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

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

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

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of April 2024
We had another week with plenty of sunspots, and HF conditions were quite good in the second half.
Earlier, the Kp index reached 3 and 4, which didnât help maximum useable frequencies, or MUFs for short. For example, on Sunday the 21st, the Kp index rose to 4 and the MUF over a 3,000km path remained stubbornly below 21MHz until later in the morning.
This could have been due to a coronal hole on the Sunâs equator, which added to the solar wind. By Wednesday, conditions were nearly back to normal, with a Kp index below 2 and an MUF of more than 24MHz. By Thursday the improvement had continued, giving us an MUF of more than 28MHz by 0900UTC.
There have been many reports of 10m band DX being worked, including Sebastien, FK4AX and Pat, FK8HA in New Caledonia in the Pacific on SSB. Sebastien has just got his licence and is keen to work DX from the UK.
This shows that it is worth keeping an eye on the CW and SSB portions of the 10m band, which can often throw up surprises.
Next week, NOAA predicts that the solar flux index will decline to around 160. The Kp index is predicted to be around 2 to 3, but that may be wishful thinking. With 16 active regions visible on the Sunâs surface on Thursday, anything could happen. Only minor C- and M-class flares have occurred recently but, as we always say, it wouldnât take much for those to turn into X-class events.
So, make the most of quiet geomagnetic conditions when we have them as, by the time you read or hear this, we could once again have very unsettled conditions indeed.
And now the VHF and up propagation news from G3YLA and G4BAO
The cold, unsettled weather will ease its grip over the last few days of this week, ending the 28th of April, but only because the whole area of low pressure is moving across the country this weekend.
Low pressure remains close by for much of the following week and only a hesitant return of high pressure west of Ireland will improve things for western Britain at the end of the week.
The result is a chance of Tropo for western Britain next week, but it will probably be of limited quality since it is likely to form in cold, dry air across any temperature inversion.
The remaining option in such weather patterns is primarily rain scatter for those on the GHz bands. The many online weather radar displays can be used to highlight the areas of heaviest rain.
We are past the peak of the Lyrids meteor shower, but the Eta-Aquarids, with a Zenithal Hourly Rate of 50, peaks next Sunday the 5th around 2100UTC. Until then, rely upon random activity which tends to be better around dawn.
The Sun has been more active again recently, so monitor the clusters and Kp index for signs of geomagnetic activity and the chance of an aurora if the Kp index exceeds 5.
Sporadic-E tends to produce a few early examples in May ahead of its June peak. Check the DX clusters during the late afternoon or early evening as openings can be very brief early in the season. Start on the 10m band and, if short skip within Europe is present, move up to the 6m band. Digital modes are more sensitive so check FT8 reports to give clues as to where the chances are greatest.
For EME operators, the Moon is at minimum declination today, Sunday the 28th, meaning weâll have short Moon windows to start the coming week. Path losses are falling but perigee, when the Moon is at its closest point, is still over a week away. 144MHz sky noise is high this weekend, ending the 28th of April, but falls too low by the end of the coming week.
And thatâs all from the propagation team this week.

