[Elecraft] KNB2 - looking for experience with mods that made it effective

[Don Wilhelm]

Stan,

As I indicated, slow rise time noises (like powerline noise) will not be 
squelched by the KNB2 nor the KNB1.  They will work on fast rise time 
noise pulses like from auto ignition noise or lightning, but will not 
work on continuous noise sources like powerline noise.

The KX3 (and the K3) handle the NB function differently, and in many 
instances can be effective for powerline or household appliance noise.  
For the K2, the only cure may be with the KDSP2 Noise Reduction algorithms.
