[Elecraft] KDSP2

[Johnny Siu]

I will not regret the discontinuation of KDSP2.  In my case, I do not feel any usefulness of the KDSP2,I sold it and replaced with a KAF2 at a much lower cost.  While there are a number of settings in KDSP2 which you can manipulate, regrettably none of the settings gave me a present result.  The artifacts from the DeNoiser is huge and much worse than K3.
IMHO, among the elecraft radios, the best Noise Reduction NR is in KX3 (I did not try the KX2).  KDSP2 is in the audio stage and did not improve any selectivity like the DSP in K3
KAF2 in the used market is really cheap.  Adding the KAF2 will not cost much but at least give you some listening comfort.  With some careful choices of R and C in KAF2 (please refer to the manual), you will find yourself a sweet spot even for SSB.

The K2 was first prototyped in October 1997. I'll bet no one back then
would have guessed that demand for parts would still be around 19 years
later in 2016.
