Hi All,
               I've had it with window AC units and have decided on a mini split system.  Guy came out today and took measurements and I asked him about RFI complaints from previous installs.  When he told me about the inverter powered variable speed compressor, I thought.......inverter>>>>square waves>>>>>harmonics>>>>>RFI.  He told me they did one installation in a house owned by a ham op, and had no RFI problems.

               Anyone have a MITSUBISHI mini split system?  Any RFI problems, especially on HF?  Thanks for your time!

get the other guy's phone number from the installer and check his references.  there is no substitute for talking to the guy that has one.

           That's why I posted my question here.........someone here must have one of these systems, they are quite popular.  Companies may be  reluctant to give out their customers personal info, that's why I didn't ask.

 I am a hvac installer in portland or. I have been to a few classes and all the reps in these classes say anything within 10 feet of indoor or outdoor unit
may get rfi. The good news is they are very quiet and compact. I have put in all brands and Daikin ductless seems to be the bullet prof one. I would put it in your contract that if units interferes with your station they need to fix it or give money back. Also with the r 410 refrigerant it is very important that the person installing a system uses proper refer procedures.

good luck   w7akv