Dr Stewart Bryant, G3YSX to continue as RSGB Board ChairThe RSGB has vacancies for Regional RepresentativesThe Radio Communications Foundation is recruiting new TrusteesThe RSGB Board has met for the first time since the Societyâs AGM where three Directors were endorsed to serve as Nominated Directors on the Board and one was confirmed as elected unopposed. The new Board has chosen Dr Stewart Bryant, G3YSX to continue in the role of RSGB Board Chair until the 2025 AGM. You can find details of all RSGB Board Directors on the Societyâs website and the Board Liaison roles will be confirmed and added to the page in the coming weeks. Go to rsgb.org/board for more information.
At its recent AGM, the RSGB was delighted to confirm the unopposed election of five Regional Representatives. However, there are still vacancies for Regional Representatives in Region 11, which covers England South-West and the Channel Islands, and also Region 12 which is England East and East Anglia. These vacancies will be filled by co-option until the 2025 AGM. If you live in one of these areas and are passionate about amateur radio, keen to support local radio amateurs and clubs, and have the skills to lead a volunteer team of District Representatives in the region, this could be a role for you! To find out more, please contact Tony Miles, MM0TMZ who is the Board Liaison for the Regional Team via [email protected]
The Radio Communications Foundation is a small charity dedicated to encouraging people to take up radio as a hobby or, in the case of youngsters, considering an RF-based career. The RCF is proud to sponsor Arkwright Scholars, work with the RSGB and Bletchley Park to deliver radio-building workshops and make grants for various projects around the UK. Further information is available via the RCF website at commsfoundation.org The RCF is now looking to recruit a couple of new Trustees to help it deliver its aims. Applicants should have an interest in radio communications and be prepared to be involved in decisions over grant-making, delivering RCF projects and attracting charity funding. The RCF would particularly like to hear from anyone with links to secondary education in the UK. Expressions of interest and applications should be sent to [email protected] preferably by the end of June.
Following the introduction in February of the new Ofcom amateur radio licence conditions, the RSGB has continued to provide information and support to radio amateurs to help them make the most of the changes. This has included updates, club talks and a section of the AGM event focused on those licence changes. Go to the RSGB YouTube channel, choose the AGM recording from the âliveâ tab and then watch two sections. Firstly, the main Board Q&A begins just after one hour and eighteen minutes into the event and includes some licensing questions from members. Secondly, a section from just before two hours and thirty-three minutes focused entirely on the new licence conditions and included three videos and a full live Q&A with four senior RSGB representatives. The Society has also published a wealth of information on its website which you can find at rsgb.org/licence-review
Nigel Limb, M7FFU, had a motorbike accident in 2015 that left him with permanent brain damage and partially blind in both eyes, but this didnât stop him from pursuing his childhood dream of obtaining his amateur radio licence. In December 2023 he passed the Foundation Licence exam. In the early 1970s Sue Jacob, GW7YLS was a shortwave listener and interested in amateur radio, but it wasnât until she retired and discovered that the exams no longer contained Morse code, that she decided to get more involved. Within 18 months she had passed all three licence levels. One of the great things about amateur radio is that it is accessible to everyone. The RSGB is celebrating this by collecting stories of radio amateurs who have passed their Foundation licence, or progressed through the licence levels, and are now discovering new aspects of amateur radio to enjoy. If youâd like to read more about Nigel, Sue and others, go to rsgb.org/student-stories and, if youâd like to share your story with the Society, email [email protected] and the RSGB will use as many as possible.
A new amateur radio Facebook group has been formed for those who like getting out and about in motorhomes, campervans, and caravans. The group welcomes all radio enthusiasts. To find out more, or to join the group, search for âUK Motorhome and Amateur Radio Groupâ on Facebook.

