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.

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.

Ian also played a pivotal role in establishing the RSGB School Links Project, which introduced classroom activities that connect amateur radio with the school curricula. The project was established following Tim Peake’s Principia mission to the International Space Station, which included ten UK ARISS school contacts during Tim’s time in space. In his new RSGB role, Ian is enthusiastic about fostering close ties with STEM organisations and STEM ambassadors across the UK, including those already engaged with the RSGB. If you’d like to contact Ian to share suggestions that may enhance the RSGB’s STEM outreach programme, you can contact him via stem.champion@rsgb.org.uk
If you are looking for an activity to keep the children busy during the summer holidays, why not plan a visit to the RSGB National Radio Centre at Bletchley Park? The knowledgeable and welcoming volunteers will be on hand to give an introduction to radio technology, how it works and why it is still relevant today. There are interactive displays as well as the opportunity to get a certificate for sending your name in Morse code. There will also be three more of the successful Spy Transmitter events during the summer, so keep an eye on the Bletchley Park website and the RSGB comms channels if you’d like to take part. Start planning your visit by going to rsgb.org/nrc. Don’t forget that as a membership benefit, RSGB members can visit the world-famous Bletchley Park estate, including the RSGB National Radio Centre, for free. Download your voucher by going to rsgb.org/bpvoucher
Did you know that the Radio Communications Foundation offers funding to young people who need help with the Foundation licence exam fee? They need to be under the age of 21 and in full-time education. If you know someone who may be eligible, help spread the word and promote this programme. To find out more and submit an application, go to commsfoundation.co.uk  and select ‘RCF Grants’ from the sub-menu.
This year marked the centenary of the unique mechanical Alexanderson Alternator transmitter at Grimeton near Varberg in Sweden. GB2RS Newsreader and NRC volunteer Brian Hardy, G4BIP, travelled to Sweden for a special 70th birthday trip with his partner Hilary, G7SOI. On the 2nd of July, they were able to watch SAQ being operated on a frequency of 17.2kHz as part of the celebration. Brian was even allowed to key up the station in advance of the formal transmission and send some test messages. Despite SAQ having a power output of 80kW, nobody came back to his CQ call! However, it was a big tick on his 'bucket list'! The station is usually fired up twice a year and is well worth a visit. You can discover much more, including a fascinating YouTube video of the centenary event, via alexander.n.se
The UK Six Metre Group’s AGM will be held via Zoom on Sunday, the 27th of July 2025 at 17:00 UTC. The AGM will include receiving the Group’s financial report, presentation of officers’ reports and elections. For more information about the Group, visit uksmg.org

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 17th of July.
Space weather has been a bit like our terrestrial weather this week. We have had sunspots, some C-class solar flares, some coronal mass ejections and a large coronal hole – unsettled, you could say!
Luckily, the coronal mass ejections were not Earth-directed, but the Kp index did rise to 5 on the 15th of July and again late on the 16th of July. The large coronal hole, which may have been responsible, is well south on the Sun’s surface and should rotate out of Earth’s view by the beginning of the coming week.
Meanwhile, the Sun appears to have woken up, spot-wise, with 11 groups on the 17th of July, four of which are classed as growing, while two are stable and three are declining. Two groups are unclassified at this time.
This resulted in an increase in the solar flux index to 152 on Thursday, the 17th.
Overall, this means quite reasonable HF conditions considering the time of year. Recent DX spots included the JW0V DXpedition to Svalbard on both SSB and FT8, and C93RRC in Mozambique on 17m CW, plus 30, 20 and 10m FT8.
Conditions have been up and down, with daytime maximum usable frequencies, or MUFs, over a 3,000km path reaching 28MHz at times, but then quickly declining to 18 or 19MHz ten minutes later. All we can advise is to keep listening!
Nighttime MUFs over a 3,000km path have generally been exceeding 10MHz, and occasionally reaching 14MHz.
We may start to see nighttime 14MHz openings tailing off as we head into late July.
Next week, NOAA is a little pessimistic with a predicted solar flux index in the range of 118 to 130. Unsettled geomagnetic conditions, with a possible Kp of 4, are forecast for Tuesday, 22nd of July.
And now the VHF and up propagation news from G3YLA and G4BAO
The unsettled weather over this weekend will continue through the first part of the coming week. Some of the rain will be heavy and possibly thundery, so there is a good chance of rain scatter on the GHz bands.
After mid-week, the pattern may change enough for a weak ridge of high pressure to build close to the UK and this may offer some Tropo opportunities. It may not be strong enough for it to persist through the warmth of a July day. Thus, most places will have better Tropo prospects overnight.
