest runs from 0600 to 1800UTC. Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 15th of June 2023 We had another week of sound HF propagation, helped by relatively quiet geomagnetic conditions, a lack of bad solar flares, and some good multi-hop Sporadic-E openings. The Kp index never rose above three and was mostly ones and twos. This was no doubt helped by no M-class or higher solar flares and no Earth-directed coronal mass ejections. A large filament did break away from the Sun on the 12th of June, but luckily it was directed away from Earth. The solar flux index declined to the mid-140s after reaching 172 on the 6th of June. Paul, GM4ULS sent in an impressive log of 10m SSB contacts with Brazil, Argentina, Chile and Uruguay. These were mostly during the late afternoon although Paul says the openings often started around noon. F2-layer propagation was the first thought, but closer analysis suggests that these were more likely to be multi-hop Sporadic-E. If these contacts die out as we progress through the summer that should confirm that they were multi-hop Sporadic-E. Paul does have one tip. He listens to 27.555MHz, which is the SSB CB calling frequency. If he hears activity there he then fires up on the 10m band. Other DX this week has included VP6A on Ducie Island in the South Pacific. This DXpedition should be active until the 26th of June, so there is still plenty of time to work them. 8Q7KB in the Maldives should also be on until the 21st of June. Next week, the Space Weather Prediction Centre thinks the Solar Flux Index will start the week at around 150, rising to 170 as the week progresses. After a geomagnetic disturbance this weekend that may see the Kp index rise to four, and is likely caused by a coronal hole on the Sun’s surface, we may expect quieter conditions next week with a maximum Kp index of two.   And now the VHF and up propagation news There has been some excellent Sporadic-E and super Tropo propagation during recent UK Activity Contest events. This is high-season for Sporadic-E, so it's worth a few notes to sharpen your DX potential. There are often two main 'windows' of activity: mid-morning and late afternoon or early evening. For early risers, there can be a surprise ‘window’ of activity around 0600 to 0700UTC on some days and this is particularly useful for paths across the pole to Japan and the Pacific. The tendency is for openings to migrate westwards. Paths across Eastern Europe will be replaced by new paths to Italy or even Iberia as the particular event ‘window’ migrates west. In this peak season the Sporadic-E operating ‘windows’ may almost merge into one continuous activity period, especially on the lower bands such as 10m and 6m. As paths to Portugal fade, the new cycle may be starting with paths to Scandinavia and the Baltic. Multi-hop paths will be weaker than single-hop, and often more fleeting due to the complex geometry required, making the slower data modes frustrating. Add this to frequency spreading, and sometimes slick, fast CW can be the best mode if you can find the activity. The prolonged high pressure has provided some very good Tropo paths, particularly across the North Sea to Scandinavia. This may not be so reliable in the coming week as low-pressure moves in and offers heavy thundery showers as a source of rain scatter for GHz operators.  Meteor scatter and aurora are always possible, but Sporadic-E will probably be too much of a distraction. Sunday sees peak Moon declination but with apogee this coming Thursday, path losses will be at their highest.  144MHz sky noise is moderate until Saturday afternoon when the Sun and Moon are very close in the sky, spoiling the weekend for VHF EME. This “close to eclipse” condition persists until Sunday night after which noise levels are low to moderate for the rest of the week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for June 11th 2023

GB2RS News Sunday the 11th of June 2023 The news headlines: RSGB President's IRTS speech Contest group map Distance learning for Full licence exam   RSGB President, John McCullagh, GI4BWM received a warm welcome when he attended the IRTS AGM Gala Dinner recently. He talked about the challenges faced by national societies, as well as the success of the RSGB’s Tonight@8 live webinars and online exams, which were introduced during the pandemic. John also stressed the importance of engaging young people in amateur radio, through the Society’s work with schools and universities. He is featured on page 10 of the June issue of Ham Radio Ireland Magazine. As part of the RSGB’s new Club Finder facilities, the Society has launched an online map that shows affiliated contest-only clubs and groups. If you’d like to get involved in a group, you can use the map to search locally and more widely. Depending on the club entry you will be able to see which contests they participate in as well as their contact and website information. If you are part of an RSGB-affiliated contest group or club, please check your details and, if they need updating, log into the RSGB members’ portal. New information will be uploaded to the map every Friday afternoon. You can find the map on the RSGB’s contest web page at rsgb.org/radiosport Since 2011, the Bath Based Distance Learning team has helped nearly one thousand students to obtain their Full licence. Student feedback is always very positive and the pass rate continues to be well over 80%, compared with a national average of around 66%. The BBDL team is now planning another Full-licence level course. The course will run from the end of August to December, with exams in January. Students receive weekly work packages via an online classroom and have access to weekly online tutorials. Each student is allocated to one of the remote tutors who provide feedback and additional guidance. There are weekly quizzes to check on progress and at the end of the course there are a number of mock exams. There is no charge for the training, but applicants must work through some pre-course material and complete a quiz to be eligible for a place. This focuses on the ‘new’ Intermediate topics that were introduced to the syllabus in 2019. The aims of the pre-course classroom are to make sure applicants can use the BBDL systems and to ensure that they are ready for the current Full training syllabus. Each student will need to provide their own RSGB Full licence textbook and arrange their own exam at the end of the course. Advice will be provided as part of the course. The deadline for course applications is Tuesday the 25th of July. To request full details and an application form, please email BBDL Team Leader, Steve, G0FUW, via [email protected] International Museums on the Air will take place on the weekends of the 17th and 18th, and the 24th and 25th of June.

Using phone on the 6m band, the exchange is signal report, serial number and Worked All Britain square.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 8th of June 2023 Solar activity has remained at low levels over the past few days with only minor C-class and one M-class flare detected. The majority of these small flares were produced by active region 3327 in the southeast quadrant. But a large number of sunspots means we are at a high risk of M-class or even higher flares over the next week. HF conditions for last weekend’s Field Day were good and most teams put in good scores. Sporadic-E wasn’t too evident on HF, but there was plenty of F-layer DX to be had and luckily an anticipated geomagnetic storm never materialised. The Kp index remained low for the whole weekend, apart from a brief excursion to Kp4 late on Sunday evening, which only lasted until the next three-hourly update. Next week the Space Weather Prediction Centre thinks the solar flux index will be in the range of 140 to 155, with 155 coming much later in the week. We may expect some geomagnetic disturbance over this weekend, with the Kp index perhaps reaching four on Sunday the 12th. Looking further ahead, the 18th to the 21st is predicted to be unsettled with a maximum Kp index of five. We really are into a period of summer HF propagation now, which is characterised by lower maximum useable frequencies during daylight hours, but higher MUFs during night-time. According to Propquest, night-time MUFs over a 3,000km path are staying well above 14MHz and even 18MHz all night. You may even find DX on 21MHz up until midnight. So don’t write off the HF bands after dark as you may get some surprises.     And now the VHF and up propagation news Sporadic-E produced some remarkable conditions early last week with 50MHz FT8 QSOs made with Australia during the day and afternoon and evening openings to the Caribbean, Central, North and South America on FT8 and CW. Caribbean signals were still being copied at 2200UTC on some days. The 5th produced QSOs for many on 70MHz including S01WS in Western Sahara. We are still in the peak Sporadic-E season, so it is well worth keeping a check on band activity via the various clusters or simply listening, particularly in the late afternoon. The current weather setup is quite typical for this time of year and can be remarkably persistent. Although there have been suggestions of unsettled thundery weather arriving, it may be a brief visit and rather limited in extent. Some eastern areas stay close to the high pressure which becomes more dominant again throughout next week. This means that Tropo will still be a component of the coming week’s propagation, especially along North Sea coasts, although this will tend to favour northern Britain as the week progresses. The thundery weather could introduce rain scatter, especially to southern and western areas, and these storms should be easy to track in view of the light upper winds. Recent solar conditions, as detailed in the previous section, continue to provide propagation variety with chances of aurora plus the usual mention of random meteor scatter. Moon declination is still negative until Monday, and, as we are past perigee, we will have lengthening Moon windows and rising path losses. 144MHz sky noise is low all week. And that’s all from the propagation team this week.

