RSGB 2nd 70MHz Contest


M0UKD/P – 70MHz

We had some great September weather today for the 2nd 70MHz contest. We setup at the Kelvedon Hatch ‘Secret Nuclear Bunker’ as seen above, using my new 70MHz amplifier at 160w and my 4 element DK7ZB 12.5Ω Yagi.



Conditions seemed quite normal, we worked no Scotland or Ireland but our best DX (as many others) was PA4VHF at 449km. Other highlights were GJ3YHU in Jersey and M1CJN/P in the North York Moors. Total contacts was 46.

A very enjoyable day of operating and testing the new amplifier. Next week, it’s the Practical Wireless 70MHz contest, so lets hope for the same weather and some band openings perhaps? Maybe I’m asking too much 🙂

The Claimed Scores are available. Thanks to Dave M0TAZ, George M1GEO, Dave M0YOL and Chris G8OCV for help & company, and of course everyone we worked (or tried to work!).

Operation Bunker

Our club took part in Operation Bunker at the Kelvedon Hatch ‘Secret’ Nuclear Bunker at the weekend. Operation Bunker was a military vehicle, memorabilia and re-enactment weekend attended by vintage military personnel from all over the South East.

We operated the bunker special call GB0SNB from beside the main mast, using SSB, CW and Data modes.  In total we contacted 368 stations in 47 countries around the world. Our best DX was into Chile at 11,330 KM on 14 MHz digital modes. I used my IC-7200 for data on Saturday, with my end fed half wave vertical on 20m and higher bands. On the Sunday, we used an IC-7100.
