The normal stance of amateur radio is that it is apolitical. However, it is clear that recent actions by the Russian Federation and their military have crossed a line and the RSGB cannot in this instance remain neutral.
The policy of the RSGB is that we will follow the actions of the mainstream sporting bodies with regard to all activities of a competitive nature such as contests and ARDF. Russian and Belarusian radio amateurs are therefore currently ineligible to participate in any event that is organised/sponsored by the RSGB.
The policy of the RSGB in commercial activities is that we will refrain from trade with Russia and Belarus until further notice.
For RSGB Contests, until further notice, all logs received from stations in the Russian Federation or Belarus will be treated as check logs.
I have recently been using a half G5RV; very effective for medium distance communications and occasionally Dx.
I recently tried to set up a CW practise sked into north Devon on 40m (7.0 mhz), signals were very weak RST 218 sent at 100 watts with QRM and QSB. Seems this may be the skip zone. The answer could be NVIS antennas which could also give an opportunity for HF SSB club net, and more contacts in the uk, WAB and SOTA .
Seems worthy of an experiment so Rex and myself will try some experiments as weather allows.
Today the wx forecast was cloudy and windy but no rain; I traveled to Bredon Tower with my Hand held 2/70 Baofeng. It was wet and slippery under foot and my skying experience was very useful going downhill on muddy wet grass!. I activated the summit talking to G8LDP in Worcester on 5 watts a qso of 18 miles on 2m, thank you Keith. The round trip from the car park was 3 miles and the elevation for the walk was 184m from the car park. If your interested in joining me on one of the activations i would be pleased with your company.
On Christmas Eve morning, Friday December 24th 2021, SAQ Grimeton is scheduled* to be on the air, to send out a Christmas message to the whole world, using the 97 year old 200kW Alexanderson alternator on 17.2 kHz CW.
Transmission & YouTube Live stream 08:25 CET (07:25 UTC): Live stream on YouTube begins. 08:30 CET (07:30 UTC): Start up and tuning of the Alexanderson Alternator SAQ. 09:00 CET (08:00 UTC): Transmission of a message from SAQ.
Test Transmissions We are planning to carry our some test transmission on Dec 23rd, approximately between 13:00 CET (12:00 UTC) and 16:00 CET (15:00 UTC). SAQ will be on air shorter periods of time during this interval, when we will be carrying out some tests and measurements. Your comments are welcome to firstname.lastname@example.org.
In addition the following stations will be broadcasting simultaneously:- Amateur Radio Station SK6SAQ The Amateur Radio Station with the call “SK6SAQ” will be QRV on the following frequencies: – 3.535 kHz CW – 7.035 kHz CW – 14.035 KHz CW – 3.755 kHz SSB – 7.140 kHz SSB
Today John m3eqq and Rebecca and myself M0hfh put the club antenna 10m in the air slung between two trees on nylon rope. We are using an 80m rectangular loop this year courtesy of Garry g7nvz having ratios of L1 (30m) to L2 (10m) total length one wavelength (80m) which has a theoretical gain of 4db compared to a dipole. We will be using the Yaesu 450d with the club manual ATU; Generators should give the full 100w output.
The Field Day site is at GL13 9TH hook street, field located behind Hook House 51°41’44.0″N 2°28’16.7″W
John Rowden M0hfh (@johnrowden59) tweeted at 10:28 am on Thu, Aug 12, 2021: Well done Peter, we always knew you were clever, and that was before your degree, keep going we will be proud to have Dr. Peter Barnes in Tsgarc. Best wishes from all at club in Thornbury. (https://twitter.com/johnrowden59/status/1425751055682478084?s=03)
Well perhaps the way we calculate and the calculators and computers we use to get the answer. Our test equipment and radio’s have also taken a great leap forward; I have smiths charts on my analyser these days where it used to be complicated and time consuming to get the resolution to complex number problems.

I like to try some of the old designs and compare the performance with some of the improved antenna designs we have today,( Roll on Field day 2021) but mostly its the detail of the design description that leads to ideas for improvements.