Although we started the week with the Solar Flux Index in the low 150s, it quickly picked up to reach 161 by Thursday. As a result, there was DX to be had, although most of the attention was on 6m where some outstanding multi-hop DX contacts were being made. But back on HF and people have been chasing T31TT on the Central Kiribati Islands. Some have made it, but it's a difficult path. Closer to home, Nobby Styles, G0VJG and Emil, DL8JJ have been active on Rockall, which is IOTA EU-189, using the callsign MM0UKI. Rockall is an uninhabitable granite islet situated in the North Atlantic. The nearest permanently inhabited place is North Uist, an island in the Outer Hebrides of Scotland, 200 nautical miles to the east. They have been worked from the UK mainland on 30m and 20m and heard in the east of England on 15m, possibly via Sporadic-E. They may have been a little too close to northern areas for 20m as you may have been inside their skip zone. One of their aims is to raise as much as possible for the Royal Navy and Royal Marines Charity and ABF, The Soldiers’ Charity, so please support them if you can. This weekend we may have unsettled geomagnetic conditions partly due to an Earth-facing coronal hole with the Kp index peaking at five. But after the weekend things may settle with a maximum Kp index of two. The solar flux index is predicted to be around 150, declining to 130 as the week goes on, so HF conditions may be down a little on last week.   And now the VHF and up propagation news The weather pattern seems stuck in its typical late spring/early summer state with cold north-easterly winds in eastern areas. There are good prospects for western Britain to shine but leaving eastern areas struggling. The root cause is a large area of high pressure that is over northern Britain, and currently trying to transfer to the east, which could improve things. Either way, it does mean that Tropo was doing a lot of the propagation work last week and will do so for much of next week too. As the high edges east, or splits into one to the west and one to the east of the UK, it could leave room for isolated thundery showers to encroach into southern and southwestern areas and give a chance of rain scatter on the GHz bands. The main mode of interest will probably be Sporadic-E and there have been a few examples in the last week, both single-hop within Europe and multi-hop paths to the States, the Far East and Australia. The first week of June is typically a prime period for Sporadic-E and although the jet stream position suggests mainly paths northeast to Scandinavia and Baltic regions will be best, other multi-hop options farther afield are worth exploring too. Monitor the clusters and band maps to see where the activity is happening. If you hear this in time, you might want to check out the 24-hour UK Six Metre Group Summer Sporadic-E contest which ends at 1300UTC today, the 4th. There should be plenty of activity. Other modes may also pop into view, such as aurora and meteor scatter, so we may be spoilt for choice. Moon declination is negative all week and still falling until Tuesday. We are past apogee so path losses will fall as the week goes on. So we will also have short Moon windows with falling path losses until perigee late Tuesday. 144MHz sky noise is high, reaching a peak of 2700K on Monday and only going below 300K by Friday. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for May 28th 2023

GB2RS News Sunday the 28th of May 2023 The news headlines: RSGB Tonight@8 webinar RSGB Beaconnect loop experiments RSGB School Zone web page   On Monday the 5th of June, the RSGB’s Tonight@8 live webinar will feature Mike Richards, G4WNC who will give a presentation on Node-RED for radio amateurs. Node-RED is a visual programming language that is very powerful but surprisingly easy to use. The language has matured over recent years and has the potential to be a valuable tool for radio amateurs. In this talk, Mike will provide an introduction to Node-RED programming techniques. He will conclude with a live demonstration to show just how easy it can be to add extra facilities to your rig. Watch and ask questions live on the RSGB YouTube channel or special BATC channel. For more information see the RSGB website at rsgb.org/webinars Three weekends have been identified for some RSGB Beaconnect loop experiments. On the 3rd and 4th of June, there will be some regional loops and nets. On the 10th and 11th of June, there will be an England-only loop and net based round the activators who have registered for Beaconnect callsigns so far, but the Society would welcome new activators in the West of England and East Anglia. Finally, on the 24th and 25th of June there will be an attempt at a multiple nations loop, although to do so the Society will need activators in Wales, Scotland and Northern Ireland. If you want to join in with these activities, register for a Beaconnect callsign via the RSGB website. Go to rsgb.org/coronation and choose the Beaconnect information page. The RSGB’s School Zone web page brings together radio amateurs in schools and colleges. The Society wants to help people to share their experience and expertise in establishing and running a radio club for young people. The RSGB has just launched a new page as part of this section called ‘School Zone stories’ where it is highlighting some of the great amateur radio activities that are happening in these, and other, schools. If you’re a school with an amateur radio club and want to be added to the list, or a radio amateur or club that is linking with local schools, the RSGB would love to add your information and stories to School Zone. Go to rsgb.org/school-zone to find out more, or send your stories and photos to [email protected] Have you seen the RSGB Live News web page? It brings together the Society’s social media feeds, latest YouTube videos and front-page news in one place. Launched a few years ago, people found it very useful, so the RSGB is highlighting it again now for those who have become radio amateurs or returned to amateur radio more recently. Take a look at rsgb.org/live for a taster and then go to the individual comms channels to find out more. The Worked All Britain group will be holding its AGM on Sunday the 11th of June at 12pm.

Using all modes on 1.3, 2.3 and 3.4GHz frequencies, the exchange is signal report, serial number and locator.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of May 2023 The Sun currently has an equal number of spots in both its Northern and Southern hemispheres. The Solar Flux Index was consistently in the 150 to 160s range last week, with a total of eight M-class flares. We had unsettled geomagnetic conditions on the 21st and 22nd when the Kp index hit six, but things then settled down again to a more manageable two to three. There are times when the F-layer critical frequency is lower than the E-layer critical frequency due to Sporadic-E. This means that HF signals can’t reach the F2-layer, basically blocking off DX, but leaving Sporadic-E short skip available. So, make the most of these short-skip contacts to the continent and multi-hop Sporadic-E skips to further afield. Conditions in the F2-layer will improve in the autumn, so don’t worry! There is still HF DX to be had, but you may have to hunt for it. Recently, Laurie, G3UML worked BD4VGZ in China on the 15m band using CW and Stuart, M1SMH worked YG2ALQ in Indonesia as well as A71UN in Qatar, on the 10m band using FT8. Meanwhile, Andy, M0NKR worked VK on the 15m band using SSB long path. Namibia, Malawi and Equatorial Guinea have all been workable from the UK using FT8 on the 10m band during late morning. Next week NOAA predicts that the Solar Flux Index will remain in the same range. That is, in the 150 to 160s. Unsettled geomagnetic conditions are forecast from the 2nd to the 4th of June when the Kp index might reach four. Otherwise, it suggests that conditions will be mainly settled with the Kp index around two to three. So, make the most of the elusive HF F2-layer openings and the various opportunities available during this peak time for Sporadic-E propagation. And now the VHF and up propagation news The broad scale pattern is still dominated by a large area of high pressure over the country with its centre mostly to the northwest of the British Isles. The whole period through to the end of the coming week should offer some good tropo prospects, so why not try using CW or SSB to add some extra squares to your log? Under lift conditions, even a halo antenna can be surprisingly effective. The weather variety will remain until the end of next week when low pressure over France tries to push some thundery showers northwards into southern Britain after midweek, and perhaps then northwards as far as western Scotland. This brings a chance of rain scatter on the GHz bands. There is, as usual, always a chance of aurora and meteor scatter to bring additional options, but the main mode of interest this week will be Sporadic-E as we head into the peak of the season. With tropo also in play, it’s worth a quick note for those not used to working Sporadic-E; Tropo tends to be long-lasting and usually better on the higher bands. That is to say, the 70cm band is often better than the 2m band whereas Sporadic-E is usually brief and better at lower frequency bands. So, the 10m band is better than the 6m band. This time of the year it can reach up to 2m on rare occasions. If you do nothing else, simply check the bands and clusters at the end of the afternoon to maximise your Sporadic-E chances. Moon declination is positive but falling this weekend, going negative on Tuesday. We are past apogee so path losses will fall as the week goes on. We’ll see shortening Moon windows with falling path losses. 144MHz sky noise is low all week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for May 21st 2023

