[RFI] Peculiar Noise

[k1ttt.dave at gmail.com]

I tracked down a noise like that many years ago to a tv preamp on an
external antenna, would wander up and down the band but occasionally liked
to park on a local repeater input.... first step is to find it, then figure
out what it is!

Anyone care to make a guess at this ?

I have flipped the main breaker and turned off all UPS's in the house.
Peaks SW, which is towards a neighborhood over a mile away, and a large
copper mine, 2 miles away. There is also a line of 14.4 kV power lines in
that direction.

It will be on for several hours at a time, then disappear. Nothing else like
it between 40 and 60 MHz. I would never have noticed it, except it sometimes
parks itself on 50313, the 6 meter FT8 frequency.
