K2 options KDSP2 & KAF2

[N5SM]

Hi
I just received the KAF2  and the KDSP2 options for my K2 from the xyl as
birthday presents (73rd).
I notice that both options have the real time clock. My question is what
does the KAF2 option do
that the KDSP2 option doesn't do? Or, is there any reason to have both
installed ?
Thanks
Scott N5SM

Scott:
I suggest you return or sell the KAF2.  You can install EITHER the KAF2
OR the KDSP2, but not both.  They both go in the same spot.  I don't
have the KDSP2, so I can't compare the two, but I believe most people
agree it is superior to the KAF2, although the KAF2 works pretty well if
you are operating mainly CW.

Scott,

Unless you do quite a bit of physical modification to the K2, you cannot
use both of them - they both fit into the same physical space.

The KDSP2 has filtering with more selections than the KAF2, and adds
noise reduction, and other neat functions unavailable for an analog
filter such as the KAF2.

I prefer the KAF2 for CW because it is somehow easier on my ears than
the KDSP2 - hard to explain, that is a very subjective assessment.  But
for SSB, the KDSP2 wins hands down - the KAF2 only provides a low-pass
filter for SSB while the KDSP2 has several quite usable functions as
well as filtering in SSB.

The KAF2 and KDSP2 cannot both be installed in a K2.  They use the  
same connector and provide some of the same functions (clock and  
audio filtering).  However, the KDSP2 has beat cancellation and noise  
reduction plus there are more filter settings, which can be varied  
via the menu.

Scott,
Even if you choose to install the DSP, the current draw of the KAF2 is
lower, so you may want to keep it to swap in for those situations if you
do much portable operating.  The KDSP2 can be turned off, but it starts
up back on again when you turn your K2 off and on.