GB2RS News Sunday the 21st of May 2023 The news headlines: Youngsters on the Air camp RSGB Board appointment RadCom Basics Editor   The RSGB has announced the team of young members who will be representing the Society and the UK at this summer’s Youngsters on the Air camp. The event, hosted by the Hungarian Radio Amateur Society MRASZ, will take place in Gyor, Hungary between the 5th  and the 12th of August. The team is made up of team leader Alexander, 2E0FMZ and members Henry-James, M7HJR; Hannah, M7YYQ and Jake, M7JNS. You can read more about the camp and the team on the RSGB website at rsgb.org/yota-hungary The RSGB Board has decided to co-opt Ian Shepherd, G4EVK as a Board Director until the 2024 AGM. Please see the Board’s explanation of this appointment on the Society’s website at thersgb.org/go/boardcoopt The RSGB is sad to report that RadCom Basics Editor Lee Aldridge, G4EJB wishes to retire later this year. The RSGB thanks Lee for all his hard work and effort in the making of RadCom Basics. If you are interested in taking on the role of RadCom Basics Editor, please email [email protected] Last year, the RSGB was approached by the BBC to find experts to contribute to its planned series ‘The Secret Genius of Modern Life’. For episode one, which takes a look at the bank card, Neil Smith, G4DBN re-created the Great Seal Bug – a wooden seal, gifted to the US embassy in Moscow in 1945, and which contained a covert listening device. The technology developed for the bug was an early example of RFID, which is what allows contactless card payments to work. Neil has now released a series of fascinating videos on his YouTube channel which explain the history of the Bug as well as the mechanical design and machining needed to re-create it. You can find the videos in Neil’s playlist on ‘Machining and Microwaves’ and you can watch the original BBC Two programme on BBC Sounds – this episode is available for a further seven months. The RSGB National Radio Centre welcomes thousands of people through its doors each month and needs to expand its team of volunteers. If you are interested in becoming an NRC volunteer, you should enjoy meeting people and be prepared to work a minimum of one – preferably two – days per month. The team is particularly interested in recruiting new volunteers who are able to work at the weekend. The National Radio Centre has a fabulous set-up and full training on using the GB3RS radio station will be given. You will be joining a friendly and dedicated team. NRC volunteers also enjoy numerous benefits associated with volunteering at Bletchley Park. For more information about volunteering, please email NRC Coordinator Martyn Baker, G0GMB via [email protected] Interest in QRP activity is as strong as ever in the worldwide amateur radio community.

On Sunday the 28th of May, the UK Microwave Group High Band Contest runs from 0600 to 1800UTC. Using all modes on the 5.7 and 10GHz bands, the exchange is signal report, serial number and locator.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 18th of May 2023 After last week’s NOAA prediction that we would have settled geomagnetic conditions all week, it seems they were right! The Kp index never got above three – a miracle given the recent disruption due to coronal mass ejections and coronal holes. The proton flux from the Sun has declined as well. However, an M9 solar flare on Tuesday from active region 3310, and numerous C-class flares, maybe a precursor to more flare activity next week. With a solar flux index in the 130s and 140s, HF conditions have been quite good. Daytime maximum usable frequencies over a 3,000km path have usually exceeded 21MHz, with 24MHz seeing occasional F2-layer openings, as well as sporadic E propagation. At the moment, the 10m band is mainly open to Sporadic-E propagation with more DX paths now locked out until the Autumn. This is in line with predictions, as the ionosphere changes in the Northern Hemisphere summer with a change to more diatomic elements, which are harder to ionise. So, will our luck hold out next week? The Space Weather Prediction Centre forecasts that the Solar Flux Index, or SFI, will decline slightly to the 120s and this weekend should be geomagnetically settled. However, it is predicting that the Kp index will rise again from the 23rd of May. It suggests that the Kp index may hit four or even five for a few days before becoming more settled again from the 30th. The US Air Force disagrees and thinks the SFI will be higher, perhaps hitting 145 and even 155 by the 28th. It agrees that we are in for more unsettled geomagnetic conditions from the 24th to the 28th, possibly due to a coronal hole rotating into an Earth-facing position. So, expect MUFs to decline if the Kp index goes up, with poor overall HF conditions. It is certainly looking like this weekend may see the best conditions for HF, so we suggest you get your DXing in right now, with 14 to 21MHz offering the best prospects.   And now the VHF and up propagation news The upcoming weather week will be predominantly high-pressure driven, with an elongated region of high pressure from the Azores to Scandinavia. However, there is still scope for a few blemishes and as we end the current week it comes as isolated showers, especially in the south and weakening fronts over north-western Britain. Early next week, a brief period with low pressure over the near continent will threaten some heavier rain for south-eastern areas. Concentrating on the high-pressure part of the story, this means Tropo is a strong player and will hopefully be in attendance for the 144MHz May Contest and 144MHz Backpackers Contest this weekend.  Remember that, in the summer months, Tropo becomes much weaker over the land during the stronger heating of the daytime sunshine but can become quite widespread overnight and around coasts. The rainfall component can lead to good rain scatter options, especially as the summer usually produces more intense rainfall, so performs better as a scatterer on the GHz bands. The other primary propagation mode is going to be Sporadic-E as we move into the peak summer months. Follow the position of jet streams on the upper air charts, shown on propquest.co.uk and described in a daily blog. Don’t forget there are always modes like aurora and meteor scatter, which can add to the excitement, but will need to be checked each day. Moon declination is at its highest this weekend for the Dubus EME 10GHz and up SSB/CW contest, peaking on Monday. With apogee next Friday, path losses will continue to increase. 144MHz sky noise is moderate early next week becoming low by Thursday. And that’s all from the propagation team this week.

UK and Crown Dependency stations also send the first two letters of their postcode.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 11th of May 2023 Our topsy-turvy world of HF propagation continued last week with geomagnetic storms, solar flares, coronal mass ejections, proton events and more. The good news is that the solar flux index was at 170 by Thursday, but the bad news was that we had two episodes where the Kp index hit five and there were at least five M-class flares.  At least one of these flares was responsible for a coronal mass ejection, or CME, which swept past the Earth on the 10th of May with a solar wind speed close to 700km/s. Although it was fierce, it was relatively short-lived and the Kp index was back to three on Thursday the 11th. The CME caused the maximum usable frequency over 3,000km to decline to around 21MHz at times on Wednesday, but by Thursday morning it was back up to nearly 28MHz. The high proton flux also caused problems on the 10th of May. The protons, mainly from CMEs, move down the Earth’s magnetic field lines into the polar regions and cause massive ionisation of the polar D region leading to increased, or total, absorption of HF waves. This effect may last for as long as ten days and is called a Polar Cap Absorption event, or PCA. This affects signals going over the poles, such as the UK to the west coast of Canada and the USA, or to Japan and the far east. Meanwhile, we are now underway with the Sporadic-E season, so make the most of the short skip and potential multi-hop Sporadic-E DX on 14 to 28MHz. Next week, the Space Weather Prediction Centre has the Solar Flux Index declining slightly into the 150s. This is still more than enough to maintain DX on 21MHz and higher at times. It also predicts that the Kp index will be no higher than a stable 2 all week. However, that is hard to believe, with the level of solar activity at the moment, and we could reasonably expect the Earth to be hit with a CME or two at some stage. This could see the Kp index rising with the potential of reduced MUFs at times.   And now the VHF and up propagation news After a very unsettled end to the week, with lots of rain scatter reported, it will soon quieten down as a ridge of high pressure builds across the country to give some limited Tropo opportunities for the start of the weekend. This will not last long and by this evening, it will be heading back to unsettled with low pressure, heavy rain and rain scatter. This unsettled theme will last through the first half of the new week together with strong north-easterly winds. Thereafter, high pressure will build again for the second half of the week, providing further Tropo options. Keep a watch for Aurora, especially in view of the current unsettled solar state. CMEs will mean a very unsteady Kp index and anything higher than five should get your attention for auroral propagation. No significant meteor showers are expected this week, but QSOs using random meteors are always a possibility in the dawn hours. Likely to be of interest in the summer months ahead, there have already been Sporadic-E openings on 6m CW and FT8 into Europe. Early evening trans-equatorial 6m FT8 QSOs to South America, the Indian Ocean and the South Atlantic were reported from the UK last week. Check Propquest.co.uk for daily blogs and make use of the DX cluster and map plots to see where the actual centres of activity are located. Timings can be a bit random early in the season, but there tend to be two ‘openings’ per day – one in the morning and a second during the late afternoon or early evening. Moon declination is rising, going positive again next Tuesday. But last Thursday’s perigee means path losses are on the increase. 144MHz sky noise is low until Friday when the Sun and Moon are close in the sky for the whole Moon window. Things return to normal early on Saturday and sky noise is moderate. And that’s all from the propagation team this week.

