KNB3 Option?

[Julius Fazekas n2wn]

Joe,

It's not an option, it's standard!! Actually there are
two, DSP and a board.

There had been a bit of a delay from the parts vendor
that has slowed the board version delivery down. I'm
not sure of the current status/

Several of the beta testers have reported excellent
results with only the DSP version. The pair should be
outstanding.

I just got my hardware one a couple of days ago.  The real problem
with having the DSP one work so well, is that it will take a lot
of time comparing the two to figure out which is better.  

Reminds me of the old saying - if you have two watches, you are
never sure what time it is.

Both of the noise blankers have 21 different settings - so it will
take me awhile to figure out the best ones.  Maybe we need a new
mail reflector strictly for comparing NB settings.

I guess the real question on the HW NB would be ......
aside from the fact that it gets rid of a whole lot of noise,
is there the crud from adjacent signals introduced when the
HW NB is turned on ..... like on some "other" radios?

Well - there might be.  The HW noise blanker does not have the
roofing filter in front of it.  I don't fully understand how
the bandwidth is determined - and haven't had a chance to test
it with loud signals and an appropriate noise situation yet.

The cool thing about the DSP filter working so well is that
it is after the roofing filter - and will not be affected by
nearby signals.
