I work in the 2 to 3 db above the noise floor CW, and 6 to 10 db above the noise floor on SSB now, (that is why I presently own a K3s and a P3VGA) so I guess I will have to wait for the real answer. I really cannot believe that Elecraft did not run their own test. If and when I spend my cash I am not looking for the pretty blinkie colored lights and a fancy screen, I want performance. My really big issue is: receiver noise floor, sensitivity and DSP that does not distort or degrade the incoming signal. But thank all of you for your input and I truly appreciate all the comments.
