I'm embarrassed to admit that I had overlooked a noise-maker in my
shack, my 1 TB USB disk drive. I cleaned that up with a few turns of
the DC power cable around a type 31 toroid, and now I've uncovered
something under it. It's a wideband signal (tuning makes no
difference), but sounds very much like a badly distorted broadcast station.
Just on a hunch, I tried tuning across the AM broadcast band, and found
a loud AM sports radio station on 1570 KHz that appears to be
broadcasting the same content - pauses, pitch of voices, etc. all seem
to match.. Unfortunately, just before I could get set up to record, the
voices on 160 suddenly went away. I'm assuming they'll be back, and
while I wait to get a recording I'm wondering:
* Does this sound like intermod, or some other phenomenon?
* Is it the result of something wrong at the station?
* If so, how best to approach them about it?
