 Most new radios have this feature Jeff. Back when there was just
Fast AGC or No AGC we used AGC on AM phone and No AGC
on CW.   This was back in the 1950's when you had a transmitter in
one box, and a receiver bought seperate, or once in my life built for
myself.

    Today because I'm very old I do CW either with Slow or No AGC.
When you use No AGC you turn the RF gain to zero, turn the audio
gain to full  On, and then slowly increase the RF gain until you hear it
as you want it. This method has a lot of plus features. It makes your
bandpass filter work better, and your wife will insist you use earphones 
:-)

    Fast AGC is for AM phone stations.
