To use the NR function on cw, you need to open up the filters.
The narrower the filters, whether IF or audio, the more noise
pulses are stretched, and "white" noise begins to sound like
signal. Both cases reduce the effectiveness of the NR function.
I find that I get the best results with the IF filter set around 500 Hz
bandwidth, and the same for the DSP filter. This gives the NR
function a chance to work.
So you have a tradeoff between NR versus selectivity. You have to
experiment under any given conditions to see which gives you the
best results.
Good luck and 73

Subject: [Elecraft] KDSP2-settings for CW use
Hi folks,
has anybody experimented with the noise reduction of the KDSP2 for cw?
Are there any optimum settings that one should use or are the factory
settings already optimum. Up to now I´m not very much pleased with this
particular feature, while the others are very helpful. Possibly I´m just
using it wrong.
