[Elecraft] K3 AGC and Apparent Noise and Signal Distortion

[Lance Wilson]

Julian, You could be right and I did not express myself well in my post. When
I said that the AGC threshold was ineffectual I did mean between THR = 2 and
8. Perhaps a solution would be to do as you suggest (with a few others) and
simply raise the available threshold settings in the CONFIG menu of the K3.

Indeed, activating the attenuator does improve the situation quite a bit but
as I operate 20M and above for the most part I do not want to operate the K3
with ATT on all of the time.

One other characteristic of my K3 is that although varying the AGC threshold
does change the audio (and consequently the noise also) level the S-meter
stays at the high S6 to S7 levels. The metering circuit seems to be
independent of this setting. That in itself is not a huge issue but it seems
that something else is involved here.
