In general the Noise Blanker acts only on repetitive pulse noise.  It does 
little to nothing on random noise.  And if you are working a strong station, 
the NB should be off.  Otherwise the peaks trigger the Blanker.  
Narrow bandwidth filters have group delay that activates the Blanker as 
repetitive pulsed.  A wider filter allows the Blanker to be more effective.