Put the date in your diary for an interesting presentation by Jack Purdum, W8TEE and Al Peter, AC8GY on the T41-EP ALPS: A High Performance CW Decoder. Matthew, M0MZB from Calder Bridge in Cumbria, has become a SOTA Mountain Goat in impressive style. He reached the 1,000 activation point threshold with an overnight activation of High Stile G/LD-012 in the English Lake District. Matthew set up overnight camp on the summit of the long ridge above the western shore of Lake Buttermere. He operated both on VHF and HF and made a summit-to-summit contact with Alex Hill, G7KSE who was on the Dent summit, G/LD-045. Since getting involved in Summits on the Air, Matthew's expeditions have left many radio amateurs in awe. He has conducted many multi-summit expeditions without motorised transport, traversing between summits entirely on foot or by bicycle. Upon reaching the coveted Mountain Goat status, Matthew commented: "SOTA has given me new ideas for my little expeditions and has put me in touch with lots of new friends. The challenge of Mountain Goat has included many facets, from learning CW to antenna building, from battery technology to fishing poles."

Using all modes on the 24, 47 and 76GHz bands, the exchange is signal report, serial number and locator.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 4th of May 2023 Next week will see the Sun presenting with four large sunspots groups that are rotating to be Earth-facing, so look out for trouble. Just as the UK weather takes a turn for the worse, we expect the space weather to be unpredictable too! Active regions 3293, 3294, 3296 and 3297 look dark and are looming large on the Sun’s face. Region 3293 emitted an M7.2 class solar flare on the 3rd of May, which the Space Weather Prediction Centre reported was likely due to an intensification of the magnetic field within the spot group. The flare caused some degradation of the ionosphere, but nothing too serious. However, the Space Weather Prediction Centre now predicts that further flares could follow, perhaps even a strong X-class flare, which could have more serious effects. If an X-class flare occurs in daylight over the UK, we can expect the HF bands to be affected in what is known as a sudden ionospheric disturbance or Dellinger fadeout. This could see the lower HF bands shut down due to extreme ionisation in the D-layer, only for the band to return to normal over a period of minutes to an hour. More worrying is the fact that the flare could spark a coronal mass ejection, or CME, which, if Earth-directed, could cause the Kp index to rise, MUFs to drop and bring auroral activity a few days after the CME. So, keep an eye on solarham.net for updates. Meanwhile, the solar flux index, or SFI, remains in the 150s and this looks set to continue. The US Air Force predicts the SFI will start the week at 152, then dip slightly, before reaching 170 by the 12th of May. It also predicts that geomagnetic conditions will be settled once we get past this weekend, which could see the Kp index rise to four. These unsettled conditions may be due to a coronal hole, which became Earth-facing on Thursday. Propagation-wise, F2-layer maximum usable frequencies over a 3,000km path has struggled to exceed 21 to 24MHz during daylight hours as we head towards summer. The season is characterised as having lower MUFs during the day, but these tend to be maintained into the hours of darkness. Meanwhile, Sporadic-E might spring some surprises for paths over 800 to 2,200km on 14 to 28MHz, with very strong signals and rapid fading.   And now the VHF and up propagation news The weather pattern is taking a change to unsettled as we move through this first May weekend, with low pressure dominating the charts and throwing active weather fronts across the country. This will produce some quite heavy rain at times and perhaps even some thundery activity. This bodes well for rain scatter on the GHz bands. This pattern extends well into next week, eventually changing from a south-westerly to a north-westerly followed by a building ridge of high pressure to bring a temporary hint of Tropo to end the week. This opens the more exotic modes to consider, such as meteor scatter and possible aurora, but these are very much outliers to the main interest at this time of year, which is Sporadic-E. The season has nominally started, and daily blogs are being added to the website Propquest.co.uk, which describe the more likely regions to find Sporadic-E opportunities. This unsettled weather pattern brings a useful bonus in that it is often associated with jet stream activity. The whole period offers several jet streams across Europe, a positive for the start of the new Sporadic-E season since jet streams are often associated with the location of Sporadic-E activity. Moon declination is low and falling, reaching minimum next Tuesday. EME Moon windows will be short. Perigee is Thursday, so when you do have a view of the Moon, path losses will be low. 144MHz sky noise is high, reaching over 3200K late on Monday. And that’s all from the propagation team this week.

It started with a massive G4 geomagnetic storm that saw the Kp index rise to eight with aurora visible as far south as Cornwall and the Channel Islands. This was due to a coronal mass ejection from a filament eruption on the 21st of April. The 6m band came to life during the early stage of the storm with distorted aurora signals throughout the SSB and CW sections. However, the HF bands suffered, with MUFs down on the morning of the 24th. The 25th wasn’t much better with MUFs over a 3,000km path barely reaching 18MHz all day. By Thursday the 27th the Kp index was still at four. However, there were surprises to be had. Phil, GU0SUP reported that at 1300UTC on Monday the 24th, he was amazed to work Yuris, VU7W on the Lakshadweep Islands on 10m FT8, with good signals both ways. He says the Kp index was at six and the regular FT8 frequencies on both the 10m and 12m bands were pretty much dead. On Wednesday the 26th, Peter, G8BCG reported, on the CDXC reflector, that 15m FT8 was open all night via the long path to Australia, New Zealand and the Pacific. It is always worth checking the HF bands during a major geomagnetic storm as there may be surprises to be had. Next week the Space Weather Prediction Centre thinks that the Solar Flux Index will remain in the range of 135 to 140. The Kp index may remain around two to three. However, as last week showed, we are now really into uncharted territory, in terms of solar activity, with daily multiple solar flares and associated coronal mass ejections. So, don’t be surprised if we have another major geomagnetic disturbance with an elevated Kp index.   And now the VHF and up propagation news The weather pattern in late spring often settles into a period of south-easterly winds from a rapidly-warming Europe and the signs are there for just such a flow during the coming week. The sequence starts with unsettled weather and possible rain scatter from heavy April showers into the first weekend but, thereafter, a weak ridge of high pressure will move in to bring a chance of Tropo for next week. Paths along the east coast should do well, especially if there are large areas of sea fog and misty low clouds over the North Sea. At longer timescales, the period towards the following weekend will see eyes looking towards a low to the southwest of the British Isles that could push some thundery rain into southern areas by the end of the week and again bring a chance of rain scatter on the GHz bands. The jet stream pattern remains complex with several potentially useful flows that might be instrumental in prompting some early-season Sporadic-E propagation. Last week, the Portuguese CS5BALG beacon on 50.036MHz in IM67, and CS5BLA on 50.0760MHz, made a welcome return. Sporadic-E can be very fleeting early in the season, but keeping a regular check on the usual beacons should give you a chance of being there at the right time. The daily Sporadic-E blogs start on the 1st of May on www.propquest.co.uk and should give some clues as to any early-season options. Lastly, the Sun has kept everyone busy recently with visible and radio auroras, so check the Kp index for aurora potential. And we are in a period when increasing meteor input is starting to help provide better meteor scatter prospects, as well as fuel for Sporadic-E. The Eta Aquariids has a broad peak zenithal hourly rate of around 50 next weekend on the 6th of May. Moon declination is high and falling, meaning shortening EME Moon windows and peak elevations. We passed apogee on Friday so path losses will fall throughout the week. 144MHz sky noise is low to moderate. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for April 24th 2023

