Once again members of the LEFARS came together at the Rainbow and Dover PH near Harlow to play some radio. George M1GEO and Chris G8OCV had recently serviced a tri band beam from Cushcraft A-3S donated by Bill G0BOF to the SNB group. The event this weekend was its first field day outing, and it performed very well. The antenna worked as a 3e trapped beam on 28, 21 and 14 MHz bands.
The boom length of the antenna is just 4.17m and the longest element length is 8.45m. You can download a manual for the antenna here.
The 3e beam was supported on the 12m SCAM pump us mast, as was the 3.5MHz dipole. We also operated on 50 MHz and 70 MHz using a slim Jim and dipole.
Using 2 x Icom 7100 for HF, one connected to the Cushcraft beam, and the other on 70, 50 or 3,5 MHz. The amplifier was a solid state HAL 1200 delivering 400w to the antenna,
7 MHz was also in use giving John the chance to try out his newly acquired Icom 7300. The new Icom is proving very popular, with 3 club members recently investing in this new mode.
Over the weekend we made close on 300 QSO, and combination of CW, Phone and Data modes.
Here you can see Fred G3SVK working a few on 14 MHz CW.
