[Elecraft] OT Mystery QRM Help (Video)

[Ken G Kopp]

Hi Dave!

In a past life I was a noise technician for a large electric utility.....

WAG's:

Solar cell controlled street light.  Had one a block away about a year
ago.  Came on dimly and slowly got to normal brightness and noise
diminished as got brighter.

Is your area cold enough that someone has placed a heat tape in an eve
trough or downspout?

A timer or photo cell controlled flood light that might not be making good
contact in some manner?

Electrically heated floor?  Once hosted in a state park that had yurts with
electrically heated floor tiles.

Touch lamps are notorious noise sources.

On-demand water heater that is activated when someone gets home from work.

Are there any heated critter drinking pans or tanks nearby?  How about a
hot pad or electric blanket in a dog house?  Had one next door some years
ago.

A neighbor with grow lights?  A heated bed for plants in a green house?

The possibilities are infinite ....

73!
