Hi Don,
You might want to refer the people working on the problem to this Power
Point for a tutorial workshop that I've taught to pro audio and video
people. The principles are no different when the interference is at RF.

Henry Ott's excellent text on EMC includes a sub-chapter on these very
nasty RFI sources. His book is widely used as an EE text, and considered
"the EMC bible."
