You are right Jim... my comments weren't helpful and I apologise for
making them.
Minutes after hitting the send the regret began.
I had installed the KNB2 a few years ago and it's just that I have not
found
it to work even with impulse noise. I had heard the demo sound file before
I installed the KNB2 and I have been frustrated that mine doesn't work as
per
the demo sound file indicates. I have also had conversations with others
who
have had similar results.
I actually have been tempted to purchase a second kit and install it just
in case
there is a fault with mine, but I have since moved and now I don't have
much
need for a noise blanker, so this idea was shelved a year ago.
The NB in my K2 won't even have any impact on noise that my PROII noise
blanker
and my FT-101Z noise blanker kills dead. However, in saying that I still
sold my
PROII because my K2 is a much better radio to listen to and the KNB2
doesn't
detract from it being a first class bit of kit. In fact, after several
years of
owning it this year it became my main station radio.
Regards,
Dave

A blanket "It doesn't. Don't waste your time--" isn't really a good thing
to say at this time. #1, it DOES work on many types of impulse noise.
If
you are looking to eliminate atmospheric static noise (QRN) then yes, it
doesn't work. Pulse type ignition noise from vehicles passing your
location, or running near you, it does an excellent job of removing.
Also,
much of the power line noise caused by leaky/cracked insulators and bad
grounds on your nearby power lines are usually effectively removed by the
KNB2. This is what the KNB2 was designed to do, and it is actually
better
at this job than the NB in my IC-706MKIIG and other rigs I have had in
the
past.
Again, if you are trying to eliminate QRN, there isn't anything
available in
ANY rig that I know of that will do that.
Another thing to consider -- any time the noise blanker is ON, it will
cause
distortion in the received audio of the station you are listening to if
there is a reasonably strong signal within 5 to 10 KHz of the signal you
are
trying to receive. This occurs with ANY noise blanker, not just the
KNB2.