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

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

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 4th of April 2024
Looking at the Sun on Wednesday the 3rd of April, you might be forgiven for thinking we are near sunspot minimum!
With a near-total lack of sunspots and a solar flux index of 112, the solar disk was looking pretty bare. Compare that with just two weeks ago when the solar flux index was sitting at 209 on the 23rd of March.
But never fear, there seems to be some activity coming up. Two active regions, AR3627 and AR3628, have just rotated into view, but in the meantime make the most of the geomagnetically-quiet conditions.
10m propagation is still holding up, although you may find that the band opens a little later in the morning and shuts earlier in the afternoon. The 4X6TU and VK6RBP IBP beacons were both audible at 0945UTC on Thursday the 4th, while China, Japan, Mongolia and Thailand were copiable on 10m FT8, even with a lowish solar flux index.
Higher HF band propagation from the UK has moved from favouring North America to north-south paths, notably to South Africa and South America.
Next week, NOAA predicts that the solar flux index will rise a little, perhaps starting at around 135 and finishing at around 150. Geomagnetic conditions should be reasonably quiet with a maximum Kp index of 3, unless we get a coronal mass ejection that could send it soaring.
As always, keep an eye on solarham.net for current conditions.
And now the VHF and up propagation news from G3YLA and G4BAO
There have been reports of trans-equatorial QSOs on 144MHz from Southern Africa to the Southern Mediterranean, but here in the UK we can only dream due to our northerly location.
The next period of weather is unfortunately shaping up to be the same as most of the recent ones, dominated by low-pressure systems driving active weather fronts across the British Isles.
It means that Tropo conditions seem unlikely to feature much through to the end of the coming week. Rain scatter for the GHz bands remains the mode of choice with help from some heavy April showers. Meteor scatter options are still best with random meteors before dawn, but we are getting closer to the April Lyrids shower later this month, so not long to wait now.
The solar conditions have subsided a little recently, but we remain in scope for further activity, especially since April can be one of the more active months for Aurora. Watch out for fluttery signals on HF or VHF bands, use the various clusters, or save the frequency of one of the northern beacons in your rigâs memory.
This is a good time to suggest updating your list of favourite beacons on the 10, 6, 4 and 2m bands since theyâll be useful for the upcoming sporadic-E season too.
Itâs a good time to take an early look at the sporadic-E prospects before it gets properly busy.
Some background rules which may help are to use propquest.co.uk to see where the jet streams are since Sporadic-E propagation is often associated with turbulence in regions of jet stream activity. Then look for a relatively low Kp index. The other main rules are related to timing. Usually, there are two windows of opportunity, one in the morning and a second in the late afternoon or early evening. However, at the beginning of the season, these are approximate.
Sporadic-E starts on the lower bands like 10m and, if strong enough, will gradually extend to the higher bands. The 10 and 6m bands are probably the ones to check this month.
For EME operators, Moon declination goes positive again on Sunday, which is also Moon perigee, its closest point to Earth, so weâll see lengthening Moon windows, increasing elevation and low path losses. 144MHz sky noise is low until Mondayâs total solar eclipse, then moderate 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 Wednesday the 27th of March 2024
What a tumultuous time we had last week. Active region 3614 produced an X1.1 solar flare and coronal mass ejection, or CME, in the early hours of the 23rd of March. This impacted Earthâs geomagnetic field sending the Kp index to 8 on the 24th of March.
There were simultaneous flares from active region 3614 and the larger region AR3615.
The solar wind speed reached more than 850 kilometres per second at the height of the geomagnetic storm, peaking at 880 kilometres per second.
The CME started to impact the Earth early in the afternoon of the 24th and, according to Digisonde data, its full effects on the ionosphere started to be felt by 1540UTC.
The large AR3615 sunspot cluster continues to evolve as it moves into the Sunâs southwest quadrant. Moderate flaring will remain likely in the short term with a lower chance for another strong X-class flare, although it is around the side of the Sun and is not considered a threat today, Sunday the 31st.
All this was not good news for HF propagation, which saw maximum useable frequencies over a 3,000km path plummet on the 24th to less than 18MHz. The ionosphere didnât fully recover until two days later, with the MUF struggling to get above 18MHz on the 25th.
It wasnât until the afternoon of Wednesday the 27th that we saw the 10m band behaving normally again with the Kp index back in the range of 1 to 3.
So, this is what can happen if we have an X-class flare and associated CME. We can expect more of the same to come.
Next week, NOAA predicts that the solar flux index will remain high at around 175 to 190. Unsettled geomagnetic conditions are forecast from the 3rd to the 5th of April when the Kp Index could rise to 4.
But keep an eye on solarham.net for a near real-time guide to current solar conditions.
And now the VHF and up propagation news from G3YLA and G4BAO
The period leading up to the Easter Weekend, and the following week shows up on the forecast charts as dominated by low pressure, feeding several periods of rain and showers across the country.
This unfortunately means that Tropo is again off the menu of weather-related VHF propagation.
Of course, wet weather is usually very supportive of rain scatter propagation on the GHz bands and this prolonged period of rain or showers will give the UHF and SHF operators something to occupy their time.
Meteor scatter prospects are once again just random, which tends to be better in the hours just before dawn. We can start to look forward to the April Lyrids, which are active in the second half of April with a peak around the 22nd. Itâs worth checking out the operating conventions and frequencies now so that you can be ready.
Strong aurora has been reported recently, with a Kp index of 8, and a quick listen for fluttery signals on the 80m or 40m bands is often a good clue if you donât have access to the Kp index at the time.
The main mode of interest for the coming months is Sporadic-E and some early propagation is possible, mainly on digital modes on the 10m or 6m bands, but probably very fleeting.
During the summer Sporadic-E season, it's well worth checking the propquest.co.uk graphs to see what is occurring and get an idea of how it may relate to jet stream weather patterns by cross-checking with the Sporadic-E blog upper air charts.
The Sporadic-E Probability Index, or EPI, maps are also potentially useful to see how the favourable regions change with time. In the current pre-season period, itâs more typical to find trans-equatorial propagation, or TEP, as an exotic mode offering paths to the south into South Africa and possibly into South America.
For EME operators, Moon declination reaches minimum on Easter Monday, so weâll see short Moon windows with low elevation. Path losses are falling all week and 144MHz sky noise is moderate, rising to a peak of more than 3,000 Kelvin on Easter Monday before returning to low levels.
And thatâs all from the propagation team this week.

