Anybody know what the heck this could be? Recorded from a SDR in West Chester, OH.

The station it's wiping out is WHAS in Louisville, KY.  WHAS signal is strong enough here in the evening that racket is just a minor annoyance. It's been under WHAS for a good decade, on and off.

Nearby WLW in Cincy has it too, but it's much worse on their freq, where I'm at. I've often wondered given both stations locations close to Wright-Patterson AFB, if that's not where it originates at?

Personally, I think it's Gary Burbank in retirement in Florida getting revenge for all the times those two stations fired and rehired him. I wonder if his "Earl Pitts, Uhmerican!" bits are still being syndicated? IMO, Gary was the best drive time host I ever heard. He and his crew were anarchy in the booth.

Sounds like a good candidate for tdoa. Just rule out the known transmit sites and you have the culprit.

Just tuned there to see if I can get whas and no prob, I'm 70 miles from them. Also note they only seem to tx a bit over 5KHz of audio each side of the carrier for some reason.

I don't hear it the closer I get to the N. KY. area on trips. I put it down to signal strength that close in.

I'm still wondering if it's not a harmonic of a flight beacon intended for all the traffic in the crowded airspace in the N. KY./ Cincy-Dayton airspace going long?

It sounds like a distorted data sig to me, but how it gets emitted with enough power to cover ambc is beyond me. I was thinking it was a issue with ebs as ebs is connected to every bc station in the US, perhaps a glitch slipping onto the air.