The solar conditions have recently fired off a steady stream of aurora alerts, and we should probably expect similar in the coming week.
Meteor scatter is often on people’s minds during late summer since we have two showers towards the end of this month and, of course, next month’s Perseids. This month, both the Delta Aquariids and the Alpha Capricornids peak around the 30th of July, but we are already in the broad spread of dates for activity.
Sporadic-E is still happening on most days somewhere within Europe, but even UK stations can expect regular FT8 activity and a fair chance of CW or SSB paths for stronger events.
Last Wednesday saw another early afternoon opening into the USA. These stronger events need a low Kp index, below 3, and some jet stream activity to generate turbulence that can spread upwards to the E region.
In the coming week, we will certainly have some jet stream activity, so it should be worth monitoring your favourite beacons for activity. It’s always helpful to have a list of favourite beacons at the ready to cover a range of directions. For example, one in Finland, Poland, Hungary, Italy and Spain should cover it.
Moon declination is positive again, reaching maximum on Tuesday, the 22nd, with associated long Moon windows and high peak elevation. Path losses continue to fall until perigee today, Sunday, the 20th. 144MHz sky noise is moderate, but Thursday the 24th sees the Moon and Sun close in the sky until early the following day.
And that’s all from the propagation team this week.

The news headlines:
The RSGB announces speakers for its annual Convention in October
Get involved with chasing awards this summer
RSGB Regional Representatives elect a new Regional Forum Chair
The RSGB is delighted to announce that the Keynote Speaker for its 2025 Convention will be Professor Lucie Green. She is a Professor of Physics and a Royal Society University Research Fellow at the Mullard Space Science Laboratory of the University College London. She has also presented many TV and radio programmes, including The Sky at Night and Stargazing Live. During her talk, Professor Green will provide an update on the proposed Moon-Enabled Sun Occultation Mission, which she is working on with fellow UK researchers. The project will enable the team to study the conditions that create solar storms, leading to improvements in forecasts of space weather on Earth. As well as releasing details of the Keynote Speaker, the RSGB has published a teaser of its Convention programme. This includes Neil Smith, G4DBN, who will share his experience of taking complex ideas and turning them into stories that connect with wider audiences. Many of you will be familiar with Neil from the popular BBC series “The Secret Genius of Modern Life”, for which he recreated a device invented by Leon Theremin. Bill Rothwell, G0VDE, will show you that DXpeditions don’t always need to involve masses of equipment, and that one person can make a successful trip with only the luggage they carry. RSGB Propagation Studies Committee member Gwyn Griffiths, G3ZIL, will explore Travelling Ionospheric Disturbances, whilst Brian Coleman, G4NNS, will give you the latest update on the UK Meteor Radar System. Read the full list of confirmed speakers by going to rsgb.org/convention  and selecting the “RSGB 2025 Convention speakers” option from the right-hand menu. The RSGB 2025 Convention is taking place at Kents Hill Conference Centre between the 10th and 12th of October. Book your ticket now and join like-minded people for a fun-filled weekend.
Set yourself a challenge this summer and get involved with awards chasing. The RSGB awards are open to everyone, whatever your age, licence level and personal interests. They encourage you to push yourself further, learn something new and can even help you to make tweaks to your station to maximise performance. If HF is your mode, then visit rsgb.org/awards  and get involved with the IARU Region 1 Award, which encourages you to make contacts with member countries. If VHF or UHF is your preference, then challenge yourself to the 50MHz Continents and Countries Award. Several Foundation awards are aimed at getting new licensees on the air and helping build confidence. For younger RSGB members, there are two awards designed to show the breadth that amateur radio offers. The RSGB Scouts, Cadets and Girlguiding Youth Champion, Samuel McCutchion, 2E1UEL, recently completed the Radio Surfer Award and shared his experience with us. Read how he got on by going to rsgb.org/award-stories 
At a recent meeting of the RSGB Regional Forum, the RSGB Regional Representatives elected George Crawford, MM0JNL, as the Regional Forum Chair. George represents Scotland South and Western Isles as the Representative for Region 1. He got involved in amateur radio in 2020 and gained his Full licence by March 2021. George has also been a GB2RS Newsreader. Along with the rest of the Regional Team, George is keen to continue to help RSGB members and the wider amateur radio community, and to promote amateur radio and the Society at public events. He will be attending Kirriemuir Show on the 19th of July to showcase amateur radio to the agricultural and rural communities. You can hear more details about that in the Special Event News section of this week’s GB2RS News.