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

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

The Edinburgh 23cm microwave beacon GB3EDN is back on the air after a move to a new location on the south side of Edinburgh. It has moved about 1.5km south from its previous site in the University of Edinburgh, Kingâs Buildings Campus. The operating frequency is 1296.990MHz. It sends its callsign and QRA locator in both FSK and JT4 once per minute. The new site is about 200m higher than the previous site and it is hoped that coverage is somewhat improved. It has a clear view from the northwest through to the east, giving good coverage up the east coast and across the North Sea to Scandinavia. It is also hoped that there will be better propagation to the south from the new site.

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

The Notice includes the resolutions and information about the three Nominated Directors who are being put forward for endorsement by RSGB members. You can also read the minutes of last yearâs AGM. Voting opens on Wednesday the 13th of March. On that same day, you will be able to submit a question for the RSGB Board via a web form or register to ask a question via video on Zoom. For more information go to the Societyâs website at rsgb.org/agm
The RSGBâs Propagation Studies Committee has released a new HF beacon list, with the 10m band listings completely revamped. The old list, which was started by Martin Harrison, G3USF Silent Key, had been added to over the years but was getting out of date. The only way to make it more accurate was to start again. The Propagation Studies Committee made use of the Reverse Beacon Network which wasnât available when the list was originally created, plus listenersâ contributions from around the world. The new beacon list can be found at rsgb.org/beacons
Have you wondered what happens at a VHF National Field Day? Would you like to take part in one? In this monthâs Tonight@8 webinar, on Monday the 4th of March, the RSGB offers two different perspectives. Firstly, RSGB VHF Contest Committee member Richard, G4HGI will talk about how the RSGB VHF Contest Committee uses the VHF Survey and other tools to formulate the rules and calendar for all VHF Contests, with specific emphasis on VHF National Field Day. Secondly, three members of the Lothians Radio Society, GM3HAM will explain how they organise and operate these hilltop events within the Scottish borders. The club has made a short, professional film capturing their 2023 VHF National Field Day weekend. They will show clips of that and of an old cinema film to show how this looked from a technical standpoint at much earlier club competition events in the 1970s. This will be a great evening so put it in your diary and be inspired! You can watch and ask questions live on the RSGB YouTube channel or a special BATC channel. Go to rsgb.org/webinars to find out more.
The RSGB has made two safeguarding announcements. Firstly, the Societyâs safeguarding policy has been revised in line with modern practices and you can find it on the RSGB website at rsgb.org/policies Secondly, if your club relies on the RSGBâs affiliated club insurance for activities that may have a safeguarding requirement, it is important that you are aware of the conditions in Section 10 of that insurance. You can find the insurance details in your club portal on the RSGB website.
The Radio Society of Harrow is running a one-day classroom-style Foundation course on Saturday the 23rd of March at its venue in Watford. If you know anyone who would like to join the course, please tell them to email Brian, G3YKB at [email protected] There will be an optional extra session on the morning of the 24th.
Following complaints from some members, the RSGB has investigated a problem with the non-delivery of RadCom on Guernsey and the Isle of Man. It seems that following changes at Royal Mail, the labelling requirement for these copies was incorrectly applied by the printers and these copies didnât go through the postal system correctly. The Society is sorry that this error has occurred and apologises for any inconvenience caused. It has, of course, asked its printers to ensure that there is no repetition of this problem, and the printer has paid for the two missing copies to be sent to each RSGB member in those areas. If your RadCom doesnât arrive in future, please email the RSGB membership team via [email protected] so they can send a replacement and track any wider problems.
Those who enjoy constructing and operating with low-power devices will be interested to know that a QRP conference is taking part in Rennes in the northwest of France on the 18th of May 2024.

