Re: 6m RX and 4m TX WSPR


Hi Mike,
I often run my U3S 4m Tx and Rx system on WSPR but it is a very lonely band as you say. I have managed to boost my OCXO controlled Tx to 1 Watt using a modified QRPlabs '5Watt' PA, and boosted the Rx sensitivity by using a homebrew 4m to 28m converter to U3S Rx and a Raspi doing the decoding. Antenna is a horiz half wave dipole in the attic.Just to add to the confusion there seems to be two WSPR operating frequencies for 4m so I run on both of them!

I'll look out for you.
