[Elecraft] K3 - Splitting main/sub audio to 2 headphones

[Don Wilhelm]

Stew,

You should have no problems with paralleling 2 headphones on the audio 
output of the K3, with no need for any external mixer.  If there is a 
significant difference in the response (SPL) of the two headphones, that 
may present a volume problem, in which case, some secondary 
amplification may be required for one or the other set of headphones.  
Since the gaming headset has a volume control, that alone may be 
sufficient - try it and see what the result may be.

I've strung together 2 stereo sockets with one fed from the right and the other from the left side of the front panel phone output and this seems to works well. With the channels linked I get Main in both ears in one headphone set and Sub in both ears in the other, and when the sub rx is off there is Main in both.

A quick search however hasn't found a mixer that separates the input channels.....
