Dave :
Thanks for asking this question. As a K2 owner with the KAF2 installed, I have
also often wondered what I am missing out on
by not having the KDSP2 installed instead. From the responses to your
question, the consensus seems to be that it is well worth the upgrade
if you primarily

Yes and the K2 is still a very competitive rig,
even after 16 years, Michael! I now have the K3
and a KX3, but given all the TLC that I put into
building the original (#380) K2

David,
The KAF2 is mainly for CW use. It provides a great peaking filter at
the frequency that you have set it to (presumably your sidetone pitch).
It also has a low pass filter that is in-circuit at all times. That can
reduce band noise hiss for all modes.
The KDSP2 also provides
When I built my K2 a year and a half ago, I also had to decide between bare K2
vs KAF2 vs KDSP2, and went through the archives. In the end I went with the
KDSP2, but some of the points I considered along the way:
Bare K2:
- built-in IF filters do work very well, but I read some reports that
David,
My K2 is long gone, but I can tell you about my experience with the DSP module.
I operate mainly CW, and added the DSP option after having the K2 for over a
year. For me, it was a mistake. The radio didn't sound as good as it did before
adding it. I wound up taking it out and selling
I thought it was. A bit complicated to get
adjusted just right, but there is/was a how-to doc
at the Elecraft website which you might want to
read, David.
I say "thought" because now I use my K3 and KX3,
though I still have my all-up K2; it's a keeper at
this point.

I would not have upgraded to the KDSP2. Not for the performance, because
although I'm mainly a CW operator, I could probably benefit from it.
My main objection to the KDSP2 is user interface. The K2 was not designed
for the KDSP2 in the first place as can be seen in how complicated it is to
set
Definitely true re user interface. But if you get
it set up in a way that works well for you, then
not much need to tweak.
I don't often change settings in my K3 DSP either.
