The news headlines:

The RSGB has announced the details of the amateur radio activity that it provided for the British Science Week 2025 Community PackNominations encouraged for the role of RSGB PresidentThe next Tonight@8 webinar will focus on fault finding in construction projects

The RSGB is delighted to announce details of the amateur radio activity that the Society provided for the British Science Week 2025 Community Pack. The RSGB Outreach Team, working with the RSGB Comms Team, submitted two activities on this year’s theme of ‘Change and adapt’ and one was chosen for the Community Pack. This activity was created by John Hislop, G7OHO and tested by RSGB School Youth Champion Chris Aitken, MM0WIC, and other members of the Outreach Team with various groups and ages. It uses amateur radio to find out if people in different countries are seeing changes in their weather patterns. It is a simple activity that is also designed to get people on the air. Community or youth groups will need access to a Digital Mobile Radio repeater and assistance from a radio amateur, which is why the RSGB is asking for the support of the amateur radio community to make this as effective as possible! You can find the RSGB activity and other resources on its website at rsgb.org/bsw so take a look and get ready to be involved! You can also find the full set of this year’s activity packs at britishscienceweek.org To ask questions or suggest an activity, contact the RSGB British Science Week Coordinator Ian Neal, M0KEO via [email protected].uk

The RSGB President is a prestigious and important role. Each President has the autonomy to shape the duties and activities they carry out to best match their view of the role. Former Presidents have spoken of the unique insight it has given them into the hobby, and the fulfilment they have felt from the role. Read more from the current and some previous Presidents by going to rsgb.org/president If you believe you can advocate for amateur radio, that you have the necessary understanding of how the RSGB works, and are someone who can relate to and talk engagingly with a wide range of people, then why not apply to be the next RSGB President? Nominations are now open in the RSGB 2025 elections and full candidate packs can be found via rsgb.org/election Applications are strongly encouraged from radio amateurs of all different backgrounds and identities. Every new volunteer who joins the RSGB is an opportunity to bring a different perspective, which the Board is eager to embrace. Remember that the closing date for all vacancies is 2359UTC on the 31st of January. So, if you’d like to rise to the challenge and be the Society’s next President, act now.

Have you ever spent time constructing a project, only to find it doesn’t work? If so, the next Tonight@8 webinar on Monday the 3rd of February is one to put in your diary. Lee Aldridge, G4EJB will present a basic fault finding and electronics session that will look at the requirements of construction, as well as the pros and cons of different types of construction. He will also look at what to do when you’ve built a project, but it doesn’t work. This will include looking at your method, understanding some simple circuits and basic use of a digital multimeter, your expectations, as well as checking and testing. Lee has nearly 35 years experience of working in telecoms and electronics and will be known by many as the former RadCom Basics Editor. Find out more about this discussion by going to rsgb.org/webinars Watch the presentation live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 23rd of January 2025

This week, ending today the 26th, has looked a lot like a repeat performance of two weeks ago. The majority of the sunspots are in the western hemisphere with very few in the eastern side. This means that the solar flux index could drop over the coming week unless there are sunspots ready to rotate into view to replace those being lost.

A look at the STEREO Ahead spacecraft imagery suggests that there are indeed sunspots over the Eastern limb, so all may not be lost.

Overall, the Sun has been fairly quiet. There were no X-class flares and only five M-class flares from the 19th to the 23rd of January. The Kp index has also been relatively low, only peaking at four for one three-hour period on the 20th of January.

As a result, with the solar flux index in the 200s, HF conditions have been quite good. The maximum usable frequency over a 3,000km path has been consistently over 28MHz, from around 0830 to 1600 UTC. However, the 20, 17, 15 and 12m bands, seem to be carrying most of the DX at the moment.

Next week, NOAA predicts that the solar flux index will remain in the mid-200s. Geomagnetic conditions are also predicted to be good until the end of the month, but a Kp index of 5 is forecast for the 31st of January, and this could last for a few days.

So, we urge you to make the most of the conditions now, before geomagnetic storming, if it occurs, makes a mess of HF as we enter February.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather pattern is being driven by a very strong winter jet stream across the Atlantic Ocean. This gives scope for rapid development of deep lows and consequent gales and damaging winds.

On Friday the 24th of January, the first big storm hit the northwest of Britain. We may find that the next low in the series is heading for southern Britain tomorrow, the 27th.

This all makes tropo unlikely for much of the week ahead since it stays unsettled through most of the period but with the smallest hint of higher pressure trying to return from Thursday.

Rain scatter will probably be worth some consideration on the GHz bands while meteor scatter remains driven by random activity rather than any major showers.

There have been further aurora alerts over the last week and it's always worth keeping the Kp index in view to monitor any possible chances for aurora. High figures, above a Kp index of 4, are a good trigger point to get interested.

Moon declination reaches a minimum in the northern hemisphere today, the 26th, when Moon windows are at their shortest and peak Moon elevation is at its lowest.

Path losses are now falling as we passed apogee on Tuesday the 21st. 144MHz sky noise is high, reaching over 3,000 Kelvin today, the 26th, before dropping to moderate until Wednesday when the Moon and Sun are very close in the sky for the whole Moon pass. After this, it drops to a low for the rest 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 17th of April 2025
Last week was characterised by increased Kp index numbers and severe geomagnetic storms, peaking at G4. These drove down maximum usable frequencies and disrupted DX contacts, especially on the higher HF bands.
The solar wind speed increased from 380 kilometres per second to around 500 kilometres per second on the 15th and an increase in plasma density was noted as well. Subsequently, the Kp index peaked at 7.67 on Wednesday the 16th, causing visible aurora alerts in the UK.
This was caused by a pair of CMEs that left the Sun on Sunday the 13th of April. We had a total of 22 M-class solar flares over four days, so a CME event was inevitable.
Unsettled geomagnetic conditions are a feature on the declining side of a solar cycle, so we could unfortunately be in for many more.
According to Propquest, MUFs over a 3,000km path fell to below 18MHz for long periods on Wednesday the 16th, before climbing to around 21MHz at the end of the day.
Meanwhile, the solar flux index fell from a high of 170 on Friday the 11th of April to a low of 148 on Wednesday the 16th of April.
Next week, NOAA predicts that the SFI will start the week around 145 but could increase to 165 as the week progresses. Unsettled geomagnetic conditions are forecast for the 22nd to the 24th of April, with a predicted maximum Kp index of four.
As always, keep an eye on solarham.com for daily updates, but more importantly, get on the bands, which are a much more effective guide to HF propagation!
And now the VHF and up propagation news from G3YLA and G4BAO
The current period of unsettled weather looks likely to continue into the coming week. This does not mean rain every day, but periods of rain or showers with some intervening drier spells. These drier interludes are not really dominated by high pressure, just gaps between the wetter periods, so it's unlikely to produce much significant Tropo.
In terms of propagation, there may be some rain scatter, although it won’t be very reliable. However, the prospects for meteor scatter are more promising with the peak of the Lyrids due on Tuesday the 22nd of April. It is worth checking up on procedures for meteor scatter working if you’ve not done it before and you may find a new part of the hobby to add to your operating schedule.
The prospects for aurora continue to be raised by what seems like an almost daily supply of aurora alerts. Continue to monitor the Kp index for signs of elevated values, where Kp is above five, for radio activity. Early signs such as fluttery signals on the LF and HF bands may suggest it's worth looking on the VHF bands for auroral activity.
As we move towards the new season it is good to get into the habit of looking for Sporadic-E. The Propquest website www.propquest.co.uk shows several useful components for analysing the Es prospects. If you look at the position of the jet streams shown on the Es blog tab, these can produce favourable conditions geographically to give a hint of the right direction in which to listen. The opening season typically favours 10m or 6m.
EME path losses are now decreasing towards perigee on Sunday the 27th of April. Last Friday, the 18th of April, saw minimum Moon declination, so Moon windows will lengthen along with peak elevation. 144MHz sky noise starts this week very high but decreases to low as the week progresses.
And that’s all from the propagation team this week.

The RSGB is looking to recruit volunteers from the exam tutor community to help pre-screen documentation prior to public release as part of the process of improving the quality of documents issued by the Exam and Syllabus Review Group (ESRG). The Exam Tutors Review Panel is intended to be an informal group of approximately six tutors who are currently involved in providing training for amateur radio licence exams at any of the three current levels. Panel members will be asked to use their skills to help improve the quality of the syllabus, the questions in the published question bank and other published documentation. They will receive advance copies of documents that are due to be published, and they will be expected to return any comments within an agreed timescale, which typically will be two weeks. The ESRG is not obliged to accept the recommendations from panel members, but if they do not accept a recommended change, they will explain why. All documents and additional correspondence sent to panel members will be under an embargo until the final versions are released to the public. The Exam Tutors Review Panel is intended to run for an initial six months and will then be reviewed. If you are interested in becoming a member of this panel, please email Board Director Len Paget, GM0ONX via [email protected].uk

Now the contest news
On Tuesday the 15th of April, the 1.3GHz UK Activity Contest runs from 1900 to 2130UTC. Using all modes on the 23cm band, the exchange is signal report, serial number and locator.
On Wednesday the 16th of April, the 80m Club Championship runs from 1900 to 2030UTC. Using SSB on the 80m band, the exchange is signal report and serial number.
On Thursday the 17th of April, 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 April 2025
A fast solar wind caused some disruption last week, often sending the Kp index up to five, with many three-hour periods in excess of four.
The solar wind speed was in the 600-700 kilometres per second range, which caused a moderate, G2, geomagnetic storm and visible aurora at higher latitudes mid-week. Glancing CMEs that left the Sun on the 9th of April brought a small chance of enhanced geomagnetic activity at the end of the week.
Meanwhile, the solar flux index declined slightly from a high of 184 on the 5th of April to 167 on Thursday the 10th. There have been quite a few C-class solar flares, but only two M-class flares and no X-class events over the past seven days.
This geomagnetic activity has taken its toll on HF propagation, with lower critical frequencies at times and lower MUFs. This, coupled with the start of a change to summer ionospheric conditions, has meant that MUFs over a 3,000km path have often struggled to get past 19.7MHz at times.
We have probably seen the best of the long-range 10m propagation until the autumn. But we will have Sporadic-E and its associated short skip from next month to make up for it.
Next week NOAA predicts that the solar flux index will fall further, perhaps to between 135 and 140 by the 15th of April. Geomagnetic conditions are also likely to improve with a Kp index of two to three, forecast for the period after tomorrow, the 14th of April. We may expect more problematic geomagnetic conditions, with a predicted Kp index of four, from the 21st to the 24th of April.
And now the VHF and up propagation news from G3YLA and G4BAO
The long spell of fine settled weather and strong Tropo is leaving us for a while, starting this weekend, and the high pressure is giving way to slow-moving areas of low pressure with cloud and rain for the coming week.
Although it won’t rain all the time it will be considerably wetter than recent weeks, with some heavy spells of rain at times and good prospects for rain scatter on the GHz bands. It is possible that there could be some thunder in the heavier rain, so it’s now the season to be aware of lightning risk.
The meteor scatter prospects are staggering towards the 22nd of April Lyrids, which peak on Tuesday of the following week, so we’re still probably relying on random activity for most of this coming week, but with improving chances.
The solar conditions have been feeding low-level auroral activity and it remains a good time of the year when some effective auroral conditions can appear - so stay alert to the state of the Kp index, just in case.
The good news at this time of the year is that Sporadic-E will eventually make an appearance, usually on 10m or 6m, and is quite often first picked out on the digital modes. It will be into late April before we need to get too excited about this, but there is no harm in getting a set of beacons in mind for tracking an opening.
Remember the main characteristic of Es is that it starts on the lower frequencies like 10m, and works up through 6m to 4m and then finally 2m in a high-summer opening.
EME path losses are at their maximum at apogee this evening, the 13th, and Moon declination is negative and falling further. Moon windows will continue to shorten with peak elevation reaching only eight degrees at the end of next week. 144MHz sky noise starts the week low but will increase during the week to more than 2300 Kelvin on Friday.
And that’s all from the propagation team this week.