Last week, senior RSGB staff and some members of the RSGB Board met for two days to discuss the next implementation phase of the Society’s strategy. The discussions covered several topics, including how to ensure the Society stays relevant to the modern radio amateur. Those discussions led to some initial plans for the next six months that focus on one or two clear goals. More details of the plans will be shared over the coming weeks, including in strategy updates and at the ‘Meet the Board’ session at the RSGB Convention in October. Following the RSGB’s attendance at Dayton and Friedrichshafen, it was also noted that the Society is held in high esteem around the world and that many other national societies are keen to learn from the RSGB’s achievements.
Ben, M7FRS and John, G0JDL, are hoping to be operating aeronautical mobile in a Cessna 172 for about an hour tomorrow, Monday the 14th, over the skies of Norfolk and Suffolk. The pair will be departing from Beccles Airfield at around midday. They will initially be on the 2m band FM calling frequency of 145.500MHz before changing frequency. As per the new licensing arrangements, they will be using less than 500mW. Listen out for them, as they'd love to get you in their log! 
During this weekend’s IARU HF World Championship, five stations will be active on the 80 to 10m bands using SSB and CW and tested under field conditions. They will be using the exact planned equipment for the WRTC 2026 event as a trial. The operating location will be a cluster of sites within the grounds of the Euston Estate in Suffolk. QSL via M0OXO’s OQRS. There will be two awards available for chasers during this event, so listen out for the following callsigns: GB0WR, GB2WR, GB5WR, GB8WR and GB9WR.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 10th of July 2025
Last week was characterised by settled geomagnetic conditions, but a relatively low solar flux index.
The Kp index hit 5.33 on the 6th and 7th of July but was otherwise around 1 or 2 for the rest of the week. These settled conditions were helpful to HF propagation, although the maximum usable frequency over a 3,000km path didn’t get much above 21MHz.
This is likely to be due to the HF summer doldrums, and we are unlikely to see it rise much more until September, once the F2 layer has switched to autumnal propagation conditions.
Meanwhile, the solar flux index remained steadfastly in the range of 115 to 120. This is enough to provide fair propagation, but not enough to set new DX records!
But there was DX to be worked, including T30TT in western Kiribati, on the 20 and 15m bands using the FT8 Fox and Hounds mode. Also, ZD7FT was operating on St Helena Island on the 17m band using SSB, and C94RRC was active on the 10m band from Mozambique using FT8.
Laurie, G3UML on the CDXC Slack group, commented that there was a lot of DX around, including FP/KV1J on the 17m band using SSB on Miquelon Island. Additionally, TY5AD was on the 17m band using CW from Benin. And FY4JI was on the 17m band using SSB from French Guiana.
Now the bad news. A very large solar coronal hole will begin to face Earth this weekend. A solar wind stream flowing from this zone is expected to reach Earth with the main influence occurring today, the 13th, and tomorrow, the 14th.
If the Bz of the plasma cloud points south, we can expect disturbed geomagnetic conditions and a reduction in the maximum usable frequency, or MUF for short.
NOAA predicts unsettled conditions, with a Kp index of 4 between the 15th and 16th of July. The solar flux index is expected to be in the range of 105 to 125 for the next week.
And now the VHF and up propagation news from G3YLA and G4BAO
The hot weather continues to set the agenda in the short term. Something to note is that for VHF and UHF Tropo ducting, the ideal is for warm, dry air to sit on top of cool, moist air.
These conditions are commonplace over the nearby seas as hot, dry air moves out across the coast to overlay the cool, moist air near the sea’s surface. Think of the North Sea, English Channel, Irish Sea and Biscay as being very good Tropo paths in high summer. But the award goes to the Mediterranean, where very strong ducting conditions are pretty much a given if you happen to be sitting on an exotic holiday beach. 
Back at home... if you live inland, then you will be out of luck during the heat of the day since there is no cool, moist surface air. But in the evening, as the ground cools and perhaps cool sea air moves inland, you could find yourself coupled into the Tropo conditions that those on the coast have been enjoying all day.
In other words, for most of the country, Tropo will be better overnight and early morning.
The other modes are worth checking of course, especially Sporadic-E, which is continuing to give some paths on most days, at least for digital modes, but also for those using SSB or CW. 
Most days, there will be some direction available from the UK on the 10m band, and perhaps on the 6m band, with many online clusters to show you where the current paths are located.
We really must get used to the idea that Sporadic-E can be very localised, and you will only know about it if someone calls CQ. If you do that, you may be surprised by how good conditions have been all along!
Disturbed solar conditions should keep aurora as a possibility. Meteor scatter is often worth checking, with two showers peaking later in the month. The middle part of the coming week looks like turning more unsettled for a time, so rain scatter is also an option for the GHz bands.
