[Elecraft] K3 No Sub Audio In Right Speaker

[Bud Governale, W3LL]

How can I have the sub receiver audio play from the right speaker along with the main receiver playing in the left 
speaker?
I have no sub receiver audio from the right speaker. I do have audio from the main receiver in the left speaker.
Using headphones, I have main in left ear and sub in right ear. I'd like to hear the same thru left and right speakers.
What have I set incorrectly?