  GB2RS News Sunday the 23rd of April 2023 The news headlines: RSGB Coronation activities RSGB AGM announcements and videos RSGB Board Chair   The RSGB is delighted that Ofcom has confirmed that the callsign GB23C can be used for the RSGB’s Coronation Special Special Event Station. Cray Valley Radio Society members led by Bob, M0MCV and Dave, G4BUO are organising the flagship amateur radio station that will use this callsign from the 3rd to the 8th of May. The Special Special Event Station will be on the grounds of the Old Royal Naval College, along the riverside in Greenwich. From the 10th of May onwards, the callsign will be available for individuals and clubs to use until the end of June 2023, and further details about this will be announced shortly. Ofcom has also kindly agreed to a block of 676 Special Special Event Station callsigns for the RSGB’s Be a Connect activity for the Coronation. These are GB23BAA to BZZ, which will be available throughout May and June. More details on how to obtain one of these will be given next week, but meanwhile, you may wish to find a beacon site you could activate one or more times for this event. Finally, if you are planning outreach activities with local clubs and groups, take a look at the paper circuit template the RSGB has just shared on its website – go to rsgb.org/coronation and choose the coronation activity ideas tab in the right-hand menu. The RSGB’s AGM was held online last Saturday, the 15th of April. If you missed the live event, you can see the results of the elections and follow links to the trophy awards and the construction competition winners on the RSGB website via rsgb.org/agm. You can also catch up on the full live stream or watch individual sections on the Society’s YouTube channel. The RSGB has released separate videos of the outgoing President’s review of 2022, its new short Convention promo, and the interesting presentation about preparing the GB2RS propagation reports by the RSGB Propagation Studies Committee Chair, Steve Nichols, G0KYA. You can see them all in the RSGB 2023 AGM playlist on YouTube via youtube.com/theRSGB   Following the RSGB AGM on Saturday the 15th of April, a brief Board meeting was held to consider necessary appointments. The Board was aware that Stewart Bryant, G3YSX, who had been in a dual role since the recent resignation of Richard Horton, G4AOJ, had expressed a willingness to continue as Chair if required. It was agreed that Stewart should be co-opted to the Board under the terms of Article 37 and was asked to join the meeting. Stewart was then elected unanimously to serve as RSGB Board Chair until the 2024 AGM. This a reminder now that SOS Radio Week 2023 starts at midnight on the 1st of May and concludes at midnight on the 31st of May. It is an opportunity to support the many voluntary organisations in the British Isles whose members volunteer to save the lives of others at risk around the many miles of its coastline, and out at sea. These organisations include the Royal National Lifeboat Institution, the National Coastwatch Association and numerous independent lifeboat and coastal rescue groups.

UK and Ireland stations also send their District Code.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 20th of April 2023 We had a surge in sunspot activity over the last week, pushing the solar flux index up to a maximum of 178, although it subsequently declined to 147. Solar flare activity was quite subdued after a frantic period from the 13th to the 15th that saw 40 C-class flares and two M-class flares erupt. This activity was mostly centred around active region 3282 in the northwest quadrant. Geomagnetic conditions were unsettled for a time around the 18th and 19th with the Kp index hitting a maximum of 4.3. This appears to have been due to enhanced activity from a coronal mass ejection and continuing coronal hole activity that saw the solar wind speed hit more than 600km/s and the Bz swing south. The critical frequency was down below 7MHz on the morning of Wednesday the 19th, which impacted near-vertical incidence skywave signals around the UK. This impacted maximum useable frequencies, which struggled to exceed 21MHz over a 3,000km path on Wednesday, although by Thursday they were back over 28MHz again. A critical frequency of more than 10MHz meant the 40m band was once again suitable for close-in contacts around the UK. There were many reports of DX being worked later on during the week, with Australia and New Zealand topping the bill on 18MHz and 28MHz. Next week NOAA has put a more positive spin on sunspot activity. The Solar Flux Index is predicted to be in the range of 168 to 172 for the first half of the week, falling to around 160 in the second half. But we could be in for a bumpy ride geomagnetically, with the Kp index predicted to hit five on Wednesday the 26th of April through to Monday the 1st of May. This may be due to the return of solar phenomena that occurred 27 days ago and saw the Kp index get up to 4.67. Meanwhile, a very large solar coronal hole, albeit positioned very south on the Sun’s surface, and a much smaller one on its equator, threaten HF conditions this weekend. Keep an eye on the real-time solar wind from the ACE spacecraft for signs of a rise in speed and a southward-pointing Bz interplanetary magnetic field on solarham.net.  This could push to Kp index higher, perhaps to four.   And now the VHF and up propagation news The Sporadic-E season is nearly upon us. Remember it will usually activate on 28MHz and then higher bands will follow if the event intensifies. There have been some 50MHz FT8 paths flagged up on DXmaps.com, although some may have been tropo. The recent large high pressure centred over Scandinavia has been a bit subdued as regards Tropo. Much of the time, the air nearer the surface has been fairly dry with little sign of banks of sea fog over the North Sea, which would suggest better ducting potential.   We are now entering a phase with low pressure on the charts, initially over the south of Britain, but edging north for a time before drifting out across the North Sea.  This could produce some rain scatter on the GHz bands, especially should any heavy April showers develop. Early next week a ridge will edge south across the UK in a colder northerly weather pattern, so although high-pressure returns, it may not be especially good for tropo. The third changeover comes after midweek when a milder south-westerly returns with active fronts bringing rain and unsettled weather, especially to the north and west. This could mean further opportunities for rain scatter on the GHz bands and perhaps a hint of tropo in the Southeast towards the continent. Aurora and meteor scatter are well worth considering, and the Lyrids shower peaks on Sunday the 23rd. The message is to monitor meteor scatter frequencies and the clusters for signs of activity and, of course, try putting out a CQ call! Moon declination is positive and rising, meaning increasing Moon time and increasing peak elevation until peak declination on Tuesday. Moon apogee is next Friday so path losses increase all week. 144MHz sky noise is moderate to low. And that’s all from the propagation team this week.

Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number. Polish stations send their province code. The British Amateur Radio Teledata Group Sprint 75 Contest runs from 1700 to 2100UTC on Sunday the 23rd of April. Using 75 Baud RTTY on the 80 to 10m bands, where contests are permitted, the exchange is a serial number.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 13th of April 2023 A news item this week suggested that the peak of solar cycle 25 could be coming earlier than expected. According to a paper in Frontiers in Astronomy and Space Sciences, by solar scientist Dr Scott Macintosh, the solar maximum may now be coming between late 2023 and mid-2024. So, make the most of the higher Solar Flux Index now! Solar activity picked up nicely over the past week. The solar flux index rose to 154 and there were eight active regions on the Sun’s visible face by Thursday the 13th. Nevertheless, daytime maximum usable frequencies, or MUFs, remain down a little, which has probably more to do with seasonal ionospheric changes than reduced sunspot activity. As we head towards Summer we will see the daytime F2-layer MUF decline further before it picks up again in the Autumn. We also saw some M- and C-class solar flare action this week, but this was not really enough to cause serious problems to the ionosphere. Next week NOAA predicts the Solar Flux Index will continue to increase, perhaps peaking at 160 around the 16th to 18th of April. Unsettled geomagnetic conditions are forecast for the 18th, perhaps with the Kp index rising to four. The forecast for International Marconi Day on the 22nd of April is for a Solar Flux Index of 155 and a declining Kp index of three, which bodes quite well for the event. In all, the Solar Flux Index is expected to be in the range of 140 to 160 for the rest of the month.   And now the VHF and up propagation news A big contrast is coming next week, so it’s time to dust off the VHF gear again! The unsettled weather of this last week will make a complete swap over to more settled high-pressure systems next week.  Initially, on Sunday this will appear as a ridge over the North Sea from a large high over Scandinavia. This will then gradually extend across the country and will eventually be joined by a second high west of Britain.  The end result will be enhanced Tropo prospects in the coming week and potentially good conditions for the 23cm UK Activity Contest on Tuesday the 18th and the 4m UK Activity on Thursday the 20th. Those who enjoy rain scatter propagation in this current showery weather will have to look for other modes by Sunday, once the high pressure builds. As we are coming out of the Winter lull in meteor shower activity, with the medium-rate Lyrids peaking on the 23rd of April at 0100UTC with a Zenithal Hourly Rate, or ZHR, in the 20s, it's well worth a look for meteor scatter contacts. The end of April normally prompts a return of isolated Sporadic-E reports on the 10m band and perhaps even with data modes on 6m. The upper troposphere jet stream charts suggest it’s got some potential, especially between Mediterranean countries although not quite so positive for paths nearer to home. The solar conditions may continue to offer a random chance of some aurora, so remember to keep an eye on the Kp index if it goes above five.   For EME operators, the Moon perigee is on Sunday so path losses are at their lowest. Moon declination is rising, going positive on Tuesday meaning increasing Moon time and increasing peak elevation passes. 144MHz sky noise is low, but the Moon is close to the Sun on Wednesday and Thursday meaning high Sun noise for those days. And that’s all from the propagation team this week.

