[Elecraft] Have AF control both the Main & SUB volume

[Gary Smith]

I'm trying to set up the K3s to have both 
the sub and main controlled by the AF knob 
and not finding what I had done before.

Looking at the manual under CONFIG:SQ MAIN 
it says:

SUB RF gain normally sets the sub 
receiver´s RF GAIN level. If this knob is 
assigned to main/sub squelch (CONFIG:SQ 
MAIN), then RF gain for main/sub is 
controlled by the main RF gain control.

When I go to CONFIG:SQ MAIN and select via 
VFO A it offers numbers ranging from 1-29 
and then it says =Sub Pot With two options 
of SQ MAIN and SQL N/A which defaults back 
to SQ MAIN.

None of the above locks the volume of the 
Sub to the Main like I had it set on the 
K3, AF still controls the main and SUB 
controls the SUB volume.

I am missing the obvious. 

Suggestions?

Thanks & 73,

Gary