The news headlines:
Last chance to submit your question ahead of Saturday’s RSGB AGMTom Wardill, 2E0JJI has been appointed as RSGB Maker ChampionReduced exam slots over Easter weekend
The RSGB 2025 AGM is taking place at 10 am next Saturday, the 12th of April. The Society is encouraging RSGB members to take the time to vote for the two resolutions that need your approval. During the AGM, Board members will be answering your questions. Whether your question is about the RSGB, the Board, any of the RSGB services or even the future of amateur radio, your contribution to the discussion is important. Priority is given to questions submitted live by Zoom or by the Society’s web form, so get in touch now rather than waiting for the live chat option on the day. The Zoom question deadline is 9 am on Monday, the 7th of April, and the deadline for submitting a written question is when voting ends at 0900 on Thursday, the 10th of April. Following the formal business of the AGM, the RSGB is delighted that RSGB President John McCullagh, GI4BWM will be sharing his review of 2024. There will also be announcements of trophies and awards, the construction competition results, as well as a presentation about the Society’s strategy, which will be led by Board Director Mark Jones, G0MGX. There will be contributions from Board Director Ben Lloyd, GW4BML; Spectrum Forum Chair Murray Niman, G6JYB; and Bob Beebe, GU4YOX who at that point will be the new RSGB President. Make sure you don’t miss out by putting the date in your diary now. Go to rsgb.org/agm to find further information.
The RSGB is pleased to announce that Tom Wardill, 2E0JJI has been appointed as the RSGB Maker Champion. In his role, Tom will assist the RSGB to take amateur radio to new audiences in the hackspace and makerspace communities. Tom will also investigate opportunities to encourage crossover in both directions, offering new areas of experimentation to more traditional license holders. If you have any ideas you’d like to discuss with Tom or would like to congratulate him on his appointment, please email him via [email protected].uk
A reminder that the RSGB remote invigilation team will be taking a break over the Easter weekend. You will be able to book to take an exam on Friday, the 18th and Saturday, the 19th of April; however, no exam slots will be available on Sunday, the 20th or Monda,y the 21st of April. Exam bookings will resume as normal after that.
The next webinar in the RSGB’s Tonight@8 series will be live tomorrow, Monday the 7th of April. Nick Wood, M0NTV will show you how to use a regular glue stick housing in a rather novel way to form the basis of a variable tuning inductor in a homemade 40m receiver. Nick has a lifelong fascination with radio and electronics, and an insatiable curiosity to discover how things work. His passion is for designing and building his own radio equipment, particularly SSB transceivers, and he has just completed his sixth. Visit rsgb.org/webinars to find out more. Join the presentation live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat.
The GB3WR VHF Repeater, located on the Mendip Hills in Somerset, was switched back on at 12:30 pm on the 16th of March 2025. The Group is delighted to report that it is working as well as before. It covers a wide area of the South West, and the Bristol Channel area. Amateur stations are regularly heard from the south of the Midlands, South Wales and as far south as Swanage and Basingstoke to the east. The Mendip Repeater Group would like to express its thanks for the generosity of all who have made it possible to put GB3WR back on the air. Find out more via gb3wr.uk

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 3rd of April 2025
We had a week of mixed solar conditions, but it ended with an SFI of 182 and a Kp of 3.67 on Thursday, the 3rd of April.
The geomagnetic field declined to quieter levels following a prolonged period of active, Kp4 conditions earlier on Wednesday due to solar wind enhancements. This impacted propagation, with the critical frequency struggling to get much above 7 MHz on Wednesday.
Compare this with the following day, when the critical frequency hit 10.4MHz by 0830 UTC. Nevertheless, there was DX to be worked on Wednesday with FT8 allowing signals from Australia, Japan, Indonesia, China, and Surinam to get into the UK on 21MHz.
The solar proton flux was also high on Tuesday, the 1st of April, affecting signals passing through the polar regions, but this had declined by Thursday and was heading back to normal levels. This was due to a large CME observed off the east limb of the Sun on Frida,y the 28th of March. If it had been Earth-directed, we may have seen a massive aurora.
Next week, NOAA predicts that the solar flux index will stay in the 175-185 region. A Kp of six was forecast for yesterday, Saturday the 5th of April, followed by a further period of unsettled geomagnetic conditions due to an enhanced solar wind.
If this is the case, we may not get more settled conditions until the 14th to the 16th of April.
Nevertheless, this remains a good time for North-South HF paths, such as the UK to South Africa, and UK to South America.
And now the VHF and up propagation news from G3YLA and G4BAO
The old forecasting maxim that the ‘longer a high lasts, the longer it will last’ is built upon the presence of blocked upper air weather patterns. When the jet stream gets so distorted into a high-amplitude north/south wave, its lateral movement, from west to east, becomes very slow.
On the upper air charts, this takes the shape of the Greek letter omega, and this is the current set-up. It means that the weather associated with it also lasts a long time.
In this case, it’s the high pressure and its spell of fine weather that is likely to last for the whole of the coming week. The position of the high will change, though, starting over the North Sea and ending over the UK and the nearby Atlantic. This means that Tropo will be the mode of choice for the coming period, which includes the 70cm UK Activity Contest on Tuesday and the 6m UK Activity Contest on Thursday.
Rain scatter is unlikely during this extended period of dry weather.
The meteor scatter options are still mainly driven by random meteors for the coming period into next week, but the next important shower, the Lyrids, peaks on the 22nd of April. The auroral alerts continue to come through, raising interest. As usual, the clue will be fluttery-sounding signals on the bands, particularly noticeable on CW, but they can also be pronounced on speech transmissions. Monitor the Kp index for values above Kp5.
There have been a few trans-equatorial openings to Southern Africa on 50MHz digital modes for the fortunate few who live in the extreme south and southwest of the UK, but it did extend up to Cambridgeshire and Suffolk briefly on some days last week.
The long drought of Sporadic-E will soon be over, but we’re still in the realms of very isolated events for 10m and 6m, which will be short-lasting. The jet stream, which can be a good clue as to potential locations, suggests looking to Scandinavia, the Baltic and northern Europe.
EME path losses are falling again, but Moon declination has been at its highest this weekend, so we have long Moon windows. 144MHz sky noise is low throughout the coming 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 27th of March 2025
Last week’s space weather was dominated by a large coronal hole on the Sun. This was probably one of the largest we have seen for many years.
Moderate, G2, geomagnetic storming was observed following the arrival of a solar wind stream from the hole, with the wind speed exceeding 600 km/s on Wednesday, the 26th. This pushed the Kp index to 6.33, depressing the MUF slightly.
Luckily, the daytime MUF over a 3,000km path mostly stayed above 28 MHz, but it was slow to rise on Thursday, the 27th, when it took until 0900 UTC to reach 28 MHz. At the time of writing, the solar wind speed was more than 800km/s, so we can expect more disruption until at least Saturday, the 29th.
Meanwhile, the solar flux index declined to 152 by Thursday, the 27th, with only four small sunspot regions visible.
CDXC members have been discussing working New Zealand in the morning at the ZL sunset, often on low power. Listen and look for ZL4OL and ZL2CC, usually on FT8, but if conditions allow CW and SSB. 20m or 40m seems to be the favourite, and the VarAC data mode seems popular in ZL as well.
Next week, NOAA predicts the solar flux index will climb again, perhaps to 180 by the 4th of April. However, unsettled geomagnetic conditions are forecast again, beginning on the 3rd. We may expect the Kp index to reach six, which could be the start of at least ten days of disruption.
And now the VHF and up propagation news from G3YLA and G4BAO
The overall picture for the weather patterns in the coming week is that of high pressure, which means that Tropo should be available as a good mode for VHF bands.
There can be quite strong temperature inversions in the region of large well-developed areas of high pressure. The best performance will usually be around the edges of the high where the height of the inversion and ducting layer is typically between 0.5km and 2km above the ground, and can cover large distances for excellent DX prospects.
Occasionally, a shallow ducting layer can form near the ground overnight but often disperses by mid-morning. If you are in a good inversion region, try SSB or CW on the VHF/UHF bands, as paths of up to 1,500km can often be achieved from a good ‘tropo lift’.
The reverse side of the high-pressure systems is that we will have low pressure nearby, mainly to the north and west of the UK. Any potential for rain scatter will mainly be over northwestern Britain, although an active front that was moving south on Friday, the 28th of March, was a good candidate for chance rain scatter on the GHz bands.
The prospects for meteor scatter are still largely dependent upon random meteors, which are usually best in the hours before dawn. Current solar activity will continue to trigger auroral alerts in the coming week.
Now onto Sporadic-E, and last week we had a few out-of-season isolated foEs ‘blips’ to between 5- 7 MHz, which was enough to produce propagation on 10m and 6m, albeit very fleetingly.
There have already been some equinox-related 6m trans-equatorial propagation or TEP workable from the Southern part of the country, so keep an eye open late morning for Africa and late afternoon for South America.
EME path losses have continued to improve until perigee this morning, the 30th of March. Moon declination is still falling, and reached a minimum last Friday, the 28th. Moon windows will increase throughout the coming week. 144MHz sky noise is low, apart from Saturday the 29th when the Sun was close to the Moon in the sky, rising to moderate next Thursday before dropping back to low for the weekend.
And that’s all from the propagation team this week.

