[Elecraft] K2 options KDSP2 & KAF2

[Don Wilhelm]

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.

73,
