[Elecraft] KAF2 v. KDSP2

[js]

Hi Howard,

I built both KAF2 and KDSP2 for a number of hams.  Having the chances of
comparing both of them, my views are as follows:

1.  There is a substantial price difference between KAF2 and KDSP2.
2. For CW reception, KAF2 performs not much worse than KDSP2 BUT the noise
reduction in KDSP2 will lessen the listening fatigue.  Of course, there are
always individuals who do not like the digital sound.  However, I find the
noise reduction of KDSP2 is in line with my IC756pro2.
3. For SSB reception, KDSP2 is well more useful than KAF2.  I understand you
may not  be interested in SSB BUT the inclusion of SSB in K2 makes the rig
complete.  For example, when  you drive a Mercedes, you may wish to have
alloy wheels or even AMG accessories as a completion.  In this respect,
KDSP2 is a good choice.

Therefore, you choices may depend on:

1. cost concern;
2. the chance of using SSB in your operation

I am planning on purchasing a K2 for general use (SSB and CW) with a current
preference for CW.  (I enjoy working on CW although I'm not very good.)  My
preferences may change as my experience grows, so flexibility is important.
The question is, why would you want to have the KAF2 instead of the KDSP2?
>From querying the archives, it seems that the KAF2 is primarily used for CW
and is effective for that use.  Is the KDSP2 less effective for reducing
unwanted noise on CW, or is it equally effective but more costly.  I assume
that Elecraft continues to sell the KAF2 because it either has a performance
advantage in some niche or is less costly and works for certain uses (such
as CW).

Thanks for the advice,
