I just did the same as Don and like him found absolutely no difference to
the waveform on the scope with or without NR at all settings, internal or
external keying.

I could however get the keying to totally loose it by switching in the NR
while actually sending - most but not every time it would change to a sort
of high frequency, highly overdriven chopped AM sine wave; not something
that could be mistaken for cw keying, hard or not. Pressing buttons like NR
while actually sending is presumably not in the script and would I assume
come under the title of 'unpredictable'.

Running the latest betaware, dsp tables etc and also the 5ms keying hardware
mod.
