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
