[App_rpt-users] DMK URI questions

[Johnny Keeker]

I not sure how to interpret "you all are getting to far into the weeds," 
I guess its to say done wasted your time experimenting. Personally I hold 
an opposing viewpoint, however I agree, with dont over think it, so I 
retract my previous comments and now say, 
"dont worry about audio quality use the default codec and git-r done."

you all are getting too far into the weeds...it ain't broadcast audio, though it can sound better than most repeaters on the air today. 9600  is fine; the levels you'll get are more than sufficient to work with.  don't forget to put it into data mode and lock it.  add in the rx boost, and you'll have more than you need to do whatever you want.  let asterisk dsp if you have the cpu chops do what it does. push composite back in, set your levels, and enjoy.

don't overthink it...it's just not that complex.
