[RFI] Fwd: RFI from Carrier Heat Pump?

[Charles Plunk]

Had a York 2 ton all in one (AC/Natural Gas heat) unit installed a year 
ago. Has variable speed motors. I dreaded the RFI possibility. At the 
time though other priorities necessitated getting one as quick as 
possible and nearly all I shopped for had variable speed motors.

Fast forward, no RFI detected from it. I could spit on it sitting here 
in the radio room if not for the outside wall :-). Only thing I hear on 
the rigs is when the natural gas ignitor kicks on for a second or so. 
Guess I got lucky.
