Johnny, depending upon the design of the NR and its implementation, you can
expect any signal to be altered in its sound with the NR engaged. That is
the price you pay for a reduced noise level. The tradeoff is to be able to
hear and understand the signal with NR whereas you cannot without it. What
the signal sounds like is relatively unimportant as long as you can
understand what is being sent. BTW, NR with relatively narrow filters is
less effective than with wider filters.

Hi Group,
I eventually installed this option to my K2. I use it in SSB mode and
discovered the following:
1. With engagement of denoiser, the voice sounded artifical even I set the
denoise level at 1.
2. The audio output level is lowered when denoiser is engaged.
3. From some sudden large signal, the audio output is distorted. It seems
the AGC of the DSP is not working well.
Could any of you give me some advice on the above.
