Suffolk Red hosted a field weekend from their field day site at the Suffolk Aviation Heritage site near Ipswich. The weather was set fine, with temperatures close to 30C and with the option to camp out for the weekend.
George M1GEO, Chris G8OCV and I set up the operating tent and populated it with the following equipment.
HF – Icom 7610 and 1.3K Linear from expert
VHF – Icom 7100 and 300w VHF amplifier from Linear amp UK
RACAL push up mast
Power – Honda 2KW generator
The object was to try something new, so I opted for 9e LFA on the Racal push up mast and tried to work as many EU stations as I could on both phone and FT8. VHF seemed quite lively, and with good take off into Europe I was soon working into France, Germany, Denmark and Belgium.
LMR 400 coax was used to keep the losses down, and the masthead amp compensated for any RX losses.
Masthead amplifier for 144 MHz was originally published in the RSGB magazine RADCOM plus issue 1 designed by Ian White GM3SEK. The details are published on his website, detailed as the DG8 low cost, high-performance preamp for 144 MHz.
Over the course of the weekend I completed 50 QSO in 25 squares, the map is shown below. If you are new, or even not so new to FT8 you may find this operating guide helpful.
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.
