Apply to become the RSGBâs new CW ChampionThe Tonight@8 series continues in June with Morse codeCould you be the RSGBâs new STEM Champion?As part of the RSGBâs ongoing strategy to take amateur radio to new and diverse audiences, it is seeking to appoint a volunteer CW Champion. Whilst the need for a CW test has been removed from the licensing requirements, there is still a strong interest in the mode. Recent communications and activity involving Morse have received high levels of interest, and the Society would like to do all it can to encourage and promote CW within the hobby. This new role will take the lead with activities including managing RSGB web content relating to Morse code and contributing to the GB2CW broadcasts. The volunteer will also be tasked with building a team of enthusiastic individuals who can support CW-related activities undertaken by the Society. This role is intended to help take Morse to new audiences with an emphasis on learning and development to further the skills of RSGB members. Read the full role description, as well as details of how to apply, by going to rsgb.org/volunteers
The next webinar in the Tonight@8 series is on Monday, the 2nd of June. The RSGBâs Morse Test Coordinator, Eric Arkinstall, M0KZB, will lead the webinar and will be joined by a panel of Morse experts, including RSGB Morse Assessor and GB2CW broadcaster Michael Topple, GM5AUG. The presentation will include an introduction to Morse, how to start learning the code, the different types of Morse keys and the Achilles heels that can occur when learning Morse. There will also be a panel discussion on how they each became interested in the mode and how they overcame any problems they have encountered along the way. Find out more about this and future webinars on the RSGB website at rsgb.org/webinars
Would you like to become the RSGB STEM Champion? This new volunteer role is part of the Societyâs strategic plans to encourage more young people into STEM careers and to demonstrate the contribution that amateur radio can make to those careers. The focus of the role will also be to develop and strengthen the Societyâs relationship with the STEM Learning organisation. The Champion will need to work closely with licensed STEM Ambassadors, attend STEM events to promote amateur radio, and support radio amateurs who would like to become STEM Ambassadors. The STEM Champion will work closely with the Board Liaison, Ben Lloyd, GW4BML and members of the RSGB Outreach team. To make the most of the role, you will need to have the right skills and experience. This includes being a STEM Ambassador with involvement in the STEM sector, and also being proactive, enthusiastic, organised and willing to find new ways to achieve the roleâs objectives. For full details of this challenging but rewarding role and how to apply, see the RSGB website at rsgb.org/volunteers

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 22nd of May 2025
A high-speed solar wind, originating from a massive coronal hole, took its toll on HF this past week.
During the weekend of the 17th and 18th, the Kp index was above four for nine of the three-hourly recording periods. Unfortunately, the feed from the Dourbes Digisonde failed over this period, so we canât comment on what effect this had on maximum usable frequencies, or MUFs for short.
Later in the week, geomagnetic conditions improved, despite the coronal hole still being Earth-centric, and the Kp index fell to more reasonable levels, sometimes in the ones and twos.
An M3.2 solar flare was observed at 08:21 UTC on the 19th of May. The source was located off the northeast limb, so perhaps we can expect more as it turns to become more Earth-facing.
Unfortunately, the solar flux index also fell to lower levels, reaching 119 by Thursday, the 22nd. In fact, on that day, it had been below 120 for more than seven days. But all is not lost, as a solar flux of more than 100 is usually enough to keep the HF bands open.
MUFs over a 3,000km path have generally reached 21 MHz and have often peaked at 24 MHz at times. It is quite normal for the F2-layer MUF not to reach 28MHz due to a change in the ionospheric chemical make-up in the summer â the so-called summer doldrums. However, Sporadic-E may keep 10m alive, so donât write the band off.
Propagation, at the moment, favours paths into the southern hemisphere, although each band can have different characteristics at different times. A quick play with the propagation tool at tinyurl.com/propcharts will show you what we mean.
Next week, NOAA predicts that the solar flux index will remain around 120 until the 27th of May, after which it could rise to 140 by the end of the month. Unsettled geomagnetic conditions are forecast for the period from the 28th of May to the 2nd of June. This could see the Kp index peak at five or six with corresponding drops in the MUF and DX.
