    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.