The RSGB is excited to give you a first look at its new app! The web version has just been launched and is a one-stop shop for all RadCom publications and club newsletters. You can find the web version at rsgb.org/radcom It gives RSGB members easy access to over ten years of back issues of RadCom, as well as RadCom Basics and Plus. The Society will be adding more back issues of RadCom from the archive in the coming months, making it even more valuable. All you need is your RSGB membership portal details to access the editions. If you’re not an RSGB member, you can still view a sample edition of RadCom through the web version of the app. If you like what you see, you can become an RSGB member via rsgb.org/join which will give you access to the back issues of RadCom and its sister publications. Watch this space for news of the release of the RSGB mobile app later this year.
For some roles in the RSGB elections, a single nomination was received. These include the two vacancies for Elected Board Directors. Peter Bowyer, G4MJS and Mark Savage, M0XIC will each take up the role of Board Director at the end of the RSGB AGM on the 12th of April 2025. Both were interviewed separately to enable RSGB members to hear their views on the current issues facing amateur radio and the Society. Their answers were combined into two videos: the first ‘short’ video is just two quick questions, and the second video is a more in-depth interview. You can watch them both on the RSGB website and its YouTube channel. For more information about each of these unopposed candidates, see the April 2025 issue of RadCom or go to rsgb.org/candidates
The RSGB 2025 AGM will take place at 10 am on Saturday the 12th of April. The event will be held online to ensure that 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 and details about the election. The RSGB President John McCullagh, GI4BWM will give a video review of 2024, and the Society will announce the recipients of its annual awards and trophies, as well as the winners of its construction competition. You can ask the Board questions on the day via Zoom or the YouTube live chat, or by submitting a written question in advance. After the main AGM meeting, the RSGB is delighted to have a presentation about the Society’s strategy. Led by Board Director Mark Jones, G0MGX, there will also be contributions from Board Director Ben Lloyd, GW4BML; Spectrum Forum Chair Murray Niman, G6JYB; and Bob Beebe, GU4YOX who will at that point be the new RSGB President.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 20th of March 2025
Last week was pretty unremarkable from an HF perspective. After the disturbed geomagnetic conditions on the 12th to the 14th when the Kp index rose to five, conditions were a little more settled.
The solar flux index hit 204 on the 17th of March but then declined back to the 180s.
Having said that things were settled, the Kp index did exceed four for three periods on the 19th, peaking at 4.67. This had the effect of reducing the MUF over a 3,000km path to 21-24MHz.
We also had two M-class solar flares on the 17th and the 19th, with the latter causing a coronal mass ejection that may give Earth a glancing blow around the 22nd of March.
As spring progresses, we may find the F2-layer MUF dropping as we move to summer ionospheric conditions, perhaps to be replaced by enhanced sporadic-E conditions on 10 metres instead.
Next week, NOAA predicts that the solar flux index may drop further, perhaps hitting 150 on the 28th. Unsettled geomagnetic conditions are forecast for the 25th to the 28th, with a maximum Kp index of five.
As we said last week, this is now a peak period for auroral activity, given the angle that the Earth makes with the Sun. The 'Russell-McPherron' effect is down to the alignment of the Sun and Earth around the spring and autumn equinox and means that you are twice as likely to experience the aurora in spring and autumn than in winter and summer.
And now the VHF and up propagation news from G3YLA and G4BAO
The recent fine weather has provided some useful Tropo. This has been mainly towards the east and into the near continent, which seemed like nice timing for the 1.3GHz UK Activity Contest last Tuesday evening.
Despite this, many participants reported conditions as poor. The high is now moving away and by the time you hear this, it will be a predominantly low-pressure weather sequence from now on. This means limited Tropo in the coming week, and rain scatter comes to the fore as a mode of choice if you have a GHz band set up.
The solar conditions continue to provide a trickle charge of auroral alerts, but not enough for any significant operating advantage. As usual the message is to keep on top of things by monitoring the Kp index for values over 5.
Meteor scatter remains largely in the gift of random meteors, so it's an early start to catch the pre-dawn peak of random meteors if you are so persuaded.
Lastly, a mention of Sporadic-E which is still in its close season. We have a while to wait until later next month when we could expect the occasional stirrings on 10m.
EME path losses continue to improve until the Moon’s perigee (its closest point to Earth) on the morning of the 30th of March. Moon declination has been falling, reaching a minimum yesterday, the 22nd.
So again, we have short Moon windows and reduced peak Moon elevation. 144MHz sky noise started high on Friday the 21st of March but will drop back to low by the middle of next 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 13th of March 2025
We’ve had another week of disturbed geomagnetic conditions with the Kp index at four or five for long periods. On the evening of the 12th of March, Kp was five and, at the time of writing, has stayed there for a total of five three-hour periods.
This has taken its toll on the ionosphere with MUFs over a 3,000km path down to less than 24.7MHz during daylight.
Meanwhile, the solar flux index rose to 160 on Thursday the 13th after hitting a low of 147 on the 7th.
The best HF propagation was last weekend, the 8th and 9th of March, just in time for the Commonwealth Contest. This saw stations around the world romping into the UK, including signals from Australia, New Zealand, the Falkland Islands, Barbados, and many others.
As contacts were limited to Commonwealth countries, it meant the UK had little QRM to contend with and it was fairly easy to fill the log book on 40m to 10m.
Australia was still coming in at 59 after dark, and even British Columbia on the west coast of Canada could be worked with simple wire antennas and low power.
This may have been caused by a pre-auroral enhancement, as the Kp index rose late on the first day of the contest.
Next week, NOAA predicts the solar flux index may rise to 195 by the 21st. It also suggests that we may be back into calmer geomagnetic conditions with a maximum Kp index of two. This will be a welcome change and, if it happens, will no doubt result in better HF conditions.
And remember, March is a good month for north-south contacts, such as the UK to South Africa and the UK to South America.
But with the equinox just around the corner, auroras are twice as common due to the Russell-McPherron effect.
Just as when two bar magnets attract one another when they are oriented oppositely, so opposite Bz components attract. During the autumn and spring equinox, this orientation enables a 'connection' to the Sun, thereby allowing the solar wind to stream in.
And now the VHF and up propagation news from G3YLA and G4BAO
The recent change to colder weather brought showers and potential rain scatter to the second half of last week. But this weekend we have lost the showers and gained a large region of high pressure to bring a hint of Tropo.
It's not perfect, since in cold air highs like this, conditions are usually less than ideal, so don’t expect too much from this particular area of high pressure.
The high will last until midweek before it slips away into eastern Europe and, on its parting, may allow some moisture below the inversion and will improve the Tropo prospects briefly. The second half of the coming week will be dominated by low pressure and back to rain-scatter as an option on the GHz bands.
The solar conditions have continued to provide a few weak auroral alerts and it's worth continuing a watching brief on the Kp index for hints of activity; anything greater than a Kp of five is worth our interest.
Listen out for watery-sounding signals on the LF bands and then check out the 10m and 6m bands for auroral signals.
The next important meteor shower is the April Lyrids, but there’s always the chance of random meteor scatter activity, particularly in the pre-dawn hours.
It’s still a little early to mention Sporadic-E, but it’s always worth looking at the lower frequencies first, which means 10m and 6m. Check the graphs on Propquest for signs of spikes in the foEs, which is the critical frequency of the Es-layer.
EME path losses continue to rise until apogee on Monday evening. Moon declination is still falling, reaching a minimum on Saturday the 22nd. So again, we have short Moon windows and reduced peak Moon elevation. 144MHz sky noise is moderate and rising to high by Friday the 21st.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 6th of March 2025
We started last week with geomagnetic disturbances that saw the Kp index rise to a maximum of 5.67 on the 28th of February and then hover around the 4.5 mark for the next couple of days.
As predicted, the rest of the week went quite well, with the Kp index in the range of one to four.
The solar flux index fell from a maximum of 210 on the 23rd of February to a low of 140 on the 2nd of March. It then climbed back to 160 on the 4th. Over the past week, we have had no X-class and only one M-class solar flare which was on the 5th.
As we head into next week, it looks like all the sunspots in the Sun’s northern hemisphere have now departed. Nevertheless, the southern hemisphere is still supplying lots of spots so don’t panic just yet!
HF conditions have been quite good. VK6IF and VK6IA in Western Australia were booming in on 28MHz USB on the morning of Thursday the 6th, as was VK9CU on the Cocos-Keeling Islands.
Nigel, VP8TXF and Ian, VP8CIW have been operating from the Falkland Islands ahead of this weekend’s Commonwealth Contest and have been worked from the UK on 20m-10m. They are there until the 10th, so get in quick.
Other DX to be worked this week includes VU4AX Andaman Islands, 6Y7EI Jamaica, PJ7AA Sint Maarten Island, 4S7KKG Sri Lanka, TY5C Benin, 6W7/ON4AVT Warang Senegal, RI1ANE Antarctica and H44MS Solomon Islands.
Next week, NOAA predicts that the solar flux index will start off around 150 and may then climb to 185 by the 16th. A large coronal hole became Earth-facing on the 6th, which may result in unsettled geomagnetic conditions this weekend, the 8th and the 9th.
It looks like we can expect unsettled geomagnetic conditions around the 10th to the 16th, with a maximum predicted Kp index of five.
And now the VHF and up propagation news from G3YLA and G4BAO
The weather divides into two segments; the first, from the middle of last week through to the middle of next week, is rather changeable with low pressure nearby bringing rain or showers and potential for rain scatter on the GHz bands.
Eventually, the unsettled weather ends with a cold northerly on Tuesday the 11th and this leads to a new high building from Wednesday into the weekend of the 15th and 16th March.
This is good news for Tropo and could possibly be of benefit to those in the UK 70cm Activity Contest on Tuesday the 11th in the western UK, but more generally for the FT8 70cm Activity Contest on Wednesday and the 50MHz UK Activity Contest on Thursday evening.
We are still between major meteor showers and therefore must rely upon random activity for now. The next shower of note is the Lyrids on the 21st and the 22nd of April, so we have a while to go yet.
The solar activity has continued to produce a regular supply of auroral alerts and fluttery signals on the LF bands, but with a lot of clouds in northwestern areas and southern parts just marginally out of reach for any naked-eye auroras. A few digital camera pictures did surface on the web.
Keep an eye open just in case though. Remember Kp equalling five or greater is where we need to be.
Lastly, the Sporadic-E prospects are still relatively low with only the odd minor blip up to around a Sporadic-E critical frequency of 5 to 7MHz, often around the middle of the day. This contrasts with the morning and evening windows in the main season. It is enough to promote interest in the 10 or 6m bands, but almost certainly a fleeting moment.
EME path losses rise all this coming week and moon declination falls with associated shortening Moon windows and reducing peak Moon elevation. The best results will therefore be early in the week. 144MHz sky noise is moderate this weekend, falling to low in the week commencing the 10th.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 27th of February 2025
We had another week of mixed geomagnetic conditions. The Kp index rose to a high of five with visible aurora over the UK at times.
Two large coronal holes are now both facing Earth. A solar wind stream flowing from these zones is expected to flow past Earth, possibly on Friday the 28th of February or Saturday the 1st of March. Active geomagnetic conditions with a Kp index of four are currently forecast for this weekend.
There has also been more solar flare activity over the past seven days with an X2-class flare on the 23rd and ten M-class flares. The X-class flare occurred at 19:27UTC so had little effect in Europe as the Sun had set. Luckily, an associated coronal mass ejection was not Earth-directed. Another fast-moving CME on the 24th was also not Earth-directed.
As we enter March it looks as though the Sun is still very active. The solar flux index stood at 180 on Thursday the 27th, after hitting 210 on the 23rd. Maximum usable frequencies over 3,000km are still reaching 34-35MHz around midday, while night-time MUFs are generally around 10-11MHz, with occasional openings on 20 metres.
This week Bob, VP8LP on the Falkland Islands has been active on 10 metres SSB and has been worked from the UK.
As we enter March this is a good time for North-South paths on HF, such as UK to South Africa and UK to South America. The spring equinox is also a good time for auroral conditions.
NOAA predicts the Sun will start next week with an SFI of 190, perhaps falling to 170-180 as the week progresses. We hesitate to say this, but geomagnetic conditions are predicted to be good once we get past the disturbances on the 28th and the 1st, but only time will tell!
And now the VHF and up propagation news from G3YLA and G4BAO
There is likely to be a welcome return of high pressure for much of the period from this weekend until the middle of the coming week on the 5th of March.
Models show a return of unsettled Atlantic weather, meaning lows, fronts, showers and rain scatter for the GHz bands. Until then, it will be typical high-pressure Tropo conditions with an extensive temperature inversion aloft caused by the descending warming air in the high-pressure region.
This should provide ducting conditions over a large part of the country. As often, the far north of the UK will probably just miss out and retain too much breeze for the inversion to be effective.
The lull in meteor shower activity continues, so once again your best chances will be in the morning hours around, or just before, dawn.
The Sun has kept aurora seekers busy and shows how frequently it can just tip into the right disturbed conditions at this stage of the solar cycle. As we said earlier, there have been reports of visible aurora in the past week.
The signs for this are the Kp index rising to five or greater and flutter on LF band signals or trans-polar paths on the HF bands.
The new Sporadic-E season is almost upon us, but we are not there yet. Check the graphs on Propquest for signs of enhanced foEs values and check the HF bands first; 10m is particularly good for strong European Es signals.
EME conditions will be predictable as usual, with Moon declination rising all week and path losses at their minimum at perigee late on Saturday the 1st of March. 144MHz sky noise is low from this coming weekend, rising to moderate by Friday the 7th.
And that’s all from the propagation team this week.

