380 Hz would seem to rule out any BC station. Sounds like what someone might
do in my immediate neighborhood when I was in HS over 40 years ago - Putting
500 W AM on 840 into an end-fed 200 ft antenna and wiping out WHAS reception
in Milwaukee. Could be a pirate w/o any programming. A little power goes a
long way on 660.

QSB could occur when a low horizontal antenna with high vertical angles of
radiation clash with the ground wave. So the source might be fairly close.
Especially near dawn or sunset.

It wasn't there this morning (Fri). I didn't hear any modulation at all (it
would have been obvious with a 380 Hz offset).
