Is it possible to implement Noise Reduction in the DSP for Data
A mode? Or is it a really stupid idea?
The PSK software I use -- cocoaModem for the Mac -- has a noise
reduction mode which works reasonably well when it is receiving
a broad spectrum signal -- 2 KHz or more. It does not work well
Have you tried using a narrower filter in the K3 or using the K3 NR?

Note that NR is not available in DATA A mode -- K3 manual p25:
NR turns noise reduction on. It doesn’t apply to DATA or FM
modes, or with AGC turned off.
Ray identified why I would like the K3 NR to work in DATA A when
he said, NR algorithms -need- a broad chunk of spectrum. If

Bill,
I have not found 24 bit soundcards to be a requirement for data modes.
16 bit soundcards will do just fine.
Yes, NR is not available in Data modes because it distorts the signal
and would result in reduced copyability. The object is to produce as
clean a signal as possible to the
