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
Spectrum (440 is the worse) and they mix with other sigs with
unpredictable results.

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.

Good morning on this soggy, Friday Morning.
We've been experiencing a recurring problem every once and a
while. It's not our repeater, but its driving me nuts trying to
figure it out. It sounds like badly tuned can's, somehow feeding
the output back into the input. Except, it isn't from our
repeater. And it covers a wide area. I've heard another repeater
being bothered by this and also a local commercial FM broadcaster
came through. If I turn our repeater off, it's still there. ( I
said I was trying anything.)
Do you guys think trying to use direction finding equipment might
produce some results??
Oh, this noise is so strong, even my signal at 25watts at a
distance of 4 miles won't trigger the repeater!
Any ideas??
Suggestions??
