“Millimetric Microwaves” by Chris, G0FDZ

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.

50 MHz Trophy Cup, 21-22 June 2014

Members of the Havering & District Amateur Radio Club took to the air operating as G4HRC/P for the 2014 50MHz Trophy Cup. Equipment was an Icom IC-7700 transceiver, 6-element 6 metre beam and 12 metre SCAM pneumatic mast.

During the 24 hours of activity, starting 2pm UTC on Saturday, we managed to rack up around 150 QSOs in conditions which where a little above average.  Best DX was a tie between EA8 and IZ1 both very close to 3000 km.  Splashes of sporadic-E were noticed, but these patches where few and far between (hence sporadic!).

A map of QSO’s can be seen here.

GB3VHF talk by Chris G0FDZ

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.

Chris, G0FDZ
