GB2RS News
Sunday, the 28th of September 2025
The news headlines:
What are your must-see presentations at this year’s RSGB Convention?
The RSGB invited the MP for Buckingham and Bletchley to the RSGB National Radio Centre for a private visit
Listen out for today’s special 70th anniversary GB2RS broadcasts
Before we begin today’s news bulletin, we would like to share a special message from the RSGB President Bob Beebe, GU4YOX, to mark the 70th anniversary of GB2RS. Bob says, “It is with a profound sense of respect and appreciation that today we mark the 70th anniversary of the GB2RS News service. Since 1955, volunteers have given their time and their voice to keep our radio community informed, connected, and inspired. For many of us, GB2RS has been a constant and familiar presence in our radio lives. On behalf of the RSGB, I extend my heartfelt thanks to all who have played a part in this remarkable story for the last seventy years. Today, we honour their legacy and reaffirm our commitment to the values and spirit that the GB2RS News service so proudly represents.”
 And now we move to today’s news items.
The programme for this year’s RSGB Convention has nearly 50 presentations for you to enjoy, including leading industry speakers such as Mike Walker, VA3MW from FlexRadio and Hans Summers, G0UPL from QRP Labs. There will also be well-known names such as Neil Smith G4DBN, RadCom Technical Editor Peter Duffett-Smith GM3XJE, Brian Coleman G4NNS and Walt Hudson K4OGO, known to many as ‘Salty Walt’. This annual RSGB event is your only opportunity within the UK to have access to this level of knowledge, learning and networking opportunities. As well as a packed full lecture programme, there will be nearly 20 special interest groups in attendance, so if you are thinking of pursuing a different area of the hobby, this is the perfect time to explore your options. To guarantee a place, you will need to purchase a ticket online via rsgb.org/convention before advance sales close on Sunday the 5th of October. Buying your ticket online not only guarantees your place, but it also saves you money when compared to on-the-door ticket prices. If you are arriving on Friday, why not join a private tour of Bletchley Park at 2.30 pm, which has been arranged especially for Convention attendees. In addition to this, and new for this year, RSGB National Radio Centre volunteer Patrick, 2E0IFB, will be running an informal introduction on getting started with low-earth orbiting satellites. The RSGB Convention takes place from the 10th to the 12th of October at Kents Hill Conference Centre in Milton Keynes.
The RSGB was pleased to welcome Callum Anderson, MP for Buckingham and Bletchley, to the RSGB National Radio Centre at Bletchley Park last week. Callum enjoyed seeing the history of radio, watching live CW contacts and listening to his voice coming back from space, having been relayed via a satellite. Callum was invited to meet a small group of senior RSGB representatives who emphasised the important role of amateur radio in encouraging young people into an engineering career. Getting involved in Science, Technology, Engineering and Maths activities gives a great foundation that could lead some young people to follow in the footsteps of radio amateur pioneers who led the development of many wireless technologies that we rely on today. Most importantly, the visit gave the RSGB an opportunity to show the problems that ElectroMagnetic Disturbance can cause to wireless reception. Examples of EMD include household appliances, Broadband FTTC and green energy from solar panels and windfarms, where the signal levels are thousands of times stronger than the expected levels given in ITU recommendations. EMC Chair John Rogers M0JAV and Board Chair Stewart Bryant G3YSX explained that unless the year-on-year increases in background noise are stopped, many critical services and infrastructures could be impacted soon, just as the amateur radio bands are today. The RSGB looks forward to meeting again with Callum, who is the Parliamentary Private Secretary for Science, Innovation and Technology.
Don’t forget to listen out for three special one-off broadcasts from the RSGB National Radio Centre today. The broadcasts are part of the celebrations, which are taking place to mark the 70th anniversary of GB2RS. Listen out at 1 pm, 2.30 pm and 4 pm. Go to rsgb.org/gb70rs  for details of frequencies and newsreaders. All listeners are welcome to join the pre- and post-News nets, which will be operating using the special event station GB70RS.
The RSGB LoRa high-altitude balloon launch took place on Saturday, the 20th of September and was a great success despite tricky weather conditions, which included rain and high winds. The balloon soared at a peak altitude of 48,556 feet before landing in a remote location in the Thursden Valley. Winners of the competition to win a £200 Moonraker voucher will be announced at the RSGB 2025 Convention on Sunday, the 12th of October. If you’re wondering what you can do with your LoRa tracker now that the RSGB challenge has finished, go to rsgb.org/lora-balloon for a handy guide on how you can continue the fun. If you took part and would like to be included in a special feature in the December edition of RadCom, send your photos and a short summary of your activity to comms@rsgb.org.uk by Wednesday, the 1st of October.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 25th of September
Last week was good for HF propagation for a number of reasons. Firstly, we are now entering autumn, which offers better propagation prospects than summer. Secondly, the solar flux index has remained high at up to 184 as of last Thursday, the 25th.
We had a week of near-normal geomagnetic conditions, with a low Kp index, no Earth-directed coronal mass ejections, and a relatively quiet solar wind.
These have all combined to give excellent HF propagation, including openings on the 10m band using FM and transatlantic 10m contacts being possible in the afternoon.
The maximum usable frequency, or MUF, over a 3,000km path, according to Propquest, has mainly been in excess of 30MHz during daylight hours.
The KQ2H repeater in upstate New York, with an output frequency of 29.620MHz, has been loud at times in the afternoon and is a good indicator of HF propagation. Expect it to get better as we enter October. Other US stations have also been heard on the 10m band using FM, including one in Ohio.
Steve, G0KYA, was surprised to hear the GB3XMB 10m beacon on 28.287MHz from Waddington, Lancashire this week. Steve remarked that it is 175 miles to Norfolk as the crow flies. He said that the signal didn’t sound like backscatter, so that’s quite a distance for 10m ground wave.
Another DX worked, according to CDXC, included FP5KE, the St. Pierre and Miquelon DXpedition. The station could be heard on everything from Top Band to 10m.
V6D in Micronesia has been worked on the 40 and 17m bands using CW.
Other highlights include D2USU in Fiji on the 12m band using FT8, and 9Y49R in Trinidad and Tobago on the 10m band using FM.
