Help with 4 kc wide 80 & 40 meter signals, possible RFI
Any suggestions or experience with the origin of these 4 kc wide signals on 80 & 40 meters? They all sometimes shift 1-2 kc. I have common mode choke on my antenna and ferrites on all transceiver inputs and output wires, coax and power cables.
