[Elecraft] [OT] Interference from HVAC equipment

[Erik Basilier]

The recent discussion about interference from Plasma TV sets, while not
directly related to Elecraft products, caught my eye as very relevant to
many hams. Perhaps then a discussion of another potential interference
source might be of general interest. Our house furnace and air conditioner
equipment is quite old, and will need to be replaced in the not too distant
future. It doesn't generate noticeable interference, but then none of the
motors involved have continuously variable speeds. Newer, energy-saving
equipment seems often to rely on variable speeds; this suggests to me a
source of potential interference. I'd like to hear about what brands and
models might or might not cause interference, and what you might have done
to fix it.

 

Thanks in advance,