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

GB2RS News
Sunday the 25th of February 2024
The news headlines:
New amateur radio licence conditions are effectiveAmateurs are reminded to carry out EMF assessmentsThe 2024 Band Plans have been publishedOfcom has released its final decisions following its consultation on the amateur radio licensing framework last year. Revised licence conditions became effective on Wednesday the 21st of February 2024. The changes to licence conditions include the optional use of Regional Secondary Locators, increased transmitter power levels and provide a greater opportunity to bring newcomers into amateur radio. There are approximately 100,000 amateur radio licences issued by Ofcom in the UK. Ofcom says that it will shortly be contacting all licensees to provide each with their new licence document. Ofcom is aiming to reissue all UK amateur radio licences by the autumn of 2024. To help this process run as efficiently as possible, please ensure that your contact details are up to date in the Ofcom licensing system. Further updates to the amateur radio licensing framework, including the issuing of M8 and M9 Intermediate callsigns, will be rolled out in two more phases later this year and in the 2024/25 year. A video entitled âUpdating the amateur radio licensing framework: RSGB overview of key changesâ is available in the Ofcom playlist on the RSGBâs YouTube channel which you can find at youtube.com/theRSGB In it, RSGB General Manager Steve Thomas, M1ACB and RSGB Spectrum Forum Chair Murray Niman, G6JYB discuss the impact of the new rules. They also describe how the RSGB worked with Ofcom before and during the consultation period to arrive at the best outcome for all UK amateurs. Steve, Murray, and many people across the RSGB have also worked hard to engage with individual amateurs, and amateur radio clubs and groups, to help them prepare for the licensing changes. The RSGB will continue to release information and support for radio amateurs as we all adapt to the new arrangements. You can read more details and guidance on the Ofcom website at tinyurl.com/ARFEB2024 or via the RSGB website at rsgb.org/licensing
Given that increased transmitter power limits are now available to UK licensees, all amateurs are reminded that they are required to carry out EMF assessments. To help you do this, advice and an online EMF calculator can be found at rsgb.org/emf
The RSGB Band Plans for 2024 were published in the March issue of RadCom. They are also available via the RSGB website at rsgb.org/bandplans This yearâs changes support the new Ofcom licensing framework and guidance, particularly in the VHF and UHF bands. All amateurs are reminded to consult the Band Plans before operating.
The list of amateur radio events taking place in British Science Week and the resource suggestions are growing. GB3RS, the radio station at the RSGB National Radio Centre at Bletchley Park could be available for QSOs with stations operating as part of British Science Week. Contact the RSGBâs BSW coordinator, Ian Neal, M0KEO at [email protected] and he will link you with the NRC Coordinator Martyn Baker, G0GMB to make your arrangements. Please continue to send to Ian the resources youâd like to share and details of British Science Week events youâre organising, including the times youâll be on the air. The RSGB would like to inspire as many people and groups as possible to get involved! You can access all event and resource details on the RSGB website at rsgb.org/bsw
The RSGB has been trialling paper wrappers for RadCom as part of its plans to be more environmentally friendly. The Society has been collating feedback and is aware that there have been particular problems with the glueing of the RadCom wrappers this month. Please be assured that the RSGB is discussing this with its supplier to try to resolve the problem before the next issue.
During a year when the global landscape shifted once more, with conflicts across the world and economic difficulties touching the lives of individuals, the RSGB was pleased to see that the amateur radio community continues to thrive. It may have changed shape and adapted with the times, but the Society has been there not only to support its members but to defend the spectrum and provide information for all radio amateurs. In the March RadCom, there is a feature called âA year in numbersâ which shows some of the great things to celebrate, in which RSGB HQ staff have often led the way. There is an infographic and a short video with the highlights, and you can read the fuller story from page 40 in RadCom and on the website. Go to rsgb.org/strategy-updates and click on â2023 - a year in numbersâ. The April RadCom will show in detail the work of the RSGB committees and other specialist volunteers.
The amateur radio licence exams will be updated in line with the new licence conditions decided by Ofcom this week. Further information about the timing of those changes can be found on the RSGB website at rsgb.org/syllabus2019

