I've been tuning across HF and I just realized that the weird noises
that are obscuring 6055 are EVERYWHERE, on every band, not only on my
FRG8800 but also my DX396 (battery operated/whip antenna, so it's not
line noise). I turned off and unplugged everything I could think of,
from air cleaners to lights to computer equipment and it's still there.

I"ve no idea of your physical environment, but I'd try using the
DX396 on batteries as a direction finder to see if you can locate the
source. Try it first with a strong local MW station to get a feel for
the directional characteristics of the DX396. Usually if you collapse
the whip antenna there is a ferrite stick inside which gives a pretty
clear null off the flat side of the radio. Then try to use it to find
the direction of the noise source by listening and nulling from a couple
different locations.

Naturally, I found that when placed next to my computer the radio makes
a noise that sounds a lot like a data transmission. The weird part is
that unplugging the computer doesn't eliminate the noise.
