Have you bought your ticket for this year’s RSGB Convention yet? The weekend’s draft programme has just been released, detailing all the inspiring speakers that the Society has lined up for your enjoyment. If you want to improve your technical knowledge, be sure to add the presentation by Hans Summers, G0UPL from QRP Labs, to your must-see list. Hans will introduce the concept of polar modulation SSB, along with the story of the practical implementation of polar modulation SSB in the QRP Labs QMX and QMX+ transceivers. Perhaps you’d like to get some operating tips? In which case, Walt Hudson, K4OGO, is one to add to your weekend schedule. Walt, also known as ‘Salty Walt’, will discuss different types of antennas and his experience with them when operating portable. If you’d like to discover something new within amateur radio, then join Kjetil Vinorum, LB4FH, for a presentation on ‘elmering’ in an online world. In addition, Mike Walker, VA3MW, will present an exclusive look at the new Aurora transceiver from FlexRadio Systems and will showcase how the Aurora pushes the boundaries of software-defined radio. With a wide-ranging programme to spark your interest, three exciting workshops, the Special Interest Groups room, GB3HQ and much more, this year’s Convention is one not to be missed. The event takes place between Friday the 10th and Sunday the 12th of October at Kents Hill Conference Centre in Milton Keynes. Tickets are selling fast, so to view the full programme and book, go to rsgb.org/convention
The RSGB has announced an exciting new volunteer role, which will be tasked with attracting older people to amateur radio. The Honorary Mature Members’ Officer will also be responsible for retaining and engaging with our existing senior members. The individual will research organisations or groups with memberships that include older people who may be interested in amateur radio as a hobby. They will also help to identify ways the RSGB can support lifelong enjoyment of amateur radio, including accessibility, training and social engagement. If you are an RSGB member and interested in this role, go to rsgb.org/volunteers to read the full description. If you’d like to apply or have a chat about the role, email the Nominations Committee Chair, Will Richardson, 2E0WYA via nominations.chair@rsgb.org.uk
The RSGB will have a large presence at the National Hamfest at Newark Showground on Friday, the 5th and Saturday, the 6th of September. In addition to an extensive book stall and membership stand, the Society will be running a range of exciting practical activities and demonstrations. These include a semi-interactive display of the CubeSat and a web-based dashboard from a Tiny Ground Station running remotely. There will be the opportunity to play ‘MORSE’, a minimalist, wave-based strategy game operated with just two controls. You can also have your CW skills tested at a range of speeds. On Saturday, there will be an opportunity to get hands-on, building a Kanga FM receiver kit. The activities are all free of charge, and there is no need to book in advance. Members of the RSGB Board, staff and representatives from specialist committees and teams will also be in attendance and are looking forward to meeting you, answering your questions and offering support.
If you know an up-and-coming HF DXer who has made rapid progress in the last year and has some real achievements to show, you have until Friday, the 12th of September, to nominate them for the RSGB’s G5RP Trophy. The award is not limited to youngsters or the newly licensed but is open to anyone who has recently discovered and made significant progress in HF DXing. Please email your nominations to Ian Greenshields, G4FSU, via hf.manager@rsgb.org.uk

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.
