Not sure what happened. I was out last night at the Salop ARS 50^th anniversary dinner, so the Rx was on auto. However Stefan’s signal was increasing over the same period. His signal was strong enough to produce some odd sidebands at +/- 0.5 Hz – I guess in my Rx? The grid-lines are at 22:00 and 23:00 UTC.

 

Heavy rain here last night from 20:00 – 00:00 UTC

Hi All,

Further to my un-announced tests of QRPpp Op32 tests on the previous 2
nights, I will be running two consecutive beacon tests from about
20:00utc tonight.

My Class D Tx PA supply voltage will be 2.5 volts (about 2 watts DC
input) & the ERP is estimated at 100µW from my 10 m vertical antenna.

Reports & decodes will be welcome.

73, Gary - G4WGT.
