Hi Tom and Group,

I recommend you buy a copy of the "Interference Handbook" by William R.
Nelson,
WA6FQG.  (Nelson was a RFI Investigator for Southern California Edison!) 
The book
is published by Radio Publications, Inc. - have seen new copies for sale at
hamfests.
Contains lots of tips.....as you know it's not easy finding the real
source.

73,

John  W0DC