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

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

The outcome of the RSGB 2024 Board and Regional Team election processRSGB challenge for British Science Week announcedRSGB Spectrum Forum updatesThe RSGB has announced the outcome of its 2024 Board and Regional Team election process. These results come into force at the RSGB 2024 AGM and, until that time, the current Regional Representatives remain in their roles. The announcement also contains news of the Nominated Directors put forward for endorsement by the RSGB membership next month, as well as two co-options to the RSGB Board, effective until the AGM. For full details of the announcement and the candidates go to the RSGB AGM web page at rsgb.org/agm
The theme of British Science Week this year is Time. Both time and the closely related concept of frequency, are of vital importance to radio communications. The RSGB has announced a new challenge for British Science Week linked to this theme. The challenge has categories for every age group and the winner of each group will win a prize. The deadline for entries is the 1st of September and the results will be announced at the RSGB Convention in October. The challenge is as follows: âUsing readily available components, material or other resources, provide a method of either measuring the frequency of a radio frequency source or signal or providing a time reference to a radio operator or radio systemâ. For more details about the challenge, as well as activities to inspire you and resources to help you take part in British Science Week, go to the RSGB website at rsgb.org/bsw
A busy year has seen several online Spectrum Forum meetings. Two meetings held in January considered the Ofcom notice period for ârepresentationsâ and areas where band plan adjustments would be needed, as well as more regular items such as annual group reports.
The RSGB website now has these details online. The RSGBâs reply to Ofcom has been added to its special focus page on the Ofcom licence review. Along with other recent representations, this will enable Ofcom to finalise the new licence later this month. The RSGB Spectrum Forum pages have also been updated with the January 2024 group reports and meeting notes, which included the discussions on the provisional changes. To read more, visit rsgb.org/spectrumforum
As previously announced by the RSGB Examinations Standards Committee Chair, Tony Kent, G8PBH, the amateur radio licence examinations will need to change to reflect the changes to the licence conditions announced by Ofcom. The scale of the licence changes will have a significant impact on Section 1 of the syllabus, âLicensingâ, and a small impact on Section 7, âOperatingâ. Ofcom is currently reviewing representations and will publish its final decision, including the final version of the licence, before the 21st of February. The new licence will come into effect before work on the syllabus and examination question bank is completed. The RSGB Examinations Standards Committee has gained approval from Ofcom to continue to examine the current licence conditions for a period of six months following the publication of the new licence. This will allow trainers time to update their courses in line with the new syllabus, and allow candidates that have started their training under the current licence conditions to complete their courses and take the exam. It is expected that examinations of the new licence conditions will begin on the 1st of September 2024. For full details, see the exam announcements page on the RSGB website.

