S6 line noise

KB4OIF

Good afternoon.   have read the manual a few times and the section about mitigating noise.  I have toroid cores on all my lines.  I have a constant S6 line noise.  I live in a subdivision that  has overhead lines.  Took my am radio up and down the street and found no buzzing.  I have a few wall warts in the shack but none of them seem to be buzzing.  I held the radio up to my all in one PC monitor and it buzzed like crazy.  Turned the monitor off but still have the noise.

I went to your qrz page and saw  you are using 2 antennas that are prone to noise . I good rule of thumb on the antennas you are using is to decouple the feedlines at the shack end and to use a coax switch that shorts and grounds the unused feedline .  Alpha delta 2 pos or 4 pos are awesome. Balun designs sells a real nice coax choke for the feed line decoupling  you will need one for every feedline that comes into the radio room. its not a one and done but when you have the noise under control ham radio will be more fun for you
