[Elecraft] K2: KDSP2 - Should I or Shouldn't I?

[Guy Olinger K2AV]

Any attempt to compare my experience with yours depends on the noise, which
is as variable one place to the next as snowflakes.

But my K2 has the noise blanker in it, in addition to the DSP and all my K2
wars with noise would have used the NB if it helped at the time, and I do
not have a researcher's data catalogue on it to separate it out.

Nevertheless, I found the DSP to be a great help to the K2, particularly in
the selectivity department, and I thought adding the DSP and and the A/B
mods to be transformational.

73, Guy.
