There are two big ham radio clubs around here, and smaller ones in

The hams can be very helpful if properly approached. Much depends on
the available time, talent, experience, and hardware.

BTW, the two stations I mentioned are HD, so Jeff, maybe that's why
they get the noise. So is 88.1, which is very close to 88.5 of
course, but 88.1 is a local station, not 45 miles away, so maybe its
signal is too strong for this interference to interfere????

I can't tell from here. The problem is that the occupied bandwidth of
an FM station with HD1 and HD2 sub-carriers is more than the assigned
bandwidth:

Just read the first two sections, as the rest is all about fixing the
resultant noise.

Reminder: Please make an MP3 sound clip of the noises.

That will take me some time. I first have to find my Sanza Chip, or
Clip,or whatever it's called. It does record iirc. I've been sort
of looking for it for months, but now I have a reason to look harder.

The radio next to the computer has reception problems with these
stations, so the noise is muffled and only recognizeable because I
heard it on the other radios. Tonight I tried to fix up two AM/FM
clock radios, but only got the AM working on each.

I also have a 40 year old cassette recorder that probably works fine,
unless it doesn't I guess I coudl use that and then play it for the
computer mike. (I have a great computer mike. )

I'll check these all out.

Hint: Assumption is the mother of all screwups. Test your theories
and guesswork, even if you think it's improbable. I've been wrong and
surprised more times than I can comfortably admit. That's one reason
my domain is called LearnByDestroying.

LOL. Okay. I'll do my best.