Next week, NOAA predicts the solar flux index may fall to the 159 to 170 range. Geomagnetic conditions are predicted to be poor tomorrow, the 29th, with a Kp index of 5, and again between the 3rd and 5th of October, also with a predicted Kp index of 5. Expect decreased MUFs for a few days until the ionosphere recovers.
And now the VHF and up propagation news from G3YLA and G4BAO
The next week or so looks to be typical for autumn. It will be a mix of Atlantic weather systems bringing lows and their fronts, which may offer some rain scatter for those on the GHz bands.
The other side of the coin is areas of high pressure or mostly weak ridges, in this case mainly affecting the south and east of the country. This is the point where Tropo operators can move in with paths probably favouring the North Sea and Scandinavia up to this weekend and then across to the continent and down to Spain during the coming week.
It is worth remembering that Tropo can exist throughout the 24 hours across water and along coasts like the North Sea and English Channel, although the portion of a path overland can weaken during daytime.
The meteor scatter prospects remain in the random territory, so they are best in the early morning.
Recent activity with geomagnetic disturbances suggests that aurora should continue to be part of the operating list in the coming week. Check for a hollow note or warble on HF signals and for a Kp index greater than 5, then consider turning your VHF arrays to the north.
For EME operators, Moon declination reaches its minimum tomorrow, the 29th, so from then on, we will see lengthening Moon windows and increasing peak elevation. The Moon’s distance from Earth started to decrease after apogee on Friday, the 26th, meaning path losses are falling. 144MHz Sky noise will be high today, the 28th, and peaks at around 2800 Kelvin tomorrow, the 29th, before dropping back to low for the rest of the week.
And that’s all from the propagation team this week.

The news headlines:
Secure your ticket for the RSGB 2025 Convention before online ticketing closes
A reminder to identify yourself clearly when operating
The RSGB Outreach Team launches its first official DMR Youth Net
Tickets for the RSGB Convention at Kents Hill Conference Centre in Milton Keynes are still available to purchase online, but hurry as advance sales close on Saturday the 4th of October. You will be able to buy a Convention ticket on the door but not at the reduced rate that is available now. Your ticket will give you access to numerous presentations including two on the funding available to interesting and innovative amateur radio projects. The RSGB Legacy Fund supports a wide range of projects and Legacy Committee Chair, Richard Horton, G4AOJ will give some recent examples that have been allocated funding. He’ll also talk you through how the application and approval process works. The California-based Amateur Radio Digital Communications foundation has its roots in amateur radio and the technology of internet communication. Steve Bunting, M0BPQ and Chris Smith, G1FEF will give an overview of ARDC’s grants which are also open to international charities, non-profits, schools and universities. If you’re thinking of a new project that would benefit amateur radio or help to bring it to new audiences, these are two presentations you won’t want to miss! Find details on these and all the other Convention presentations via rsgb.org/convention  You’ll also find a new web page outlining what else is happening during the weekend. If you’re attending the Convention for the first time, then pop along to the RSGB’s new ‘welcome desk’ on the Friday evening from 6.30pm to 7.30pm and then from 8pm to 9pm. The desk is aimed at first-time or solo attendees, although anyone can come and say hello. A member of the RSGB HQ team and other RSGB volunteers will be on hand to greet you and introduce you to like-minded people, and act as a familiar face throughout the weekend if you need any help. The RSGB Convention takes place between the 10th and 12th of October.
Every radio amateur knows that it is important to identify yourself clearly when operating. This includes the mandatory use of a Regional Secondary Locator, or RSL, if you hold an Intermediate callsign in the 2-series. For example, your callsign would start with 2E0 if you’re in England or 2M0 if you’re operating in Scotland. This mandatory use of the RSL is shown in the Ofcom licence conditions. You can find a link to that document on the RSGB licence updates web page at rsgb.org/licence-review

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 18th of September 2025.
Last week we said that it looked like someone had thrown a switch on the Sun and all the sunspots had vanished. Well, this week we’re pleased to report they’re back!
We have eight sunspot groups, spread evenly throughout the Sun’s hemispheres. Interestingly, the northern hemisphere sunspots are close to the equator, which is what you would expect at this point in the latter part of the solar cycle. The southern spots are somewhat higher in latitude, perhaps indicating that there might still be the potential for a double peak.
On Thursday the 18th, the solar flux index stood at 147 and the Kp index at 2. This suggests that HF conditions might be pretty good, at least until the next geomagnetic disturbance.
There have been no M- or X-class solar flares over the past week.
The solar wind speed dropped from a high of 800 kilometres per second on Tuesday the 16th, to a more reasonable 538 kilometres per second on Thursday the 18th. However, the Bz has been pointing south at times, which can cause problems with a raised Kp index.
The maximum useable frequency, or MUF, over a 3,000km path generally allows for operation between 21 and 24MHz during daylight and 7 and 10.1MHz at night. At 0845UTC on Thursday the 18th, a quick check of the NCDXF beacons on 21.150MHz showed reception of CS3B in Madeira and 4X6TU in Israel.
On 24.930MHz, 4S7B in Sri Lanka, ZS6DN in South Africa, and CS3B in Madeira could be heard. On 28.200MHz the only audible beacon was 4X6TU in Israel.
The NCDXF beacons are a quick way to check worldwide HF propagation in just three-minutes per band, from 20 to 10m. For more details visit ncdxf.org/beacon
HF DX this week has included FP5KE on St Pierre and Miquelon, which is operating until the 26th of September. PJ7K on St. Maarten, which is active until the 22nd of September, was worked; and VK9NT on Norfolk Island, which is operating until the 27th of September, also made it into UK logbooks. Check the DX cluster for the latest spots.
Next week NOAA predicts the solar flux index will remain in the range of 125 to 135. The Kp index is forecast to remain low at 2 all week. A coronal hole threatens to push the Kp index higher, perhaps late today, the 21st, or tomorrow, the 22nd.
 
And now the VHF and up propagation news from G3YLA and G4BAO
The first part of the coming week will be under the influence of the unsettled weather pattern with lows and fronts affecting the British Isles. So, it feels like there will be a few more days for the GHz rain scatter folk to play.
