Jim, It could be a photo cell switch as they are used all over the place now for solar lighting as well as street lights. If the problem as you described occurs with sunset and goes away when the sun comes up, it could give some indication that it is operated by daylight or lack of it.

Around 5 pm here as it starts getting dark there is some kind of interference
and wonder if anyone recognizes it ?
It sounds like your mom's first washing machine...Swish Swish Swish etc...
at a 2 Swishes in less than 2 seconds rate.
It sounds like Swish modulated static but softer sounding than static peaking over
S-9 at mid Swish.
Thank you, Jim / W1FMR. _______________________________________________