Moon declination is increasing again, reaching maximum on Tuesday, and path losses are falling. So, it’s time to put the feeder back into the dish. 144MHz sky noise is moderate to start the week but decreasing to low after the weekend.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 3rd of July 2025
It looks like the Space Weather Prediction Centre, which supplies the forecasts for NOAA, were overly cautious last week.
Despite predicting geomagnetic disturbances, we had quite a calm week. The Kp index rose to 3.33 on a few occasions, but that was it. We ended up with settled geomagnetic conditions and a solar flux index in the 120s to 130s. A warning about the impact of a coronal mass ejection, or CME, which left the Sun on the 28th of June, appeared to come to nothing.
This made a much-needed change to the unsettled conditions of previous weeks.
As a result, maximum usable frequencies, or MUFs for short, over a 3,000km path have been above 21MHz at times. At night, MUFs over the same path have been consistently above 14MHz, which is normal for this time of year.
In the summer, we can expect to see nighttime MUFs being consistently higher than in the winter, due to a change in ionospheric chemistry. Unfortunately, this also means that daytime MUFs are lower than in winter, leaving 28MHz open to Sporadic-E instead.
According to DXMaps.com, it appears that most Sporadic-E openings on the 10m band have favoured the southeast of the UK towards Italy, Turkey and Greece.
Back to F2-layer propagation now. On the 20m band, E51JD, operating from the South Cook Islands, was spotted on SSB by Laurie, G3UML, on Thursday morning. KH7AL/KH9 on Wake Island, and T30TTT on Kiribati, have also been worked on the 20m band using FT8.
Next week, NOAA predicts that the solar flux index will be in the 125 to 145 range. Geomagnetic conditions are predicted to be quiet, apart from the period around the 11th and 12th of July, when the Kp index may rise to 4.
And now the VHF and up propagation news from G3YLA and G4BAO
This hot weather has provided some nice marine Tropo around the coasts recently as hot, dry air advects across the cooler, moist surface layer.
We have also been able to see the duct move inland in the evenings. The hybrid weather pattern of low pressure to the north of Britain and high pressure to the south will continue to produce some Tropo paths, particularly across the Channel, Biscay and North Sea. 
Northern areas of Britain will see occasional fronts and active weather systems, together with breezier weather, making Tropo unlikely here. The higher pressure to the south means that rain scatter may not feature much unless isolated thunderstorms develop when weak weather fronts eventually reach these southern areas.
In the north, it’s a different matter, and there could be some heavier rain that might produce some rain scatter on the GHz bands.
Meteor scatter did well during June with several important showers to boost chances. July offers two showers. The first is the low-hourly-rate Alpha Capricornids, and the second is the Delta Aquariids. Both of these peak around the 30th of July, so we have a while to wait.
There have been some minor auroral events recently, and it's always possible that solar activity could lift the Kp index high enough, but we are not expecting great things. Keep a check on the Kp index at spaceweather.com  to see if anything is happening.
The Sporadic-E season has had occasional good days, but for much of the time, the focus of activity has been too far into Europe for the whole country to take advantage of it. To begin the coming week, the position of the jet streams suggests paths to northern Europe and the Baltic will offer best results. Later in the week, the emphasis shifts to the Balkans and Italy, and then to Iberia.
The Moon reaches apogee tomorrow, the 7th, where path losses are at their highest. Moon declination is negative all week, with the lowest, or the most negative, on Wednesday, the 9th. 144MHz sky noise is moderate but increasing to a high of around 2,300 Kelvin on Wednesday.
And that’s all from the propagation team this week.

 Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 25th of June.
Last week was good from a geomagnetic disturbance point of view. Up until Wednesday the 25th, the Kp index had not been higher than 3.67 and had mostly been in the ones and twos. This helped HF propagation to a great extent.
Sunspots have been present with the solar flux index sitting at 120 on Wednesday, the 25th. A look at the visible disk at solarham.com  shows five sunspot groups facing Earth. None are ground-breaking, but they are at least helping to keep the solar flux index relatively high.
Daytime F2 MUFs over a 3,000km path have been reaching 18MHz and even 21MHz at times, with 14MHz being more reliable. Sporadic-E continues to make 28MHz a useful band for short-skip, with much of Europe being workable mid-morning on the 25th, at least using FT8.
Estonia, Germany, Poland, and Finland were all easily worked on FT8, but nothing was heard on the usual 10m CW and SSB frequencies.
Next week, NOAA predicts that the solar flux index will be in the 140 to 150 range. Unsettled geomagnetic conditions are forecast for the 1st to the 3rd of July, when the Kp index could reach 4. And conditions may become unsettled again on the 6th and 7th, again with a predicted Kp index of 4.
But in the meantime, make the most of the Sporadic-E on the 10m band, as it won’t last forever!
