[Elecraft] Sub RX Noise Blanker - 3051

[Joe Planisky]

Hi Paul,

I just got stumped by this, too.  In order to turn the sub RX NB on  
and off independently of the main RX, you have to set CONFIG:VFO  
IND=Yes.  This allows the main and sub RX to be on different bands (so  
pay attention when changing bands!)  If CONFIG:VFO IND=No, the sub RX  
NB is supposed to follow the setting of the main RX.  At least that  
what I *think* the intent is.  It's mentioned in the release notes for  
FW 3.03.

However, that said, I don't think it's working right.  When I have  
CONFIG:VFO IND=No and turn on the NB, it's quite clear from the sound  
that the sub RX NB is NOT turning on.  When I have the main and sub RX  
set to share the main antenna and turn on the NB, I hear the noise  
disappear from the main RX side, but it's still there in the sub RX  
side.

Can anyone else try this and confirm whether it's working as expected  
with CONFIG:VFO IND=No?
