Analog AGC which CANNOT be turned off since it is
ALWAYS ON to protect overdriving the DSP's ADC with
signals stronger than ~S9+30.

        Oops, that level is actually closer to S9+40:

"That means a receiver can handle signals from the noise floor to almost 40 
dB over S9 without analog AGC. Above that level, analog AGC is still 
necessary to maintain the linearity of analog circuits and to prevent 
overload in the ADC hardware."
