[Elecraft] [K3] High internal noise level

[Pete Smith]

Ever since I got my K3, I have been a little surprised at what seems to 
be a relatively high noise level with no antenna connected (or on a 
dummy load).  Very unscientifically described, on 20m it registers 1-2 
bars on the S meter, and the background is quite loud on the speaker 
with the audio gain set at 12 o'clock (RF gain full, AGC - fast, 
bandwidth 200Hz with a 500 Hz roofing filter in, no noise blanker or 
noise reduction).

The radio seems to perform fine, and I have not had the feeling that I 
was missing many signals because they were being masked by receiver 
noise.  Nonetheless, I wonder how this compares with others' experience, 
or with the factory expectation?
