[Elecraft] K3 line out only provides left channel audio

[Victor Rosenthal 4X6GP]

For some reason, I am not getting any right channel output from the LIN 
OUT jack of my K3, either in diversity or normal mode.
I hear both receivers properly from the headphone jack, but when I 
connect my phones to the line output, I can only hear the left channel, 
which is the main RX.

Line out is configured for NOR, level is 10. L-R MIX is set to A B, 
though it shouldn't matter in diversity mode. It isn't a cabling issue, 
because I have the problem with the phones directly plugged into the LIN 
OUT jack.

I never tried to use this feature before, so I don't know if it worked 
before.

I hope there is something I'm overlooking here...