Be aware that even among low-pressure systems there can be fleeting moments of good Tropo. On Friday the 19th there were ideal Tropo conditions over southern Britain and south across Biscay to Spain as well as east across the North Sea.
The big change takes place on Wednesday as an area of high pressure starts to build over the UK. This could last through to the end of the week. So, there is plenty of time to develop some good Tropo conditions over large parts of the UK and near-continent.
There will probably be an elevated inversion some 1 or 2km above the surface. This will be caused by the high itself and may provide ducting conditions throughout the 24-hour period. This may be supported by temporary surface inversions overnight due to the ground cooling.
These features tend to take a while to establish, which suggests that the latter part of the coming week may be the best time to operate. The effect will only just be starting to influence conditions over the western side of the UK for the SHF UK Activity Contest on Tuesday the 23rd.
Regarding the aurora prospects, it feels like we should be keeping a watch throughout this autumn period when the Earth’s magnetic field couples with the solar wind more effectively. Earlier last week the Kp reached 5, which is a good trigger to get interested in beaming north for those fluttery auroral signals.
Meteor scatter remains in between events at the moment with no major showers in the period. So, it’s random meteors only which, as we know, tend to favour the early morning, pre-dawn hours.
We are outside the traditional Sporadic-E season now but, as you may have noticed on the Propquest graphs, there has been the occasional spike on the foEs plot up to 5MHz or so. This is plenty to generate some strong short-skip European signals on the HF bands, especially 10m.
In the morning on Wednesday the 17th, Sporadic-E was probably triggered by the powerful jet stream moving east over the near continent. There may well be further occasions with strong jet streams during the next week, so keep checking the NVIS tab at propquest.co.uk to see if the foEs trace spikes again.
Now for an EME update. Moon declination is decreasing, from its maximum on the 14th of September. The Moon’s distance from Earth is also increasing until apogee on the 27th and 28th of September. This means path losses are growing over the next week. Sky noise will remain low until the 29th and 30th of September.
And that’s all from the propagation team this week.

RCF Trustee, Andy Webster, G7UHN, on inspiring the next generation of radio amateurs
The RSGB LoRa balloon is to be launched this week
Will Richardson, 2E0WYA, has been co-opted to the RSGB Board as Vice Chair
Radio Communications Foundation Trustee, Andy Webster, G7UHN, will be at this year’s RSGB Convention to deliver a fascinating lecture on using radio technology to engage and inspire non-radio amateurs. In particular, he will look at this within Science, Technology, Engineering and Maths education settings, using the subject to connect with young people. Matthew Phillips, G6WPJ, will also be at the Convention, where he will be discussing the use of low-power software-defined radio to rejuvenate medium- and short-wave broadcasting. These are two of nearly 50 speakers who will be delivering engaging and topical presentations for Convention attendees. If this isn’t enough to entice you, visit the Convention web pages via rsgb.org/convention, where you’ll find details on workshops, a drop-in session on the UK Meteor Beacon Project, and information on the AMSAT-UK Colloquium. In addition to the usual GB3HQ operation that will run throughout the event, at this year’s Convention, a special 145 Alive net will be hosted by GB3HQ from 12 pm to 3 pm on the Saturday. You will be able to join the net or simply check in on the day and all callers will be recorded in the log. The Convention takes place at Kents Hill Conference Centre between the 10th and 12th of October.
Only a few days remain until the RSGB LoRa balloon is launched. If you haven’t already heard about the event, you still have time to take part. Go to rsgb.org/lora-balloon  and download a detailed guide to help you build and code your LoRa tracker board. You can also find a link to a video in which Fraser, MM0EFI, demonstrates the process. The balloon launch takes place on Saturday, the 20th of September, at approximately 11 am BST. The challenge is open to all radio amateurs, but to be eligible to win one of the two available prizes, you must be an RSGB individual member or an affiliated club.
The RSGB Board is pleased to announce that it is co-opting Will Richardson, 2E0WYA to the Board to serve until the 2026 RSGB AGM. He will also serve as the Board Vice Chair. Will has significant senior management skills and experience and will be a great asset in helping the Board move forward with the RSGB strategy.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 11th of September
As of Thursday, the 11th of September, it looked like someone had thrown a switch on the Sun to turn off all new sunspots! Unless there is a big change, there will be no sunspots visible on the Sun’s surface today, the 14th.
It is clear we are no longer at solar maximum.
A bigger problem is a large coronal hole on the Sun’s surface, which is rotating to be Earth facing. It is on the Sun’s equator, so it is ideally placed for maximum disruption to the Earth. A high-speed solar wind stream should reach Earth by the 14th of September, and geomagnetic storming may be possible at higher latitudes. Expect maximum usable frequencies, or MUFs, to drop and trans-polar paths to be affected once the Kp index rises.
HF is now starting to improve as we head towards mid-September. By 1000UTC, Propquest shows that the MUF over a 3,000km path can be as high as 31MHz, as long as the Kp index stays low. This should continue to improve as we head into October.
The best DX last week continued to be T30TTT in Western Kiribati, this time on the 40 and 17m bands using FT8. 9J2FI in Zambia also put in an appearance on the 17m band using FT8. TZ4AM in Mali was spotted on the 15m band using SSB. For Morse enthusiasts, HC5AI in Ecuador was working on the 15m band using CW, according to the CDXC Slack chat group.
NOAA predicts that the solar flux index will start the coming week at 125 but then gradually improve to reach 145 by the end of the week. As mentioned earlier, the Kp index is set to reach 4 or 5 between the 14th and 16th of September due to the coronal hole.
And now the VHF and up propagation news from G3YLA and G4BAO
The present spell of unsettled weather is likely to remain the main driver of weather-related propagation modes for the next week. Low-pressure systems are following the jet stream across the Atlantic and over the UK, which is a typical track for this time of the year. This means that we should expect to experience the odd example of rain scatter for the GHz operators, and occasional strong winds will start to test that we have our antennas in good order after the quieter weather during the summer.
