Mike,
The KNB3 menu item was removed with MCU firmware 5.20 (see the release
notes).
The K3 will not operate without the KNB3, so there is no need for a menu
entry.
What kind of noise are you trying to eliminate? The NB only works on
impulse type noise such as may be experienced from automotive ignition
noise or electric fence noise.
If you are expecting it to remove local 'hum' from neighbors electronic
devices or atmospheric noise, it will not be effective. Use the NR
function for that type of noise.

Going through all the menus today (after upgrading to the latest firmware) I
do not see the KNB3 option in my menu system?!
Is that (maybe) why my IF noise blanker is not working? The board is either:
Gone
unhooked
damaged
Ideas?/Comments?