As we are now on the downward portion of this solar cycle, we may expect more geomagnetic disturbances from coronal holes and coronal mass ejections.
And now the VHF and up propagation news from G3YLA and G4BAO
The long run of fine settled weather seems to have drawn to a close.
We have a period of changeable and, at times, wet and windy weather to deal with over the coming week. I doubt we will see much, if any, Tropo except perhaps towards the end of the week as some models show a new high building as we move into June.
Before then, the various fronts and showers will bring several spells of rain and a much greater chance of rain scatter on the GHz bands than recently.
The solar conditions have again provided weak auroral events, with fluttery signals on the HF bands being a good indicator, since the bright evenings and early dawns leave little chance of any visual clues. As usual, the measure to follow is the Kp index. So, look out for values of Kp going above five to generate interest.
Meteor scatter is declining as the last of the Eta Aquariids play out, following a long tail from the peak on the 6th of May. Meteors also make up the content of Sporadic-E because, as they burn up, they produce long-lived metallic ions that can be focused into thin layers of Sporadic-E.
There are some less well-known meteor showers in June. So, next week there may be more to say. In the meantime, random meteors and declining Aquariids will have to suffice.
Now, on to Sporadic-E. This is beginning to be the primary mode in these summer weeks. It is sensible to check during main operating windows in the morning, late afternoon and early evening.
Ideally, we require meteor input, a low Kp index, plus some weather triggers to set up atmospheric gravity waves which produce the right wind shear in the E region. Jet streams are usually the best clues for where Sporadic-E might form.
Use the daily Sporadic-E blog on the Propquest website to get an insight of the current dayâs weather patterns â see propquest.co.uk
If you have very limited time and have still not worked Sporadic-E, just checking 50MHz in the late afternoon will ensure that you make a start this year.
EME path losses are still falling as the Moon reaches perigee, its closest point to Earth, on the 26th of May. Moon windows and peak elevation are again rising, reaching a maximum on the 29th of May. 144MHz sky noise is low and remains low as the week progresses.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 15th of May 2025
This week, you could be forgiven for thinking that the Solar Cycle 25 maximum is now over. With a reduced solar flux index and an almost blank Sun, there was little to get excited about.
By Thursday, the 15th of May, the SFI was 122, but previously, on the 12th, it had been down to 116, which is the lowest it has been for some time. There is still a lot of solar activity going on, but most of it is not conducive to good HF propagation.
Over the past week, we have had two X-class solar flares and five M-class events. The X-class events were associated with coronal mass ejections, but these appear to have been directed away from Earth. A fast solar wind has resulted in the Kp index standing at four for a lot of the time, namely on the 9th and 10th of May and again on the 14th and 15th.
Unfortunately, this is not uncommon at this point in the solar cycle and adds some evidence that we are now in the declining phase of Cycle 25.
Next week, NOAA predicts that things may improve with the SFI set to rise from the 19th of May. It forecasts the SFI will start the week around 115, but then will climb steadily, reaching 145 by the 1st of June. After a brief rise on the 19th with a Kp of four, things then become more settled with a Kp of two between the 22nd and the 28th of May.
A large elongated coronal hole became Earth-facing on 16th May, which could cause raised K indices and lower MUFs from today, the 18th of May, onwards.
It looks like the best HF F2-layer conditions may occur between the 22nd and 28th of May.
And donât forget, despite the HF doldrums, we are now well into Sporadic-E season with short-skip occurring, predominantly on 10m. But more of that shortly.
And now the VHF and up propagation news from G3YLA and G4BAO
The prolonged spell of high pressure is likely to remain until near the end of this week, so there is plenty of time to get some more Tropo in the log.
Cloudier and cooler air over eastern Britain at the end of last week may enhance the Tropo by adding moisture under the inversion. For most places, the strongest Tropo conditions will be overnight and early morning, then they will degrade as the daytime heating destroys the surface temperature inversion.
Meteor scatter is declining a little, apart from a few stragglers from early May showers, so it's probably better to keep to the early morning period as your go-to time for meteor scatter to focus on any random input.
