[Elecraft] [K3] Differences in RF gain with and without AGC

[Ignacy]

In my K3 RF gain works as expected when AGC is off. Turning the knob so that
S-meter shows S4 reduces the background noise dramatically.

With AGC on, RF Gain needs to be turned off much stronger for the same
effect (S9+40). 

Is this just an abnormality on my K3 or is K3 programmed this way? It seems
that RF Gain with AGC on acts mainly on the front-end but retains white
noise generated in the latter stages.

If this is true, it would l explain why K3 sounds noisy with AGC on, but not
so with AGC off and RF gain adjusted as needed.
