[RFI] RFI in the HF spectrum from variable speed Mitsubishi HVAC systems

[D C _Mac_ Macdonald]

I have a local ham friend who has a Mitsu system.  If I recall, it is very close to his tower and I have asked him to comment on the RFI aspect. Since he is a pretty serious DXer and contester, I'm sure he would have complained loudly if there were a problem.

That will cause him to build the cost of adequate filtering and other measures into the cost.
