[Elecraft] Help identifying this RFI

[Reed]

I heard that exact noise before Wes.  I went up and down street & 
grabbed the guy wire going to electrical poles while shacking the pole I 
found an insulator arching. Tracked it down with mobile rig in car.  
Gave power company the pole number and had it fixed within a week.  Like 
the idea of waiting until dark to see the arching.  Might be faster 
doing that, but that noise is one I will always remember.

Now if I could just get noise out of Rheem heat pump coming from 
blower.  Got external fan noise fixed with torrid core coils.  Stay away 
with heat pumps that use d.c. motors!
