I said this before and I will say this again. Rob Sherwood agrees with
me on this. And I know I am going to get beat up on this but I'm tired
of hearing wrong things about RF gain.
RF gain has absolutely no effect on signal to noise ratio. Reducing RF
gain reduces the noise. But it also reduces the signal in the same
proportion. It is useful to reduce the RF gain in situations where the
signal is much higher than the noise so that noise is not heard in
between transmissions. But to hear the very weakest signals, the RF
gain must be high enough to hear some noise.

The answer is a resounding YES. The implementation of the RF Gain, as it
is integrated with the AGC system, makes for effective performance with
regard to signal vs. noise.

Bob, K4TAX,
One of the features I always liked about the Omni VII was its broadly
tuned RF gain which had the ability to reduce noise while appearing to
enhance or maintain the signal you are trying to hear. In your opinion
does the Eagle's RF gain function similarly? Most RF gains including
K3's reduce noise and signal and do it at the maximum nearly fully
clockwise position.