And now the VHF and up propagation news from G3YLA and G4BAO
The more traditional summer weather, with patchy rain and showers, is likely to continue for a bit longer. The more persistent rain is likely in the north, closer to low pressure near Iceland, whereas the rain may be more intermittent in southern areas, closer to high pressure over France.
This probably rules out any significant Tropo in northern Britain over the coming week but does allow for the occasional enhancement in the southern half of the country. Most areas will have some rain scatter opportunities for the GHz band operators, although perhaps fewer in the south than in the north.
The solar conditions have quietened down a little in terms of aurora recently but as we said last week, don’t forget to look north in the twilight sky for signs of the pale noctilucent cloud. This is a high-summer phenomenon. See if you can detect any wave patterns, like ripples on a sandy beach, in the cloud.
The month of June tends to be quite good for meteor input, and the last of the set, the June Bootids, peaked on Friday the 27th. So, there should be some good chances for hearing the odd ping or two or even seeing one in the evening sky after dusk.
The primary mode of interest is still Sporadic-E, which is in full swing and doubtless being topped up by the Bootids meteors, which produce the main ingredient of Sporadic-E propagation – long-lived ions as they ablate, or burn up, upon entering the atmosphere.
In terms of the usual search for the placement of Sporadic-E events geographically, the main jet stream interest is likely to be across the northern part of Europe for the coming week. This suggests trying paths to Scandinavia and the Baltic states, whereas for triggers due to upper air ridge patterns, use the more southern routes.
The Moon has passed perigee for this month, so path losses are rising. Moon declination is still high, not going negative until Tuesday, the 1st of July. 144MHz sky noise is low, increasing to moderate by next weekend.
And that’s all from the propagation team this week.

RSGB GB2RS News Bulletin for 22nd June 2025

The news headlines:
Introducing the RSGB’s team of young radio amateurs for YOTA Paris
The RSGB celebrates International Women in Engineering Day
The RSGB Exam Standards Committee publishes its annual report
The RSGB has announced the team of young members who will be representing the Society at this summer’s Youngsters on the Air camp. The event, hosted by the French national amateur radio society and the IARU, will take place at the historic Château de Jambville near Paris between August 18th and 25th. The team is comprised of team leader Leon, 2E0VUF, and team members Sophie, M7IJG, and Emily, M7HPU. You can read more about the camp and the team on the RSGB website at rsgb.org/yota-camp
The RSGB knows that amateur radio is a great foundation for careers in Science, Technology, Engineering and Mathematics, or STEM as it is often known. That’s why, for International Women in Engineering Day tomorrow, Monday the 23rd of June, the Society is sharing stories of female radio amateurs involved with STEM. From a young radio amateur who was inspired by an ARISS contact, through to a Professional Transmitting Engineer at Woofferton Transmitting Station, each one of them has a love for amateur radio and STEM activities and the career opportunities they present. Read more about them on the RSGB website at rsgb.org/inwed. The Society will also be sharing the profiles on its X and Facebook pages throughout the day tomorrow, the 23rd. Get involved by liking and sharing these motivational stories.
The RSGB Examinations Standards Committee, or ESC, has published its annual report, relating to activities in 2024. The report shows that overall candidate numbers have increased to above pre-pandemic levels and are well above the extrapolation of the declining trend over the decade before the pandemic. The ESC believes that this is probably due to the availability of remote invigilation for online examinations taken at home and the increase in provision of distance learning courses, making the hobby much more accessible than in the past. You can read the full report on the RSGB website by going to rsgb.org/esc  and choosing the ‘Minutes, papers and reports’ option in the right-hand menu.
Whether you are just starting to learn Morse code or are already an experienced operator, the GB2RS Morse Practice web page is just what you need to brush up on your skills! Created by GB2RS Newsreader Graham, G4JBD, you can select different sections of the latest RSGB news, which are then played in Morse code at the pitch and speed of your choosing. What makes this resource unique is that you can also add in different degrees of man-made noise and natural band noise, which gives you a very realistic experience of copying Morse code under poor propagation or contest conditions. Graham has recently updated the page with more options. One of these is the Farnsworth timing, which can play the individual characters at a selectable speed while allowing separate adjustment of the gap between the characters. The new version works well on smartphones and displays the text with a real-time pointer as the Morse code is sent. The GB2RS Morse Practice page can be found at tinyurl.com/gb2rsmorse

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 19th of June 2025.
Last week, we mentioned a large coronal hole on the Sun that might cause problems. The hole is so large that it is still Earth-centric seven days later.
We had expected the hole to increase the Kp index due to the solar wind emanating from it. However, as of Thursday, the 19th of June, conditions remained quiet with a Kp index of 2. As geomagnetic conditions have remained calm this past week, it has been quite good for HF.