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

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

The news headlines:
The RSGB election deadline is coming upRSGB Build a Radio workshop planned at Bletchley ParkRegistration for SOS Radio Week is openThe deadline for nominations in the RSGB elections is next Wednesday, the 31st of January. If you would like to stand for the one elected Director role, or any of the eight Regional Representative vacancies, you will need to complete the nomination process by 2359UTC on Wednesday. Full details of the process are on the RSGB website at rsgb.org/election The Society would encourage anyone with a passion for amateur radio, and a desire to support the amateur radio community, to look at the candidate information and consider stepping forward for one of these roles. Youâll find full information about the skills and experience needed in the candidate packs, and there is still time for an informal chat about the roles and responsibilities if youâd like one. But donât delay as late applications wonât be accepted!
As part of its British Science Week activities, the RSGB is organising two build-a-radio workshops at Bletchley Park on Sunday the 17th of March. Funded by the Radio Communications Foundation, these fun workshops are a great way for young people to try a practical amateur radio activity. The sessions are for youngsters aged 11 to 18 who will build their own VHF FM broadcast receiver using simple tools. The workshops cost ÂŁ11 for the participant, and if you are an adult accompanying a participant who is aged 16 or under, you will receive free admission to Bletchley Park. These workshops are always very popular so book now if you know a youngster who would like to take part. Go to the Bletchley Park website at bletchleypark.org.uk then choose the Whatâs On option from the top right-hand menu.
SOS Radio Week is an annual event that takes place throughout May to celebrate the work of the volunteers from the Royal National Lifeboat Institution, Independent Lifeboats and National Coastwatch Stations around the British Isles. Members of these organisations save many people who are in danger along, and around, the thousands of miles of coastline and further out to sea. This year is the 200th anniversary of the founding of the RNLI, so SOS Radio Week is being branded âSOS Radio Week 200â for those operators who are supporting the RNLI during the event. Participants can operate from home, a public location, or a lifeboat or Coast watch station, with the appropriate authorisation from the station manager. A commemorative certificate will be available to all official stations that record their contacts on the website, together with awards for the top individual and club, or group, stations on each band from 160m to 70cm. Registration for individual and group operators is now open via sosradioweek.org.uk
The RSGB has released a further three presentations from its 2023 Convention. In the first, Professor Simon Watts, G3XXH gives a fascinating presentation about VHF airborne radar and the design and performance of these early systems in World War II. The other two presentations focus on the World Radiosport Team Championship which the UK will be hosting in 2026. The WRTC is held every four years and is considered to be the Olympic Games of radio contesting. At the RSGB Convention, WRTC Chair Mark Haynes, M0DXR gave an overview of what is being planned and how people can get involved either as a spectator, volunteer, competitor or referee. John Warburton, G4IRN gave his perspective on what it is like to be a WRTC referee. The full WRTC planning team also gave an update recently on an RSGB Tonight@8 live webinar. You can see all of these presentations on the RSGB YouTube channel at youtube.com/theRSGB
RadCom Basics aims to help newcomers to amateur radio develop their knowledge and experience. Others enjoy reading it as it helps remind them of things they have forgotten or practise a skill they have not used for a while. The January 2024 issue of RadCom Basics is now available. It contains articles that provide advice on getting started with Bunkers on the Air, working on the 160 and 80m bands, constructing a multi-band vertical antenna, and more. You can find RadCom Basics at rsgb.org/radcom-basics
The latest issue of RadCom Plus, the online magazine for the more technically-minded radio amateur, was published this week. The first article, by Tom Alldread, VA7TA, is about how to make a protection filter for an SDR or VNA. Following this is a contribution from Sheldon Hutchison, N6JJA who discusses how to make an effective antenna noise canceller. You may recall the article by Andy, G0FVI in Octoberâs RadCom which discussed the principles of antenna noise cancellation. Sheldon investigates exactly how the canceller should work, and his investigations have resulted in his superior design which you can construct for yourself. The third article, by Michael Toia, K3MT, is all about understanding the relationship between a train of square pulses and the harmonic content of its frequency spectrum, not with complicated mathematics, but by using an entirely diagrammatic approach. Those less familiar with mathematics might especially find this article helpful. This issue of RadCom Plus ends with Andy Nehan, G4HUE discussing the design of analogue power supplies. Members of the RSGB can access RadCom Plus via rsgb.org/radcom-plus

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 25th of January 2024
We dodged a bullet last week when a coronal mass ejection, or CME, was predicted to be heading our way. In the end, it came to nothing.
The CME observed on the 20th of January was expected to pass Earth and deliver possible G2 storm conditions. But a solar wind enhancement, possibly associated with the plasma cloud passing near Earth, saw the Kp index rise to only 3.67 on Wednesday the 24th.
The many solar flares, and associated coronal mass ejections, over the past few days make it difficult to give a reliable geomagnetic forecast. Over the past seven days, there have been more than 60 C-class and 18 M-class flares, typical for this point in the solar cycle. Sunspot-wise, the solar flux index has remained high, being more than 170 all week.
Critical frequencies have often exceeded 11MHz during daylight hours, which means the 30m band, as well as the 40m band, should be open around the UK. However, nighttime critical frequencies have fallen below 4MHz, meaning that even the 80m band struggles at times.
We mentioned last week that the NCDXF beacon VK6RBP in Australia had been heard on 28.200MHz. If youâve copied VK6RBP you might be interested in trying for some other lower-power Australian beacons on the 10m band. Try listening for the 8W VK4LA/B on 28.206MHz in Brisbane, or perhaps the 10W VK4RST, which is 550km north-west of Brisbane, on 28.266MHz.
Next week, NOAA predicts the solar flux index will be in the range of 155 to 175. Geomagnetic conditions are forecast to be quiet, other than on the 29th of January when the Kp index is predicted to rise to three. But, as always, keep an eye on solarham.net for a near real-time report.
And now the VHF and up propagation news from G3YLA and G4BAO
Today, the 28th, sees the UK recovering from the two named storms and just getting settled into moving high pressure across northern France, with a second centre crossing central Britain early next week. This offers a chance of Tropo, especially in the south, while fronts continue to affect Scotland.
After the middle of the coming week, a more unsettled pattern returns with fronts crossing the country, which might bring some rain scatter for the GHz bands. But, in general, the picture remains unsettled into the end of the week and doesnât look too exciting for the 432MHz Affiliated Societies Contest on Sunday the 4th of February.
Other propagation modes that are worth considering are all relatively low-key in the transition into February. This means that meteor scatter is best looked for in the early pre-dawn period when random meteor activity peaks.
The other chance might be aurora, and this is simply about checking the behaviour of the Kp index, which measures the disturbance of the earthâs magnetic field by solar activity. Kp indices higher than six are a good sign for aurora.
It looks like we are in a quiet period for Sporadic-E propagation.
For EME operators, Moon declination is positive and falling, going negative again on the 30th. Path losses reach their maximum at apogee on Monday the 29th, then start to fall again. 144MHz sky noise is low all week.
And thatâs all from the propagation team this week.

