[Elecraft] VFO B receive not heard in headphones with SUB on

[Mike K2MK]

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.

73,
Mike K2MK