Rain scatter is unlikely until next weekend, but it might be worth thinking about the GHz bands from this Friday, the 23rd of May, onwards.
Aurora is a different matter, and the solar activity is likely to keep things interesting as a large sunspot group rotates into an Earth-facing position.
Strong Es opened on Wednesday, the 14th of May, so it's definitely the season to be checking the upper HF and lower VHF bands for Sporadic-E. In this recent opening, the Dourbes ionosonde peaked at an Es critical frequency of 14 MHz, which is a very high value, even for mid-season.
There were strong signals from the central Mediterranean on 6m CW, and some may have even got some 2m digital mode action from the brief opening. Check the Propquest NVIS tab for the day to see the details of this event.
Although weak jet streams were present, the opening may well have been helped by some very intense, slow-moving thunderstorms over France. Remember to start checking on 10m and, if itâs open, look to the higher bands of 6m, 4m, up to 2m.
EME path losses are still falling. Moon declination ended last week at minimum but goes positive again this Thursday, the 22nd of May. Moon windows and peak elevation are again rising. 144MHz sky noise is high this weekend, falling back to low as the week progresses.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 8th of May 2025
Active region 4079 turned out to be not quite so bad as we had predicted. The sunspot was large, about ten times the width of our Earth, so we expected it to be more active. It was regions 4081 and 4082 that produced most of the flare activity last week.
Two filament eruptions also occurred within two hours of each other. The first event began at 16:20 UTC on the 6th of May in the southern hemisphere and was responsible for a plasma wave across the surface of the Sun.
The second filament eruption began in the northern hemisphere around 17:50 UTC to the northeast of AR 4079. A large amount of plasma was flung to the north. The filament eruptions on Tuesday, the 6th of May, did produce coronal mass ejections, but an Earth-directed component was not apparent. So we dodged a bullet!
The solar wind speed remained high for most of last week which didnât help propagation. It did help to push the Kp index to five across the weekend of the 3rd and 4th of May. Things were more settled later in the week. On Thursday, the 8th of May, the solar wind speed was down to around 500 kilometres per second, the Kp index was three, but MUFs over a 3,000km path were still down at about 20 MHz.
An Earth-facing coronal hole may add to the solar wind this weekend, the 10th and 11th of May. It looks like summer HF propagation is kicking in, with lower MUFs during the day but higher ones at night.
Next week, NOAA predicts that the SFI will be in the range 155 to 165. Settled geomagnetic conditions are forecast for the beginning of this coming week, but unsettled geomagnetic conditions are expected for the 16th to the 19th of May. At that point, we could see the Kp index rise to five again, coupled with poorer propagation and reduced MUFs.
And now the VHF and up propagation news from G3YLA and G4BAO
Tropo has been a key propagation mode during the previous couple of weeks, but there have been variations in the location and timings of these conditions.
Sometimes this will be due to increased moisture below the temperature inversion, so although the cloudier areas have been cool, they have probably done better for Tropo.
This is due to the improved quality of the inversion, which performs better when there is a big moisture contrast across it, as you find with these layers of cloud.
Otherwise, we find that the better conditions are driven by night-time cooling, forming a low inversion near the ground which tends to disperse during the morning as the Sun warms it away. This should still be beneficial for the 70cm UK Activity Contest on Tuesday, the 13th of May, over eastern areas, but perhaps less so farther west.
Good conditions will last into next week, but not everywhere. The main change will see an area of showery rain, possibly thundery, moving north into western Britain this weekend and perhaps some central areas early next week. This raises the prospect of some GHz band rain scatter in the west.
The Eta Aquariids meteor shower peaked last week. In the decaying tail of activity, together with other lesser showers, this should keep an enhanced meteor input for the coming week.
The Sporadic-E season typically runs from May to mid-September and the daily jet stream blogs have started on www.propquest.co.uk.