GB2RS News
Sunday the 23rd of February 2025
The news headlines:
The RSGB announces the unopposed candidates in its electionsThe RSGB releases 2025 Band PlansA year in numbers 2024 – some great things to celebrate!
Nominations in the RSGB elections have closed. For some roles, a single nomination was received, and the candidate is therefore elected unopposed. They will take up their role at the end of the RSGB AGM in April. These unopposed candidates include the roles of President and also Regional Representatives in Regions 1, 4, 7, 8, 10, 11 and 12. In Region 9, no valid nomination was received. For more information about each of these unopposed candidates, see the March issue of RadCom or the RSGB website at rsgb.org/election
The RSGB Band Plans for 2025 were published in the March 2025 issue of RadCom. They are also available on the RSGB website via rsgb.org/bandplans. This year’s plans incorporate further VHF and UHF changes in response to the increased demand that has been prompted by the new Ofcom amateur licence. There are also a few changes from the 2023 IARU Region-1 General Conference. All amateurs are reminded to consult the Band Plans before operating.
Despite continuing challenges nationally and across the world during 2024, the amateur radio community stayed strong and the RSGB supported it. The RSGB General Manager Steve Thomas, M1ACB wrote his annual feature called ‘A year in numbers’ for the March RadCom and shared some great things to celebrate, in which RSGB HQ staff often led the way. You can also see the highlights in a brief video on the RSGB YouTube channel. The April RadCom will show in detail the work of the committees and other specialist volunteers.
Girlguiding groups will be celebrating World Thinking Day on the Air this weekend so listen out for them and encourage the young operators. To highlight the opportunities for young people to get involved in amateur radio activities, this week the RSGB has published two new videos that celebrate the fantastic ISS contact and STEM day held in the autumn and attended by HRH The Duchess of Edinburgh. You can watch both the videos on the RSGB YouTube channel.
Between January and March 2024 Bob Bower, GM4DLG took on a one-man antipodean adventure. The DXpedition is currently being serialised in RadCom, and on Monday the 3rd of March, he will be delivering a Tonight@8 presentation to complement these features. The trip was eight weeks long and covered 27 activations from 11 sites on six islands. Bob operated on 20, 40 and 80m with 100W SSB into vertical arrays of his design, with his holy grail being a valid 80m greyline QSO with Great Britain. Visit rsgb.org/webinars to find out more. Join the presentation live on the RSGB YouTube channel or special BATC channel and ask questions via the live chat.
Don’t forget to submit your entry to the RSGB Construction Competition by Saturday the 1st of March. You’ll need to email a short description of your entry and up to four photographs. It is also recommended to send a link to a video that demonstrates your entry working. More details on submitting your application can be found via rsgb.org/construction-competition The results of the competition will be announced during the 2025 RSGB Annual General Meeting in April.
Exercise Blue Ham will take place on the 29th and 30th of March on the 60m band. Stations will be active between 9 am and 6 pm. Blue Ham exercises provide a platform to further develop Cadet radio operator skills and confidence by engaging with the amateur radio community via the MOD 5MHz shared band. Cadet radio operators, under supervision, will exchange radio messages with amateur radio operators in the UK and Europe. The Cadets hope to speak to many radio amateurs on the air. For more information visit alphacharlie.org.uk/exercise-blue-ham
The 26th European Hamradio School Stations Day will take place on Monday the 5th of May from 0700 to 1700UTC. This is an activity day, not a contest, so the focus is on personal radio contacts and QSO partners should take time for a short exchange. The organisers look forward to seeing many schools, universities and training centres on the air again. To find out more, go to tinyurl.com/european-schools
Please send details of all your news and events to [email protected].uk The deadline for submissions is 10 am on Thursdays before the Sunday broadcast each week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 20th of February 2025
It seems we were a little over-ambitious in suggesting that last week would be better for HF propagation. It looked like we would avoid coronal mass ejections and see the Kp index fall to lower levels.
Unfortunately, the Sun had other ideas and a fast-moving solar stream, often moving faster than 500 km/s, had a south-pointing Bz, which coupled more easily with Earth and sent the Kp index up to four or more.
So even by Wednesday the 19th, the Kp index was hitting five.
However it seems that the geomagnetic disturbance merely lowered the MUF from around 40-45MHz to 31-32MHz, so it barely affected HF propagation.
At the time of writing, there had only been one M-class solar flare in the past five days, but more than 50 minor C-class events. There were no Earth-directed CMEs.
Nevertheless, there was DX to be had with the standout stations being the V73WW DXpedition to Majuro Atoll on the Marshall Islands, TI1RRC Costa Rica, and 5N9DTG in Nigeria. Upcoming DX next week includes OX3LX (Greenland), Dave G4BUO as 5W0UO (Samoa), TO3Z (Guadeloupe), 4S7SPG (Sri Lanka) and FS/VA3QSL (St Martin).
Next week, NOAA predicts that the week commencing the 23rd of February could see the solar flux index starting at 170, but then rising to 195-200 as the week progresses. Geomagnetic conditions are predicted to start quietly, with a Kp index of two, but then become unsettled by the 27th to the 29th, with a maximum predicted Kp index of five.
If this scenario does pan out then we may expect the best HF conditions to occur at the beginning of next week, from the 23rd to the 26th.
As always, keep an eye on solarham.com for day-to-day solar news, and perhaps monitor PSKreporter, the Reverse Beacon Network and DX Clusters for digital, CW and SSB HF propagation updates.
And now the VHF and up propagation news from G3YLA and G4BAO
The current spell of unsettled weather seems likely to continue through to the end of next week. There will also be significant windy weather at times. It is therefore not a particularly good period for Tropo, or big antennas for that matter.
This leaves us with rain scatter on the GHz bands and some of these scattering regions will be large areas affecting the whole of the country as weather fronts pass by, rather than more isolated and harder-to-follow showers which often provide our rain scatter.
Meteor scatter is still within its quieter period with no major showers and better chances coming from random meteor activity, which tends to peak in the hours before dawn.
Recent solar activity has provided some weak auroral conditions on many days. As usual, check for high values of the Kp index as a good indicator, or even listen for a watery tone on the LF bands. Ultimately you will need to see the Kp index going to at least five to make it worth checking for auroral signals on VHF.
We are still in the dormant period for Sporadic-E propagation, which is a shame given the powerful jet streams likely during this stormy weather. These would produce good Es prospects in the main summer season, but weaker Es at low VHF are still a possibility despite being out of season.
Moon declination is at minimum today, Sunday the 23rd of February, and path losses are decreasing as the Moon moves closer to Earth as it heads to perigee on Saturday the 1st of March. 144MHz sky noise goes high this weekend, beginning Saturday the 22nd.
And that’s all from the propagation team this week.

GB2RS News
Sunday the 16th of February 2025
The news headlines:
The RSGB has announced its Scout, Cadet and Girlguiding Youth ChampionListen out for stations operating for World Thinking Day on the AirNew resources and ideas have been added to the RSGB British Science Week web pages
The RSGB is delighted to announce that Samuel McCutchion, M7UEL will be the RSGB's Scout, Cadet and Girlguiding Youth Champion. Sam brings a wealth of hands-on experience to the role having been part of the Scouts from a young age in Beavers and then working his way up to Network. He then progressed to become an Assistant Section Leader. This knowledge will help the RSGB Youth Team to engage and offer amateur radio support to not only the Scouts but also the Cadets and Girlguiding. If you’d like to congratulate Sam on his role, or if you have any ideas you think would be useful to share, email him via [email protected].uk
Lots of amateur radio stations are on the air this weekend and next weekend for World Thinking Day on the Air. Listen out for them and encourage the young Girlguiding members. You can find details of some of the active stations via rsgb.org/thinking-day but, if your station isn’t listed, please share details on the RSGB social media channels. The event aims to encourage Girlguiding members to make friendships with those in other units, using amateur radio as the means of communication.
Have you visited the RSGB’s British Science Week web pages yet? Two new worksheets have recently been added to inspire you to get involved and showcase amateur radio to new audiences. The activities were designed by the RSGB Outreach Team to fit in with this year’s British Science Week theme of ‘Change and adapt’. If you’d like to deliver these activities to schools or youth groups, the Society has sample lesson plans, risk assessments and a guide to contacting your local school available on its website. Remember that British Science Week isn’t just for younger audiences, it is open to all. If you’re looking for ideas to get your friends and family involved or a local community group, go to rsgb.org/bsw and visit the British Science Week resources page. There is a wealth of ideas available, from looking at the history of radio communications to building a sustainable system using only solar panels. If you have an activity planned for British Science Week, let the RSGB know by emailing the RSGB British Science Week Coordinator, Ian Neal, M0KEO via [email protected].uk Details of events taking place will be shared on the Society’s website.
The deadline for the RSGB Construction Competition is Saturday the 1st of March, which means you have less than two weeks left to submit your entry. The judges will be considering entries in six categories: beginners, construction excellence, innovation, software, antennas and outreach. To find out how to submit your application go to rsgb.org/construction-competition The results of the competition will be announced during the 2025 RSGB Annual General Meeting on the 12th of April.
If you are passionate about amateur radio and have some spare time to support fellow radio amateurs, why not become an RSGB District Representative? There are currently 12 vacancies across the United Kingdom, including in Belfast, Cambridgeshire and Lancashire. To find out if there is a vacancy in your region go to rsgb.org/volunteers and then get in touch with the Regional Representative of the district with the vacancy.
Amateur radio operators are reminded to take care when operating on the WRC-15 secondary amateur allocation at 5MHz. The UK still has no access to the full WRC-15 allocation. Despite requests, this seems unlikely to change in the foreseeable future. Whilst the UK is fortunate to have more generous licence conditions, these mustn't be put at risk by irresponsible operating in violation of the licence conditions, particularly in the 5358 to 5362kHz gap where there is no UK allocation. The RSGB website has detailed advice for operators, both for SSB and digital modes, on its rsgb.org/5mhz web page. Please take care not to transmit outside of the UK segments even if you hear other amateurs transmitting. Remember that signals heard may be coming from amateurs in other countries with different allocations.
The RSGB ARDF Committee is pleased to announce the return of the British ARDF Championships in 2025. The Championships will be held as a three-day festival in early April 2025. Entries open on the 1st of March and will remain open right up until the event itself. Further information and updates can be found at tinyurl.com/ARDF25

