Hi

Just this week had an experience that confirms your findings.
Had a bad street lamp outside creating 30db over S9 noise across all bands.
The K2 was basically useless, with either combination of NB1 or NB2, Hi 
or Lo threshold. Couldn't copy anything but noise.
Turned on my Kenwood TS940s and with either NB1 or NB2...no noise at 
all, could easily copy signals that were too far under the noise for the K2.
The K2 NB  works great on the noise created when my xyl runs the 
blender, then again so does the 940s.