This is not to say that there won’t be any Tropo, but we will have to look for it carefully. In a mobile weather pattern such as this, the periods of high pressure tend to act as separators between the lows and, as a result, they usually move with similar speed. This makes them short-lived and thus not particularly good at establishing strong inversions for Tropo. There are two low-grade possibilities. One is around Tuesday the 16th as a weak transient ridge moves across the country. The second will be as another weak ridge moves across on Friday, the 19th.
The meteor scatter situation is still pretty much in a random activity state, although there was a minor shower of the Epsilon Perseids, which peaked on the 9th and may have a few left in the tail-off. However, in general, it's more realistic to assume we’re dealing with random activity. Aurora, on the other hand, has been putting in an appearance lately, so keep watching the Kp index for values climbing above 5.
Now for an update on EME. Today, the 14th, marks the Moon’s maximum declination – its highest point in the sky. Perigee, when the Moon is at its closest point to Earth, was passed on September the 9th, so path losses are increasing. Sky noise is low and will remain so until the 20th to 22nd, when the new Moon is very close to the Sun.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 3rd of September
Last week’s aurora may have come as a bit of a surprise! The propagation segment for GB2RS is usually written on a Thursday, but the aurora was sparked by a solar flare that took place two days later, at 2002 UTC on the 30th of August.
As we don’t have a crystal ball, we couldn’t have predicted it!
The Kp index hit 3 late on the 1st of September, with aurora visible over much of the UK. HF propagation was affected with sudden swings in the maximum usable frequency over most of the day on Tuesday, the 2nd of September.
At the time of writing, a geomagnetic storm watch remains in effect with the solar wind speed above 500 kilometres per second. September is a good month for aurora due to the Russell-McPherron effect, when the Earth’s axis aligns perpendicularly to the Sun-Earth line during the equinox. This creates ideal conditions for a reconnection between the solar wind and Earth’s magnetic field. So, keep an eye on solarham.com for daily updates.
The Sun remains active with plenty of sunspots. The solar flux index stood at 187 on Wednesday, the 3rd, down from 202 the day before.
HF propagation remains good, out of the auroral periods, and as we progress into September, it should improve even more. Some of the best DX this week included VK2/SP9FIH on Lord Howe Island using the Superfox FT8 mode, and T30TTT on Western Kiribati using both CW and FT8. Other choice DX included 3C3W in Equatorial Guinea on FT8, TJ1GD in Cameroon on 20m CW, and 5H8HZ in Tanzania on 30m FT8.
Next week, NOAA predicts the solar flux index will decline to 160, and then perhaps 125. Unsettled geomagnetic conditions are forecast until the 10th, with a maximum Kp index of 4 predicted. This may be due to a large elongated coronal hole on the Sun’s surface, which became Earth-facing on Wednesday, the 3rd.
And now the VHF and up propagation news from G3YLA and G4BAO
Rain and sequences of low pressure will drive the weather agenda for much of the coming week.
The only reasonable chance of Tropo appears to be Friday and Saturday with high pressure to the southeast and support for paths to the continent and across the North Sea. It is worth noting that, in general, short-lived highs like this one do not have the necessary time to generate a strong, elevated inversion before declining. So don’t expect too much.
Rain scatter, on the other hand, is much more likely to be worth considering for the gigahertz stations next week, with plenty of rain events coming along.
The Sporadic-E season daily blogs have now finished for this year, but you may still find it worthwhile looking at the Dourbes graph at propquest.co.uk. You will notice the odd blip on the foEs trace, so keep it in mind for the 10 and 6m bands – at least for the next week.
Meteor scatter is still in random territory for this period. We are between the Perseids in mid-August and the Draconids, which peak on the 8th of October. This means that the pre-dawn morning hours will be good times to try.
There were some auroral signals during the 2m UK Activity Contest on Tuesday, the 2nd. We are coming into the autumn season when conditions tend to be more favourable for aurora.
The message is, of course, to monitor the Kp index for values rising above 4 or 5. Remember, these three-hourly planetary readings can smooth out shorter-duration peaks, so maybe don’t wait for it to get to the dizzy heights of 6 or 7 before taking an interest.
Moon declination is still negative, not going positive until Monday, the 8th. So, Moon window lengths and peak elevation will continue to increase. Path losses are still falling until perigee on Wednesday, the 10th. 144MHz sky noise is low all week.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 28th of August 2025
This week saw a change in HF propagation with a perceptible move towards more autumnal conditions.
The 10 and 12m bands have started opening up to the USA, at least on FT8. As we move into September, this will improve further. Also, as we head towards the Autumnal Equinox, we can expect better conditions on north-south paths, such as the UK to South Africa.
The week saw the solar flux index climb to 226 on Thursday, the 28th, thanks to a host of sunspots, mainly in the Sun’s southern hemisphere.
Over the last seven days, the Sun also provided us with 12 M-class solar flares. Any associated coronal mass ejections, or CMEs, were not Earth-directed, so these had little effect, and the Kp index stayed firmly at 3 or below. The latest updates suggest that there is only a ten per cent chance of a strong X-class solar flare.
FT8 continues to be the preferred HF mode, or so it seems, with stations in China, Japan, Indonesia and Cameroon making their way into UK logs on the 12m band.
The 10m band has also been humming with South America rolling in during late afternoon and early evening. This can only get better as we move into September and October.
NOAA predicts that the coming week will start with a solar flux index of 155 tomorrow, the 1st. This may be a little pessimistic, but we’ll see. It also predicts that the solar flux index will drop off as the week progresses, ending the week at 125.
Geomagnetic conditions are forecast to be good for the first half of the week, but then decline from the 4th of September. Batten down the hatches as a Kp index of 6 is forecast for the 5th, with unsettled conditions lasting until the 10th of September. Check for auroral HF signals on the 5th, or even the possibility of visible aurora from the UK.
We recommend you get your HF DXing in early next week!
And now the VHF and up propagation news from G3YLA and G4BAO
Last week saw some lovely late-season Sporadic-E on the 6 and 4m bands, including Spain, Italy, and east into Ukraine. There was an opening to Brazil on the 24th that reached as far as East Anglia, but, as usual, stations on the south coast and west of the country had the best of the transatlantic QSOs.  
