Very impressive Niels, my 200uW ERP signal was Spotted 3 times last night.

Not my best DX on the band but that is 2,635000 Km, 1,635000 Miles per Watt of ERP to your 80m Longwire and SDR.

Unfortunately my indicated power level +17dBm 50mW is merely an arbitrary figure, hard coded as WSPR does not cope with the actual power.
