[Elecraft] Beta 2.22 and Noise Reduction problem

[Bob Tellefsen]

Just finished installing the 2.22 beta.
Took the rig back to the shack and ran through the
various controls I use the most often.
No problem with the Noise Blanker but the
Noise Reduction does not work now.
I went through every menu I could find, and 
KNB3 is ON and seems to work ok.  I couldn't
find any menu choices for the NR function though.
Whether I tap or hold the NR button, all I
get is N/A.

Have I missed something or is there a bug in
this beta?

Thanks and 73