As usual, the main season offers two periods of activity, one in the morning and the second from late afternoon to the evening. Remember, Es is not guaranteed since it depends upon many factors, but jet streams help, and these are shown on the website maps. Use the map clusters to find out where any activity is starting on 10m and then follow it up in frequency through the lower VHF bands.
EME path losses are at their maximum but falling after apogee on Friday, the 9th of May. Moon declination is negative, reaching a minimum this coming Thursday, so weâll have very short Moon windows and low peak elevation. 144MHz sky noise is moderate, increasing to high by next Friday.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 1st of May 2025
After the previous weekâs geomagnetic disturbances, as described in last weekâs GB2RS, the last seven days have been relatively quiet.
The Kp index has mostly been in the ones and twos, however the rise to a Kp value of four on Thursday the 1st of May could herald a return to unsettled conditions.
The solar flux index peaked at 170 on the 24th of April, before declining to 148 at the end of the month. HF conditions have been acceptable rather than outstanding and many stations struggled to work DX at times during International Marconi Day on the 26th of April.
Nevertheless, there is DX about including ZS8W Marion Island, TX9A Austral Islands and HD8G Galapagos Islands.
A look at the Proppy propagation prediction tool will help you work out the best times for making a contact with each station and on each band. You can find it by going to rsgb.org/propagation-tools
Looking ahead, a large sunspot has rotated into view. Now designated 4079, this region has returned and was previously sunspot region 4055. It has already emitted an M-class solar flare, and we may expect greater activity as it becomes more Earth-centric over the next week.
NOAA predicts that the solar flux index will climb again in the coming week, perhaps rising to between 160 and 165. Geomagnetic disturbances are also due to rise, with the Kp index forecast to reach five on the 5th and 6th of May.
If this becomes a reality, expect lowered MUFs and poorer HF paths, especially over the poles as the Kp index rises.
And finally, this week traditionally marks the start of the Sporadic-E season so keep an eye on 10m and 12m for short- and medium-range openings to Europe.
And now the VHF and up propagation news from G3YLA and G4BAO
The current spell of high-pressure Tropo weather weakened a little as last week ended and weâll see the return of unsettled conditions with showery rain, perhaps even the odd thunderstorm.
This is unlikely to lead to a total removal of high pressure and Tropo will still be worth looking for, especially over the western side of the UK. Some models place a new high just west of Britain during the coming week.
This means that the rain prospects are not great, although probably just enough for a hint of rain scatter in any isolated heavier showers.
The HF bands sounded a bit âwateryâ at times last week, which is a classic sign of potential aurora to explore on the higher bands. Look out for aurora in the coming week if the Kp index climbs above five.
Meteor scatter is worth thinking about and, after last weekâs Lyrids, we now have the Eta Aquariids shower peaking in the early hours of the 6th of May.
Remember that Sporadic-E ionisation is largely composed of long-lived meteor ions, so be on watch for Es openings. From now onwards through to mid-September, Sporadic-E will dominate the lower VHF bands, so check the clusters for signs of activity. Remember that Es starts on 10m and moves HF as an opening develops, even reaching 2m in the peak summer.
Unlike Tropo, Es events are often fleeting, so the best you can do is monitor conditions as the Es intensifies and be ready when it reaches the band you want. Donât forget to check the daily Es blogs on www.propquest.co.uk which discuss the potential links between location of jet streams and Es formation.
EME path losses are increasing, but apogee is still a week away. Moon declination passed maximum last Thursday so Moon windows are shortening along with reducing peak elevation. 144MHz sky noise is low all week.
And thatâs all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 24th of April 2025
We had yet another week of unsettled geomagnetic conditions. The Kp index peaked at 5.33 on the 21st of April as the solar wind speed hit just above 600 kilometres per second, and active geomagnetic conditions were observed.
This was caused by a massive coronal hole on the Sunâs surface, which measures nearly 700,000km in length. At the time of writing, part of it is still Earth-facing, but the Bz or interplanetary magnetic field is facing North, so its negative effects are not being felt.
The Kp index was down to 3.67 on the morning of Thursday, the 24th of April, but it wouldnât take much for the Bz to swing southwards and for the Kp index to rise again.
