What antenna changes or coax changes (lengths, runs, etc.) have you done recently? Are all of your antennas properly isolated with common mode chokes? Are your antennas resonant dipoles? (OCF’s, etc. can be problematic with RFI.) Have you changed anything in your grounding scheme? If you didn’t have this before, look to any changes you made first.

Yes understand low SWR still can cause RF in the shack. I am trying to track down, but not that simple to find. I believe that is the issue but finding it is almost overwhelming, especially since the same computers and radios never had this before.