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 13th of February 2025
Two large coronal holes on the Sun’s surface have been spraying solar material towards Earth, pushing the Kp index to a high of 4.67.
The solar wind speed has been consistently higher than 500 kilometres per second and, with a south-pointing interplanetary magnetic field, the plasma has flooded into Earth’s magnetic field. There have been a few aurora warnings, but these have only been minor.
As a result, the ionosphere has not been too badly affected and daytime maximum usable frequencies over a 3,000km path have generally remained above 28MHz, with the odd dip towards 24MHz.
Coronal mass ejections have not made an appearance and there were only three M-class flares between the 9th and 13th of February.
Meanwhile, the solar flux index fell to the 150s and 160s last week.
Recent HF DX has included the V73WW DXpedition on the Marshall Islands, which has been worked from the UK, including on the 40, 30 and 20m bands using CW. The TX7N DXpedition to Marquesas Island in French Polynesia has just finished. It wasn’t an easy path, but it was worked from the UK on all bands from 30 to 12m using FT8, CW and SSB.
Next week, NOAA predicts that the solar flux index could rise a little, to be in the 180 to 190 range. Once Earth is free from the effects of the current coronal hole stream, we may expect the Kp index to retreat, perhaps to a maximum of 2.
So, DX next week could be quite reasonable but, as always, keep an eye on solarham.com for daily updates.
And now the VHF and up propagation news from G3YLA and G4BAO
The lingering high pressure just to the east of the UK is holding weather fronts over western Britain for the time being with any tropo benefits confined to eastern areas and being marginal at best.
During the coming week, changes will be slow but gradually a more determined push on the Atlantic fronts may bring them over most areas, except the extreme southeast of the country.
This will make rain scatter more accessible although the models suggest that the fronts are likely to become weaker. So, they will not be especially useful by the time they reach the southeast. Sporadic-E is in its quiet season now, as are the meteor scatter prospects, with no major showers in attendance until the spring Lyrids in late April.
Perhaps this quieter time is a chance to do some operating housekeeping. For example, you could update a list of nearby repeaters and beacons to help you track developing openings. Or maybe you could consider trying a new mode or band. Perhaps you could learn to use digital modes for meteor scatter. Maybe consider joining the increasing numbers trying CW on the 2m band.
Moon declination went negative again on Saturday the 15th and path losses are rising as the Moon moves away to apogee, its furthest point from Earth, on Tuesday the 18th. 144MHz sky noise is low for most of the coming week but goes high for the weekend of Saturday the 22nd.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 5th of February 2025
Last week went pretty much as predicted. The solar wind from a large coronal hole impacted the Earth on Saturday the 1st of February, pushing the Kp index to four. The hole was so large that the geomagnetic disturbance lasted until the early evening on Sunday.
Once the solar wind speed had dropped, things got back to normal and the Kp index has been in the range of 1 to 2 ever since.
The event appeared to have had little effect on HF propagation, with maximum usable frequencies over a 3000km path remaining above 28MHz during the daylight hours. So it looks like we dodged a bullet.
At the time of writing, we have had 21 M-class flares in three days.
A solar flare measuring M8.8 was detected around active region 3981, peaking at 0358UTC on the 3rd of February. This was the strongest flare yet from this region in terms of peak X-Ray flux. However, the flare itself was impulsive and was not the source of a coronal mass ejection.
Over the next week, NOAA predicts that the solar flux index could fall slightly to be in the 180 to 200 range. Make the most of the good propagation as we may be entering a period of unsettled geomagnetic conditions again from the 10th to the 17th of February. NOAA predicts that the Kp index could rise to a maximum of 5 on the 13th but is likely to be in the range of 3 to 5 over the seven days.
Part of this may be down to another coronal hole which became Earth-facing on the 6th of February. There is also a good chance that we could get an X-class eruptive flare from active regions 3981 or 3978, which could result in a coronal mass ejection.
We recommend you keep an eye on solarham.com for daily updates.
And now the VHF and up propagation news from G3YLA and G4BAO
High pressure during the second half of last week brought some useful tropo conditions. As this week, ending today the 9th comes to a close there are some wintry showers along North Sea coasts, which may produce some snow and rain scatter. However, this may be weakened by the nearby high pressure.
By the end of this week, ending today the 9th, there will be a change of weather pattern as the high, having now migrated to Scandinavia, leaves room for Atlantic weather systems to encroach from the west during the coming week. This could bring rain scatter possibilities to the western side of the country. These should be more useful than the eastern coast ones at the end of last week since the rain will probably be heavier and the fronts slow-moving.
This time of year is something of a desert for Sporadic-E propagation although look out for lesser events as a result of jet streams. You can track these on the Propquest website.
Keep a look out for auroras during the week beginning tomorrow, the 10th. The likelihood of M-class flares is around 85%, while the chance of X-class flares is approximately 20%. So keep an eye on the Kp index for any potential solar events that could cause auroras.
Next week, there are no major meteor showers. The next significant meteor shower, the Lyrids, will become active in April. Keep checking the pre-dawn period for random meteors.
Moon declination reached a maximum yesterday, Saturday the 8th. Path losses are still low but will increase throughout the coming week. This means that this weekend, ending today the 9th, should produce good activity for EME, especially on the GHz bands with long Moon windows and high peak Moon elevation.
144MHz sky noise is moderate this weekend, ending today the 9th, but falls to low for the rest of the coming 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 30th of January 2025
Last week was pretty unremarkable as far as the Sun goes, but it looks like that is about to change.
The seven days preceding Thursday the 30th were characterised by reasonably settled geomagnetic conditions, with a maximum Kp index of 3.67 and a solar flux index that fell from 205 on the 24th, to the 170s by the 30th. During this period there had been only four M-class solar flares and no X-class events.
Over the next few days, things could change. Two large coronal holes near the Sun’s equator threaten to upset the quiet conditions. As the solar material flows out it could cause the Kp index to rise, perhaps to 4, with reduced maximum usual frequencies and noisy conditions. But this will depend upon its associated Bz or interplanetary magnetic field.
If it is south-pointing it will couple more easily with the Earth’s magnetic field, allowing plasma to flow in, and the Kp index will rise. However, if it is north-pointing we may see very little effect at all.
So, keep an eye on Solarham.com for real-time updates and look for increased solar wind speed as the main indicator of the approaching solar material.
If the Bz does point south we may expect unsettled conditions and possible aurora today, the 2nd.
Meanwhile, three sunspot groups are rotating into an Earth-facing position in the Northern Hemisphere on the Eastern side of the Sun. We have already seen an M-class flare from one of them.
These could boost the solar flux index but could also be a source of solar flares and coronal mass ejections over the coming week.
Strangely, NOAA does not seem to think they will, as its predicted solar flux index over the next seven days is in the 150 to 160s range. It does agree with our prediction of unsettled geomagnetic conditions, although with a projected Kp index of 5 today, the 2nd, falling to 4 over the next three days.
We will just have to wait and see.
Meanwhile, maximum useable frequencies over a 3,000km path are still exceeding 28MHz from around 0830 to 1600 UTC. As the month moves on, we can expect the amount of daylight to increase, so this period may be extended.
Make the most of 160 and 80m as the optimum time for these bands has now passed.
And now the VHF and up propagation news from G3YLA and G4BAO
The tail end of the previous week saw a few weak weather features as lows and a front brushed past. However, from this first weekend of February, there will be a trend to higher pressure, which will offer up some tropo opportunities at times during the coming week.
There is a chance of the occasional decaying front drifting down the country but, for most of the next week, it’ll be a tropo story, if anything.
50MHz has been quiet again as we await the return of maybe the last Spring equinox-style propagation of this cycle around mid-March.
Meteor scatter is once again mostly down to random activity although there is one minor shower, the Capricornids-Sagittariids, which peaked yesterday, Saturday the 1st of February.
Rain scatter may be somewhat rarer due to the mainly high-pressure pattern.
Some auroral propagation is not without hope in view of the large coronal hole, which crossed the Sun last week. Keep a lookout for high Kp values, and keep an ear open for watery signals on the LF bands as a good sign of potential activity on the higher bands.
Moon declination goes positive again today, the 2nd. With perigee having passed late yesterday, the 1st, this means that the upcoming week will be good for EME. This is especially true on the GHz bands if you have a clear view of the horizon. 144MHz sky noise is low, rising to moderate next weekend.
One final note: there have been some access problems with the data feeds for the Propquest website. Hopefully, these are temporary and have fixed themselves by the time you hear this broadcast. The other data plots such as jet stream charts should continue to update so there is plenty to look at on the other pages.
And that’s all from the propagation team this week.

