[Elecraft] K3 Audio routing question

Tue Jul 6 12:00:25 EDT 2010

There is a balance control on your rig, you have to assign the SUB AF Gain in the Config menu to "balance" mode, but without the AB BA Mixer on too, you would only have audio in the left or the right.  With the mixing ON, AND balance control you can have mono audio in diversity mode with both speakers active.  

Obviously others are seeing my point now.  It can be a VERY useful tool, even for diversity mode.