15m has been one of the better bands, with openings to both the east and west, depending on the time. As is the way nowadays, most of the activity has been on FT8, but it has opened up opportunities to work the Far and Middle East, as well as South America.
The solar flux index has generally been in the range of 130 to 150, with a peak of 161 on the 15th of June. The Sun has been active, with a near X-class solar flare being observed around sunspot region 4114. This peaked at 1805 UTC on the 15th of June. There was also an X-class solar flare at 21:49 UTC on the 17th of June.
This latter event was late in the evening, so it had little impact on the UK, other than to potential paths to the west.
Maximum usable frequencies, or MUFs for short, declined a little during the past week, with openings on 21MHz becoming a little scarcer. It is useful to operate as close to the MUF as possible to minimise the effects of D-layer absorption and maximise the chances of working DX.
Next week, NOAA predicts the solar flux index will be in the range of 125 to 145. Unsettled geomagnetic conditions are forecast for the period from the 24th to the 27th of June, with a maximum predicted Kp index of 5.
If the Kp index is low, then we have a good chance of 21 MHz openings to South America in the evening. As we pass the summer solstice, we may even expect 14 MHz to remain open to DX throughout the night. We can also expect Sporadic-E to continue to provide short-skip openings on 28 MHz, and even the lower HF bands, such as 14, 18, 21, and 24 MHz.
And now the VHF and up propagation news from G3YLA and G4BAO
After a week of high pressure, this weekend returns to something more normal with showery rain and a series of weather fronts and showery interludes in the coming week. This will mean that rain scatter on the GHz bands is worth considering. Also, since we are into the summer season, the chances of some rain being heavy and thundery is a good signal for rain scatter.
This sequence of low-pressure weather suggests that high pressure and Tropo will be less likely to make a big impact on the coming week’s operating log. Any sign of high pressure will tend to be towards the south of the UK and over the continent. In very hot weather, the conditions can be good for low-level surface ducts across cooler seas. So, if you are tempted, then go for coastal or maritime paths up the east coast or across Biscay, for example.
Meteor scatter may benefit from the late June Bootids, which peak on Friday, the 27th of June and the daytime Beta Taurids, which peak on the 28th of June. These are small showers, but they can also be important for contributions to long-lived metallic ions, which are the building blocks of Sporadic-E propagation.
Aurora continues to appear with occasional radio events, but there is too much daylight for anything visual. As an alternative, you might see glimpses of noctilucent clouds low down on the northern horizon. These form in the mesosphere, at about 80km, as ice crystals form on meteor dust and can exhibit complex wave patterns. These are both good omens for Sporadic-E.
The summer Sporadic-E season is well underway now. It is advisable to check the usual cluster maps and the propquest.co.uk  website for daily updates. It’s also worth making use of the longer daylight and weather patterns over the polar regions for paths to the Far East.
The Moon reaches perigee, its closest point to Earth, tomorrow, the 23rd, so path losses are low. Moon declination also reaches a maximum positive value on the 25th of June. This will mean that there are long Moon windows. 144MHz sky noise is moderate, increasing to high by tomorrow, the 23rd. The New Moon is on the 25th of June, so expect high noise levels due to its proximity to the Sun.
And that’s all from the propagation team this week.

The news headlines:
Book now to secure your place at the RSGB 2025 Convention
The RSGB launches the “SES Cookbook”
The RSGB Operating Advisory Service issues advice
The RSGB annual Convention is a fantastic opportunity for radio amateurs to meet, learn and share experiences. Whether you’re newly licensed or have years of experience, there is always more to discover. That’s why the Society is excited to introduce this year’s theme: “Discover, Learn, Progress”. Whether you want to discover something new, learn more about a particular aspect of amateur radio, or progress and develop your skills, you’ll find something at the Convention to explore and enjoy. The prestigious event will take place between October 10th and 12th at Kents Hill Conference Centre in Milton Keynes. Book now to secure your place in joining like-minded people for what is also one of the best social events in amateur radio. Take advantage of the early-bird prices by going to rsgb.org/convention. The Society is delighted that the event will be sponsored again by Martin Lynch and Sons.
Special event stations are popular around the world and a great source of fun and excitement for organisers and QSO chasers. They can also be a fantastic tool for outreach, allowing you to demonstrate amateur radio and encourage people to find out more. But how do you organise an event to achieve all those objectives? The RSGB has just launched a new web section that focuses on special event stations. For RSGB members and Affiliated Clubs, there is an online guide called the SES Cookbook, which offers a wide range of practical guidance to help you deliver the best experience for your visitors and the organisers. The guide covers a wide range of topics, including how to apply for a special event station callsign, the stages of the planning process, publicising your event to attract visitors and how to make a good number of contacts. For non-RSGB members, there is a simple guidance document that outlines the main things to consider when planning this type of event. The new section also draws together existing information about permanent special event stations as well as QSL guidance. If you’re planning an event for this year, or even for next year, now is the time to make the most of this comprehensive guide. Go to rsgb.org/ses  to find out more.
