Try some choke's or ferrit beads across your coax cables, your
TV input cables and Radio control cables. You can buy them
at a Radio Shack store if you still have one around you, some
but not many are still around but not many.
I would also also check to make sure your coax connectors are
not duty and tight.
Make sure your jumpers between the radio and tuner or
amp are all good, one bad apple can generate lots of RF.
I check my jumper against a dummy load with my analyzer
before installing them. even then after a few months I have
found one to go bad.
Mr. Murphy has way to make a HAM pull out his or her hair
tracking down RF problems.
