just to see if it worked, I put an RF choke around the wires going to/from the tstat. So far I haven't had the problem reoccur. I just used a 2 part iron core choke I got at radio shack and wrapped as much of the wire around it as I could.
So far so good. I would be curious to see the filter that the tech installed in John C's coach...
