Are you an RSGB member? Have you voted on the AGM resolutions? The deadline for voting is 9 am on Thursday the 11th of April. Online voting is available 24 hours a day, so make sure you use your vote before then. Registration for asking a question live via Zoom has now closed but there is still time to submit a written question in advance – this is the only way for members to ask a question during the formal part of the meeting. During the later Q&A sessions, written questions will be answered before any are asked via YouTube live chat. The AGM itself includes the results of the voting, the Honorary Treasurer’s report, a video review of the year by the RSGB President, as well as announcements of trophies and construction competition winners. There will also be a presentation by Ofcom Group Director, Spectrum, David Willis who will talk about “Making amateur radio licensing fit for the future”. After this presentation, there will be a live Q&A session on the new licence conditions with four senior RSGB representatives. Be part of this important annual event and take the opportunity to ask questions of the Board and about the licensing conditions. The RSGB AGM will take place at 10 am on Saturday the 13th of April on YouTube – be part of it! Find out more on the RSGB website at rsgb.org/agm

Don’t forget that the RSGB has launched a new opportunity to get even more out of your RSGB membership. If you recommend a friend who hasn’t been an RSGB member during the last 12 months, you will both receive £10 cashback when they become a member paying by direct debit. Whether you’re an individual RSGB member or an affiliated club, you can sign up as many friends as you like. Membership of the RSGB gives you a range of fantastic benefits so why not encourage others to join? Members have access to RadCom, exclusive online resources, RSGB award schemes and contests, as well as advice from the Society’s specialist committees. The RSGB’s representation to Ofcom and its ability to defend the spectrum nationally and internationally is more powerful through strength in numbers.

The latest Tonight@8 webinar is taking place tomorrow, Monday the 8th of April. Whitham Reeve will be looking at high-frequency aurora reflections observed at Anchorage in Alaska in the United States of America. The presentation will include an overview of early investigations and concepts that underlie the observations of aurora reflections and instrumentation. It will also include a selection of spectrum images from 2020 showing aurora reflections. Watch this live presentation on the RSGB YouTube channel or special BATC channel and ask questions via the live chat. To find out more go to the RSGB website at rsgb.org/webinars

Are you making the most of the new amateur radio licence conditions already? Or are you still discovering what has changed and how it applies to you? The RSGB website has a range of resources about the Ofcom consultation, the new licence conditions and where to find help and guidance. You’ll find videos, summaries and links to Ofcom’s documentation. This is also a good time to revalidate your licence. Go to rsgb.org/licence-review to find out more and remember to be part of the RSGB AGM if you have a question you’d like to ask.

A reminder that registration is open for Maritime Radio Day 2024 which takes place annually on the 14th and 15th of April. The event is held to commemorate the almost 100 years of wireless telegraphy service for seafarers which ended with the closure in the UK of Portishead Radio on the 30th of April 2000. Commencing at 1200UTC on the 14th of April, and finishing at 2300UTC on the 15th of April, this event is a great opportunity to have a QSO with ex-Marine Radio Officers and Coast Station professionals who exchange details of their previous ships and coast stations. The mode of operation is CW and all of the HF bands are used, including the WARC bands. A certificate of participation will be issued to everyone who submits results. Amateur licence holders are invited to register to take part in Friends of Maritime Radio Day. Shortwave listeners may also submit logs. For more information and to register, visit tinyurl.com/MRD24

Lots of stations are on the air today to join in with this year’s Airfields on the Air event. Amateurs are invited to contact as many of the stations as possible. To learn more about the event, and read a list of registered stations, visit tinyurl.com/2024AOTA

Tomorrow, the 8th, a total solar eclipse will head toward the UK from the west. While not visible over the UK, it will likely affect transatlantic VLF and HF radio propagation. RSGB Propagation Committee associate member Gwyn Griffiths, G3ZIL has a particular interest in the effect of reduced ionisation during the eclipse on second and third hops on 15 to 10m paths from the UK to North America. He encourages occasional WSPR users to dust off their transmitters to operate on those bands from today, the 7th, through to Tuesday the 9th of April, not just on the 8th, to provide results on undisturbed days.

Now the Special Event News

Special event station GB0WYT will be active from RAF Wyton during the Airfields on the Air event on the weekend of the 13th and 14th of April. This is the 12th year that a special event station has marked the event. The callsign will again be operated by RAF Air Cadet Communication Staff and club members from the Huntingdonshire Amateur Radio Society. This year, due to restrictions, the activity will be run from a site just west of the main runway at Wyton. Operators will be active on the HF bands, subject to working conditions, using CW, phone, RTTY, PSK31 and FT8. FM and SSB will also be in use on the 2m band.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 4th of April 2024

Looking at the Sun on Wednesday the 3rd of April, you might be forgiven for thinking we are near sunspot minimum!

With a near-total lack of sunspots and a solar flux index of 112, the solar disk was looking pretty bare. Compare that with just two weeks ago when the solar flux index was sitting at 209 on the 23rd of March.

But never fear, there seems to be some activity coming up. Two active regions, AR3627 and AR3628, have just rotated into view, but in the meantime make the most of the geomagnetically-quiet conditions.

10m propagation is still holding up, although you may find that the band opens a little later in the morning and shuts earlier in the afternoon. The 4X6TU and VK6RBP IBP beacons were both audible at 0945UTC on Thursday the 4th, while China, Japan, Mongolia and Thailand were copiable on 10m FT8, even with a lowish solar flux index.

Higher HF band propagation from the UK has moved from favouring North America to north-south paths, notably to South Africa and South America.

Next week, NOAA predicts that the solar flux index will rise a little, perhaps starting at around 135 and finishing at around 150. Geomagnetic conditions should be reasonably quiet with a maximum Kp index of 3, unless we get a coronal mass ejection that could send it soaring.

As always, keep an eye on solarham.net  for current conditions.

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

There have been reports of trans-equatorial QSOs on 144MHz from Southern Africa to the Southern Mediterranean, but here in the UK we can only dream due to our northerly location.

The next period of weather is unfortunately shaping up to be the same as most of the recent ones, dominated by low-pressure systems driving active weather fronts across the British Isles.

It means that Tropo conditions seem unlikely to feature much through to the end of the coming week. Rain scatter for the GHz bands remains the mode of choice with help from some heavy April showers. Meteor scatter options are still best with random meteors before dawn, but we are getting closer to the April Lyrids shower later this month, so not long to wait now.

The solar conditions have subsided a little recently, but we remain in scope for further activity, especially since April can be one of the more active months for Aurora. Watch out for fluttery signals on HF or VHF bands, use the various clusters, or save the frequency of one of the northern beacons in your rig’s memory.

This is a good time to suggest updating your list of favourite beacons on the 10, 6, 4 and 2m bands since they’ll be useful for the upcoming sporadic-E season too.

It’s a good time to take an early look at the sporadic-E prospects before it gets properly busy.

Some background rules which may help are to use propquest.co.uk to see where the jet streams are since Sporadic-E propagation is often associated with turbulence in regions of jet stream activity. Then look for a relatively low Kp index. The other main rules are related to timing. Usually, there are two windows of opportunity, one in the morning and a second in the late afternoon or early evening. However, at the beginning of the season, these are approximate.

Sporadic-E starts on the lower bands like 10m and, if strong enough, will gradually extend to the higher bands. The 10 and 6m bands are probably the ones to check this month.

For EME operators, Moon declination goes positive again on Sunday, which is also Moon perigee, its closest point to Earth, so we’ll see lengthening Moon windows, increasing elevation and low path losses. 144MHz sky noise is low until Monday’s total solar eclipse, then moderate for the rest of the week.

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