GB2RS News

Sunday, the 17th of May 2026

The news headlines:

The RSGB Exams Team is pleased to publish new mock exam papers for Foundation and Intermediate levels. There are three for each level, and you can find them on the RSGB website at rsgb.org/mock-exams. These take into account all the changes to the syllabus and exam question bank which have been made since the last sets of mock exam papers were published. The Exams Team will not be publishing new mock papers for the Full level as the entire Full licence question bank is now available online. Candidates and Trainers can create their own full-level mock papers using the questions at rsgb.org/exam-questions

The RSGB is running a practical and thought-provoking workshop for radio amateurs, makers, and home constructors, who want to understand what AI really is, what it is good at, where it can go wrong and why it matters. The session will run during the RSGB Convention on both Saturday, the 10th and Sunday, the 11th of October. It will use plain English and real examples from personal projects and will show how large language models can act as useful thinking partners for learning, writing, coding and building. At only £15 for a two-hour session, this is an opportunity not to be missed. As well as this, the Society is running an additional workshop on Friday, the 9th of October. In this six-hour workshop, you will learn how to use the NanoVNA effectively, understand its practical limitations and apply it confidently in your shack. You will also learn to calibrate the device correctly and complete hands-on exercises using your own NanoVNA. This RSGB member-only workshop costs £50 and includes lunch and refreshments. Both workshops are filled on a first-come, first-served basis and are limited to 20 people per session. Book now at rsgb.org/convention

Listen out for RSGB National Radio Centre Coordinator Martyn Baker, G0GMB on Milton Keynes Hospital radio tomorrow, Monday the 18th of May. Martyn met presenter Sophie at the Hospital Broadcasting Association’s annual conference in March, when NRC volunteers spoke with attendees about amateur radio. During the interview, you’ll hear Martyn talking about a range of topics, from why amateur radio can be an exciting and rewarding hobby to his work at the Centre and the role of the RSGB. He will also explain how amateur radio can contribute to mental well-being and prevent social isolation. You can listen to the broadcast from 1 pm by going to mkhrs.org.uk  and selecting ‘click to listen’ in the top right-hand corner.

Today, Sunday the 17th of May, is the last day of Mental Health Awareness week, and this year’s campaign looks at taking action to support good mental health. The RSGB highlights some of the small actions that radio amateurs can do that can have a big impact. This includes showing kindness to one another, listening to each other and taking a few extra minutes to engage in a conversation. Over four days in May and June, Humber Fortress DX Amateur Radio Club is playing its part in raising awareness for men’s mental health. Club members will be operating special call sign GB0MMH, and they are inviting radio amateurs to make contact. As the club says, let’s break the silence one transmission at a time. Find out more on QRZ.com  and support this great initiative. If you have a story you’d like to share that relates to amateur radio and mental health, please email [email protected]

Please send details of all your news and events to [email protected]. 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 Thursday the 14th of May 2026

We hate to start the report on a negative note, but we are about to experience unsettled geomagnetic conditions over the next few days.

The culprit is a large coronal hole on the Sun, which rotated into an Earth-facing position on Thursday, the 14th of May. This large coronal hole, an area with open magnetic field lines, has already been responsible for an increase in the solar wind speed to more than 420 kilometres per second. We can expect it to get worse as the weekend progresses. The hole spans the solar equator, so it is ideally placed to create maximum disruption to Earth.

If the Bz interplanetary magnetic field swings south, we could see the Kp index rise and maximum usable frequencies, or MUFs, decline. If this happens, expect poor conditions until tomorrow, Monday, the 18th of May.

Meanwhile, the solar flux index declined to 103 on Thursday, the 14th of May, which starts to put us in a difficult spot. Usually, we say that a solar flux index of 100 or more is needed for the 10m band to open. So it may be that you’ll need to move lower in frequency for reliable HF openings.

DX to be worked next week includes 3B9IDX from Rodrigues Island, T31TTT on Kanton Island, the last few days of XT2AW from Burkina Faso, and FO/F6BCW in French Polynesia.

The Propagation Studies Committee’s space weather station at Baldock identified a solar flare on Sunday, the 10th of May. The Doppler Flash, or Sudden Frequency Deviation, was triggered by an M5.7 solar flare that began at 1319UTC. While ‘Flash’ is a good term for the fast-rising edge, the GB0PSC receiver has captured fine detail on the 20MHz signal from the WWV station in Colorado, showing multiple oscillations over a few minutes.

X-ray radiation from the flare quickly increased absorption in the D region, reducing signal levels into the noise after ten minutes. But those minutes are crucial as they provide data to test whether X-rays or extreme UV from the flare were responsible for the Doppler shift and propagation anomaly.

Next week, NOAA predicts that the solar flux index could rise to be in the 120 to 130 range, which puts us back in the fun zone. Unfortunately, and for the reasons mentioned earlier, we can expect to see a Kp index of 5 this weekend, but it will eventually decline to perhaps 2 or 3 as the week progresses.

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

The background pattern of unsettled weather remains with us for a while over the UK as a whole, but subtle changes from a cold northerly to a warmer southerly wind will bring higher temperatures back again.  

To end the previous week, the cold northerly has brought some heavy showers with hail and thunder in places, and the GHz bands will have seen some rain scatter opportunities. The transition to a more southerly origin of the air will be taking place over this weekend, and although high pressure develops later in the week, we may have to wait until after midweek for any chance of tropo.

The next few weeks encompass a couple of minor meteor showers, the Tau Herculids and daytime Arietids, to add to the random background input. There should be something to interest those looking for meteor scatter activity, and of course, it all contributes to the ‘fuel’ for Sporadic-E, which is largely comprised of meteor ionisation. 

The solar activity has recently been offering a few minor enhancements of the Kp index, but no great results on the aurora front. 

Sporadic-E has been producing results on 6m digital modes, where there have been brief openings to VK, XT, DU2 and the USA for those lucky enough to catch them. The usual technique of checking during the two main activity windows of mid-morning and late afternoon should improve your chances.

If you get an opportunity to look at the jet stream patterns, it can be worthwhile trying paths that cross these since it’s believed they are good sources of atmospheric gravity waves that can reach the E region to aid the production of Sporadic-E.

EME now: with maximum declination, the period of longest moon windows, now almost coinciding with perigee, the period of lowest path loss, conditions are at their best for the northern hemisphere. Moon declination is positive, reaching maximum tomorrow, Monday, the 18th of May. Path losses are at their lowest as we reach perigee today, the 17th. The 144MHz sky temperature is low all week.

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