Is there any wind when this is happening? Perhaps you have a fluttering
wire.

> There are two ordinary wooden "telephone" poles in my neighborhood

> this loud hum. Oddly these two noisy poles are separated by a non-humming
> pole, that is, there is a humming pole, 150 feet or so later there is a
> quiet pole and 150 feet later a noisy pole.
> These poles sometimes hum and sometimes not. I don't detect any RFI