Meanwhile, the solar flux index has risen from a recent low of 148 up to 168. This has meant MUFs over a 3,000km path have reached 25 MHz at times, but have usually been slightly lower. If the Kp index can stay low, there is a good chance of higher MUFs being attainable, but we have probably seen the best of 10m propagation until the autumn.
Much of the recent DX has been worked on slightly lower frequencies, such as VP2VI British Virgin Islands on 40 and 20m, C5R The Gambia on 20 and 12m, and HD8G Galapagos Islands on 20, 17, and 12m. There is still the chance of DX on 10m, but it may be fleeting.
Next week, NOAA predicts that the solar flux index will stay high, perhaps reaching 170 to 175. We may get a slight respite from unsettled geomagnetic conditions from the 26th to the 30th of April, when the Kp index is forecast to be around two to three. However, unsettled geomagnetic conditions are forecast for the beginning of next month, with Kp indices of five or six on the 1st and 2nd of May.
And now the VHF and up propagation news from G3YLA and G4BAO
Next week, high pressure should dominate, meaning a chance of Tropo for much of the time which will probably favour paths to the east, to Scandinavia or northern Europe.
Rain scatter wonât have featured much other than over northwest Britain in recent days, and meteor scatter is reducing back to random activity, which tends to be better in the early hours before dawn.
The solar conditions have continued to keep the Kp index up, and there was a fine auroral opening last week on the 16th of April, so for more aurora, itâs still worth checking for when Kp values nudge above five.
As the end of April moves into May, we can start to give serious thought to the coming Sporadic-E season. Hesitant beginnings often show up on 10m and 6m, and, as usual, the digital modes will be best for any weak events. CW and SSB are just possible in the stronger openings, especially on 10m.
The background rule is that there are usually two preferred activity periods, one in the morning and a second in late afternoon and early evening. However, at the start of the season, there can be a lot of spread in the timings.
EME path losses are at their lowest with perigee today, Sunday the 27th, and the Moon declination is positive and rising. Moon windows will lengthen along with peak elevation, and 144MHz sky noise starts the week low but increases to moderate as the week progresses. From late Sunday to early Monday, the Sun and Moon are close.
And thatâs 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 wonât 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 youâve 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 thatâs 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 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 wonât 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 itâs 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 weâre 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 thatâs all from the propagation team this week.

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 âlonger a high lasts, the longer it will lastâ 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, itâs 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 weâre 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 thatâs all from the propagation team this week.

As part of its modernisation of the exam systems, the RSGB has introduced online forms for reporting possible errors found in exam questions. These forms replace the current procedure of writing to the Exam Department. RSGB Examinations Standards Chair Tony Kent, G8PBH, explained that there are two forms. The first can only be submitted by exam candidates and is to formally challenge questions in actual exams, where the outcome of a challenge may affect a candidateâs result. The second form can be submitted by anyone and is for informal queries of published exam questions, for example, in mock exams. A separate form is needed for each question that you challenge. Please check carefully that you are using the correct form, otherwise, it may delay the process. Your query will be considered by the RSGB Examinations and Syllabus Review Group, who will let you know the outcome. For more information and to find the forms, go to rsgb.org/exam-challenges
The next webinar in the RSGBâs Tonight@8 series will be with Nick Wood, M0NTV, on Monday, the 7th of April.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 27th of March 2025
Last weekâs 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 âtropo liftâ.
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 âblipsâ 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 thatâs all from the propagation team this week.

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 Moonâs 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 thatâs all from the propagation team this week.

To ask a question via video on Zoom youâll need to register in advance and give the topic of your question. Youâll have the chance to ask your question live with one follow-up question on the same topic. If youâd prefer to submit a written question in advance, you can do so via a form on the RSGB website. The third way to ask Board members a question is via the Live Chat function on the day. Whilst the Board will take as many questions as possible during the second part of the AGM, if you would like to ask a question about the formal part of the meeting, please submit a written question in advance or register to ask a question via Zoom. Full details of how to take part in the RSGB AGM, along with closing dates to submit a question, will be available from Wednesday the 19th of March via rsgb.org/agm

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 13th of March 2025
Weâve 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 donât 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 thereâs always the chance of random meteor scatter activity, particularly in the pre-dawn hours.
