Topband: RF noise

[Herb Schoenbohm]

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.
