[Elecraft] RF gain sweet spot

[K7WIA]

No I don't believe there is a problem with the pot.  because as I just start
to turn it the gain reduces smoothly all the way.   I believe it could be in
the software, where as when the gain is reduced the ckt. that controls the
bars in the S meter does not kick in soon enough. 
but it seams when I reduce the gain to where the ant. noise gets close to
-136 dbm ( the noise floor of the K3) that is where I can detect the weak
ones the best. It is just that my  ears and brain seam to be more sensitive
when the audio is soft than when it is loud, as when there is a lot of noise
with the signal. it is just that I reduce the ant. noise close to the noise
floor of the K3, the signals are still there and they stand out better for
me... it's just that I started to use the old trick that been around for
years, and noticed the S meter did not follow the gain control.
