I just successfully installed Doug's (WA3DSP) Beagle Bone Black installation on a two node repeater system using two URI's and a Belkin 4 port USB hub in an attempt to remove my power hungry old P4 rack server from All Star service. Everything seems to be running well on the BBB with only 14% CPU usage on stand by (2 nodes) and little to no audio distortion while testing. I am having a heck of a time getting either node to reliably decode DTMF especially when using Motorola transceivers. (On the old P4 server, the DTMF decoded remarkably well using any radio...) I have been looking at the old P4 config files and comparing them to the BBB config in an attempt to see what has changed... Doug has "radio relax" turned off by default (normally on by default in the acid release). Is this relevant? Thanks! -Eric (KB6BZZ)