The news headlines:
The RSGB has announced the details of the amateur radio activity that it provided for the British Science Week 2025 Community PackNominations encouraged for the role of RSGB PresidentThe next Tonight@8 webinar will focus on fault finding in construction projects
The RSGB is delighted to announce details of the amateur radio activity that the Society provided for the British Science Week 2025 Community Pack. The RSGB Outreach Team, working with the RSGB Comms Team, submitted two activities on this year’s theme of ‘Change and adapt’ and one was chosen for the Community Pack. This activity was created by John Hislop, G7OHO and tested by RSGB School Youth Champion Chris Aitken, MM0WIC, and other members of the Outreach Team with various groups and ages. It uses amateur radio to find out if people in different countries are seeing changes in their weather patterns. It is a simple activity that is also designed to get people on the air. Community or youth groups will need access to a Digital Mobile Radio repeater and assistance from a radio amateur, which is why the RSGB is asking for the support of the amateur radio community to make this as effective as possible! You can find the RSGB activity and other resources on its website at rsgb.org/bsw so take a look and get ready to be involved! You can also find the full set of this year’s activity packs at britishscienceweek.org To ask questions or suggest an activity, contact the RSGB British Science Week Coordinator Ian Neal, M0KEO via [email protected].uk
The RSGB President is a prestigious and important role. Each President has the autonomy to shape the duties and activities they carry out to best match their view of the role. Former Presidents have spoken of the unique insight it has given them into the hobby, and the fulfilment they have felt from the role. Read more from the current and some previous Presidents by going to rsgb.org/president If you believe you can advocate for amateur radio, that you have the necessary understanding of how the RSGB works, and are someone who can relate to and talk engagingly with a wide range of people, then why not apply to be the next RSGB President? Nominations are now open in the RSGB 2025 elections and full candidate packs can be found via rsgb.org/election Applications are strongly encouraged from radio amateurs of all different backgrounds and identities.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 23rd of January 2025
This week, ending today the 26th, has looked a lot like a repeat performance of two weeks ago. The majority of the sunspots are in the western hemisphere with very few in the eastern side. This means that the solar flux index could drop over the coming week unless there are sunspots ready to rotate into view to replace those being lost.
A look at the STEREO Ahead spacecraft imagery suggests that there are indeed sunspots over the Eastern limb, so all may not be lost.
Overall, the Sun has been fairly quiet. There were no X-class flares and only five M-class flares from the 19th to the 23rd of January. The Kp index has also been relatively low, only peaking at four for one three-hour period on the 20th of January.
As a result, with the solar flux index in the 200s, HF conditions have been quite good. The maximum usable frequency over a 3,000km path has been consistently over 28MHz, from around 0830 to 1600 UTC. However, the 20, 17, 15 and 12m bands, seem to be carrying most of the DX at the moment.
Next week, NOAA predicts that the solar flux index will remain in the mid-200s. Geomagnetic conditions are also predicted to be good until the end of the month, but a Kp index of 5 is forecast for the 31st of January, and this could last for a few days.
So, we urge you to make the most of the conditions now, before geomagnetic storming, if it occurs, makes a mess of HF as we enter February.
And now the VHF and up propagation news from G3YLA and G4BAO
The weather pattern is being driven by a very strong winter jet stream across the Atlantic Ocean. This gives scope for rapid development of deep lows and consequent gales and damaging winds.
On Friday the 24th of January, the first big storm hit the northwest of Britain. We may find that the next low in the series is heading for southern Britain tomorrow, the 27th.
This all makes tropo unlikely for much of the week ahead since it stays unsettled through most of the period but with the smallest hint of higher pressure trying to return from Thursday.
Rain scatter will probably be worth some consideration on the GHz bands while meteor scatter remains driven by random activity rather than any major showers.
There have been further aurora alerts over the last week and it's always worth keeping the Kp index in view to monitor any possible chances for aurora. High figures, above a Kp index of 4, are a good trigger point to get interested.
Moon declination reaches a minimum in the northern hemisphere today, the 26th, when Moon windows are at their shortest and peak Moon elevation is at its lowest.
Path losses are now falling as we passed apogee on Tuesday the 21st. 144MHz sky noise is high, reaching over 3,000 Kelvin today, the 26th, before dropping to moderate until Wednesday when the Moon and Sun are very close in the sky for the whole Moon pass. After this, it drops to a low for the rest 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 16th of January 2025.
It looks like the lull in sunspot activity is coming to an end as the solar flux index rose to 174 on Thursday the 16th, after a week in the 150s and 160s.
The Sun was fairly bare, but there are now signs of more sunspot activity rotating into view.
There have been no X-class flares in the past seven days and only one M-class event. This has meant that the Kp index has been low, thanks to a lack of associated coronal mass ejections. There were four during one three-hour period on the 13th of January.
As a result, HF conditions have not been too bad with daytime maximum useable frequencies, or MUFs for short, over 3,000km regularly exceeding 24 and even 28MHz at times. However, nighttime MUFs are still in the doldrums, often struggling to get above 5MHz over a 3,000km path. This will no doubt change as we head towards spring.
DX on the bands recently has included S01WS in Western Sahara and UP7WWA in Kazakhstan, both on 28MHz CW. Closer to home we have had GB200LB celebrating the bicentenary of the invention of the Braille code and GB1GKA commemorating the 100th anniversary of the Portishead Radio receiving station, callsign GKA, at Highbridge, Somerset. Both of these stations were active on the 20, 17, 15 and 10m bands using CW.
At the other end of the bands, Kev, VK6LW, has been heard on 1822kHz from Western Australia at his sunrise at 2112UTC, as has Robert, DU7ET, in the Philippines at 2200UTC. January is a great month for top-band contacts.
Next week, NOAA predicts that the solar flux index will remain in the 160 to 175 range. Geomagnetic conditions are predicted to be good with a maximum Kp index of 3.
Watch solarham.com for news of solar flares and coronal mass ejections, which could easily send the Kp index higher and the MUFs lower.
And now the VHF and up propagation news from G3YLA and G4BAO.
The current spell of high pressure has served us well with some good tropo paths around the edge of the high into Spain and Portugal and even beyond to Madeira.
This has shown how effective long maritime ducts can be around the edge of areas of high pressure.
On the 16th of January, the Atlantic was taking over the agenda and low pressure near Scotland was pushing a weakening front into north-western Britain as the high retreated east into Europe.
The rest of the coming week has other lows bringing some rain or showers – especially to the north-west of the UK where it will become quite windy again. On Wednesday the 15th, weather models suggested a small high may return to the southern part of the country.
We are in a rather unsettled weather period with some limited rain scatter potential for the GHz bands. Meteor scatter is also a bit thin with just a possibility of scatter via the Gamma Ursae Minorids, which peaked yesterday, the 18th. However, the number of meteors is at a very low rate and so is not a great option.
Next, we move on to aurora and there continue to be examples of alerts suggesting minor events. Generally, though, spring is usually a better time, so there's still a while to wait.
Saturday the 11th of January brought a welcome out-of-season Sporadic-E opening to Poland, and then the Balkans, on 50MHz lasting around three and a half hours from 1200UTC.
Another good piece of news is the return of ionosonde data for the propquest.co.uk website after a few missing days. This is a timely opportunity to thank all those who maintain the professional data sets that allow us amateurs to see what the bands are doing.
Moon declination is positive, going negative this Sunday. Moon windows will shorten, and peak Moon elevations fall. Path losses continue to increase as we approach apogee on Tuesday. 144MHz sky noise is low all week.
And that’s all from the propagation team.

GB2RS News
Sunday the 12th of January
The news headlines:
There are opportunities in the RSGB’s Regional TeamWorld Thinking Day on the Air is coming up in FebruaryAre you interested in an exciting opportunity to volunteer with the amateur radio maker community?
If you’re looking to get involved in a different side of amateur radio this year, have you thought about becoming a volunteer RSGB Regional Representative for your area? There are eight Regional Representative posts available for nomination in this year’s RSGB elections. This rewarding role will give you the opportunity to represent the views of members in your region to the Board, as well as supporting and advising the District Representatives located within the Region. Regional Representatives are also members of the volunteer Leadership Team and have the opportunity to contribute to the Society’s strategy and policy development, as well as to its implementation. If you think this sounds exciting, and you are a confident communicator who has experience in managing people, then go to rsgb.org/election and read the candidate pack now. You’ll also find details about how to apply, alongside information on other roles, including the RSGB President and two Elected Board Director vacancies. The closing date for all vacancies is 2359UTC on the 31st of January. So, act now and use your expertise to make an impact on amateur radio in your region.
On the 15th of February, Girlguiding members will celebrate World Thinking Day on the Air. The aim of this event is to encourage Girlguiding members to make friendships with those in other units, using amateur radio as the means of communication. On this day, Crawley Amateur Radio Club and RSGB volunteers will be hosting a special event call sign GB1SCG, which relates to Sussex Central Guides. Girlguiding members of all ages will have the opportunity to celebrate by communicating via the amateur bands. If you or your amateur radio club are planning to work with a local Girlguiding group for World Thinking Day on the Air, please get in touch via [email protected].uk so the RSGB can promote your event.
As part of the RSGB’s ongoing strategy to take amateur radio to new and diverse audiences, it is delighted to advertise a new volunteer role. This is an opportunity for someone to be an advocate for amateur radio within the maker community. The spirit of experimentation, curiosity and learning is common to both groups and the RSGB would like to foster greater crossover between the amateur radio and modern maker communities. This crossover would be centred around hackspace and maker spaces, as well as larger events, but would also encourage individuals from each community to inspire and learn from each other. This role is intended to help take amateur radio to a new audience with an emphasis on how the licence would support other hobbies, rather than the promotion of traditional amateur radio activities. To carry out this role you’ll need to be open to working with different communities, be proactive and organised, and be able to build a team and help it to work to achieve goals. To find full details of the role go to rsgb.org/volunteers and if you’re interested in applying or being part of a wider team, contact RSGB Board Director Mark Jones, G0MGX via [email protected].uk
The RSGB is recruiting volunteers for two roles that are fundamental to the delivery of the Society’s Convention. The Convention Chair will be someone who understands the advantages of both online and in-person events. The successful applicant will have an awareness of all aspects of amateur radio and will contribute to shaping the RSGB Conventions of the future to suit the changing amateur radio audience. A second opportunity to be part of the Convention team is as the Society’s Lecture Coordinator. This role is part of both the Convention and Tonight@8 teams and requires someone who is proactive and collaborative. The applicant will need to bring ideas for presentations that educate and inspire radio amateurs to try something new, learn more about interesting topics and expand their knowledge of amateur radio. To find out more about either of these roles and how to apply, go to rsgb.org/volunteers
Don’t forget that the next event in the popular 145 Alive series will take place on Sunday the 26th of January 2025. It will run from 12 pm to 3 pm and there will be nets operating in most Maidenhead Squares across England, Scotland, Wales and Ireland. To take part in the event, which is designed to promote FM activity on the 2m band, all you need to do is call in and make contact with others. For more information visit the 145 Alive Facebook page.
Please send details of all your news and events to [email protected].uk The deadline for submissions is 10 am on Thursdays before the Sunday broadcast each week.

On Saturday the 18th, the RSGB Affiliated Societies 80 and 40m SSB Contest runs from 1300 to 1700UTC. Using SSB on the 80 and 40m bands, the exchange is signal report and serial number.
Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 9th of January 2025.
First, let’s take a look at last week’s solar activity. As predicted, the solar flux index declined to the 160s. We had one X-class solar flare on the 4th and there have been 11 M-class flares since then. The net result was that the ionosphere was unsettled from the 4th to the 6th of January with the Kp index hitting 5 on the 4th. Following this, the Kp index was at 4 on the 5th and 6th of January.
There were reports of visible aurora over the UK on Saturday the 4th, but it was nothing like the record-breaking aurora in April 2024.
There were coronal mass ejections, or CMEs, over this period but they were mainly facing away from Earth. Maximum usable frequencies, or MUFs for short, held up over this period, although the shorter days meant that the MUF over a 3,000km path didn’t stay above 28MHz for long after sunset. MUFs plummeted to below 10MHz by 1800UTC on Sunday the 5th.
The message is clear – get your high-band DXing done by sunset!
Next week it looks like the Sun is going into hibernation. The main sunspots will be disappearing over the western limb, leaving it looking a little bare. As a result, NOAA predicts that the solar flux index will remain low until the 16th when it is predicted to climb into the 200s once again.
Unsettled geomagnetic conditions are forecast from the 16th to the 20th of January with a predicted maximum Kp index of 4. There are currently no coronal holes to worry about.
So, in conclusion, this weekend ending the 12th looks set to be reasonable for HF operating, barring any X-class solar flares and accompanying CMEs. We predict that MUFs over 3,000km will be above 28MHz from around 0900UTC to 1500 UTC.
And now the VHF and up propagation news from G3YLA and G4BAO.
We are in the middle of a proper winter cold spell at the moment, and we are about to see a large high coming over the country.
This high is building in cold air and it means sharp frosts and perhaps some fog, so there’s a chance of patchy tropo at times. Conditions may further improve as the high slips south after this weekend ending today the 12th. This may allow milder, moister Atlantic air in from the west to improve the refractive index contrast across the inversion, which could lead to tropo.
The solar conditions have remained interesting and produced a few aurora alerts, so we can probably benefit from watching the Kp index during the coming week.
Meteor activity has passed its early January peaks, and we are now sliding back into random meteor activity as our best option. These tend to be better just before dawn. There is just one minor shower this week. The Gamma Ursae-Minorids are active from the 10th to the 22nd of January and peak on the 18th.
We have mentioned Sporadic-E quite a lot recently but, with the passing of the meteor activity, the chances of it occurring have reduced considerably. Although limited activity may enhance the lower bands, it probably won’t feature in the usual high HF and VHF bands.
The Moon reaches maximum declination this weekend, ending today the 12th. Moon windows are long and peak Moon elevations are high. Path losses are also high and increasing all week. 144MHz sky noise is low all week.
And that’s all from the propagation team.

