It could also be riding on the Governments Pave Paws, SADL, EPLS, and
other digital signals they transmit regularly. There are numerous areas
in the US where these signals are just transmitted in the Amateur Radio

Well if you can hear a commercial FM station coming through your repeater it
could be a spurious STL. We have chased down two different malfunctioning
STL's here in the last ten yrs that had spurs that would drift around across
several repeater frequencies.

The actual carrier is 145.25, which is cable channel 18. You would
hear a buzzing sound but only on the output, it wouldn't go through

What band? VHF, UHF, 220
I see from your club website that you are running braid/foil coax and RG-213 as
jumpers to the duplexer. You might want to consider a change to heliax for the
