From sitting at my desk with 2 K2/100's and an IC-746 .... and an
IC-706MKiiG in the truck .....
It seems that noise blankers in general .....
Work sometimes
Don't work sometimes
degrade signal quality sometimes
don't degrade signal quality sometimes
Coupled with (or without) a combination of pre-amps, attenuators, DSP
noise reduction and / or the DSP filters ...... You could even add one
of those noise reduction boxes that use a sense antenna.
You might get rid of the noise. Or .... you might not!
The KNB2 works real well for a $40 noise blanker. How many would be
willing to pay several hundred dollars for the noise blanker that I'd
bet Wayne could have designed?
But it's just like paddles, cars, wives and cold drinks ..... one
size/type/model doesn't fit all. I could say "use what works", but that
may not be politically correct in this case - so I didn't!

I'm in a noisy city environment. The KNB2 works 70% of the time.
Without it I couldn't operate.
I have found that messing with the pre-amp and attenuator sometimes
gets it to work.
Also, I can only remember a few times when high or low threshold made
a difference and only once where NB1 vs. NB2 made a difference.
The NB2 is adequate most of the time. I built my K2 to have one of
the very best receivers available, regardless of price. For low power
draw and portability, the K1 and KX1 fit the bill nicely. But, the
prime draw of the K2 is it's top performance.
It would be great if the NB2 could be brought to that standard.
