Just a quick note on using the KDSP2 filtering --
For best overall operating (especially in crowded band conditions), it
is always better to use XFIL to narrow the IF filter first, then use
AFIL to add the KDSP2 filtering if necessary.
That keeps the level of strong adjacent signals to a minimum and
prevents overload of the AGC (and the resulting receiver de-sense).
I do see several operators who use only the DSP filtering, leaving the
preceding IF bandwidth 'wide open' - not the best way when the bands are
crowded.

You might want to look at the KDSP2 manual
http://www.elecraft.com/manual/KDSP2_A1.pdf How to operate it starts
on p. 23 or so.
Once it's set up, I'd not want to use my K2 without it.
