There's some huge heterodyne 380 Hz off 660 KHz in Central Ohio
this morning (5:30am EST)

Any idea what it is, or where it comes from?

Seems to be from the East or West but I'm not sure yet, as I also
null the desired station WFAN 660 when I null the east.

It seems to be at 660.380 kHz (above rather than below 660)

Not heard here at 1150.

It might be an Art Bell UFO.I did a www.devilfinder.com for,Huge
380 heterodyne hz carrier wave in Ohio

It probally won't shed any light on it though.Strange things do happen
in Ohio sometimes.

Probably something very local. I heard something similar the other day
while driving to work (I think I was listening to WFAN 660 as a matter
of fact). After driving a couple of blocks the heterodyne faded out.
The het I heard was a more like 1,000 Hz.

Do you have any idea as to its bearing? A signal that strong should be easy
to DF.

It was probably either E or W pretty close, just from taking a portable radio
outside and nulling the het without nulling WFAN (WFAN is also nearly east).

I'm sure I have a recording, ...

It was startlingly strong, but then so is WFAN in Ohio.

I got rid of it with antenna null steering and 3 cascaded notch filters,
and didn't experiment much with the real equiptment after that; just a portable
radio in the yard while the recording went on inside.

My impression was that it faded later but I wasn't listening continuously to it.
Fading would suggest it's not local. If it's there Friday I'll try to record
it on its own (rather than suppressing it).

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.

A pirate or somebody "tuning up" his or her radio.I think your
explanation sounds as good as any,Gary

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).
