[Elecraft] [K3] Line out, speakers, and L-mix-R settings...

[Mike]

Joe, if you mean stand alone MMTTY, I don't understand. I wouldn't want to copy copy 
both signals.
Each copy of MMTTY could use a different sound card (given 2 sound cards) but still 
no way to direct sound by channel.

I suppose the Windoze mixer could be used to set the balance. Or cut a wire in the 
audio cable.

All that strikes me as a kludge, but I certainly don't have a better solution. :-(
