houses - the 72 cent silent variety - would radiate as you describe while
they were switched off(!). I had 2 distinct peaks that sounded like what

Recently, the state highway people installed temporary lights at a road

the lights themselves, and I surmised that it might be using radio at some
frequency to sense the presence of cars waiting for the light.
