GB2RS Main News for Sunday the 18th of February 2024
The news headlines:
* Ask the RSGB Board a question during the Society's 2024 AGM
* Get involved with British Science Week
* Registration is now open for Maritime Radio Day 2024
Over the last few years, the RSGB has been developing the way in
which the Board can be asked questions at the Society's online AGMs.
Last year people were able to ask questions via the YouTube live chat
as well as submitting written questions in advance. This year, in
response to members' feedback, there will be an opportunity to ask a
question on video via Zoom. The RSGB Board will still take written
questions in advance and will also answer as many questions on the
day via the live chat as possible, depending on time. The RSGB AGM
will be held on Saturday the 13th of April and you can find more
information about how to take part on the Q&A subpage of the RSGB AGM
web section at rsgb.org/agm
The RSGB has a collection of resources to help you get involved with
British Science Week, which runs from the 8th to the 17th of March
this year and has the theme of ‘Time'. If you already have
something planned, please let the RSGB know. This will be useful for
others to see and might inspire them! There are already several
events for British Science Week on the RSGB website. Some of these
are open to everyone, so please show your support for them. If you're
going on the air, tell everyone when to listen out for you by sending
the RSGB dates, times, bands and modes. The RSGB's British Science
Week coordinator is Ian Neal, M0KEO and you can contact him via
bsw<at>rsgb.org.uk Please send Ian the resources you'd like to share
and your event details including the times you'll be on the air. All
details are on the RSGB website at rsgb.org/bsw
Registration is now 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 as Friends of
Maritime Radio Day. Shortwave listeners may also submit logs. For
more information and to register, visit tinyurl.com/MRD24
There are less than two weeks to go until the deadline for the RSGB
Construction Competition. There are six categories to enter this
year: Antennas; Beginners; Most creative and/or elegant PCB Design;
Construction Excellence; Innovation; and Software and Systems. To
enable members from across the country, and even the world, to enter,
entries will again be judged over the internet rather than in person.
Special recognition will be given to entries submitted by radio
amateurs under the age of 24, and to those who have just gained their
Foundation licence. A cash prize will be awarded for the winner of
each section, with a bonus for the overall winner, who will also be
declared the winner of the Pat Hawker G3VA Award. You can find out
more, including how to enter, on the RSGB website at
rsgb.org/construction-competition Don't forget, the deadline for
entries is the 1st of March 2024 so get your entry in before it's too
late.
Lots of amateur radio stations have been on the air this weekend, in
conjunction with The Guide Association, to celebrate World Thinking
Day on the Air. The aim of World Thinking Day on the Air is to
encourage Guides to make friendships with members of other units,
using amateur radio as the means of communication. If you, or your
club or society, were on the air during the event don't forget to
send your pictures and stories to radcom<at>rsgb.org.uk Please send
your reports in by the 23rd of March.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO
on Thursday the 15th of February 2024
We had an interesting week with the threat of a major coronal mass
ejection at any time with so much sunspot activity. In the end, it
pretty much amounted to nothing, with the highest Kp index only
reaching 4.33 on February the 11th.
That's not to say we didn't have solar activity. Far from it, as the
solar flux index reached 208 on the 12th and has been consistently
above 180 all week. We also had high proton levels as the positively
charged particles streamed past Earth. This was the result of an
eruption early on Monday morning from beyond the southwest limb. This
may have affected HF signals going over the poles.
Otherwise, we had numerous low-level solar flares to contend with,
but none of them were stronger than M-class and so of little
consequence.
So where did this leave us in terms of HF propagation? All in all,
not bad with maximum usable frequencies, or MUFs for short, over
3,000km consistently above 28MHz in daylight hours. In fact, daytime
MUFs were peaking above 33MHz according to the Dourbes ionosonde.
Looking further ahead, we are now heading towards the equinox period,
so we can expect MUFs to fall from their winter highs. The good news
is that we can expect north-south paths to improve. The equinox is
traditionally a better time for auroral conditions.
If you want to work the USA on 28MHz you still have a couple of
months left to do so, but expect transatlantic propagation conditions
to decline by the time April arrives. The good news is that
propagation to South Africa, South America and the Caribbean may
improve.
Next week, NOAA predicts that the solar flux index may reduce and be
in the range 155 to 165. Geomagnetic conditions are predicted to be
quiet but, as always, keep an eye on solarham.net for a near
real-time update as the risk of a coronal mass ejection, or CME,
remains high. To recap, an Earth-facing CME could increase the Kp
index, reduce MUFs and generally give poor HF propagation for up to a
day or so.
And now the VHF and up propagation news from G3YLA and G4BAO
The basic weather pattern remains unsettled with a series of frontal
systems crossing the country during the period. This leaves little
room for any Tropo other than the occasional transient ridge of high
pressure between successive weather systems. It does however give
plenty of scope for rain-scatter enthusiasts to try their luck on the
GHz bands.
The solar conditions continue to give hope for an increased
geomagnetic Kp index, which would be a good signal for potential
aurora if it goes above 5 as evidenced in visual displays over
northern Britain last Tuesday night, the 13th and 14th of February.
As usual, the other propagation modes can still surprise us, even
though this is not strictly the best time of year. The large number
of satellites in operation means that QSOs can be guaranteed even
with simple hand-held equipment. So, have a look at the AMSAT-UK
pages and the RSGB website for details and give it a go!
Also, a reminder that the best time for random meteor scatter QSOs is
around dawn, and that the high solar flux could see some 50MHz
openings if the Kp index remains low, especially for the far South
and West of the UK.
For EME operators, the moon reaches peak declination today, Sunday
the 18th, so activity should be higher with high peak moon elevations
and long moon windows. Path losses are moderate but rising and 144MHz
sky noise is moderate, but falling after Monday.
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.
