[RFI] Chasing RFI

[qrv at kd4e.com]

Charlie,

	It's not always visible but failed lightning arrestors are a
frequent source of trouble.

	Have you tried looking at the pole using a telescopic camera
lens?

	If you can spot a deteriorating arrestor or something
sparking - then report that with a photo - you will be doing them
a favor.

	Things "always" seem to fail at 2am on a weekend = overtime
cost and hassle.

	The latter is per our local electrical Coop.

Just one thought ...
