[Elecraft] Quiet Ductless HVAC System

[Andy Durbin]

"Just as other appliances sold these days with a motor i.e. washing machines, dishwashers...  while digital control may add nice features, the noise generated can reduce operator pleasure (or operating hours)."

It's not a new problem.  My over 30 year old Maytag washing machine with crude mechanical sequencer is a horrible RFI generator.  Huge noise bursts with every motor run period.

I'm glad my 35 year old heat pump is still running.  It's single speed, all mechanical timing and control, and RF silent.    I have no problem turning off the washing machine to operate but turning off the AC is not really an option in Arizona.