What are your goals for 2025? Could you spare some time and share your expertise to make a difference within the amateur radio community? The RSGB 2025 elections process has begun, and nominations are open for a range of volunteer roles. The RSGB’s President John McCullagh, GI4BWM will reach the end of his second year as President at the AGM and so will stand down. There are also two Elected Board Director vacancies. The Board is looking for people with specific skills to fill these roles. The current President is one of the few at the Board level with extensive experience in spectrum matters and negotiating with the authorities – so that skills gap needs to be filled. Outreach has been an important focus over the last year for the Society and it would like to support the current activities and expand on them. These developments will include encouraging practical skills amongst the amateur radio community and also building links with other organisations. Building those relationships will require someone with drive and determination but also tact and diplomacy. There are eight further posts available for RSGB Regional Representatives, ranging from Region 1 in Scotland to Region 11 in the southwest. For more details about the roles as well as application forms and candidate packs, go to the RSGB website at rsgb.org/election

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 2nd of January 2025.
We started the new year with a bang, or more precisely a Kp index of 8 and widespread visible aurora. This was caused by a partial halo coronal mass ejection, associated with an eruption in the Sun’s southeast quadrant on the 29th of December.
The strong G3 to severe G4 geomagnetic storm peaked at about 1800UTC on the 1st of January as the solar wind speed moved past Earth at just above 500 kilometres per second. It then subsided as the Bz component settled into a north-pointing position.
HF propagation suffered as a result with the maximum usable frequency down for the rest of the evening. By the morning of the 2nd of January, things had improved and maximum usable frequencies over a 3,000km path were back above 28MHz.
The solar flux index remained above 200, which no doubt helped, but we are in rocky times from a space weather point of view.
A large coronal hole became Earth-facing on Friday the 3rd of January which will no doubt cause some geomagnetic disruption today, the 5th, as the Kp index rises.
NOAA predicts the solar flux index may decline this week, possibly ending in the 160s to 170s. Geomagnetic conditions may also be in for a rough ride around the 10th and 11th when the Kp index is forecast to reach 4.
From a radio point of view, January is a peak time for low-band DXing. The nights are long and dark so make the most of the 160 and 80m bands. You may also get DX during the late afternoon on the 40m band.
During the daytime keep an eye on the 10m band, which may throw up the odd, interesting DX station while the solar flux index remains high.
And now the VHF and up propagation news from G3YLA and G4BAO.
To start the year the main feature is low pressure over the country but, in the depths of winter, it's good to remember that snow and rain both provide scattering opportunities for the GHz bands.
There is a glimmer of tropo hope for the end of the coming week, around the 11th and 12th, as high pressure builds over northern Britain. This will be a cold-air high which tends not to be the best for tropo, but it's worth a look nonetheless.
The solar conditions provided an aurora on New Year’s Day with a brief index of 8 during the afternoon. With other disturbances possible, it is worth keeping up to date with solar conditions and prospects for geomagnetic storms on spaceweather.com This is one propagation mode where CW is so much easier to copy under the difficult conditions of aurora.
Meteor scatter propagation is driven by the Quadrantids in the first week of January. It peaks on the 4th but spans the period up to the 12th. This is a productive shower with an hourly rate of 120. Since it’s the last major excitement until the late April Lyrids, make the most of it before we’re reduced to chasing random meteor activity during the rest of winter.
We have previously mentioned the chance of out-of-season Sporadic-E propagation in mid-winter and we still have the next week to keep alert, especially in view of the Quadrantids adding fuel into the E region. The ionised trails of the meteors provide long-lived metallic ions, which is the material that gets focussed into Sporadic-E if we are lucky.
The Moon starts the weekend with a negative but rising declination, going positive today, the 5th, so Moon windows continue to lengthen. Path losses are low with perigee on Wednesday. 144MHz sky noise is low all week.
And that’s all from the propagation team this week.

The news headlines:
The RSGB is looking for a new Lecture CoordinatorYOTA Month draws to a close but is still busy on the airThe first RSGB Tonight@8 webinar of 2025 focuses on GB2RS
The RSGB facilitates just over 60 lectures each year in a mixture of in-person, hybrid and remote formats. 50 of these are at the RSGB Convention and 11 are delivered through the livestreamed Tonight@8 webinar programme of events. This set of presentations aims to cover a wide mix of amateur radio-related subjects, across all depths of amateur radio experience and knowledge. They are watched and admired by RSGB members and non-members across the world. The RSGB Lecture Coordinator is part of the Tonight@8 and Convention teams. Its recent Lecture Coordinator Keith Hotchkiss, G0FEA has stepped back to focus on his professional commitments, so the RSGB is looking for someone new for this volunteer role. The right person will be proactive and collaborative, bringing ideas for presentations that educate and inspire radio amateurs to try something new, learn more about interesting topics and expand their knowledge of amateur radio. They will lead the invitation and scheduling process for Tonight@8 webinars and contribute to the decisions about Convention presentations. They will also be the main contact with Convention presenters, inviting them to speak, updating the speaker project plan and helping to create a balanced programme. Reporting to the Convention Chair, the Lecture Coordinator would be a member of the RSGB Convention team but would not be required to take responsibility for organising and managing other aspects of the event. If you’re interested in the role or would like to find out more, please contact the RSGB General Manager Steve Thomas, M1ACB via [email protected].uk