Using all modes on the 6m band, the exchange is signal report, serial number and locator.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 6th of April 2023 Solar activity declined this past week with the Sun looking distinctly spotless, other than active region 3270. In fact, this has even prompted some amateurs to question whether we are now past solar maximum for this cycle. Rest assured, we shouldn’t be, as it is pretty common for cycles to ebb and flow as they develop. Having said that, half of the Sun’s face is currently spotless, and NOAA predicts that the solar flux index will be in the range of 110 to 130 next week. Geomagnetically, things have been reasonably settled with the Kp index reaching a maximum of 4.67 over the past seven days. NOAA predicts that it could rise to four on the 10th and 11th of April but will otherwise stay pretty much as it is in the range of two to three. This may be due to a coronal hole that is currently making its way across the Sun’s face in a near-equatorial position. However, we may not have seen the last of the activity from active region 3270, which has increased in both size and magnetic complexity during the past 48 hours and could soon produce a moderate M-Flare. But, if you are reading or hearing this on Sunday, the region will be moving out of sight and is therefore no longer a threat. Daytime F2 critical frequencies at midday remain around 9 to 10MHz giving a maximum useable frequency, over a 3,000km path, of just over 28MHz. If 10m isn’t doing it for you we suggest moving down to 12 or 15m. Night-time F-layer critical frequencies are around 3 to 5MHz meaning MUFs over 3,000km are below 14MHz, leaving 3.5, 7 and 10MHz as the best bets for nocturnal DX. And now the VHF and up propagation news The current spell of high-pressure weather with enhanced Tropo, which turned up in time for the 2m UK Activity Contest on the 4th of April, is looking a bit vulnerable as active weather fronts come in from the Atlantic.  We are likely to have a brief change to unsettled conditions weather-wise before the start of the Easter weekend and again see some rain scatter opportunities on the GHz bands. Scandinavian highs are often long-lasting at this time of the year and this high will regain control by Good Friday and should dominate over the UK during the Easter weekend to give some useful tropo possibilities again. However, quite early next week a new powerful Atlantic jet stream pushes into northern France and will bring a return of unsettled weather and perhaps more rain scatter. The Sporadic-E season is approaching and the higher HF bands like 10m can show good examples of Es, even during the second half of April, so a good chance to get into the habit of checking your ‘go to’ list of 10m beacons as recently updated by Steve, G0KYA, on the propagation section of the RSGB website. The other defaults of auroral propagation have had a good run recently and random meteor scatter could also prove fruitful as we are soon ending the early year ‘drought’ of meteor showers with the arrival of the Lyrids later this month. For EME operators, Moon declination is negative and falling, reaching its minimum next Wednesday. Moon time will be limited to low-elevation passes, but with low path losses as we approach perigee on the 16th. 144MHz sky noise is increasing to a high of more than 2,000 Kelvin next Wednesday before falling back to the mid-200s the following Sunday. And that’s all from the propagation team this week.

This was probably the most significant geomagnetic event we have had so far in this solar cycle. Last week saw another X1.2 solar flare erupt on the Sun. This one erupted from active region 3256 on the 29th of March at 0233UTC. It didn’t impact the ionosphere over the UK, but a fadeout was observed over the Pacific region. This was the seventh major solar flare since 2023 began. The Sun has now matched 2022’s total –and it's only March! The associated CME off the southwestern limb of the Sun was modelled and determined to be well ahead of the Earth’s orbit. This means that we are unlikely to see the Kp index rise as a result of this event. This region also produced an M1.2 flare that peaked around 1407UTC and an M1.1 flare at 2347UTC. The earlier flare didn’t seem to affect the ionosphere too much according to the ionosonde data. A minor solar wind stream is heading for Earth and is due on Saturday the 1st of April. The material is flowing from a relatively small coronal hole in the Sun's atmosphere, but it is on the equator and very Earth-centric. Expect Arctic auroras and an elevated Kp index when the solar wind arrives this weekend. The SFI remained fairly static, around 160, earlier in the week but then declined to 148 on Thursday the 30th. NOAA predicts that this decline will continue next week, perhaps down to the low 130s. Once the weekend’s geomagnetic conditions recover, NOAA predicts that the rest of the week should be quite settled. This is good news for HF propagation, although do continue to watch out for solar flares and CME activity which could affect conditions and MUFs. And now the VHF and up propagation news We have three phases of weather to consider over the next week. Forecasts predicted an unsettled weekend with rain and strong winds, so should have provided a focus for rain scatter on the GHz bands. The weekend ends with developing high pressure which lasts into early next week. There is good potential for some tropo from Sunday afternoon until about Tuesday lunchtime. At the time of writing, the best paths are likely to be from southern England into the near continent, also via Biscay to northern Spain and across the southern North Sea to Denmark. The third phase occurs when the high moves to the south to allow fronts to move in from the Atlantic across northern Britain, but possibly still leaving tropo into France and across Biscay. Later in the week, the high pressure may head back north again to reintroduce tropo to northern areas. The Sporadic-E season is fast approaching, typically from mid-April on 10m. If anything does happen before then, check the propquest.co.uk website for the Es blog tab, which shows the current day’s jet streams and will maybe provide a clue for which direction to beam. Remember to look for aurora if the Kp index reaches five or more and, of course, meteor scatter around dawn for those random meteor QSOs.  For EME operators, Moon declination is positive until Wednesday, so still plenty of Moon time to get some QSOs in. Perigee was last Thursday, so path losses are now falling. 144MHz sky noise is low, rising slowly throughout the week. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for March 26th 2023

GB2RS News Sunday the 26th of March 2023 The news headlines: RSGB Elections RSGB Membership and communications Coronation regional secondary locator   If you are an RSGB Member, don’t forget to vote for the two candidates that you would like to see as Board Directors for the next two years. You can find out more about each of them on the RSGB website at rsgb.org/candidates and then there is a link at the top and the bottom of the page to cast your vote. Read their personal statements, watch the videos and see if their background, skills and aspirations match your view of what the Society needs. The decision about who to vote for is entirely yours, but please do vote – it only takes a few minutes and will help to ensure that the RSGB Board reflects your views.  As the RSGB continues to expand the use of its new Membership and management systems, it will make greater use of electronic communications to advise Members of important changes to their fees, benefits and offers as well as to send notifications for important publications and events. If you are an RSGB Member, please remember to keep your preferences and personal information up to date, including your callsign and email address, by logging into the Society’s Membership portal via rsgb.org/members or by contacting [email protected] As part of our Coronation celebration activities, Ofcom has approved “R” as the optional Coronation regional secondary locator prefix for all UK radio amateurs to use during May and June 2023. You will need to apply for a Notice of Variation – or NoV – and the form is now available on the RSGB website at rsgb.org/nov A group of radio amateurs in Jersey will be using a special event callsign GB3KCJ as part of the Coronation celebrations. An opportunity exists for groups in each of the UK Nations who have a regional secondary locator, and the Crown Dependencies, to apply for similar special event callsigns. Applications for special event callsigns can be made through the Ofcom web portal, as usual. Using the same format as the Jersey special event station callsign, applicants might consider the following if they are available: Scotland: GB3KCM; Wales: GB3KCW; Northern Ireland: GB3KCI; Guernsey: GB3KCU; and the Isle of Man: GB3KCD. The RSGB’s Tonight@8 summer programme begins on Monday the 15th of May when Jack Purdum, W8TEE and Al Peter, AC8GY will talk about “The T41-EP ALPS: A High-Performance CW Decoder”.

