I'll attempt 3cm and 6cm SSB from home, for the January SHF UKAC. Will have KST, Zello and 144.390MHz SSB. Not holding out for many QSO's, but we shall see. Hopefully the snow will have melted by then

Are LEDs a noise source 27 messages
I have just built a G4DDK PGA-103 preamp to use for ADSB receive on 1090MHz. The preamp will be mounted up on a pole, directly underneath a PCB antenna, in a plastic tube. I feed 12V up to the preamp

Whitebox Oscillator Diode Replacement. 2 messages
I recently bought a whitebox system which arrived in a very poor state. The oscillator 1st stage had several burnt out resistors and the 2nd stage transformer was shorted. All these easily fixed. But
