Ed,
You bring up an interesting point...
When Peter Martinez (?) co-invented PSK31, his software received a
single station at a time, tuning was critical and you could crank in
your 250 Hz filter (or the best you had).
Then along came Digipan et al, with the waterfall display. The good news
was, you could tune by pointing and clicking. The bad news was, because
most people used their widest filter (2.8 kHz), any strong signal in the
pass band would operate the AVC and usually drop the weaker signals off
the edge of the earth.
In your original post, you ask "why in the world would you select a 2
kHz bandwidth?".
I guess that because it's cool to see multiple stations and to be able
to point and click and that apparently was the main point of the
software-to eliminate critical tuning. From your post, the implication
is that you *don't* use a wide bandwidth. Could you please elaborate?
What bandwidth do you use? Any special/different tuning techniques? (Of
course, these questions assume you are using a Digipan-like waterfall
program, not the Martinez original).
Inquiring minds want to know...
