Chris is the only amateur in the UK to have had a two-way QSO on every single amateur band for which we are licensed. Chris has been Vice President of Cray Valley Radio Society for over 20 years, and members of the club turned out in force to see the presentation and celebrate his achievement. A reminder that this year's RSGB AGM will take place at 10am on Saturday the 13th of April. It is being held online to ensure as many members as possible can watch and take part. The formal business of the meeting will include the results of members' votes on the resolutions, including the endorsement of three Nominated Directors. RSGB members are encouraged to vote on all the resolutions. This year you can ask the RSGB Board a question in one of three ways: by submitting it in advance via an online form; registering to ask a question live on video via Zoom; or asking via the YouTube live chat during the event. There are deadlines for submitting questions via the online form or Zoom so make sure you don't miss those! Find out more on the RSGB AGM web pages at rsgb.org/agm At the Discussion with the Board session at the RSGB Convention last year, the President John McCullagh, GI4BWM committed the Board to giving regular updates on work being done to fulfil the RSGB's strategic priorities. Since the beginning of this year, a monthly report has been shared in RadCom and on the RSGB website. These reports have covered a range of activities and achievements involving both staff and volunteers. The Board is committed to continuing this regular communication so look out for the updates in RadCom each month. If you've missed any this year, you can find them all on the RSGB website at rsgb.org/strategy-updates Are you aged 18 to 30? Are you passionate about all things radio?

The March 2024 edition of RadCom Basics is now available on the RSGB website for members to read. RadCom Basics is aimed at new licensees or anyone who enjoys reading about the fundamental principles behind the many facets of amateur radio. This edition includes articles which cover: the checking and testing of components; working on the 160 and 80m bands with limited space; the importance of antenna radials; what it's like to take up portable operating; and a guide to clean transmissions. To read RadCom Basics visit rsgb.org/radcom-basics At its recent meeting, the CEPT Frequency Management Working Group confirmed that Barry Lewis, G4SJH, in his IARU role, would continue as Chair for a further three-year period, having first been appointed in 2019. The meeting also noted updates to T/R 61-01 that facilitates the temporary operation in a fellow member's country, for Georgia joining the scheme, as well as editorial changes to accommodate Australian licence changes and Canadian provincial prefixes. Barry has also continued his work in CEPT on the 23cm band, following the outcomes from WRC-23. IARU and RSGB volunteers are also starting ITU WRC-27 preparations, where further bands and topics are of concern to amateur radio. Please note that RSGB HQ will be closed for the bank holiday on Monday the 1st of April. Please continue to send all of your news and updates to radcom<at>rsgb.org.uk The deadline for the GB2RS News is 10am on Thursday before the Sunday broadcast.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Wednesday the 27th of March 2024 What a tumultuous time we had last week. Active region 3614 produced an X1.1 solar flare and coronal mass ejection, or CME, in the early hours of the 23rd of March. This impacted Earth's geomagnetic field sending the Kp index to 8 on the 24th of March. In fact, there were simultaneous flares from active region 3614 and the larger region AR3615. The solar wind speed reached more than 850 kilometres per second at the height of the geomagnetic storm, peaking at 880 kilometres per second. The CME started to impact the Earth early in the afternoon of the 24th and, according to Digisonde data, its full effects on the ionosphere started to be felt by 1540UTC. The large AR3615 sunspot cluster continues to evolve as it moves into the Sun's southwest quadrant. Moderate flaring will remain likely in the short term with a lower chance for another strong X-class flare, although it is around the side of the Sun and is not considered a threat today, Sunday the 31st. All this was not good news for HF propagation, which saw maximum useable frequencies over a 3,000km path plummet on the 24th to less than 18MHz. The ionosphere didn't fully recover until two days later, with the MUF struggling to get above 18MHz on the 25th. It wasn't until the afternoon of Wednesday the 27th that we saw the 10m band behaving normally again with the Kp index back in the range of 1 to 3. So, this is what can happen if we have an X-class flare and associated CME. We can expect more of the same to come. Next week, NOAA predicts that the solar flux index will remain high at around 175 to 190. Unsettled geomagnetic conditions are forecast from the 3rd to the 5th of April when the Kp Index could rise to 4. But keep an eye on solarham.net for a near real-time guide to current solar conditions. And now the VHF and up propagation news from G3YLA and G4BAO The period leading up to the Easter Weekend, and the following week, shows up on the forecast charts as dominated by low pressure, feeding several periods of rain and showers across the country. This unfortunately means that Tropo is again off the menu of weather-related VHF propagation. Of course, wet weather is usually very supportive of rain scatter propagation on the GHz bands and this prolonged period of rain or showers will give the UHF and SHF operators something to occupy their time. Meteor scatter prospects are once again just random, which tends to be better in the hours just before dawn. We can start to look forward to the April Lyrids, which are active in the second half of April with a peak around the 22nd. It's worth checking out the operating conventions and frequencies now so that you can be ready. Strong aurora has been reported recently, with a Kp index of 8, and a quick listen for fluttery signals on the 80m or 40m bands is often a good clue if you don't have access to the Kp index at the time. The main mode of interest for the coming months is Sporadic-E and some early propagation is possible, mainly on digital modes on the 10m or 6m bands, but probably very fleeting. During the summer Sporadic-E season, it's well worth checking the propquest.co.uk graphs to see what is occurring and get an idea of how it may relate to jet stream weather patterns by cross-checking with the Sporadic-E blog upper air charts. The Sporadic-E Probability Index, or EPI, maps are also potentially useful to see how the favourable regions change with time. In the current pre-season period, it's more typical to find trans-equatorial propagation, or TEP, as an exotic mode offering paths to the south into South Africa and possibly into South America. For EME operators, Moon declination reaches minimum on Easter Monday, so we'll see short Moon windows with low elevation. Path losses are falling all week and 144MHz sky noise is moderate, rising to a peak of more than 3,000 Kelvin on Easter Monday before returning to low levels. And that's all from the propagation team this week. And that's the end of the main news for this week prepared by the Radio Society of Great Britain. Items for inclusion in subsequent bulletins can be emailed to radcom<at>rsgb.org.uk to arrive by 10:00 on the Thursday before transmission.