Itâs still a little early to mention Sporadic-E, but itâs 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 thatâs 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 Sunâs northern hemisphere have now departed. Nevertheless, the southern hemisphere is still supplying lots of spots so donât 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 weekendâs 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 thatâs 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 thatâs 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 â 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 yearâs 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 âA year in numbersâ 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.
Donât forget to submit your entry to the RSGB Construction Competition by Saturday the 1st of March. Youâll 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 Special Event news
On 26 February 2025, the 90th anniversary of the Daventry Experiment will be commemorated, marking a pivotal moment in the development of British radar technology. The Daventry Experiment had a lasting impact on both military strategy and civilian applications. To honour this milestone, several special event stations will be active. The Bawdsey Radar Museum will be hosting GB2BRS, with BRS representing Bawdsey Radar Station, whilst Coventry ARS from near Daventry will operate GB9ORE, with RE representing Radar Experiment. Chelmsford ARS from Great Baddow in Essex will activate GB9OCH with CH representing Chain Home since Chelmsford is where one of the original Chain Home radar masts still stands.
Special callsign S5701DX is running during February in memory of Slavko, S57DX who became a Silent Key last February. The station has been heard recently using CW and SSB on the HF bands. For more information visit QRZ.com
From the 1st to the 28th of March George, MM0JNL will once again be activating special event station GB0GTS. This year the station is active in support of the Great Tommy Sleepout. This national challenge aims to raise funds and awareness for all former UK service personnel who are living homeless. More details are available at QRZ.com and rbli.co.uk
Now the DX news
Datta, VU2DSI is operating from Lonar Lake in India until tomorrow, the 24th of February. This unique location was formed by the impact of a meteor around 550,000 years ago. The station will be active on the 40, 20, 15 and 10m bands using SSB. More information can be found at QRZ.com
Now the contest news
The CQ 160m DX Contest started at 2200UTC on Friday the 21st and ends at 2200UTC today, Sunday the 23rd of February. Using SSB on the 160m band, the exchange is signal report and CQ zone. USA stations also send their state and Canadian stations send their province.
The REF Contest started at 0600UTC on Saturday the 22nd and ends at 1800UTC today, Sunday the 23rd of February. Using SSB on the 80 to 10m bands, where contests are permitted, the exchange is signal report and serial number.
The UBA DX CW contest started at 1000UTC on Saturday the 22nd of February and ends at 1300UTC today, Sunday the 23rd of February. Using CW on the 80 10m bands, where contests are permitted, the exchange is signal report and serial number. Belgian stations will also give their section code.
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 thatâs all from the propagation team this week.

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 pagesThe 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 youâd 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 isnât 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 RSGBâs 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 yearâs British Science Week theme of âChange and adaptâ. If youâd 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 isnât just for younger audiences, it is open to all. If youâre 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 Societyâs 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 theâŻRegional RepresentativeâŻof 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 Sunâs 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 Earthâs 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 wasnât 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 thatâs 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 thatâs 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 Sunâs 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 Earthâs 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, itâll 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 thatâs all from the propagation team this week.

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 thatâs 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 â 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 thatâs all from the propagation team.

There are eight Regional Representative posts available for nomination in this yearâs 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 Societyâs 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. Youâll also find details about how to apply, alongside information on other roles, including the RSGB President and two ElectedâŻBoard DirectorâŻvacancies. 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 RSGBâs 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 youâll 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 youâre 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 Societyâs 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 Societyâs 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
Donât forget that the next event in the popular 145 Alive series will take place on Sunday the 26th of January 2025.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 9th of January 2025.
First, letâs take a look at last weekâs 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 didnât stay above 28MHz for long after sunset. MUFs plummeted to below 10MHz by 1800UTC on Sunday the 5th.
The message is clear â 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 thereâs 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 wonât 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 thatâs all from the propagation team.
