Hi gang,
The K2 is the first rig I've had that has adjustable AGC. Under what
conditions would one benefit from using fast AGC? It seems that slow AGC is
easier on the ears on CW.
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.
