Hi Guys, I've seen posts where some Air Conditioners and Furnace units with variable speed motors create RFI on the Ham Bands. I'm thinking of purchasing a new Carrier 3.5 ton Heat Pump, Model 25SCA542, with a "fixed speed" blower and am wondering if anyone has had RFI issues with these? Thank You in advance for your thoughts. 73, Dick- K9OM (RLVZ at aol.com)
