Being placed in a "specific mode" more than likely means a nice square wave, just narrower than at full power.

I had the fan motor replaced in my HVAC unit with a motor that did not need "Inverter technology".

"Inverter Technology", will probably get you "RFI suppressing Technology" in your hamshack...

Ask to see one in use, and bring a portable SW radio, and some ferrites... I had a bit of noise on my setup, three or four ferrites later teh problem was solved, but I opted to not avail myself of the latest in "Inverter Technology". :)

73, and thanks,

It seems to have a variable speed motor with “inverter technology” but the HVAC company says it can be placed in a specific mode (low, med, high) rather than auto where it will stay fixed.

ANY variable speed motor is likely to be a source of nasty RFI.
