[Elecraft] [K3} NB and Sub-rx

[t.izak]

Gang,

I'm trying to get the NB to function when I press the "SUB" button (sub-rx
installed) on the K3 as I have a horrific power line noise here. The K3 NB
does a great job on reducing the RFI but when I press the "SUB" button, I
can hear the RFI noise in the headset but MAIN is ok.

I tried using "BSET" but that doesn't do anything...am I missing something
here?
