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

[Jon Perelstein]

The area I live in has gotten much noisier (QRN) over the past few years
and it's killing me.  I know that there are stations I want out there -- I
can kinda sorta hear them but I can't hear them over the noise well enough
to have a QSO.  As much as possible I've checked everything in the house
and the local telephone poles and one of my neighbors was even kind enough
to replace the circulator motor in his Koi pond, but the noise level is
still pretty bad.  I mostly operate digital modes on 80-10 (PSK, RTTY,
Olivia, etc.) with a fair amount of CW and the occasion sideband QSO.

My K2 does not have the KDSP2 (or the KAF2) and the noise level drives me
nuts.  My FT-897 does have DSP, and the problem isn't as bad as on the K2,
but the effectiveness of the 897's DSP seems limited, especially on digital
modes.

Is it worth building a KDSP2 or not?  Those of you who have one what do you
think of it.  I've listened to the sample on the KDSP2 page (
http://www.elecraft.com/KDSP2/kdsp2.htm) and it sounds impressive, but what
are people finding in real life?    Recommendations?  Thumbs up or thumbs
down?

Thanks and 73s