We were free of major solar flares with only one M-class flare occurring on the 20th. Geomagnetic conditions were mainly settled as well, but that could change this weekend thanks to a large coronal hole. The massive coronal hole on the Sun became Earth-facing on Thursday. A coronal hole is an area on the Sun’s surface with open magnetic field lines, which allows plasma to flow out. They appear dark when photographed in extreme UV light. Although the bulk of the hole is south of the Sun’s equator, a long finger reaches out to the equator, which makes it a potential threat to Earth. All eyes will be on the Kp index over the weekend as we expect it to increase, possibly dramatically as the solar wind impacts us. Solar wind speeds are likely to be in excess of 600km/s and continue into the weekend, resulting in isolated G1 storm levels. Keep an eye on solarham.net for updates. We are now at the spring equinox, so it is prime time for auroral activity. The spring equinox traditionally brings greater solar activity which results in an increased frequency of auroral displays. It is also a prime time for north-south HF paths, such as the UK to South Africa, and the UK to South America. Next week, the US Air Force predicts that the solar flux index will decline slightly to bring it into the range of 130 to 140. Once the weekend’s solar storm declines, we may expect a few days of relatively calm geomagnetic conditions before another period of unsettled space weather is predicted for Thursday the 30th and Friday the 31st. This could see the Kp index rise to five once again.   And now the VHF and up propagation news The overall unsettled nature of the current weather pattern is likely to continue for much of the period through to the end of next week, except for a brief ridge of high pressure crossing the country after the weekend. This might offer the only tropo potential for VHF operators. The rest of the time will probably be beset by bands of rain, showers and, at times, strong winds and introduce the prospect of some rain scatter on the GHz bands. It’s a week to focus on fleeting tropo, rain scatter and aurora as modes of choice. As we said earlier, the aurora is worth looking out for since the solar conditions are still very disturbed. As usual, good indicators are the Kp index values, which ideally should be five or greater to get our attention. The meteor shower calendar is still in its quiet period, and with no major showers to look for, it would be best to try your luck with random meteors, which tend to peak just before dawn. The Sporadic-E season has not started yet but is getting closer, say from mid-April on 10m, perhaps. For EME operators, Moon declination reaches maximum next Tuesday meaning long Moon availability windows. Path losses increase throughout the week and 144MHz sky noise starts out moderate, falling to low next weekend. And that’s all from the propagation team this week.

Using SSB on the 160 to 10m bands, where contests are permitted, the exchange is signal report and serial number. Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday 16th of March 2023 Last week was split in two, in terms of HF propagation. The first half of the week was characterised by excellent high-band conditions, with many people commenting on how good things were. The Kp index was low, there was a lack of solar flares and the solar flux index was high – perfect for HF. There were reports of openings to Hawaii and Alaska on 10m and Bob, MD0CCE said 10m had been open to the Pacific every night for the last five or six days. But it didn’t last and by Wednesday it all went pear-shaped. The Earth was hit by a fast-solar wind with a southward-pointing Bz on Wednesday the 15th, which increased the Kp index to 5.67. Its impact on the ionosphere was quick and very damaging, to such an extent that the two ‘local’ Digisondes at Fairford and Chilton couldn’t detect the F2 layer, leaving their traces blank. It happened again on Wednesday evening, with the Kp index hitting 5.67 once again. Luckily, it didn’t last long and the Kp index was back down to less than two by the morning and the MUF over 3,000km was back over 28MHz by mid-morning on Thursday. Next week, NOAA predicts that the solar flux index will remain in the range of 135 to 145. Unsettled geomagnetic conditions are forecast for the 20th but, as we know, anything can happen at this point in the solar cycle. Look for a low Kp index but, above all, get on the bands and see what you can work! And now the VHF and up propagation news The unsettled weather pattern seems likely to continue through the coming week driven by an undulating jet stream over the British Isles. This will mean, for yet another week, there is unlikely to be much good Tropo. It’s not all bad news though, since the unsettled part of the weather story may introduce some rain scatter on the GHz bands. The mention of jet streams should, in a month or so, raise the promise of some Sporadic-E activity, which is often geographically related to the position of jet streams. It’s probably a bit early for that, although it could be worth considering a look at 10 and 6m as we move towards the end of the month. 10m, and 6m if you're in the far South West, can also give some good Trans Equatorial propagation, this time of year. This is typical of the changeover period from the southern hemisphere to northern hemisphere Sporadic-E activity. As usual, the chance of aurora is still around, so keep a watch out on the clusters or spaceweather.com for all the latest news. Early-morning random meteors should stay on the checklist too. For EME operators, moon declination is low but rising, going positive again on Wednesday meaning Moon availability windows will lengthen. The Moon is at perigee today, so path losses are at a minimum. 144MHz sky noise is low this week, apart from the whole of Tuesday when the Sun and Moon are close to an eclipse. It is perhaps worth reminding new licensees that preparing a good list of HF and VHF beacons to monitor can be worthwhile, especially in quieter times before the summer Sporadic-E season gets underway. And that’s all from the propagation team this week.

Using RTTY on the 80 to 10m bands, where contests are permitted, the exchange is signal report, serial number and time.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday 9th of March 2023 It was business as usual last week with the solar flux index in the 180s, numerous C-class flares and, at the time of writing, 13 M-class flares over the past seven days. The Kp index has been mostly settled for this part of the cycle, averaging two to three all week. But this doesn’t mean there has been little activity on the Sun, just that any eruptions have been directed away from Earth. For example, a large prominence eruption off the Sun on the 7th of March resulted in a coronal mass ejection that stretched hundreds of thousands of kilometres into space. It is this type of activity that makes space weather predictions difficult. If it had been Earth-facing, we could have ended up with a highly-raised Kp index and extensive aurora. As it was, the event had little or no effect on Earth. Maximum usable frequencies continue to be high, but we are starting to see the effects of the Summer ionospheric changes that will see daytime MUFs decline. The MUF over a 3,000km path often doesn’t exceed 28MHz now until later in the morning. This is due to a seasonal change in the ionospheric chemistry and a shift from monatomic species to diatomic ones, which are harder to ionise. So, make the most of 10m as by mid-summer we may lose long-range propagation on 28MHz, other than through Sporadic-E events. We mentioned last week that this is a good time for North-South paths as we head towards the Spring equinox. That is, good paths to South Africa and South America are more likely now than they were a few months back. There have been a lot of stations on 10m in the late afternoon from South America so make the most of the propagation. Next week, NOAA predicts similar solar flux index figures, with the SFI being in the range of 170 to 185. The Kp index is predicted to be at two or three, with perhaps more unsettled geomagnetic conditions on Wednesday the 15th. As always, see solarham.net for more up-to-date information.   And now the VHF and up propagation news The unsettled winter weather has yet to give way to spring, so it's primarily low-pressure systems and periods of rain or snow that we will be dealing with in the next week or so. Whether it’s rain or snow, this unsettled pattern limits any Tropo options and leaves only GHz band rain-scatter as a propagation mode to explore. Generally speaking, the rain, or perhaps the point where the snow is melting as it falls, should provide better reflections, whereas, in very cold areas, where it is all snow, reflections may be weaker. This probably means that it will be southern areas that perform better with rain scatter. For the next few weeks, there are no significant meteor showers and therefore the pre-dawn random meteors will be the best options. Aurora, on the other hand, tends to favour the spring and autumn months, so in view of the current state of solar activity, as mentioned in the previous section, you should continue to monitor the Kp index for signs of activity and check the bands if it gets to the point that Kp equals five. For EME operators, after minimum declination this Thursday, Moon availability windows will start to lengthen. Path losses will continue to fall but we are still a week from the Moon’s perigee – its closest point to Earth. 144MHz sky noise is high, reaching over 2,800 Kelvin on Thursday. And that’s all from the propagation team this week.

