Thanks to Chris, G0FDZ for giving a fascinating talk to the club this Wednesday on the microwave bands. Chris is one of the few amateurs in the UK that is operational on the bands up to 241GHz, what he calls the other ‘Top Band’. On display were three of his homebuilt transverters, some of which are dual band capable, covering in total 24GHz, 47GHz, 76GHz, 134GHz and 241GHz. All using an FT-817 as an IF.
Chris, G0FDZ gave us an excellent talk on the inner workings of the beacon GB3VHF on Wednesday. Chris explained how the beacon had evolved from valve based equipment using paper tape keyed morse, right up to the present beacon which uses the latest digital techniques including GPS frequency lock, JT65 and carrier phase reversal.
The talk was enjoyed by all club members that were present and the club thanks Chris and all who maintain GB3VHF for their work.
