It would be a nice effect, but I don't see this on the low bands
although I just tried it on 15m. What I see is the S meter level
remaining constant until the RF Gain is reduced to the point that the
bars begin to rise above the band noise. What I am going to try is
setting the RF gain just at the point before the bar advance pas the
band noise.
As I have my S meter set for absolute, I am seeing about an S9 level on
the meter from the noise. I can reduce the RF gain until the next bar
is displayed and then back down just to where it goes out and the noise
level from the speaker is greatly reduced. I will see how things work
on a net in a few minutes. I don't see a visible dip, though.
I am at MCU 4.36, FPF 1.14, and DSP1 3.73, on K3 S/N 4762.
