The RSGB Commonwealth Contest runs from 10:00 on Sat 9th March to 10:00 Sun 10th March. You will hear participants calling CQ BERU (British Empire Radio Union). This is a CW contest in which the participants must be in commonwealth countries such as Australia, New Zealand, Canada, Ghana, The Gambia, Grenada to name a few. A full list of Commonwealth Call Areas may be found at Stations from those areas may also work Headquarter stations including those from their own call area. The contest details may be found at

Bob G3PJT maintains an interesting site at with the latest news about participants, especially those travelling to some far-flung part of the commonwealth. Our own Don G3XTT will be operating as C56DF from The Gambia. I’m sure he would be delighted to work as many RADARC members as possible!

One of the advantages of this contest is that it is easier for UK stations to work DX because you are not competing with most of Europe or the USA. Saturday afternnoon is worth trying for African stations on 20m. You should also be able to work many Canadians on 20m from mid-afternoon to mid-evening, and on 40m during the evening. It’s worth getting up on Sunday morning to operate between about 06:00 and 07:30 as you’re likely to work VK and ZL on 40m and possibly 80m. There’s a very noticeable lift around UK sunrise that coincides with sunset in ZL.

RADARC in RSGB AFS contests

RADARC participated in three RSGB AFS contests in January – CW, Datamodes, and Phone. Each was of 4 hours duration on 40m and 80m. Typically stations started on 40m and as propagation changed, moved to 80m. In all three legs, it was very noticeable that GM stations had much better conditions on 40m than the Gs, and hence GM stations tended to be the winners or runners-up.

RADARC came 6th in the Local Club category with a team consisting of Don G3XTT, David M0DHO, Jim G0LHZ, and Michael M0MPM. I stayed on 40m longer than many, and this helped to reduce the time at the end of the contest whenI had worked everything on 80m. For details, see

AFS Data
RADARC came 24th in the Local Club category with a team consisting of David M0DHO, Michael M0MPM, and Simon M0ZSU. This was my first attempt at a datamodes contest and using N1MM and MMVARI to send RTTY and PSK, and I treated this as a learning exercise. For details, see

AFS Phone
RADARC came 14th in the Local Club category with a team consisting of David M0DHO, Jim G0LHZ, Jonathan M0JSX, and Michael M0MPM. Dealing with the inevitable QRM is one of the challenges. Running with 400W meant that I was able to keep my run frequency on each band. For details, see
