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.

Thanks Don and Ron.
I checked the NB and it appears to be working fine.
I added the .001 and didn't notice any significant change in the pulsing
noise I'm hearing.
I wish I could show a screen shot from my P3. There are multiple large
swaths of pulsing
S9+ RF in this rural town. I do live about 3 miles from a power plant with
large electric lines
about a mile away. I've never really gone out and tried to pin down the
noises. Sounds like
a job for the KX3 on a lonely night. In between the patches of noise it's
VERY quiet.
My glass is half full!
