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?? Rich K8JX Visit our club at http://www.w8usa.org Rich and the cat Scooter www.foreverhomesamoyed.org www.w8usa.org "The easiest thing in the world to be is you.
