Tony, I have AGC SLP set somewhere around 12 like you. That isn't the
problem. Distortion is the inevitable effect of DSP noise reduction.
The higher the S/N ratio, the less NR is needed, so I end up turning
NR on and off manually according to S/N conditions (on SSB).
Someone else was asking for NR comparisons with other radios. I had a
chance to compare K3 to a SGC-2020 ADSP2 (the late, advanced edition,
highly regarded) -- NR is about equally effective, as is overall weak
signal performance on SSB. However, the K3 has much more pleasant
audio, with or without NR.
I also have a ClearSpeach DSP speaker (purchased in '99), which
reduces any noise that is steady-state, like background hiss. It's
good, but K3 NR is substantially more effective.
I still believe that there is room to improve the NR effect on steady
background hiss.
Nobody has commented on my description of my NR seeming to get worse
over a few weeks (while using the same firmware). I've begun to doubt
my own sensibilities.

Hi Windy,
I wonder if adjusting the AGC SLP would have an impact on NR
processing? I
have AGC SLP at 12 and when I need NT it is set for F1-2. Maybe a
higher AGC
SLP would cause less distortion with stronger signals?
73,
N2TK, Tony
