RSGB statement: the Russian Federation and Belarus

 

 | March 4, 2022

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.

RSGB Board

For RSGB Contests, until further notice, all logs received from stations in the Russian Federation or Belarus will be treated as check logs.

NVIS antennas

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.

Let me know if you set up and NVIS antenna and want to try some experiments

CQ SOTA CQ SOTA Bredon Tower G/CE 003 My first activation of 2022.

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.

Field Day 28th 29th 30th August 2021 Preparations are under way

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

Antenna Handbook 1937

Has anything changed in the maths since 1937?

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.

The link below takes you to Frank Jones antenna handbook

Still valid today? – leave a reply 

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.