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 19th of December 2024.
The last week was a little more disturbed than usual and we had a Kp index that hit 5.33. An enhanced solar wind stream contributed to active geomagnetic conditions and an interplanetary shockwave, that swept past Earth at 0519UTC on the 17th of December, caused minor G1 geomagnetic storming.
A far-sided halo coronal mass ejection event also occurred later on the 17th of December at 1600UTC although this was not directed towards Earth.
This shows that the Sun is still very active, and we should not be surprised if we experience more solar flares and CMEs.
The solar flux index stayed in the 160s and 170s and we should keep an eye on active region 3927, which is currently turning to be Earth-facing and has already been the source of some C-class solar flares.
Next week NOAA predicts that the solar flux index may rise slightly to be in the 180s. The largest Kp index forecast is 2, which probably means that NOAA is unsure about what will actually happen.
We are pleased to report that OF9X is once again on the air from the land of Santa Claus in Lapland. Up to 16 operators will operate Santa Radio on the 160 to 6m bands using CW, SSB, RTTY, FT4 and FT8. They have already been spotted on the 30 and 20m bands using CW and on the 12 and 17m bands using RTTY. So, there is plenty of scope to work them.
According to the prediction program Proppy, paths to Lapland should be open on 14MHz from 0800UTC to 1800UTC. On 28MHz, expect them to be open from 0930 to 1500UTC. The 80 and 40m bands should be mainly open during the hours of darkness.
As always, across the Christmas period, we recommend that you use solarham.com and propquest.co.uk for real-time updates on solar and ionospheric conditions.
And now the VHF and up propagation news from G3YLA and G4BAO.
Last week ended in a colder unsettled period of weather with strong north-westerly winds and spells of rain or showers.
The air is sufficiently cold that some snow is possible over northern hills. This is potentially good news for rain or snow scatter, especially off fast-moving showers down the coastal fringes of the UK.
Although the nearest high remains near the Azores to begin with, it slowly migrates east to France and, by Christmas, to central Europe. This will bring high pressure and possibly Tropo onto Santa’s list from Christmas Eve onwards. Look for patches of misty low cloud or fog for the best conditions.
As usual, check for other modes. Meteor scatter and aurora are both worth consideration and this is a prime time for out-of-season Sporadic-E between now and about mid-January.
One of the helpful aspects of looking for winter Sporadic-E is that quite often the jet streams are significantly stronger than in the more traditional summer Sporadic-E season. Jet streams are a good source of turbulence that can eventually propagate up to the E region to make Sporadic-E propagation.
Jet streams are shown on upper air charts and can be a good geographical guide to Sporadic-E prospects in the summer and should therefore be similarly consulted for these winter events.
In this case, they tell us that the first half of the coming week, up to Christmas Day, is well set up with a northerly jet stream over central Europe and, more importantly, crossing the Alps. So, a second mode goes on to Santa’s list.
Check the VHF Cluster’s Sporadic-E graphs at propquest.co.uk for early signs of activity, particularly for paths to the southeast into Italy and the Balkans.
The Moon started this weekend with positive declination but goes negative late today, the 22nd. Path losses are at their highest due to apogee on Christmas Eve. 144MHz sky noise is high until Wednesday, including near-eclipse conditions all day on Monday.
That’s it for this year. How about making a New Year’s resolution to try a new mode? Maybe use SSB or CW on VHF now and again and put out lots of CQ calls in 2025!
And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 15th December 2024
13 dec 2024· GB2RS
GB2RS News
Sunday the 15th of December
The news headlines:
The RSGB 2025 election nominations process is openThe Society is advertising for a new Convention ChairYOTA Month is busy this week with more callsign hosts to listen out for
The RSGB 2025 elections process has begun, and nominations are open for a range of volunteer roles. The RSGB’s President John McCullagh, GI4BWM will reach the end of his second year as President at the AGM and so will stand down. There are also two Elected Board Director vacancies. The Board is looking for people with specific skills to fill these roles. The current President is one of the few at the Board level with extensive experience in spectrum matters and negotiating with the authorities, so that skills gap needs to be filled. Outreach has been an important focus over the last year for the Society, and it would like to support the current activities and expand on them. These developments will include encouraging practical skills amongst the amateur radio community and building links with other organisations. Building those relationships will require someone with drive and determination but also tact and diplomacy. There are eight posts available for RSGB Regional Representatives, ranging from Region 1 in Scotland to Region 11 in the southwest. For more details about the roles as well as application forms and candidate packs, go to the RSGB website at rsgb.org/election
The RSGB has been developing its Convention over recent years to suit the changing needs of the amateur radio community. From a face-to-face meeting, it evolved into an online event when we weren’t allowed to meet, then changed again into a hybrid event, bringing together the best of both for people in this country and across the world. The Society has also been developing the programme to include practical workshops and forums to support radio amateurs who would like a safe and accessible environment in which to try to develop their practical skills. The RSGB General Manager has been doing the role of Convention Chair for the last three years but has now stepped back from that additional voluntary role, so the RSGB is looking for a new Convention Chair. This role needs someone who understands the advantages of both online and in-person events and who can contribute to shaping the RSGB Conventions of the future to suit the changing amateur radio audience. The RSGB is looking for someone enthusiastic, proactive, collaborative and good at working with others in a strong team. They will also need an awareness of all aspects of amateur radio, including the latest developments and what might be on the horizon. As part of the wider Convention team, they will need to suggest ideas for speakers and practical activities that will attract a range of radio amateurs. If you believe you could contribute to the development of this prestigious annual event, the RSGB would like to hear from you. Please contact the RSGB General Manager Steve Thomas, M1ACB via [email protected].uk
Youngsters on the Air Month is now halfway through, with plenty more operators booked to host GB24YOTA. There is still time to work the RSGB National Radio Centre’s GB3RS station which is hosting the callsign for the duration of today, Sunday the 15th of December. On Wednesday, the 18th of December, the Simon Langton Boys School in Canterbury will be operating between 12 pm and 6 pm. On Thursday, the 19th of December, between 12 pm and 6 pm the Cambridge University Wireless Society will once again be hosting GB24YOTA. To finish up this week, Tommy, M7OMY will be operating on the 20th and 21st of December under the supervision of Las, M0BOY. Tommy is a young radio amateur and has been taking part in YOTA Month for a few years, so be sure to listen out and make a QSO with him. Search GB24YOTA on QRZ.com to view the full operating schedule.
The RSGB’s headquarters will close for the Christmas and New Year period from 2pm on Tuesday the 24th of December 2024. It will open again at 8.30am on Thursday the 2nd of January 2025. During that time, if you need information about amateur radio, exams or RadCom, you’ll find lots of information on the website via rsgb.org If you are planning to visit the RSGB’s National Radio Centre at Bletchley Park over the holidays, please note that it will be closed on Christmas Eve, Christmas Day, Boxing Day and New Year’s Day. On New Year’s Eve, the NRC will close at 2 pm. The National Radio Centre will also be closed for essential maintenance works on Thursday the 2nd of January 2025. 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 via rsgb.org/bpvoucher
On the 6th of December, Ofcom announced an update regarding the timing of phases two and three of its amateur radio licensing framework, including changes to the new intermediate call signs and rules for Special event Stations. These phases were originally planned for December 2024 and March 2025 respectively, but Ofcom now expects to deliver them in the third quarter of 2025.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 12th of December 2024.
We had another week with quiet geomagnetic conditions. Other than three hours with a Kp of four on the 9th of December, as of last Thursday when this report was being compiled it had been below three for the past seven days.
Active region 3920 produced an impulsive M2.8 solar flare, peaking at 1006UTC on the 11th of December. A quick M2.0 flare was also detected around AR3922 in the southeast quadrant. There was also an M6.4 solar flare at 0648UTC on the 10th of December, but no Earth-directed coronal mass ejections were observed.
The solar flux index, despite being predicted to reach 200 again, has been simmering away in the 160s and 170s. Nevertheless, the quieter geomagnetic conditions have helped HF with the extrapolated MUF over a 3,000km path often hitting 40MHz at times.
However, the early sunset, which is around 1538UTC to 1621UTC at the moment depending on your location in the UK, means that the MUF drops off quite quickly in the afternoon. The average critical frequency at night is currently about 3.0-3.5MHz, which explains why the HF bands appear to be dead. The winter solstice is on the 21st of December, and we won’t see much change until we get to mid-January.
There is DX to be had with CDXC members reporting working YJ0CA (Vanuatu) on 15 metres, V73WE (Marshall Islands) on 30 metres and YI1QEA (Iraq) on 10 metres.
So, at the moment, make the most of the daytime DX and greyline openings, and reserve the evening for Top Band and perhaps 80 metres.
Next week, NOAA predicts that the solar flux index will remain around 170 to 175. The Kp index is expected to be around two or three, apart from the 19th of December when it could reach four.
And now the VHF and up propagation news from G3YLA and G4BAO.
The period of enhanced Tropo activity will have faded away by this weekend as the high pressure slips away into Europe and declines. This allowed low pressure to regain control from last Friday through the current weekend.
There may be a chance of some rain scatter propagation on the GHz bands, although it doesn’t look like a particularly good example.
All is not lost for Tropo followers, since the next high drifts in from the Atlantic early next week. The southern UK will benefit the most with Tropo paths to France and across Biscay. This lasts until midweek, to be followed by a return of low pressure for the second half of the week and probably a better rain scatter option than this weekend.
The big Geminids meteor shower peaked yesterday, the 14th of December, but will linger throughout the month. The radiant source rises late afternoon and sets the following lunchtime and is most favourably positioned late evening and early morning, pre-dawn.
Next, a consideration of aurora prospects, which are still a little enhanced by solar conditions. So, as usual, stay alert to an increasing Kp index above Kp=4 to keep in the game.
Finally, remember that the period of Christmas and early January is well known for producing random out-of-season Sporadic-E. It's not possible to fine-tune Es prospects this far ahead, but it wouldn’t hurt to monitor the f0Es traces on the www.propquest.co.uk website between now and mid-January.
The Moon’s declination is at maximum today, Sunday the 15th of December, and also on Monday, so expect long Moon windows with high peak elevations. Path losses are still low but rising, so it’s still a good week for EME. The 144MHz sky noise is moderate to low all 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 5th of December 2024.
We had another week of high solar activity but limited geomagnetic disturbances. This meant that the upper HF bands were playing ball all week.
The Kp index only exceeded four on one occasion, on the 30th of November when it hit 4.67, but otherwise, it has been low.
With a solar flux index mainly in the 180s, this allowed the upper HF bands to shine. The maximum usable frequency or MUF over a 3,000km path has been consistently over 35MHz during daylight hours.
The MUF over 100km has also been more than 14MHz around midday, making 20 metres almost a local band at times thanks to near vertical incidence skywave signals! If you have worked anyone in the UK on 20 metres let us know.
An approaching active region just off the east limb of the sun was responsible for an M2.3 solar flare on the 4th of December, so perhaps increased solar activity is on the horizon.
Next week NOAA predicts the week will start with the solar flux index starting in the 180s, perhaps then increasing to 200 as the week progresses.
An increased geomagnetic disturbance is forecast for the period of the 10th to the 13th of December when the Kp index could increase to four.
If this does come to fruition, we can expect MUFs to drop until the storming has passed. As always keep an eye on Propquest.co.uk for near-real-time MUF figures and solarham.com for Kp indices.
And now the VHF and up propagation news from G3YLA and G4BAO.
Meteor scatter is top of the list this coming week, with the big Geminids shower lasting throughout the month and peaking on Thursday the 14th of December.
With a peak zenith hourly rate (ZHR) of 150 it's one of the most active and reliable of the annual showers. Other lesser meteor streams are also in play, so check the meteor scatter frequencies on 144, 50 and 70MHz where digimodes MSK144 and FSK441 will dominate activity.
We have another period of primarily unsettled weather for the lead into this weekend, with deep lows bringing heavy rain, and perhaps some snow over northern hills.
Watch out for very strong winds with potentially damaging gales in places. By the time many of you hear this on Sunday the 8th of December, we will be mid-way through the main event but hopefully, your antennas have survived.
The better news is that the first half of the week is dominated by high pressure, so this brings a chance to repair antennas and get some Tropo time before a slow drift back to unsettled conditions in the second half of the week.
For other modes, GigaHertz band rain and snow scatter will be worth considering especially over the weekend and again later in the week.
Last Friday afternoon saw another big 50MHz F2 opening to North America, so continue to be vigilant if you’re in the shack after lunch and the Kp index is below two.
The solar conditions mean that there is still a chance of Aurora, although the Sun has been a bit quieter recently. Some days the f0Es trace on Propquest shows that weak Sporadic-E is still occurring.
The Moon’s declination is rising again and going positive on Monday. With falling path losses as we approach perigee on Thursday, it’s a good week for EME. 144MHz sky noise is low all 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 28th of November 2024.
Last weekend’s CQWW CW contest was a reminder of just how good HF propagation can be near sunspot maximum.
The whole world was workable on the contest bands up to 10 metres, including the Far East, Australasia, the Caribbean and South America. It was a great opportunity to increase your DXCC total and have fun at the same time.
This week’s solar flux index crept back above 200 again, peaking at 225 as this report was being prepared. Geomagnetic conditions have been surprisingly good over the past seven days with a peak Kp index of 3.67 on the 24th of November.
There have been no X-class solar flares, but there has been a total of 13 M-class and 54 minor C-class flares over the past seven days. There have been coronal mass ejections, notably on the 25th of November, but they have not been Earth-directed as of the 28th.
So, to summarise, HF conditions have been pretty good.
We are now entering the Winter period for HF propagation, which tends to favour the low bands. So 160m, 80m and 40m come into their own and night-time DXing becomes the norm. Look for greyline openings to the west at sunrise on 80m and 160m, and also short, but good, openings on 40m in the late afternoon.
Nighttime may bring good DX on 80m and 40m, including the Caribbean and South America.
NOAA predicts that the SFI will remain in the low 200s next week, and while geomagnetic conditions are forecast to be good at first, the Kp index may rise to four on the 4th to 6th of December. This could result in reduced MUFs until the Kp index recovers.
And now the VHF and up propagation news from G3YLA and G4BAO
The unsettled theme continues through most of the next week or two. The only signs of slightly enhanced prospects for Tropo are as we close this week, and even that is restricted to some eastern areas for paths across the North Sea.
A second option may temporarily appear around the middle of the coming week as a weak high crosses southern areas, but this one looks to be a cold high and probably not so good as a vehicle for Tropo.
The meteor scatter prospects are aided by the last throes of the Leonids which fade away by this weekend, and the Orionids which peaked on Thursday the 28th of November, but last through the coming week.
The unsettled weather should offer some useful GHz bands rain or snow scatter, since there will be several active weather systems around. This early in the winter is a great time for strong shower activity around the still relatively warmer seas.
The auroral prospects are worth checking after recent activity. Look for watery-sounding signals on the LF bands as a good clue along with Kp index values greater than four.
Last week saw some fleeting signs of Sporadic E on the Dourbes ionosonde graphs on propquest.co.uk, especially on Monday the 25th of November. This occurred typically around the middle of the day and was probably driven by the very strong jet stream and the current meteor activity.
The Moon’s declination is negative, reaching minus 28 degrees on Monday and we are close to eclipse on Sunday. That’s followed by two days of high 144MHz sky noise, so with path losses still high, EME operators should probably take the opportunity to check their antennas after last week’s gale.
And that’s all from the propagation team this week.
