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
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.
