[Elecraft] K3s Line Out (stereo)

[Dave Sublette]

My K3s arrived over the weekend and I have been setting it up. I am using
the rear Audio jacks to drive either headphones, or the Line out to drive
an amplifier and two speakers in the stereo mode.

The headphone jack has stereo output ok.  But the line out only has right
channel audio.  Left channel has nothing but a low hum.

I am testing them one at a time, using the same cable. So it is not a case
of a bad cable.  The plug inserts to the same depth in both the headphone
and line out jacks, so I believe the plug is properly inserted,

I have been through both the Main Menu and Config menus, item by item.  I
see nothing that would give the option to turn off the left channel of the
line out.

Anyone have any suggestions?

Thanks,

Dave, K4TO