This is the last bulletin in the nominal 2025 Sporadic-E season, which lasts from May to August. However, last week was a good reminder not to give up too soon, as there were several CW and SSB paths showing up, particularly on the 10 and 6m bands. There were also a few reports on the 4m band.
The daily Sporadic-E blogs on propquest.co.uk  come to an end today, the 31st, but the site will continue to provide the maps as usual. To help you, notes on how to interpret the maps are available on the website. Thanks to all the Sporadic-E operators who have submitted logs to the various clusters this year.
The change over to unsettled weather is now complete, and we will see rain and thunderstorms in most areas from time to time. It’s a good period to check out rain scatter propagation if you are set up for the gigahertz bands.
The heavier rain is well-captured by the many online rain radar displays to help you track the most active scattering volumes, which move with the stronger winds quite high up in the atmosphere. Speeds of 30 to 60 miles per hour are common.
There is one note of contrast with the model evolution after midweek. One branch sticks with low pressure to the following weekend, while another outcome tries to bring in a ridge of high pressure and a chance of Tropo propagation. If the latter turns out to be the actual evolution, it may prove useful for the 144MHz Trophy and Backpackers Contest next weekend. However, it may not have arrived in time for the 144MHz UK Activity Contest on Tuesday.
The solar conditions are still providing some interest for auroral propagation, but with a Kp index less than 3, nothing of use radio-wise. Look for a Kp index increase beyond 7 for that. Meteor activity is currently between major showers, so expect random activity, which suggests early mornings for checking out meteor scatter prospects.
Moon declination is negative, reaching a minimum on Monda,y the 1st. So, it’s a week to check out your equipment rather than to operate. With the Sun still high in the sky, it’s easy to check system performance with Sun noise. Path losses started to fall after apogee on Friday the 29th. 144MHz sky noise is close to 3,000 Kelvin on Monday, dropping back to moderate on Wednesday.
And that’s all from the propagation team this week.

The World Wide Digi DX Contest starts at 1200UTC on Saturday the 30th and ends at 1200UTC on Sunday the 31st of August. Using FT4 and FT8 on the 160 to 10m bands, where contests are permitted, the exchange is your four-character locator.
Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 21st of August
Last week was relatively good from an HF propagation standpoint, with only a few periods with an elevated Kp index thanks to a high-speed solar wind stream from a coronal hole.
The Kp index hit 4.67 on the 19th of August and 4 again on the 20th due to the solar wind hitting earth at more than 600 kilometres per second. Luckily, the interplanetary magnetic field remained mostly neutral, or north-facing, and the density was low, saving us from more disruption.
Meanwhile, the solar flux index declined to 120 by Thursday the 21st. This is still high enough to affect the ionosphere, but well down on recent highs in the 140s and 150s.
The daytime critical frequency has mostly remained above 7.5MHz, meaning the 40m band has managed to remain good for inter-UK contacts. This has also meant that maximum usable frequencies, or MUFs, over a 3,000km path hit 21MHz and even 24.9MHz at times. Nighttime critical frequencies have been around 5MHz, giving an MUF over 3,000km of below 14MHz and sometimes even as low as 10MHz.
It may be another month or so before we see daytime F2-layer openings starting again on 28MHz. In the meantime, focus your efforts during daylight on 21MHz and below.
T30TTT in Western Kiribati remains one of the DX stations to chase, mostly on 18 and 21MHz. The operators are alternating between using CW, SSB and FT8. Other choice DX worked included Jim, E51JD on South Cook Islands who has been active on the 17m band using SSB. TY5AD in Benin, Africa has been worked on the 10m band using FT8. And 3G1P, an IOTA DXpedition in Chile, was logged on the 15m band using SSB.
Closer to home, today, the 24th, is the last chance to work OG0C on the Aland Islands.
Next week, NOAA predicts that the solar flux index will remain in the 120s, until the end of the month when it could rise to 130 and even 150. Unsettled geomagnetic conditions are forecast for the 28th of August when the Kp index could hit 4.
Otherwise, make the most of the relatively settled conditions over the first half of next week to work some choice DX!
And now the VHF and up propagation news from G3YLA and G4BAO
After this weekend, the weather changes from a Tropo high pressure pattern to an unsettled story with areas of low pressure and fronts together with wind and rain. This will remove any Tropo options and replace them with a possibility of rain scatter on the GHz bands.
The auroral conditions have recently produced minor enhancements, although nothing too exciting so far radio-wise. It’s worth noting that the autumn, along with spring, are times of the year when auroras are more likely. So, it’s a good time of the year to keep abreast of the Kp index, especially if the Kp index goes above 5.
We are at the tail end of the broader period of the Perseid meteor shower, ending today, the 24th. This leaves random meteor activity as the only option for a while. As those of you who are active in the mode already know, it tends to favour the early pre-dawn period for better chances of catching meteor scatter.
Sporadic-E is hanging on for the last week or two of the 2025 season, but opportunities become much rarer. You’ll need to keep a close watch on band reports to capture these increasingly fleeting events. In the main Sporadic-E season, there are usually two well-defined peaks of activity in the morning and late afternoon. However, in the tail of the Sporadic-E season you are just as likely to find it around the middle of the day as at any other time.
The daily Sporadic-E blogs at propquest.co.uk  finish at the end of August, but in some years the last events have extended into the first week of September. 
Moon declination is still positive, but falling, going negative on Monday. So, Moon window lengths and peak elevation will follow suit. Path losses are rising again as we approach apogee on Friday the 29th. 144MHz sky noise was low until lunchtime on Friday the 22nd, when the Sun and the Moon were very close in the sky. This continued throughout the Moon window on yesterday, the 23rd, and will revert to moderate-to-low next week. 
And that’s all from the propagation team this week.

