[Elecraft] K3 PRE function question

[Doug Person]

That seems odd. I live in a community of about 2000 spread over an area 
of 450 square miles. There is power and phone service to every house. 
Internet is either satellite or over the cellular network. My noise 
level on 20 meters is less than S1 and usually doesn't even move the 
meter. 80 and 40 are typical of atmospheric conditions. Even on my 
full-size 40 meter vertical the noise level is typically S1 to S2.

You must just have some really bad luck. I think I live in a typical 
rural community where the only real noise generator is a cranky electric 
fence.
