PSK31 newbie receiving problem (RFI in cable)
First thing would be some ferrite cores on the leads. RS has them.
Also, try an audio transformer in the RX audio line. A cheap 600 ohm
at RS will do. If that is indeed the problem, then even a temporary
setup should show a significant improvement. If it solves the
problem, it is easy to build one into a small box.