National Coding Week takes place during the third week of September, and the RSGB is dedicating the whole of the month to amateur radio and coding activities. This year, the Society has created two new activities for you to try. Both build on worksheets it shared in previous years; however, you don’t have to have done those first. The Python Pocket Morse activity has been developed by the RSGB Maker Champion Tom Wardill, 2E0JJI and is a low-cost opportunity to learn some Morse and programming together. The exercise will cover using a BBC Micro:bit V2 and the ‘more advanced’ Python programming instead of the previous block programming mode. It is intended as a gentle introduction to both Python and small computer programming and can be done without any previous knowledge of the micro:bit. You can download the full instructions by going to rsgb.org/coding  and selecting ‘Python Pocket Morse’ from the right-hand menu. The other new activity is the LoRa balloon challenge. As well as the manual, which guides you through the process of building your own LoRa tracker and seeing how far your signal can reach, the Society has released a video in which Fraser, MM0EFI, demonstrates the process. Find both on the RSGB website at rsgb.org/lora-balloon

On Sunday the 24th, the UK Microwave Group 5.7 and 10GHz Contest runs from 0600 to 1800 UTC. Using all modes on 5.7 and 10GHz frequencies, the exchange is signal report, serial number and locator.
Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 14th of August
Last weekend was characterised by unsettled geomagnetic conditions caused by a massive coronal hole on the Sun.
At one point, the Kp index got up to 6, with a corresponding decrease in maximum usable frequencies, or MUFs. The Dourbes Digisonde failed to record much at all over six hours. Luckily, that disruption had passed by Monday the 11th as the ionosphere started to get back to normal.
Meanwhile, the solar flux index reached a peak of 153 on the 10th, before dropping back to 140 on Thursday, the 14th. There have been numerous C-class solar flares and ten M-class events over the past five days, but nothing of note.
The MUF over a 3,000km path exceeded 24.9MHz at times, but has generally been between 21 and 24MHz.
Another coronal hole is Earth-centric at the moment and could cause some disruption, with increased Kp indices by tomorrow, the 18th or Tuesday the 19th.
HF DX has been good at times, with the stand-out station being T30TTT in Western Kiribati. The station has been worked on many bands, including 20, 15 and 10m using CW, as well as FT4 and FT8. After two weeks, there will be just one operator who is there until mid-September. So you have plenty of time to work him.
Stanley, AH6KO, in Hawaii, has also been spotted on the 15m band using CW. This is a relatively rare opportunity and good for anyone chasing their Worked All States award.
A little closer to home is Henri, OJ0JR on Market Reef, who has been easily workable on the 30m band using FT8. Get in quick, though, as he is only there until tomorrow, the 18th.
Next week, NOAA predicts that the solar flux index will remain in the 140 to 150 range. Unsettled geomagnetic conditions are forecast for tomorrow, the 18th, until Wednesday the 20th, probably caused by the coronal hole mentioned earlier. Better conditions are predicted for the 23rd to the 27th with a maximum Kp index of 3.
And now the VHF and up propagation news from G3YLA and G4BAO
Last week’s propagation highlights were SSB and CW QSOs between the UK and Las Canarias on both the 23 and 13cm bands between G4GLT, EA8DMF, ED8BRZ and EB8AYA. 
There may be more Tropo next week with high pressure close to, or over, the British Isles. However, at this time of the year, any Tropo will be due to temperature inversions. These can be at the surface and are especially persistent over water, so look for marine paths across the North Sea or up the east coast to Scotland.
Other potentially good marine paths might be across the Channel or Biscay to Spain and beyond. The hot days of high summer break down these surface inversions over the land during the day so, if your station is inland, your best chances of Tropo in summer will often be overnight and until mid-morning.
Inversions can also be elevated in the region of the high pressure, say between 1 and 2km above ground, giving good DX prospects that are not affected by the heating of the summer day. In this high-pressure period, it is much more likely to be a surface inversion that drives the Tropo.
There will be little rain in prospect except for parts of Ireland, South Wales and southwest England, where a few thundery showers are possible. However, these will not be particularly good for rain scatter.
There continue to be some aurora alerts, so monitor the Kp index and if it is rising to, say, 6, try beaming north on the 10, 6, 4 and 2m bands in turn to see if any genuine auroral signals are coming back.
Lastly, the Sporadic-E season is coming into its closing weeks. 10m is a good band to check first. If Sporadic-E is very short-skip there, try moving up to 6m or beyond for a strong event. Digital modes are best, so use these to get clues as to where the CW and SSB paths might show up next.
Meteor scatter operators have been very busy during the Perseids meteor shower. The Perseids should still provide some activity in the coming week.
Moon declination is positive and rising until Tuesday the 19th, so Moon window lengths and peak elevation will follow suit. Path losses are rising again as we are now past perigee. 144MHz sky noise is low to moderate all next week.
And that’s all from the propagation team this week.

The news headlines:
Three fantastic workshops have been announced for the RSGB Convention
The RSGB National Radio Centre has won a prestigious award
Ensure that Ofcom has your correct contact details
Discover new skills at this year’s RSGB Convention in October by securing your place in one, or all three, of the workshops that will be taking place. On Friday, the 10th of October, the RSGB is giving you the opportunity to build on the basics of Arduino programming with a six-hour workshop that will cover programming Direct Digital Synthesis for RF generation. This session will also include how to use generative AI tools such as ChatGPT to write software. You are welcome to book this workshop even if you’re not able to attend the whole Convention this year. If programming is new to you, then Saturday’s two-hour workshop is a great place to get started. This session will introduce you to microcontroller unit programming through a short presentation followed by practical exercises. Alternatively, on Sunday, you can book into a two-hour antenna building workshop that will guide you through the process of constructing a 49:1 balun for use in a QRP end-fed long-wire antenna.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 7th of August
Over the last week, we had nearly ideal solar conditions for HF propagation. These included low geomagnetic indices and a reasonable solar flux index, hovering around the 150 mark.
Other solar events of note included six M-class solar flares.
The only stumbling block is the time of year, with summer seeing lower maximum usable frequencies, or MUFs, and poorer propagation due to changes in ionospheric chemistry. We will have to wait another month or so to see conditions pick up.
The main HF DX this week has been T30TTT from Western Kiribati, mainly on FT8 and CW and focusing on the 20 and 17m bands. TJ1GD from Cameroon was worked on the 17m band using FT8. E51KEE on the South Cook Islands was logged on the 17 and 15m bands using CW. And finally, AH6KO in Hawaii was worked on the 15m band using CW.
But this may all be set to change.
