Correct Rick!

The topic is NB... NOT... NR.

Hard to believe or understand... yet my Century-22 actually handles noise 
better than the Omni VII, and were going way back.
Could the variable 8-pole bandpass filter been designed so well that it 
accounted for such noise as well? or possibly just my experiences.

The Eagle here also does a better job than the Omni VII.

Interesting the NB in My Kenwood TS-590 works unbelievably well, yet the 
design on that one allows a variable user interface to set accordingly.

Also Good Info there N6KB
