GB2RS Main News for Sunday the 9th of July 2023
The news headlines:
* New ATV display at the RSGB's National Radio Centre
* Film award for members of Aberdeen Amateur Radio Society
* International Lighthouse and Lightship Weekend
A new amateur TV display has just been installed at the RSGB's
National Radio Centre, with signals received via the wide-band
segment of the geostationary satellite QO-100. The Society is
delighted to be able to demonstrate amateur TV as a permanent display
at the NRC, helping to highlight yet another exciting aspect of our
technical hobby. A special configuration, developed in conjunction
with the British Amateur Television Club, incorporates a touch screen
from which visitors can select a signal to be tuned, decoded and
displayed on the large monitor. The RSGB would like to thank Justin,
G8YTZ for designing the display and working with the BATC for the
specially adapted configuration.
A short film produced by members of Aberdeen Amateur Radio Society
has won a top award at the 2023 Doric Film Festival. The film was
joint winner in the ‘Groups' category of the prestigious festival
that showcases the distinctive Doric language and culture, most
closely associated with North-East Scotland. The film includes a
specially written fiddle music theme, based on Morse code. You can
find the film by searching for ‘Aberdeen Amateur Radio Society
Groups DFF Entry' on YouTube.
A reminder now that International Lighthouse and Lightship Weekend is
coming up soon. The event is usually held on the third weekend of
August which this year is the 19th and 20th. It is one of the most
popular amateur radio events in the calendar and in past years there
have been more than 500 entries from over 40 different countries.
More details about the event and a registration form can be found at
illw.net
There is so much happening at the RSGB's National Radio Centre that
it needs to expand its team of volunteers! If you can volunteer at
weekends, you will be particularly welcome. The National Radio Centre
has a fabulous set-up and full training on using the GB3RS radio
station will be given. You will be joining a friendly and dedicated
team. NRC volunteers also enjoy numerous benefits associated with
volunteering at Bletchley Park. You should enjoy meeting people and
be able to volunteer for one or two days per month. For more
information please email NRC Coordinator Martyn Baker, G0GMB
via nrc.support<at>rsgb.org.uk
Please send details of all your news and events to
radcom<at>rsgb.org.uk The deadline for submissions is 10am on

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO
on Thursday the 6th of July 2023
NOAA's prediction that the Solar Flux Index, or SFI, would decline
last week didn't come to fruition. In fact, the SFI stayed in the
160s and 170s until Thursday, when it declined to 155.
The Sun produced more than 160 sunspots in June, the highest monthly
number in more than two decades. This has led some newspapers to run
more doom and gloom stories about solar Armageddon, while we amateurs
look forward to some F2-layer DX!
Unfortunately, more sunspots do mean more chance of solar flares and
coronal mass ejections, but we have to take the rough with the smooth.
As an example, we had an X1-class solar flare on the 2nd of June.
This occurred at 2314UTC so didn't affect the UK, but did cause an R3
radio blackout over the west coast of the USA and Pacific.
Otherwise, there is still DX to be bagged for well-equipped stations,
such as Eric, FP/KV1J on the St Pierre and Miquelon islands on 12m
FT8, and Marek, FH4VVK, on Mayotte island, on 10m FT8. Other DX
worked this week by CDXC members includes the 4W6RU DXpedition on
Timor Leste on various bands; Robert, 9N7AA in Nepal on 12m FT4; and
V31XX in Belize on 20m CW.
Next week, the Space Weather Prediction Centre has the SFI at 155,
rising to 175 by the end of the week. Unfortunately, the Kp index is
forecast to rise to four over the weekend, possibility due to a large
Earth-facing coronal hole, and again up to Kp five on the 12th and
13th. If it happens, expect noisy bands and a decline in the maximum
usable frequency.
As always, we encourage you to get on the HF bands, in the evening,
nighttime and especially around dawn, which is when a lot of HF DX is
being worked.
And now the VHF and up propagation news
Low pressure dominates the whole weather pattern this coming week,
driven by an active meandering jet stream across the Atlantic.
This provides several regions where the turbulence, generated on the
edge of these strong winds up at 10km, can propagate upwards to
trigger Sporadic-E propagation at about 110km height in the E region.
So, unsurprisingly, Sporadic-E will feature as a ‘go to mode' for
the coming week. Typically, single-hop paths within Europe will
produce very strong signals, whereas multi-hop paths, for example
across the Atlantic, will require several such refraction points from
Sporadic-E patches, plus intervening reflections from the sea
surface, and will have much higher losses.
These will usually be weak signals and probably very fleeting in view
of the complex geometry of such paths.
Tropo need not concern us this week, but rain scatter is worth a look
since the unsettled weather will provide several heavy rainfall
events in some areas. Look for the brighter echoes on the rainfall
radar displays, especially those associated with thunderstorms.
Random meteors could be useful in the early morning hours. We also
have the start of two showers, Alpha Capricornids and Delta Aquarids,
during next week, which don't actually reach a peak until the end of
July. So prospects for meteor scatter and Sporadic-E propagation are
improving this month.
The aurora chances may be reasonable initially in view of the recent
coronal hole transition, so keep an eye on the Kp index.
Moon declination goes positive on Sunday so there will be lengthening
Moon windows. Path losses are currently low but will rise all week.
144MHz sky noise is low to moderate all week.
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.
