Each RSGB Board Director has a liaison role between the Board and
specific aspects of the Society's work. This focuses very much on the
work done by RSGB volunteers in committees, groups and teams as well
as by the Honorary Officers. The Board has just agreed the liaison
roles for the coming year. To find out more or to see contact details

The Signals Museum at RAF Henlow is closing soon. Its final open day
will be on the 8th of June 2024. According to the Museum's website,
after this time it will start to dispose of its exhibits. The Museum
attempts to tell the story of RAF Signals. Among its attractions, it
contains a lot of working equipment which can be demonstrated,
including transmitters, receivers and radar consoles. To read more
about the Museum, and learn how you can visit it before it closes,

The UK Six Metre Group Summer Marathon is under way. The activity is
open to all amateur radio operators worldwide and membership of the
Group is not required. The objective is to work as many four-digit
grid squares as possible between the 4th of May and the 4th of August
on the 6m band. Logs can be submitted until the 18th of August 2024.

year to celebrate the work of the volunteers from the Royal National
Lifeboat Institution, Independent Lifeboats and National Coastwatch
Stations around the British Isles. A commemorative certificate is
available to all official stations that record their contacts on the
website together with awards for the top individual and club, or
group, stations on each band from 160m to 70cm. To read more about
the event visit sosradioweek.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO
on Thursday the 16th of May 2024
After last weekend's auroral spectacular it was nice to see the Sun
calm down a little and the bands get back to normal. But that didn't
last long.
To recap, on Friday the 10th of May the Kp index shot up to 9, due to
the effects of a number of coronal mass ejections, while the HF bands
closed down in the subsequent geomagnetic storm.
While there were visible aurora across the UK and Europe, HF
propagation really suffered and didn't start to recover until the
late afternoon on Saturday the 11th.
The main culprit, active region 3664, has now rotated out of view,
but that doesn't mean we are out of the woods just yet.
Solar flares can cause short-term disruption to HF propagation due to
their X-rays penetrating deep into the D-region and causing signals
to be absorbed. Subsequent coronal mass ejections can cause
longer-term degradation of the F2 layer with reduced maximum usable
frequencies, noisy bands and auroral conditions.
At the time of writing, the Kp index stood at 6 again so it looks
like unsettled geomagnetic conditions are continuing with a moderate
G2 geomagnetic storm in progress.
Low to moderate activity is now expected, with a slight chance of
further strong-class flares. The regions currently on the visible
disc are smaller and simpler, with isolated M-flares possible from
these. However, a new active region, now rotating into view, has
already emitted an X-class solar flare.
Next week, the United States Air Force predicts that the solar flux
index may remain in the 160 to 180 range. HF conditions remain a
lottery as they can be badly affected by solar flares and coronal
mass ejections.
It is best to keep an eye on solarham.com for updates, and also
propquest.co.uk for near real-time reports of the critical and
maximum usable frequencies.
And now the VHF and up propagation news from G3YLA and G4BAO
The weather remains on the unsettled side of things with areas of
rain and some thunderstorms over the country, especially the south as
we end this week. As this report is being read out, high pressure is
becoming established over northern and western Britain.
This may eventually take a tenuous hold over the rest of the country
during the second half of the coming week and into next weekend, the
25th and 26th.
This high pressure, although fairly weak, may help with some Tropo
for those in northern Britain in the 144MHz May Contest and the
Backpackers Contest this weekend, ending the 19th. It may also be
helpful to those taking part in the 1.3GHz UK Activity Contest on the
21st. However, the conditions may not be of much use in the south as
another low arrives from the continent.
Overall, rain scatter on the GHz bands will probably be worth
exploring in the rainy areas again, since some of the showers may be
heavy and thundery.
The prospects for aurora are still worth keeping in mind despite the
recent stunning event. Minor non-visible events can still provide a
reasonable radio aurora to explore.
The Sporadic-E season continues to develop. And with such unsettled
weather, there are plentiful jet streams to act as source regions for
turbulence, which can propagate up to the E region where they can
generate Sporadic-E.
We are currently at the tail end of the Eta Aquariids meteor shower.
A few meteors from this shower will continue to appear, but no major
shower is expected this week.
The lowest Moon declination occurs this coming Friday. With the Moon
being full on the 23rd, a clear sky should reveal an impressive
‘Flower Moon'. For EME, path loss will still be relatively high,
although the Moon is starting to move back towards its closest point
to Earth, or perigee.
144MHz sky noise starts the week low but rises to high on Saturday
the 25th.
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.
