Dear Dr. Mills,

I must be a little dense, because I can't imagine how you get the audio
into the ADC without going through the mixer.  Could you expand a little
on this for the benefit of the chimelorn?  FWIW, I've hacked upon the
code a little myself, and a great deal of what needed work was precisely
getting the mixers to fly right (FreeBSD w/ multiple radios environment).
