Hello Jay, Thank you! I have increased the bandwidth to 2500 Hz now. It will be interesting to find if there will be substantial difference. 73, Roelof, pa0rdt
My receiver bandwidth is 540 Hz. It has been shown in the past that a receiver bandwidth significatly less than 2500 Hz artificially inflates the reported WSPR s/n. Jay W1VD WD2XNS WE2XGR/2 Hello all
