[Elecraft] K3 Keying and NR No Effect Here

[Don Ehrlich]

I just keyed my K3 with and without NR (all settings) while looking at the 
keying waveform.  I used both the internal keyer and an external computer 
interface for keying and could not see any effect on the 5 mS rise and fall 
times related to NR settings or with NR on or off.