A coronal mass ejection observed on Tuesday, the 5th, may deliver a glancing blow to the Earth's geomagnetic field. This may also coincide with an expected high-speed stream from a very large coronal hole on the Sun’s surface. NOAA predicts that the Kp index could rise to 5 or 6.
The hole is so large and elongated that we could see unsettled conditions occurring in the coming week.
NOAA predicts unsettled geomagnetic conditions from the 11th to the 14th of August. It also predicts more unsettled conditions from the 18th to the 22nd, with a maximum Kp index of 5. Expect reduced MUFs and poor HF conditions, especially for paths over the poles.
And now the VHF and up propagation news from G3YLA and G4BAO
The main setting for the weather pattern over the next week is a tendency for high pressure in the south and lower pressure to the north of Britain. There may be some input from a low over France around the middle of the week. This might introduce some thundery showers and a chance of rain scatter on the GHz bands.
Meanwhile, occasional weak frontal systems will bring patchy rain to the far northwest, but probably not so good for rain scatter opportunities.
The Tropo at this time of year can be very good around the coasts and occasionally inland overnight. However, it tends to weaken inland during the heating of the day. Out at sea, temperatures remain fairly constant and maintain an ideal cool, moist layer at the sea surface overlain by a layer of warm, dry air from the land. This provides Tropo 24 hours a day, seven days a week.
Mid-August is good for meteor scatter with the peak of the Perseids on the Tuesday night of the 12th and 13th. Apart from digital-mode QSOs, it’s good for late summer evening sky watching. It is fascinating to listen to the VHF SSB meteor scatter frequencies while watching to get the full experience. It’s a broad shower, so don’t worry if you must pick a night either side of the peak.
The chances of an aurora are not zero, with further minor alerts to remind us that it's worth checking. The main mode for DX is probably still going to be Sporadic-E, which has roughly another four weeks to run. Don’t expect something every day, as it tends to become more random towards the latter part of the season.
Moon declination is negative, but rising again, so Moon window lengths and peak elevation will increase. Path losses are also falling, reaching a minimum at perigee on Thursday, the 14th of August. 144MHz sky noise is low to moderate all next week.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 31st of July 2025
Last week was very much a repeat performance of the week before. We had relatively calm geomagnetic conditions and few solar flares to contend with. The only flares were minor C-class events.
The Kp index never got above 3, and the solar flux index was in the 140s to 150s.
The F2-layer maximum usable frequency over a 3,000km path rose to 21MHz but didn’t get much higher, which is normal for the summer period.
A team from Norfolk Amateur Radio Club was active as GM0FRT/P from the Shetland Islands for the IOTA contest. They were workable from JO02NN on 14 and 21MHz for much of the contest period. The distance to Shetland from central UK is about 887km, or 551 miles. Given the distance involved, the 21MHz openings were probably Sporadic-E, but they were loud for hours on end.
Other DX worked last week included T30TTT from Western Kiribati on the 10m band using FT8 over the North Pole. 9M8A from East Malaysia was also on the 10m band using FT8. XW4KV from Laos was on the 12m band operating FT8. 3B9SP on Rodriguez Island put in an appearance on the 17 and 12m bands using FT8. The station was also worked using CW on the 40, 30, 20 and 15m bands.
That’s not a bad haul for summer DX and if the Kp index can stay low, we could get similar next week.
Speaking of which, NOAA predicts that the solar flux index will be in the range of 150 to 160 next week. Unsettled geomagnetic conditions are forecast for the period of the 7th to the 14th of August, with a maximum predicted Kp index of 5.
And finally, there is talk of a possible large sunspot group on the far side of the Sun.
The region in question belongs to a cluster of spots, including AR 4136, 4139 and 4143, last seen earlier this month. Solar rotation will carry what remains of these regions back into view next week. So, keep an eye on solarham.com  for up-to-date details.
And now the VHF and up propagation news from G3YLA and G4BAO
The slightly unsettled theme to the weather will remain into next week, although there are signs that high pressure will try to return in the middle of the week for a time.
Models disagree on details, with some bringing another thundery low into the south later. This means that there will be some Tropo at times and, in high summer, this tends to be generally strongest around the coasts. To benefit from these conditions inland it’s better to wait for night cooling.
As usual with thundery weather, it’s a good chance to listen for rain scatter on the GHz bands. Another mode that still deserves attention is meteor scatter. Look out for the early stirrings of the August Perseids, which peak around the 12th and 13th of the month. 
Surprisingly, Aurora is staying in the limelight. Periodic alerts are suggesting it's worth turning your VHF beams north if you notice any signs of fluttery HF signals or discover the Kp index has risen to 5 or above. If auroral activity appears on the 10 or 6m bands, then check the higher bands as the event develops.
Sporadic-E is now in its occasional phase as we move into August. It is less common than in June, but still worth considering. Check the usual cluster maps and Propquest to see how the day is unfolding.
Moon declination is negative, falling to a minimum on Tuesday, the 5th. So, Moon windows and peak elevation will also decline. Path losses reached maximum at apogee on the 1st of August, so are starting to fall again. 144MHz sky noise starts the coming week moderately, but will rise to high levels by Monday. It will reach over 300 Kelvin by Tuesday evening before falling back.
And that’s all from the propagation team this week.

