[Elecraft] KDSP2 and KNB2 together

[Eric Swartz WA6HHQ - Elecraft]

Both the KNB2 analog noise blanker and the noise reduction filter in the KDSP2 
  work very well together. The KNB2 is optimized for pulse type noise (from 
power lines, cars, electric fences etc.) and does an excellent job of blanking 
it before it can get further into the IF chain and cause ringing in the 
crystal filters. The KDSP2 noise reduction does a great job on broad band 
noise like background static and hiss, significantly reducing listening fatigue.
