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.

"AC Power Interference Handbook" [
http://www.arrl.org/shop/AC-Power-Interference-Handbook ] also uses similar
language. The ARRL RFI Book says "A sustained spark is often called an
'arc'." Then they also refer to power line RFI as "spark-type"
interference.