The RSGB Operating Advisory Service, or OAS, provides advice to members on dealing with situations that are not within the spirit of amateur radio. From time to time, this activity goes beyond what is classed as acceptable behaviour and requires action to be taken. In these circumstances, the OAS recommends reporting the matter directly to Ofcom and to the police in the case of issues which could be classed as harassment, stalking or hate crimes. Experience has shown that this carries more weight coming directly from the people hearing or suffering the problem rather than a third party, such as the RSGB. If you hear anything that is not acceptable behaviour, contact the RSGB OAS first, and the team will suggest the correct course of action. Once Ofcom and the police have issued reference numbers, these should be passed to the Operating Advisory Service. You can contact OAS via oas@rsgb.org.uk
The RSGB has submitted responses to a pair of Ofcom consultations. The first considered a series of licence exemption updates, including arrangements for some visiting radio amateurs to the UK. The second concerned filing procedures for the growing number and variety of satellites. Both replies were developed by the RSGB Spectrum Forum, drawing on its members’ wide breadth of expertise. The Spectrum Forum expects that there will be further updates to both topics. Find the full replies by going to rsgb.org/spectrumforum  and selecting the ‘Papers and Consultations’ option from the right-hand menu.
The RSGB recently announced two new volunteering opportunities. The RSGB CW Champion will help the Society in taking Morse code to new audiences. Tasks will vary from developing the CW content on the RSGB’s website through to developing and supporting a team of enthusiastic individuals who can support CW-related activities. The second role requires an individual with experience in science, technology, engineering and mathematics. The RSGB STEM Champion will help the Society to reach new audiences, build relationships with related organisations and encourage more young people into STEM careers. Go to rsgb.org/volunteers  to read the full role descriptions and learn how to apply.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 12th of June 2025
Propagation was a mixed bag last week, with occasional Kp index rises but a solid solar flux index, which hit 141 on Thursday, the 12th. We also had some sporadic-E short-skip conditions on the HF bands, which brought some surprises.
We are now in June, so the summer HF doldrums are well underway. But that doesn’t mean that the fun has gone from the HF bands. Daytime maximum usable frequencies over a 3,000km path have been around 18 to 20 MHz, so the main active band has been 20m.
Paul, GM4ULS, reports that there was a spectacular inter-G event on the morning of Tuesday, the 10th of June. Whilst activating special event station GB70RS from Perth, he worked a mini pile-up of English stations from anywhere between Southampton and Manchester. This was between 0949 and 1022 UTC on 14.210 MHz. He said it sounded like the 40m band at times!
We think this was probably a Sporadic-E event, which often creates strong but short-lived paths across the UK on the HF bands in the summer. We normally think of Sporadic-E as affecting the 10m band, but the lower bands are also often implicated. Have you worked anything unusual via Sporadic-E? If you have, please send your reports to radcom@rsgb.org.uk
Otherwise, DX on the HF bands has been a little sparse, with paths opening to South Africa and South America on the 20 and 17m bands at times. Perhaps this is a good time to work some Summits on the Air or World Wide Flora and Fauna stations in Europe. These are usually QRP stations that appreciate your contacts.
Next week, NOAA predicts the solar flux index will be in the 120 to 130 range. Unfortunately, geomagnetic conditions are predicted to be unsettled, thanks mainly to the return of a massive coronal hole on the Sun.
Disruption was due to start around the 14th, but due to the hole’s size, this could continue for at least three days with a maximum Kp index of 6. Expect the HF bands to be disrupted with lower maximum usable frequencies as the plasma in the solar wind hits the Earth. It may be a good time for visible aurora hunting, though.
And now the VHF and up propagation news from G3YLA and G4BAO
The high summer conditions have brought an increasing chance of Sporadic-E, particularly on digital modes, with DXmaps.com  plots showing plenty of paths on most days.
Many of these are possibly associated with turbulence generated by jet streams in the weather part of the atmosphere. These send atmospheric gravity waves upwards to affect the E region.
It's this association with specific weather features that makes Sporadic-E sporadic in a geographical sense. If so, in the coming week, the jet streams are mainly over the northern fringe of Europe. These suggest a better chance of paths to Scandinavia with fewer options to the south to support paths to the Mediterranean and the Balkans.
