[RFI] Ensuring an RFI free air conditioner install

[K9MA]

FWIW, I've had two Bryant furnaces (not A/C) with variable speed fan 
motors and the associated electronics. Neither has had any RFI issues, 
in either direction. My gas water heater, however, died every time I got 
on 160 before I added a bunch of filters to the power cord. Cold showers 
after contests are not good for relations with my YL.

73,