National Coding Week takes place in the third week of September, and the RSGB is once again dedicating a whole month to amateur radio and coding activities. As part of the Society’s strategy to encourage practical skills development, it is inviting you to take part in its LoRa high-altitude balloon challenge. The project has been developed by the RSGB Outreach team and takes place on Saturday, the 20th of September. The balloon will be equipped with a LoRa digipeater, and your challenge is to follow the instructions provided and build a LoRa tracker. If your tracker build is successful, it will beam up packets to the airborne relay, which will transmit them to a local i-gate. Your goal is to get your signal the furthest distance from the launch. Anyone can enter, but to win one of the prizes, you need to be an RSGB member. Get involved as a single operator or as a team in your RSGB-affiliated club. The RSGB is delighted that Moonraker is sponsoring this event and will award a £200 Moonraker voucher to the winner of each category. Find out how to get involved with this exciting LoRa event by going to rsgb.org/lora-balloon
The RSGB is proud to announce the release of a new high-contrast logbook designed to support amateur radio operators with visual impairments or learning difficulties. Responding to feedback from members and accessibility advocates, the RSGB developed the logbook with wider spacing and a high-contrast black-and-yellow design to improve ease of use. This release reflects the RSGB’s wider commitment to improving accessibility across all areas of the Society and amateur radio as a whole. The organisation continues to explore ways to make the hobby more inclusive and user-friendly for all participants. This version will be available through Amazon and is expected to be a useful addition for both seasoned operators and newcomers looking for a more accessible logging option. As part of its long-term vision, the RSGB is looking to recruit a dedicated team to assess and enhance accessibility throughout the Society and help shape a more inclusive future for amateur radio. If you’re interested in contributing to this important initiative, please email RSGB Board Director Nathan Nuttall, 2M0OCC, via 2m0occ@rsgb.org.uk
Since the launch of its DMR project in May, the RSGB Outreach team is delighted that four schools and one homeschool have signed up. The project aims to help young people get on the air and build their confidence in making QSOs. Each of the successful applicants will be loaned a TYT DMR handheld radio and a Pi-Star-based hotspot. The RSGB Youth Chair and Youth Champion for Schools, Chris Aitken, MM0WIC, is supporting two new school amateur radio clubs that have chosen this as an entry-level activity for their club members. DMR is particularly useful in a school club scenario where antenna placement is a challenge and can be easily deployed, giving young people access to the world. During the summer holidays, the DMR handsets will be used at the West Sussex International Jamboree with Regional Representative 10, Simon Harris, G4WQG, attending the event and Wick High School Radio Club member Jacob, MM7IFL, supporting remotely via DMR. Listen out for further updates after the summer when the RSGB plans to get a youth net operational on Brandmeister Talk Group 23554. The net aims to encourage young operators to get on the air and become comfortable with QSO structure and general rag-chewing. If you want to start a school club or are interested in being part of the DMR project, email Chris via youthchampion.school@rsgb.org.uk
The prospect of a USA constellation of 240 commercial satellites that would use 430 to 440MHz for wideband control and telemetry has prompted an unprecedented response from the amateur radio community to a Federal Communications Commission, or FCC, consultation. FCC Proceeding 25-201 would see AST SpaceMobile utilise much of 430 to 440MHz for downlinks, as well as a series of ground stations around the world. The RSGB and several other IARU member societies, along with the ARRL and over 2,000 individuals, have submitted comments to this consultation. The IARU itself has also issued a statement on the matter. Links for this, including the RSGB response, can be found on the RSGB website. Go to rsgb.org/spectrumforum and then choose the ‘Papers and consultations’ option in the right-hand menu. Following the main submission deadline of the 21st of July, the FCC process has further phases to go through.

On Saturday, the 2nd, the 144MHz Low Power Contest runs from 1400 to 1800UTC. Using all modes on the 2m band, the exchange is signal report, serial number and locator.
On Sunday, the 3rd, the 432MHz Low Power Contest runs from 0800 to 1200UTC. Using all modes on the 70cm band, the exchange is signal report, serial number, locator and two-letter postcode.
The UK Six Metre Group Summer Marathon started on Saturday, the 3rd of May and ends on Sunday, the 3rd of August. Using all modes on the 6m band, the exchange is your four-character locator.
Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 24th of July
It was a bit of a mixed bag last week. The first half saw settled geomagnetic conditions, but from the 22nd of July, we had a disturbance thanks to output from a solar coronal hole.
This saw the Kp index rise to 4.67 and ultimately 5. The stream from the Sun reached around 730 kilometres per second, while the Bz component of the interplanetary magnetic field, or IMF, was mostly neutral with a few brief periods when it pointed slightly south.
So, its effects were perhaps not as bad as they could have been. The coronal hole has now rotated out of view, so we may have some better days. Meanwhile, the solar flux index has been in the range of 140 to 150, which is pretty good.
There were no M-class or higher solar flares over the past week, which is unusual.
So overall, HF propagation was humming, at least until the Kp index hit 5.
Maximum useable frequencies, or MUFs, over a 3,000km path during daylight continue to be around 21MHz, but often dip to 18MHz at times. Nighttime conditions can be variable. If the 14MHz band isn’t open for you, try 10MHz.
Earlier in the week, some daytime tests with WSPR on the 20m band saw stations logged from Australia and the far west of Canada. DP0POL, the Polarstern research vessel doing work in the Artic, was also logged.
Next week, NOAA predicts that the solar flux index may decline slightly to be in the range of 130 to 135. Geomagnetic conditions are predicted to be settled until the 1st of August, when the Kp index could rise to 4. This period of unsettled conditions, with reduced MUFs, could last until the 4th of August.
And now the VHF and up propagation news from G3YLA and G4BAO
We will see the return of a weak ridge of high pressure today. This will last until the middle of the coming week.
The second half of the week will be a little more unsettled with some occasional spells of rain. This suggests that some Tropo is possible, before a gradual swap over to rain scatter. However, high pressure near the Azores may still influence the western side of Britain.
This week will see the peak of two meteor showers, the Alpha Capricornids and Delta Aquariids. These are worth checking out, if only to get your practice time in before one of the major showers of the year – the Perseids on the 12th and 13th of August.
Barely a day passes without some auroral alert, and this can be an exciting mode. Several good indicators are available, such as when the Kp index is above 5, or watery-sounding signals on the 40 and 20m bands. If you hear these, try looking north on the 6, 4 or 2m bands.
Sporadic-E continues to be mentioned on the clusters somewhere in Europe on most days. But remember that it’s a very localised mode and is rarely available for everyone at the same time.
The best way to track it down is to use the clusters and a good list of beacons, to see who your ‘locals’ are working on FT8. It's a very hit-and-miss mode. Meteor activity is a good indicator, whereas a high Kp index is a bad one. Whether it happens is often a balance between many opposing components. So, even a potentially good day may not be good where you are.
The good news is that the last openings of the summer can occur into the first week of September.
Moon declination is still positive but going negative again on Tuesday, the 29th. Moon windows and peak elevation will reduce. Path losses are rising now as we are past perigee. 144MHz sky noise starts the coming week low but will rise to moderate by the weekend.
And that’s all from the propagation team this week.
