The NR  function is supposed to determine the signal level in the noise and
then  adjust the DSP filter to accentuate the signal through this noise.
Once the  determination is made by the NR logic, then adjusting the level
from 1 to 9  has no further effect on the currently "captured" or determined
signal and  the NR setting.  The 1 to 9 setting only determines the time it
takes  for the NR logic to make its sampling of the signal and resolve it  or
conclude what it is and adjust


That is the description in the Orion I manual and it is the way the NR  
worked up through 1.371.  After 1.371, the NR started to work like in other  radios 
- ineffective and the higher you turned the number, the more the NR  kicked 
in until you got distortion.  Unfortunately, you get distortion  before you 
hear any noise reduction.
 
I realize I only have an Orion I to play with but I think this part is  
common to both radios.
