[Elecraft] K3: NB says "IF N/A"

[Ron D'Eau Claire]

Hello Frank:

Try CONFIG:KNB3. You'll probably see "not inSt" saying it's not enabled.
Rotate VFO B to say "rF nor", then exit the menu and turn the K3's power off
then on again to enable it.

Hi,

While participating today in the HA DX contest, I tried to reduce a 
kind of ignition noise. I switched on the noise blanker and noticed 
that I could only adjust the DSP NB; the second line said "IF N/A". I 
am sure this worked some time ago, but as I don't regularly use the 
noise blanker, I can't say at which moment it stopped working...

Has anyone experienced this before? Did I screw up some config 
setting, or is this a hardware issue?

Thanks in advance, 73
