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.
