Bank Holiday Radio Weekend

August is the last Bank Holiday of the year, and with the weather set to be 30c+, it provided the ideal weekend to play some radio.

Sunset over SNBCG

Members of LEFARS and SNBCG came together at Kelvedon Hatch Secret Nuclear bunker for a 3 day radio weekend, including BBQ and camping. Some members of the advanced party arrived on Friday evening helping to set up the operating tents.

The 40m vertical was the first antenna to go up, this included 4 elevated radials.

7 MHz vertical antenna

The next antenna was the 3e 18 MHz beam, this was fitted onto the 12m SCAM mast.

18 MHz 3e homebrew beam

The operating tent was completed with the IC7300 and IC7610 and Expert 1.3K solid-state amplifier.

Peter was delighted to use the 7 MHz vertical and linear, commenting on how much fun it was to run a pile-up! The weekend was all about having fun and trying out new things, Dick G4DDP completed a number of QSO on 50 and 70 MHz working SPe all over EU.

John M0IDA working some DX

Special thanks to John who repaired my headset with a mono jack plug he desoldered from his own headset. Thanks, John!

Vintage Dave also decide to operate in period costume, adding to the nostalgia of his vintage wireless experience.

The BBQ provided by some excellent food, thanks to Ron and Karen for setting this up and Dave M0MDB for his Chillie.

Thanks to Piotr for this clip, it gives you some idea how busy 7 MHz can be on a field day.

We put 1030 QSO in the log, in 52 DXCC from both 7 and 18 MHz, thanks to everyone who took part and made the weekend a success.

Part 3

Members of the Havering ARC took part in the LEFARS radio event over the bank holiday weekend 23/24/25 May provided the ideal opportunity to test the beam. George M1GEO and Chris G8OCV provided the 12m SCAM mast and so the fun began. The club operated from a farm site in Harlow, giving us enough space to test even the most ambitious projects. As described in parts #1 and #2 the antenna has a 5 meter boom, and although it isn’t too heavy it still provides a challenge lifting this onto the mast.

Once again a quick VSWR check using the MFJ antenna analyser suggested it was ready to go, and so the next phase was to pump up the mast. The Scam provides 12m (45ft) of elevation, and provides a suitably robust (heavy) construction that makes it a firm favourite for our HF field days.

Its up

The station was a Kenwood TS990 and Explorer 1200 Amplifier. Here is a picture of George M1GEO working a pile up.

Over the course of the next 3 days we were able to test the antenna, band conditions seems reasonable on the day and improved early evening on most days. We found the directivity to be good, and pointing towards Japan in the early evening provided a pile up of JA’s calling us.

Some highlights VU3DMP Chetz from India

Some really nice calls from Japan as well including JJ1LWA Hal near Tokyo using 200w and 3E beam

We also found conditions very good into the USA late evening and working West coast with signals 59+ was quite a surprise. It was also nice to see the GB2LRS station generating some interest on the HF band, with one USA station suggesting the phonetics should be GB2 Loud Radio Station !

The USA and JA pile ups were quite a surprise, listen to one here and see what you can pull out.

The the weekend finally coming to an end on Monday we had worked 600 stations in 58 countries, the highlights being A9 Bahrain, C6 Bahamas, BY China, VU India, HI Dominican Republic, EP Iran, P2 Papua New Guinea, KL Alaska, XE Mexico, and YB Indonesia. The top two countries in the log were 376 Q into USA and 71 into Japan.

I think given the quantity and quality of stations worked this weekend I can now declare the 4E mono band for 21 MHz a success. Thanks to everyone who worked us and made the weekend possible.