HQ stations also send ‘HQ’.   Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 2nd of March 2023. The auroral event last week was probably the strongest we've had in this solar cycle. There were widespread visible aurora reports from the UK on Sunday the 26th of February. The Kp index eventually hit seven at 0900 UTC on February 27th, sparking widespread visible aurora alerts all over the UK for Tuesday evening as well. The solar wind speed gradually decreased to below 650km/s and the Bz component of the interplanetary magnetic field shifted to the north, bringing the Kp index down. March is always a good, or bad, month for aurora, depending on your perspective. The aurora is at its most active around the equinoxes in March and September. Active region 3234 also produced an M8.6 flare on the 28th, but as this was at 1750UTC, the radio blackout was restricted to the Americas. Any CME material was directed away from Earth. The solar flux index remained in the range of 150 to 160 last week, which was enough to make the daytime maximum usable frequency remain above 28MHz most of the time, although the geomagnetic disturbance did have an effect and lowered it slightly. Next week NOAA predicts the SFI will remain in the range of 145 to 165. A geomagnetic disturbance is predicted for the fifth to the seventh, which could see the Kp index hit five. So, watch out for visible aurora once again. The period between the ninth to the fourteenth is predicted to be generally calm geomagnetically, so this might be the best time for DX on the upper HF bands. However, as we know this is a difficult time for predictions, anything could happen. We suggest keeping an eye on solarham.net for updates.   And now the VHF and up propagation news The very strong high pressure and tropo enhancement recently have. competed for attention with magnificent auroras, but we are now heading into quieter territory. The large high will decline early this weekend, ending the tropo bonus. After which, the central weather theme is that of a colder northerly weather type with wintry showers, especially near windward coasts. This raises the prospect of rain scatter on the GHz bands. After the recent dramatic solar-induced propagation week, it would be optimistic to expect a repeat, but the spring months are notable for producing auroras and there is always random meteor scatter. So, there are plenty of options to check up on in the coming week. For EME operators, Moon declination is still high this weekend but we are on a downward trend, turning negative on Thursday, meaning Moon availability windows shortening all week. With perigee last Friday, path losses will continue to fall. 144MHz sky noise is low all week. Perhaps you already view your radio-activity in the context of propagation conditions. But, for those not yet making this a routine, becoming aware of how these things are controlled can make a huge difference to your operating successes. Why not start by seeking out some of the excellent propagation talks from radio clubs and the RSGB Convention which are often available online? And that’s all from the propagation team this week.

Using CW and SSB, the exchange is signal report, serial number and Worked all Britain square, if applicable.  Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 23rd of February 2023 Last week was characterised by many low- and medium-level solar flares. At the time of writing, in the past seven days, the Sun has emitted more than 60 C-class flares, six M-class flares and one X-class flare. The X-class flare coincided with the measurement of the solar flux index meaning an erroneous reading of 343 was logged. The next day it was back to a more accurate 167. The solar flux index has generally declined from the 200s we saw earlier in the month and stood at 152 on Thursday the 23rd. Nevertheless, daytime maximum usable frequencies over a 3,000km path still exceed 28MHz on a daily basis. Geomagnetic conditions have been mixed with the Kp index hitting 4.67 on Thursday due to a fast solar wind. We are heading towards the equinox period as we leave February next week and enter March. This is a time that favours North/South paths, such as the UK to South Africa and the UK to South America. We’ll start to lose propagation to the USA on the higher bands as the Spring progresses, but don’t worry – it will be back in the Autumn! A coronal hole is turning into an Earth-facing direction, which may cause some disruption with an increasing Kp index this weekend. NOAA also predicts slightly worse conditions for the next week with the solar flux index declining to the 125-145 range. Unsettled conditions are predicted for the period of the 5th to the 7th of March, with the Kp index perhaps hitting five again. As always, this is a guide as we are living in unpredictable times with regard to solar activity. And now the VHF and up propagation news The coming week looks likely to be another high-pressure period on the weather charts. As we ended this week, the high was offset to the west of Ireland but will become centred over Scotland with a colder north easterly over southern Britain. This means that Tropo may become a mode of choice, particularly for northern areas, although this may well decline as a colder northerly starts at the end of next week. This could offer rain or snow showers with the chance of some associated GHz band scatter propagation. As secondary options, aurora and meteor scatter remain viable, of course. Watch for a high Kp index for aurora and remember that random meteor scatter is always likely to be best around dawn. For EME operators, the positive and rising Moon declination this week will see Moon availability windows lengthening until maximum declination on Wednesday. So, there will be high moon elevations, but path losses will continue to increase until apogee next Friday when the path loss trend will reverse. 144MHz sky noise is moderate to low for the rest of the week, only reaching 500 Kelvin on Tuesday and Wednesday. And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for February 19th 2023

GB2RS News Sunday the 19th of February 2023 The news headlines: RSGB Board Chair and Company Secretary RSGB Unopposed Election Results Saint Patrick's Day Award   We report with regret that Richard Horton, G4AOJ has tendered his resignation as an RSGB Board Director and the Board Chair, and Stan Lee, G4XXI has tendered his resignation as RSGB Company Secretary. The resignations are independent of each other and for personal reasons. The RSGB would like to thank them for their hard work and contribution to the Society. The RSGB President Stewart Bryant, G3YSX will Chair the Board until the AGM. In view of the important role of the Company Secretary in the Society’s AGM, which is just a few weeks away, the Board will agree to the appointment of a temporary Company Secretary pending the advertisement of the position and selection through the normal process. The RSGB has announced the unopposed nomination results in its 2023 elections. In the election for RSGB President, there was only one nomination received so John McCullagh MBE, GI4BWM is elected unopposed for a two-year term. This year there were Regional Representative vacancies for five Regions – Regions 3, 7, 8, 11 and 13. The only candidate for Region 8 was Michael Na bPiob, MI0HOZ so he is duly elected unopposed for a three-year term. The terms of office for both roles above will commence at the AGM on the 15th of April 2023. You can read their personal statements on page 6 of the March RadCom or on the RSGB website at www.rsgb.org/election The RSGB would like to congratulate both candidates and wish them well in their roles. RSGB Board Director candidates will be announced in the April RadCom and voting will begin on Wednesday the 15th of March. There are just over three weeks left to register to participate in the annual Saint Patrick's Day Award. The event takes place over a 48-hour period from 1200UTC on the 16th of March to 1200UTC on the 18th of March to allow worldwide participation in all time zones. The Saint Patrick's Day Award is 48 hours of non-competitive fun. Everyone can participate in the event, whether they are licensed or not. You can register to be a participating station by completing a short registration form online at stpatricksaward.com The Isle of Man Amateur Radio Society will be operating the club callsign GT3FLH from the Isle of Man Sea Terminal building in Douglas on Saturday the 25th and Sunday the 26th of February between 11 am and 3 pm.

An impulsive X1.1 solar flare was observed around active region 3217 in the southeast quadrant of the Sun at 1548UTC on the 11th of February. The flare did not appear eruptive, so we had no associated coronal mass ejection. Nevertheless, the flare caused a fade-out as its X-rays penetrated deep into the D-layer of the ionosphere. There were other lesser M-class and C-class flares throughout the week. The Kp index rose to five on Wednesday the 15th of February and conditions continued to be geomagnetically unstable throughout Thursday. Nevertheless, the ionosphere remained relatively stable with daytime MUFs over 3,000km generally staying above 28MHz all week. The critical frequency is generally remaining well above 4MHz until midnight, meaning 80m is open around the UK and also to DX. After midnight it can decline, meaning only longer paths are open. NOAA has updated its coronal mass ejection forecast model to predict a stronger-than-anticipated solar wind passing Earth by late Friday the 17th of February and into Saturday the 18th. A moderate G2 level storm watch was officially added, beginning on Friday, so aurora sky watchers and VHF enthusiasts should be alert this weekend. Next week, the Space Weather Prediction Centre forecasts that the SFI will fall back, perhaps to 130 by next Friday. Once we get past this weekend’s geomagnetic disturbance, the Kp index is predicted to remain settled all week, although a single coronal mass ejection could soon spoil that.   And now the VHF and up propagation news After some good tropo for the 70cm UK Activity Contest last Tuesday, it will be a return to more unsettled weather that ends this week and starts this weekend. High pressure will then quickly return and take up residence over the south and west of the country, eventually ending up west of Ireland.  This will mean that tropo will again offer some enhanced conditions on VHF and UHF and may prove useful for the 1.3GHz UK Activity Contest on Tuesday evening. After midweek, it will tend to favour paths within the UK and to the south into France. From midweek there will be low pressure to the east of the British Isles with a showery northerly flow down the North Sea. This will cut off the eastern half of Europe from any Tropo prospects, but it may offer some rain scatter from eastern areas. There may continue to be some good chances of auroral propagation, which you