The news headlines:
British Science Week is approachingUpdates on the RSGBâs Strategic PrioritiesRSGB election deadline reminderThis yearâs British Science Week runs from the 8th to the 17th of March with the theme of Time. This event is a fantastic opportunity to raise awareness of amateur radio in your local area. The RSGB has some great activity ideas you could try at your local school, Scout or Guiding group or local youth club. Go to the web page at rsgb.org/bsw and click on the activity titles to find everything you need to know to be able to run that activity. Several radio clubs from across the UK have already planned outreach activities for British Science Week and the RSGB hopes its resources will inspire you to get involved too! RSGB volunteer John Hislop, G7OHO has provided these ideas but the Society would love to add other activities to enthuse young people about wireless communication. If you have an amateur radio activity on the theme of Time that youâd like to share, or if youâd like to get involved but arenât sure how to start, please direct enquiries to the RSGB British Science Week contact, Ian Neal, M0KEO. Ianâs contact details will soon be available at rsgb.org/bsw
At the Discussion with the Board session at the RSGB 2023 Convention, the RSGB President, John McCullagh, GI4BWM confirmed that the Board would keep members updated regularly on progress with the new strategic priorities. Two updates have now appeared in the January and February issues of RadCom and they are also available to read on the RSGB website. These updates highlight some important activities and achievements as well as new plans, so the Society encourages every member to take the time to read them. Go to rsgb.org/strategy and choose the âStrategy priorities updatesâ option from the righthand list. Further updates are being prepared so do check back regularly or look out for them in each RadCom. You can also watch the Discussion with the Board Convention session on the RSGBâs YouTube channel at youtube.com/theRSGB
The deadline for applications for the one elected RSGB Board Director position and eight Regional Representative roles is Wednesday the 31st of January. Amateur radio needs a strong and active national society so donât leave it to everyone else, step forward for one of these roles and play your part in the future of the RSGB. You'll find guidance and candidate forms on the RSGB elections web page at rsgb.org/election as well as contact details if you want an informal chat before standing for election.
A reminder that the RSGB is looking for four licensed radio amateurs to help raise the profile of wireless communication amongst young people across the UK. We have had a good response, but weâd still like to hear from prospective volunteers in Northern Ireland and Wales. These volunteer Youth Country Representatives will represent the RSGB at externally organised events and will plan and deliver outreach activities. If you have plenty of ideas, a passion for getting young people involved in amateur radio and experience of running small-scale events, we would be very keen to hear from you. The deadline is Friday the 16th of February. For full details, see rsgb.org/volunteers and for an informal discussion, please email RSGB Board Director, Ben Lloyd, GW4BML at [email protected]
GB2RS began broadcasting via the Esâhail-2 amateur satellite in May 2021. Every Sunday at 0800UTC you can hear the latest RSGB news on the dedicated narrow-band QO-100 transponder frequency of 10489.855MHz.

Chris Deacon, G4IFX has been awarded a PhD from the University of Bath after completing research on propagation. His thesis was entitled: âRadio propagation through ionospheric Sporadic-Eâ. This part-time work over many years involved looking at Sporadic-E on the 6m band, including making novel measurements of signal amplitude, phase, derived Doppler, polarisation and potential time delay to discover the nature of sporadic-E propagation at VHF frequencies. The RSGB Propagation Studies Committee congratulates Chris on this fantastic achievement. You can find out more by searching for Chrisâ name on the University of Bath research portal at researchportal.bath.ac.uk Chris has done a number of presentations about propagation at RSGB Conventions over the years, which you can see on the RSGB YouTube channel at youtube.com/theRSGB

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

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

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