[arm-allstar] arm-allstar Digest, Vol 4, Issue 1

Mon Sep 1 13:16:35 EST 2014

Hello Doug,

Problem solved, it's amazing what a night's sleep can do !!

In rpt.conf I had a mis-match with duplex=1 and duplex=0.

I've now changed them all to duplex=0 and audio is now OK as I forgot 
that Duplex in rpt.conf tells apt_rpt how to handle the audio passed 
through the R/T interface..

Now waiting patiently for my other BBB's to arrive..

Regards,

Ian..
