Andy,
The K3 DSP works just fine. In fact all the filtering, modulation,
demodulation as well as many other radio functions are implemented in
DSP firmware, not just the NR that has been recently discussed.
These folks have specifically been talking about the K3 Noise Reduction
algorithms. There are many settings for the K3 NR algorithm, and they
are set on a per mode basis. It may take a bit of experimenting to find
the setting that is most effective for your use since the best one
depends on the characteristics of the noise as well as the mode being
used. Some have commented that since they had the external device and
it worked well with other radios, they also found it useful with the K3,
and they did not have to experiment with the variety of settings offered
by the K3.
If you are happy with the noise reduction in the KDSP2, be aware that
all the K3 DSP firmware has been designed by the same person who
designed the KDSP2 - Lyle Johnson KK7P.

I was planning on getting a K3. Can someone explain to me why so many ops use
external DSPs. Is the K3 DSP not working well enough. I would prefer to have
everything in a box without many peripherals, as I got these anyway for SO2R,
antenna switching etc....
So, again, how good or bad is the K3 DSP. My main focus is CW and low bands.
Well I am on the high bands too, but I do not see a need for DSP there.
Current rig is a K2.
