Thanks for the title Tom!  I am honored.
But the KDSP2 is one thing I have not gotten into closely, so please direct
the KDSP2 questions to Gary (mailto:support at elecraft.com) or Lyle Johnson
(the guy designed it).

In my quick reply earlier, I failed to mention the AGC setting - even if it
is set for the manual recommendation of 3.8 volts, it may be too high and
hold the gain down.  Test by turning the AGC off and on with no signals on
the band (if band noise is present, disconnect the antenna), and make
certain the DSP de-noiser is not running.  If you hear a change in the noise
level, the AGC Threshold is set too high.  I have seen some K2s which needed
the AGC Threshold reduced to 3.65 volts, but most I have encountered do well
at somewhere between 3.7 and 3.8 volts.  Don't forget to reset CAL S Lo and
CAL S Hi after changing the AGC Threshold if you want your S-meter to
indicate over its full scale.

73,
Don W3FPR
