My Orion came with 1.371.  I've tried 1.369 and 1.372.  To my ears,  
1.372 is "noisier" and the NR circuit doesn't seem to work as well.  
There is the inconsistent switching using the NR button.  Using HRD,  
it can be consistently switched on and off and adjusted.  But even  
then, it just doesn't seem to knock down the noise as well as 1.371.

Have been trying something else this week which seems to help.  On a  
noisier band I get clicking, popping, thumping--however you might  
want to describe it--between characters when sending with the QSK  
delay less than 10%.  (I'm only sending at 20 wpm.)  I tried my  
Timewave 59+ that I use with my TS 850s but that changes the sound of  
the note and are just more knobs to tweak.  Last week I picked up a  
nearly new SCAF-1 and that does seem to make a difference to my  
ears.  It knocks down quite a bit of the thumping and I keep the QSK  
delay at 0-3% now.  Since the center frequency is 450hz, it would  
work even better for someone listening for a lower note--I'm at 650hz.
