[Elecraft] [K3] Line out, speakers, and L-mix-R settings...

Re: point #2.

I don't have a sub rx, so it's never been a problem for me, but I'm thinking of 
adding one.  How does that work if there's a RTTY  signal on both VFO's (simplex)? 
Would you have to tap A>B?

The manual sez "Use CONFIG: LIN OUT to set the level, or to switch from a fixed-level 
setting to =PHONES." Does that give you a level control using the AF knob?
