[Elecraft] K2 Kit Questions

[K1FFX]

I can share my recent experience in the ARRL CW DX contest.

I have a K2/100 with no additional filtering (i.e., no KAF2 or KDSP2).  I
had
the variable bandwidth crystal filter set to 1000 Hz, 500 Hz, 300 Hz, and
150 Hz.
I ran most of the contest set to 150 Hz.

There were a few times when I felt like additional filtering would have been
a "nice to have".  There were no times when I felt like it was a "gotta
have".

And that was also my experience in the CQ WW last November (running 10
watts pre-KPA100!).

I'm probably going to build the AF1 external audio filter later this year. 
I'm
sure it will be handy, but I'd do it mostly for the pleasure of building
another
mini-module!

Cheers -

Bruce
