Lee you might check the AM band and see if there is a detectable carrier 
on 603.6 or 905 Khz as sometimes unlicensed AM pirate stations try to 
slip in between the noram AM 10 KHz increments to avid interference.  I 
could be one such station's second or third harmonic with the carrier 
just left on. These transmitters are more and more common and available 
over the internet from overseas.  The have frequency synthesizers with 
1KHz increments and their output stages are as broad as a barn with no 
harmonic protection at all.  It would be easy to see with a car radio or 
even with your home station, if there is any junk on these frequencies
