Sounds almost like work. The noise is worst at the lower frequencies but
still wreaks havoc with me even getting WWV at 10 MHz. There is one
permanent spike at the peaks of the power line, so it is something that
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.
