There is one

is being rectified, and the rest just seem random in
nature. I thought
it might have been SCR noise but it doesn't follow any
kind of logical
pattern. The Hammarlund's noise limiter chops the main
spike but thinks
the rest is a legitimate signal.
This can be just about anything, including SCRs,
switching supplies, and
arcing.
All you can do, once you have established that it isn't
your house, is to
get a handheld AM radio and use the loopstick to try and
DF it. The problem
is that the junk gets into power lines and then radiates
from there, so
it can seem to be coming from everywhere at times.
It's amazing how much trash one touch lamp can put out.

Well,
I do have a marine RDF, but I can't find it under my piles
of stuff, radios, car parts, more 'stuff'.
When I find it I will be out looking around.

Its salutary for collectors of stuff to read about the
Collyer brothers. A good account can be found at:

Electrical noise is a PITA in spades, doubled.

Wow.
I can't top that. That was a bit of an amazing story though.
I have lot of turn of the century National Geographics but nowhere near
what they did. There are a lot of radio parts, lots of books, both mine
and my daughters. Probably half of what I have is of no value, but I do
have some vintage test equipment and some older radios of the tube type.
