Hi Ron, What a great story- the soul of ham radio. I had similar similar
experiences. Fellow hams gave me stuff or sold it for little, just to give me
the experience of getting on the air. I hope that that still happens. I am

Hi, Doug!
Two questions...
What do you mean by "technical design technique"? Is this referring to
how the rigs were designed? Or is this a technical "feature" common to
all their rigs?
And you are suggesting this technique applies to every model of Elecraft
radios, from the K1 to the KX3?
Just a couple of points.
In the K3(S) there is no "RF Gain" control unless by RF gain you mean "It's not
the audio gain gain control."
The "RF" gain control operates on the i-f amplifier, which is after the analog
noise blanker. In this regard, it is little different from AGC, which operates