In any event, June is high season for Sporadic-E, so remember to check the 6m band either mid-morning or late afternoon.
The early thundery weather at the end of last week was useful for rain scatter on the GHz bands, and it is just possible it will return for the end of the coming week.
In between times, it will be a high-pressure story that will dominate and may well produce some useful Tropo conditions. However, note that in the hot days of summer, inversion conditions and Tropo will be better at night and tend to weaken by the middle of the morning.
Meteor scatter will have been boosted by two showers on the 7th and 8th of June, and, since they were broad peaks, there should be some meteor input left to see us through the coming week.
For EME, sky noise is dropping. Low declination is now starting to decrease. So, Moon windows and peak elevation are improving. EME conditions are classed as poor to moderate today, the 15th of June, but are then good on the 21st and 22nd of June.
And that’s all from the propagation team this week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Thursday the 5th of June
Last week’s HF propagation was heavily influenced by unsettled geomagnetic conditions. This was caused by a combination of coronal mass ejections and a strong solar wind from a coronal hole.
The coronal mass ejection, or CME for short, followed a solar flare from sunspot 4100 on the 31st of May at 0005 UTC. The explosion lasted more than three hours. Type 2 radio emissions from shock waves within the CME cloud suggested it was travelling at 1,938 kilometres per second, or 4.3 million miles per hour!
Eventually, the Bz swung south. This meant that the interplanetary magnetic field more easily coupled with the Earth’s magnetic field. The result was that the Kp index got up to 7.67 on the 1st of June.
The auroral effects were reported as being due to a co-rotating interaction region, or CIR – a region in space where fast and slow solar wind streams collide, creating a compressed area with enhanced plasma and magnetic fields.
The Kp index was 7 or more for four three-hour periods. This pushed the maximum usable frequency over a 3,000km path below 14 MHz at times, which wasn’t conducive to good DXing.
On Thursday, the 5th of June, it looked like we were past the worst, and the Kp index was back to a more reasonable 2.33.
Meanwhile, the solar flux index declined from a recent high of 164 on the 31st of May to a low of 134 on the 5th of June. HF propagation was being driven by the geomagnetic conditions, with a general lowering of the maximum usable frequency.
Next week, NOAA predicts that the solar flux index will start the week at around 155 and remain around 150. More worryingly, geomagnetic conditions are again predicted to be unsettled after this weekend, with a maximum Kp index of 6 on the 13th of June.
So, unsettled geomagnetic conditions, plus the HF summer doldrums, mean HF DX via F2-layer propagation may be hard to find. So, make the most of the 10m Sporadic-E short-skip openings instead!
And now the VHF and up propagation news from G3YLA and G4BAO
Last week offered an example of what a good Sporadic-E season should look like. On Tuesday, the 3rd of June in particular, the 6m band sounded like the 20m band and, at its peak, activity extended all the way up to the 2m band.
This coming week has an unsettled flavour with several areas of low pressure and weather fronts involved, together with heavy showers in between. This means rain scatter will be a supported mode on the GHz bands.
There is a slight hint of a slow improvement during the week, but not really any high pressure showing up until right at the end of the coming week. So, there is a chance of Tropo propagation for the 2nd 144MHz Backpackers Contest on Sunday, the 15th.
Meteor scatter is always interesting in June, with four showers to play with during the month. The early ones are the Arietids, which peaked on Saturday, the 7th of June – good news for the 50MHz UK Activity Contest on Thursday the 12th.
The Zeta Perseids peak tomorrow, the 9th of June, and there will be a couple of other showers later in the month. This is probably also why the Sporadic-E prospects improve about now.
Aurora has also been much in evidence recently. Despite the light summer evenings and short nights, the chances of radio aurora continue to be important, so monitor for high Kp values above about 5.
The advice for some who have not yet worked Sporadic-E is to check the 6m band around teatime.
There are, of course, usually two primary periods when Sporadic-E is more likely: one in the morning, and the second in late afternoon and evening. A morning opening may repeat in the afternoon in similar locations, although usually the weather trigger may have moved a little in the meantime.
Check the jet stream charts at propquest.co.uk  by following the Sporadic-E blog tab. The daily commentary will highlight the important directions each day. You can hopefully test out the system on Thursday, the 12th of June, in the 50MHz UK Activity Contest.
EME path losses were at their maximum with apogee, when the Moon is at its furthest from the Earth, on Saturday, the 7th of June. Declination reaches a minimum on Wednesday, the 11th, so Moon windows are short and peak elevation is low. 144MHz sky noise peaks around the 11th and 12th of June. EME conditions were classed as poor this weekend and are classed as poor-to-moderate on the 14th and 15th of June.
And that’s all from the propagation team this week.
