[Elecraft] [K3] Attenuator and soundcard digital modes

[ik1bxn]

Even if my name is not Don...HI I'm posting the way I use to work psk31.
normally I keep 2700 Hz bandwith in order to have the waterfall at a glance.
Then if ther's a track that I want insulate from the rest of the world (for
example because it's a weak trace or there's a very close strong track) I
move the filter center to the frequency of the track I want to follow
(inside the 50 Hz granularity of course) and then I reduce the filter
bandwidth to 100-150 Hz (the k3 automatically switches to my 400 Hz 8 pole
filter).Sometimes at that point I switch on the Pre. I use normally 40w
power in DATA-A mode.73 to everybody-Giorgio
