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...
anyone tried contacting one of them for assistance in finding & shutting
the offending repeater?
