Chasing RFI can be a bit like Sherlock Holmes detective work. Think 
of what equipment might have been purchased (or received as a gift) 
at Christmas and used during the evening. Some common RFI sources 
include electric blankets, TV sets, battery chargers of all sorts 
(for power tools, golf carts, etc.), switching power supplies for 
low voltage lighting.
