We have a 4 yr old LG that has not made a peep on any of the HF bands.

Hmmm... This is a bit worrisome. We are replacing our current refrigerator with
a new Kemore Elite (aka LG) unit. We have an LG front loading washing machine
and dryer and both are RF quiet. Anyone know about LG?

Bill, The sort of problem that Mel described from the variable speed control, I
had with a new A/C air handler that was installed her about 5 years ago in
Palmetto. I ended up having to the replace the brand new fan motor with a
single speed unit and all went fine after that. (Less energy efficient no
doubt.)
We bought what we think was a great G/E Profile series refrigerator two
years ago..no noise whatsoever. Though a refrigerator (or any appliance) on
sale may save you $$, the grief that you may get from it later certainly would
not be worth the savings. I would buy one only with an agreement that if an rfi
problem occurs within a given amount of time, that the unit could be returned
or exchanged. -Mike, K4CVL

Unplugging the refrigerator for a 48 hour contest would not make my XYL
very happy and I would certainly miss the cold beer afterwards.

Not sure if it was my review or not, but our 2011 Samsung two door low
energy refrigerator is horrible for RFI. When Samsung USA played dumb and
said that they could do nothing about it, I voided the warranty and
installed common mode and differential chokes INSIDE the casing. Did not
help. I added more common mode choke on the power line outside with no
effect.
The culprit is not the compressor but the compressor speed control that
creates variable frequency AC .... it's no doubt a square wave generator.
Sniffing the case shows the most RFI coming from the front panel near the
ice maker. When it runs, all HF bands have hash with shaprt spikes every 5
KHz.
a cheaper unit with a bit more compressor noise and only ONE speed would
likely not have the variable speed feature..... and may be RF quiet
We also have a Samsung LED TV that likes to turn itself on whenever I am
on 80 meters.... not enough shielding (also tried common mode on this one)
For this reason I will not buy Samsung, and find no problem with Sony
electronics in the same area of the house.
(In both units I unplug them when I am on the air. My wife hates it when I
am in a 2 day contest.)
