Be careful with the new LG linear compressor refrigerators. Mine outputs
low level spurs every 2 kHz on 40m Obviously, noise level is a function of
orientation between the appliance, antenna and if used, ladder or open
feeder lines. The main radiating source comes from the CPU/Display. The
root noise may, or may not have anything to do with the linear compressor.
Once I get my hands on disassembly instructions I'm going in - warranty or
voided warranty.
In the U.S., we *really* need an amended Part 95 to include unintentional
radiation from appliances and all sub-assemblies used within an appliance.

RFI revisited
I have a one year old LG front loader. Quiet as a mouse and it has a
variable speed drive too.

Been shopping for new washing machine after our very old (and RF quiet)
Maytag washer is having problems once again.
RFI archives summary seem to show the following brands have historically
been good and RF quite: LG, Samsung, some Kenmore (if not made by Maytag
or
Whirlpool), and the old fashioned Speed Queen which is the last of the
non-electronic, old agitator models but are hard to find in stock and
cost
as much as the newer technology.
Bad or RF noisy washers were: Maytag Bravos and Neptune, Whirlpool Duet ,
Kenmore Oasis HE, GE Profile Harmony, and the Gibson.
The older models given for quiet LG are no longer available (WM0642;
Tronn:
WM2277HW). Newer models start with WT (WT4870CW & WT5070CW) under the
boring technology/names "Inverter Direct Drive" and "Wave Force". Older
quiet Samsung model was WF218ANW.
Does anyone have any recent RFI experience with the newer LG (model
WT####CW) or Samsung models?
