I use a Timewave DSP-599ZX in conjunction with my K2. As good as the K2 is
on its own the Timewave puts it in whole new league (for the better).

I like how it is in essence three distinctly seperate DSP units (Voice, CW &
DATA), each with their own unique features for each mode. And you can
operate two seperate rigs off one 599ZX (discrete A & B channels), so it's
almost like having 6 DSP units in one box. And oh yea, it has an integral
FSK signal detector/generator & 'rigblaster' interface.

Hit the 'random' button and the QRM basically goes away (like a
clearspeech?). Hit the 'tone' button and that annoying heterodyne is
automagically gone. And the audio doesn't sound like it's coming out of a
'tin-can' that is usually associated with outboard audio filters

There is no way I could cover all the features of the 599ZX. Just go to the
Timewave website for details.

I know I sound like a Timewave ad but I actually like it so much I have two,
one for my K2 and one for my Icom 751A.
