GB2RS News

Sunday, the 12th of October 2025

The news headlines:

• Introducing the RSGB mobile app
• Join the RSGB 2025 Convention livestream
• Get involved with Jamboree on the Air

The Society is excited to announce the launch of the RSGB mobile app. This fantastic new members’ benefit allows you to enjoy RadCom, RadCom Basics and RadCom Plus wherever you are. Complementing the RSGB’s existing web app, with the new mobile app, you can save editions to read offline, bookmark articles to enjoy later, and have seamless access to extra digital content. With easy-to-use navigation, the app is your one-stop shop for RSGB publications. You can download it now via the Apple App and Google Play stores or go to rsgb.org/radcom  for the links.

The second day of the RSGB 2025 Convention is well underway with a great line-up of presentations. If you have been unable to attend in person, you can catch up with the livestream on the Society’s YouTube channel via youtube.com/thersgb. The livestreams for both days will remain available for everyone to watch and offer a programme full of engaging speakers to help you discover, learn and progress within amateur radio. Presentations include Radio Communications Foundation Trustee, Andy Webster, G7UHN, who explains how you can use radio technology to engage and inspire non-radio amateurs. Hans Summers, G0UPL of QRP Labs, talks about polar modulation, and you can also watch a fascinating panel discussion in which representatives of four amateur radio groups or societies discuss what they have been doing to help their club thrive. Whether you’ve attended the Convention in person or watched the livestream, the Society would love to hear your feedback. Share your thoughts on the event by going to rsgb.org/feedback  for those who have attended the event and rsgb.org/livestream-feedback  for those who watched the event online.

Thank you to everyone who has responded to the RSGB’s call for Jamboree on the Air participation. Samuel McCutchion, M0UEL, is the RSGB Youth Champion for Scouts, Cadets and Guides and has compiled a list of Scouting groups that are involved with the annual event. To view the list, go to rsgb.org/jota  and select the ‘JOTA Stations on the Air’ link on the right-hand side of the page. If you are planning to get involved with JOTA and would like to be added to the list, please get in touch via youthchampion.scouts@rsgb.org.uk  with a summary of your station name, callsign and any other relevant information. The RSGB would love to see your photos of Scouts getting involved with JOTA, so tag @theRSGB and also use #JOTAJOTI to be involved in the conversation on social media. If you’re not involved with a JOTA station, do listen out for them on the air and encourage the young operators. This year’s event is taking place between the 17th and 19th of October.

Volunteers at the RSGB National Radio Centre had a particularly busy weekend at the end of September. It was 1940s weekend at Bletchley Park for which the Centre set up the GB1SOE station, and over the weekend, RSGB volunteers welcomed almost 1,100 visitors through the doors. If you’d like to be part of this engaging and motivated team, the NRC Coordinator is currently looking for a volunteer specifically to join the Friday team. If you’d like to find out more about this role, email Martyn Baker, G0GMB via nrc.support@rsgb.org.uk

RAF Air Cadets Exercise Blue Ham will take place on the 60m band from 0700 to 1600UTC over the weekend of the 18th and 19th of October. To operate, you must be a Full licence holder. More details can be found on the alphacharlie.org.uk  website.

The RSGB wishes to record, with sadness, the passing of GB2RS Newsreader Peter Valentine, G0NQZ, at the grand age of 101. Age was no barrier to Peter. At a mere 96, he walked 96 miles for his local hospital charity, and he was still broadcasting GB2RS from Eastbourne in his 100th year. He was described by a fellow Newsreader as a true ambassador for amateur radio. Peter had a wonderfully distinctive voice on the air, and for many years, he also read a talking newspaper for the blind. Our thoughts are with Peter’s wife, Heather and family.

Please send details of all your news and events to radcom@rsgb.org.uk. The deadline for submissions is 10 am on Thursdays before the Sunday broadcast each week.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 8th of October

We finally got rid of the high-speed solar wind stream, which caused havoc on the HF bands. But we are not out of the woods yet!

Last week saw the Kp index hit 6.67 on the 2nd of October, and it was often up around 4 or more. Even though the Kp index eventually reduced, the ionosphere took its time to recover, and things were not back to near normal until Tuesday, the 7th.

Meanwhile, the solar flux index decreased to 131 by the 8th, so the HF bands were hardly humming by this time.

DX on the 10m band was hard to find. Openings to Europe were commonplace, but longer paths were not so good, with only weak North American stations being heard later in the day.

A minor G1 geomagnetic storm watch was in effect for 48 hours from the 7th of October, when at least one faint coronal mass ejection was predicted to pass the Earth. Only minor C-class solar flares occurred during the week, but that didn’t help too much.

CDXC members were reporting DX, such as V85T in Brunei on 15m and A52G in Bhutan on 20m – both using CW. However, there was not much to work on the higher bands. Southerly paths were a little better with 5X2I in Uganda reported on the 17m band using FT8.

Next week, NOAA predicts that the solar flux index will be in the range of 130 to 140, but it is also predicting geomagnetic disturbances today, the 12th. After that, the Sun may quieten a little with a maximum Kp index of 2 for the rest of the coming week before more geomagnetic disturbances. The Kp index is forecast to be 4 or 5 during the weekend of the 18th and 19th.

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

The coming week is dominated by high pressure, either over the UK or near enough to influence the propagation and provide a prolonged period of Tropo weather.

It's probably worth mentioning a few ground rules about Tropo operating. Firstly, large areas of high pressure can produce widespread lift conditions due to the strength of the elevated temperature inversion 1 to 1.5km above the ground. The longer the high lasts, the lower this descends, so limiting the maximum distance across the centre of the high.

Try beaming around the edge rather than across the centre. Secondly, there may be surface temperature inversions at night or in foggy weather, and these will provide temporary enhancements. Thirdly, the clue for a good ‘radio’ temperature inversion is the presence of fog or layers of cloud, which give a better moisture contrast and ducting prospects.

One last point. Try other modes like SSB or CW rather than sticking to repeaters which can get very crowded in lift conditions.

There is no rain scatter in the frame this week, and the Draconids meteor shower has just passed, so back to random activity on that front. On the 8th of October, the Sporadic-E graphs at propquest.co.uk  showed that there had been occasional spikes up to 5MHz or so. This may liven up the 10m band if we get any more. There have been a few weak auroral events, but nothing too exciting.

For EME operators, the Moon’s declination is still increasing, reaching its peak today, the 12th, so long Moon windows and high peak elevation continue. Path losses are rising again after perigee on the 8th. 144MHz Sky noise will be moderate to low for the coming week.

And that’s all from the propagation team this week.
