VHF Contest May 22nd 2011

Comments Off on VHF Contest May 22nd 2011

On Sunday May 22nd, Tony G4LDL, Andy G0UWS and Steve M0AKT, and later assisted by Phil M0PBZ and Graham M3XIR, set up the SDARC caravan on a windy hill near Liddington to run the 2m Contest. Using the club callsign, G8SRC/P, activity was brisk and at times, quite busy, rather like an 80m HF contest. No doubt the excellent location helped as we received favourable reports from all directions using just 100w and a rotatable 5-element Yagi antenna with gamma match. This was one of the first occasions that we used our own Kenwood TS2000S transceiver. After some initial challenges with the very high winds, we were away. The 25 foot winch-up tower was kindly provided by Andy G0UWS.

Operators on the day were contest stalwarts Tony G4LDL, Andy G0UWS and Steve M0AKT. Phil M0PBZ and Graham M3XIR assisted with the rigging and technical set-up. Band conditions were variable, with some occasional tropospheric propagation. We logged 84 QSOs in all, in 44 postcodes and 7 DXCC entities. With multipliers our score reached 613938.

So despite the windy conditions, all in all, we had a successful day and it provided some useful experience for the forthcoming VHF National Field Day event in July. For those interested in the contest side of Amateur Radio, the club has its own amply sized caravan, with awning, which allows us to operate in all weathers, in comfort. If you’re a lapsed Amateur thinking about returning to the hobby, or if you’re interested in finding out more about contesting or about Amateur Radio in general, please contact the Membership Secretary, Phil M0PBZ at m0pbz(at)

Well done to all !

Latest News On UKube-1 Project

Comments Off on Latest News On UKube-1 Project

Here is some good news just released by the UK Space Agency about the UKube-1 project.

You will see that the FUNcube system is formally part of the project. Whilst the release does not mention the FUNcube linear U/V transponder function during evenings and weekend, this functionality will be included in the same way that it is planned for the actual FUNcube-1 cubesat itself!

The FUNcube development team is looking forward to the extra challenge of producing two sets of everything in the very short timescales required by both projects:,,)

It is also good to se that they are proposing to use 9k6 BPSK as the modulation of the other VHF downlink transmitter that will be sued on UKube-1. Of course the FUNcube dongle and all the usual software will be perfect for receiving such signals. (About 6kHz bandwidth with the receiver in SSB mode if I understand it correctly)

2m Trophy – And the winner is…?

Comments Off on 2m Trophy – And the winner is…?

The 144 MHZ trophy results are out and I have the greatest pleasure in telling you the club entry was 2nd out of 16 entries in our section.

We only put a very small station with a 5 ele beam on a portable mast without a rotator and 80w. Just think what we could have done with the club beams & tower.

Full results can be seen here.

We lost a total of 7 QSOs which ultimately lost us 1973 lost points. Having had a 100% log would have made no difference to the final result.

It was exciting to see that the winner of the OPEN section logged 902 QSOs. That is fantastic for a VHF contest although they did use 4*12 + 4*10 + 17 ele yagis.
