I notice a similar peaking or reducing effect when I turn on the OUTSIDE
lights while using some (SCR controlled, switcher powered) track
lighting. This is due to changing the length of connected wiring that
radiates when something is switched in, that's all. The total appearance
and disappearance of the interference is convincing evidence for the
source being on a timer, and the times strongly suggest it's lighting
of some sort.

Hello Tony:Could your noise problem be related to a dusk to dawn

Hi Tim:
That's what I thought until I saw the noise shift when I turned the
light off in the shack. You can see what happens in the video:

The light is not the source of the noise because the noise continues
with the light unplugged. There are no florescent lights or touch
lamps in the house. I disconnected the only sensor lamp I have on the
house today and the noise was still there.
I guess the question is: why would the noise shift in frequency when I
turn a light switch on / off in my home if the noise is coming from an
outside source like a street lamp or a neighbors porch light?
Puzzling Tim...
Thanks
