[Elecraft] KAF2 v. KDSP2

[Don Wilhelm]

Howard,

I can't speak for anyone else, but I just don't like the sound of any audio
DSP processor, particularly for CW use.  They are good for digging signals
out very close to the noise level, but my ears find the KAF2 far less
irritating for extended operating periods.

It is more a matter of personal preference - the KDSP2 users seem to be
quite happy with it, and I have built several for other hams, so I have had
opportunity to listen to both on a bit more than a casual basis.  For mostly
SSB operation I can recommend the KDSP2 for no other reason than the noise
reduction, but I personally find I can do without it.  Each to his own - if
you could listen to both before making up your mind you can make a better
decision.  With the KDSP2 you can adjust the parameters to alter the sound,
but chosing the 'correct' ones for your ears may take a while and a lot of
trial and error.

73,

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).
