VFO B receive not heard in headphones with SUB on

Jeff Hall, W6UX-2
I haven't used my K3 much since Field Day.  Today I turned it on and engaged the sub receiver by tapping SUB.  Instead of hearing VFO B in my right ear, I only hear VFO A in my left ear.

Adjusting the SUB RF control affects VFO A volume.  It's like the radio's sub receiver configuration got messed up, or maybe one of the internal coax cables maybe came loose?  Or I guess I just forgot how to use the sub receiver!

Can someone please provide me with the troubleshooting procedures?

Thanks!
Jeff, W6UX

Hi Jeff,

After pushing the SUB button you have no volume in the right ear. Lets begin.

Are the headphones fully inserted into the jack.

Is the SUB RX RF gain control fully clockwise.

Is the SUB RX tuned to the same band or perhaps a different (dead) band. Press A-B twice to transfer VFO settings to VFO-B.

CONFIG:SPKR+PH should be off.

Press BSET and observe your antenna selection, PRE/ATT conditions, NR, etc. Make changes as required.
 
Is the outer ring of your volume knob set to NOR (for volume) or set to BALANCE (for left right balance). Either will work but you need to know which it is.

Check CONFIG:L--MIX--R. For the simplest type of operation you want A-b.
