Next time, turn the radio at various angles and see if you can
null the noise out. Usually the top edge of the radio points
at the direction it's nulling away, and outdoors that would be
pretty horizontal most of the time, but if it's coming from the
wires in your house as well, almost any angle might be the one
you need to try.

Practice nulling a weak station in the daytime. The same thing
works on noise sources.
