[Elecraft] K3: ducking this topic

[Erik N Basilier]

Douglas,

To avoid bringing down the audio level of the station you are working,
again, the "ducking" might be better done by automatic change of
bandwidth instead of automatic change of gain setting:

I would be listening around the band with, say 500 Hz, find a station, use 
e.g. CWT to tune properly.
As soon as I call him, my receive bandwidth automatically drops to 100 Hz, 
and stays there until
say 1 second has passed without any transmission from me; then the bandwidth 
widens to 500 Hz again
until I transmit again. Saves the trouble of manual action. If instead I was 
calling CQ, I may or may
not prefer this mode, as it would make me hear the correctly tuned caller 
before I can hear ones
that are off frequency.

73,
Erik K7TV
