Hi Jeff:
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.
FAST (or OFF) AGC is the only setting is EVER use on CW!
If you only work the 'strong ones', then using SLOW AGC will work
well for you. However, if you work weak stations with SLOW AGC
enabled, you'll find that a strong nearby station can (and often
will) 'pump up' the AGC, thus REDUCING IF GAIN, to the point that the
weak station will either drop significantly in signal level, or
possibly completely disappear until the strong in-band signal is gone.
Additionally, using FAST or OFF AGC will give you a 'sharper
sounding' CW note, which can be more easily copied, especially at
higher speeds.
You'll have to ask a phone operator about using FAST/SLOW AGC on
SSB... I have little experience there... <G>
