[App_rpt-users] Beagle Bone DTMF issues

[Ken]

I normally turn off radio-relax on all my systems because certain users key
up a lot of false dtmf's and I find that annoying.  The price you pay for
that is, when you do want dtmf to work, you have to have a clean signal into
the repeater and hold each tone something like a half a second to get
decodes.  Your speed-dialer is not going to work without radio relax
enabled. Not sure if this has anything to do with BBB, since the program is
the same on both (I think!)

   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!
