well as information on Friday's tour of Bletchley Park and the RSGB
National Radio Centre. Don't forget that if it is your first time at
the event, pop along to the new ‘Welcome desk' that will be set up
in the bar on the Friday evening. If you're going to the Convention,
remember to make sure you have your QR code ready to collect your
badge at the conference centre. This can either be on your mobile or
as a printed copy. The QR code can be found in your purchase email,
as well as in the reminder email which will be sent out this week. If
you are unable to travel to the Convention, the RSGB will be
livestreaming a selection of lectures. Find out how to join the
livestream via rsgb.org/livestream If you have tickets for the Gala
Dinner on Saturday and wish to reserve a table with friends, send

Jamie Williams, M0SDV will be talking you through a DXpedition to the
Marshall Islands for the RSGB's next Tonight<at>8 webinar tomorrow,
the 6th of October. In February 2025, the V73WW team made 103,864
QSOs using CW, SSB, RTTY and FT8. The team of six came from four
countries, with the operators having an average age of only 28. Jamie
is a 24-year-old radio amateur who has been involved with the hobby
since 2015 and has been busy with contests and DXpeditions ever
since. The Tonight<at>8 webinars are livestreamed for free on the
RSGB's YouTube channel and special BATC channel, allowing you to
watch the presentations and ask questions online. Go to
rsgb.org/webinars for more information.
Jamboree on the Air, also known as JOTA, is taking place between the
17th and 19th of October. The event promotes friendship and global
citizenship and is a brilliant celebration of amateur radio among the
groups within the Scout Association. Samuel McCutchion, M0UEL is the
RSGB Youth Champion for Scouts, Cadets and Guides, and he is
compiling a list of JOTA stations which will be shared on the RSGB
website. Sam is encouraging everyone to get involved either by
putting a station on the air or listening out for the JOTA stations.
If you are part of a Scouting group and are planning to get involved
with JOTA then please contact youthchampion.scouts<at>rsgb.org.uk
with a summary of your station name, callsign and any other relevant
information.
The RSGB is offering four awards for GB2RS news broadcasts that were
logged between the 1st of August and the 30th of September. The
awards are part of several activities that have been taking place to
celebrate the 70th anniversary of the weekly news broadcast.
Applications for awards should be submitted no later than the 31st of
October 2025, and should be sent to the RSGB Awards Manager via
awards<at>rsgb.org.uk The certificates are free of charge and will
be supplied as a PDF. Find out more via rsgb.org/gb70rs
On Wednesday the 8th of October, YouTuber James, M0GQC will be
broadcasting his next live episode from the RSGB National Radio
Centre. James will be active from approximately 6.30pm on the 40m
band using the GB3RS callsign. His channel <at>HamRadioOnline is an
interactive show where people can call in or simply watch the station
live on YouTube. If you haven't already got the Centre's callsign in
your logbook, this is a great opportunity to do so.
The next Essex CW Amateur Radio Club Boot Camp will be held on
Saturday the 18th of October 2025. Due to cancellations, a few places

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO
on Thursday the 2nd of October 2025
Last week was characterised by very unsettled geomagnetic conditions
with a Kp index that reached 7.33 on the 30th of September and was
often above 5. This is not good for HF propagation!
But what caused this? A high-speed solar wind stream at around 750
kilometres per second, coupled with the Bz component of the Sun's
magnetic field pointing south, led to the disruption. But there
didn't seem to be any particular solar event that triggered the
high-speed solar wind stream.
The Russell-McPherron effect is probably to blame. This is a
phenomenon where the alignment of the Earth's and the Sun's magnetic
fields, during the equinoxes around March and September, allows
charged particles from the solar wind to more easily penetrate the
Earth's magnetosphere.
This enhanced connection leads to more intense geomagnetic storms and
increased aurora activity as the Bz aligns favourably with the
Earth's magnetic field at these times. This may pass as we get
further into October.
As a result of the geomagnetic storm, maximum usable frequencies, or
MUFs, have often been lower than normal. A quick listen on 28MHz on
Wednesday the 1st of October confirmed the poor conditions. It's a
shame as October is normally a fantastic month for HF DX.
The solar flux index peaked at 187 on the 30th of September, having
been above 170 since the 28th of September.
Next week NOAA predicts that the solar flux index will remain above
150 to 160 all week. The good news is that geomagnetic conditions are
forecast to improve, with a maximum Kp index of 3. If that comes to
pass, we can expect HF to be better after a day or two, and we might
be able to make the most of the autumnal conditions for DX.
And now the VHF and up propagation news from G3YLA and G4BAO
The current spell of unsettled weather, mainly over northern areas,
is typical of the season, but it's also common to find high pressure
passing by in between the deeper lows. In the current pattern, the
highs are mainly for the southern half of Britain. This will bring
some good Tropo conditions at times for the VHF and UHF bands.
As we head into autumn, these lifts may linger through much of the
morning on some days before the temperature rise breaks down any
temperature inversion. A good clue is that it's usually over when the
overnight fog clears.
On the other hand, there will probably be some good rain scatter
opportunities on the GHz bands as the active lows push fronts across
the country, especially in the north. There are signs that we may
return to high pressure over the country during the RSGB 2025
Convention weekend from the 10th to the 12th of October.
We have a meteor shower to play with during the coming week. The
Draconids peak on Wednesday the 8th of October, but the shower stream
is spread over the whole of the week.
Lastly, there have been some reasonable auroral events recently so,
as usual, keep a watch on the Kp index going over 5 since, as we said
earlier, these autumn months are very much favoured for auroral
activity.
For EME operators, the Moon's declination is increasing and goes
positive tomorrow, the 6th, so lengthening Moon windows and
increasing peak elevation is the story for the coming week.
Path losses continue to fall as we approach perigee on the 8th of
October. 144MHz sky noise will be low for much of the next seven days.
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.
