I share with Steve's observation. KDSP2 is good in CW mode but not so good
in SSB when compared with IC756pro3. I eventually sold the KDSP2.
Artifacts in SSB is the thing I don't like for KDSP2.

Subject: Re: [Elecraft] K2 - DSP - Impressive
I do not argue that my settings my settings could likely use some tweaking.
My epiphany was concerning how the DSP cycled through the different
settings. The other thing that helped me was cranking the gain up. With
the gain set to higher settings, the higher beta is more tolerable. I
actually end up pulling back on the AF settings at times. But based on
your statement, I went over there and played a little bit, and ended up
with beta / decay settings in the 50 range, and depending on conditions, I
could see it going lower. But I find if I cycle through the .nr1-4
settings, and the SF1-4, I often find a comfortable setting before I end up
fiddling with the beta / decay.

David,
Wow, the default Beta and Decay settings leave me with a lot of
distortion.
I can tolerate more distortion on SSB than on CW. The denoiser makes CW
sound scratchy, but till copyable. I left the Beta setting close to the
default, but really reduced the Decay setting. I put it down to 30,
though I
did have it down to 5 at one point.
I guess I am used to DSP with less distortion. My 756PROII is able to
reduce
the noise level without the degree of distortion present in the KDSP2.
The
KDSP2 does get the job done. I starting to prefer the bandpass filtering
over the denoiser, and only use the denoiser if really needed. For
example,
I use the narrowest filter setting of 50 Hz, for the CW bandpass filter.
I've found it can work better than the denoiser in most situations.
