I have track down the call sign that was being broadcasted on the sat. But that was not the offending source. The call that was being broadcasted is a UHF repeater. And they are broadcasting on a UHF freq. The problem is that someone is using a rogue repeater or a cross band mobile or both and they were link up to this UHF repeater. So every time this UHF repeater would key up it would key up this rouge unit and broadcast on the 145.880. I was able to key up this rogue repeater, but it had no IDer.

I contacted the sys oper on this UHF repeater and he assure me that he was operating on UHF and has been for several years. So I got on this UHF repeater and started asking if anyone or knew of anyone that was cross banding to this repeater. No one acknowledge that they were doing it.

Mysteriously this morning this rogue repeater is quiet. I don't know if the storms took it out last night. Or if the person heard us talking and realized what he was doing and shut it down.

I will monitor this rogue repeater freqs and if I hear it again, I will try and do some fox hunting because it isn't too far from my QTH.

There are 4 ARRL-affiliated radio clubs listed for the Louisville area... has anyone tried contacting one of them for assistance in finding & shutting down the offending repeater?
