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

[Mike]

Richard,

The problem is, as usual, my lack of understanding of how something works. Now that I 
realize that MMTTY can select either channel, I get it. Unfortunately my PSK software 
can't do that. :-(

Thanks to both you and Joe for the guidance.

73, Mike NF4L
