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

[Jeff Stevens]

Last summer I had an MUZ-FE18NA installed.  My antenna, a delta loop
cut for 40m, is located about 50' from the outdoor unit and 30 feet
from the indoor unit.  I'm a casual operator and have not noticed
anything above the noise floor that I can attribute to the heat pump
with that setup.  In order to hear noise on my receiver I've had to
take an antenna to within inches of the unit.
