Not sure if I’m posting this in the right place. I need some assistance with quelling some RFI. I have a god awful consistent S9 on 40m and have tracked down a few culprits. I know what needs to be done to reduce the RFI but I’m having difficulty figuring out what exactly I need to do this. I’m guessing a Mix 31 is what I need but I’m lost beyond that. I have a TV and a cable modem that are the cause of a lot of noise when I did a test for RFI with my SW receiver. Should I be using toroids or snap beads? How many and what size, and where do I get them at a reasonable cost? Thanks in advance and 73!
