[RFI] RFI, Power Company.

[Pete Smith N4ZR]

I have Marv Loftness'sAC Power Interference Manual  Manual, and it makes 
it clear that sparking can cause RFI, as can arcing. He gives as an 
example of sparking loose hardware tying an insulator to a crossbar.  
The worst RFI I ever had resulted when a woodpecker undermined one of 
two lag bolts holding a lightning arrestor to a pole, causing sparking 
between the bracket and the loose bolt.
