[arm-allstar] usbradio

[Doug Crompton]

Tom,

 For many reasons it is not recommended to use usbradio on the Pi. usbradio
is a somewhat flawed driver even on the PC. It causes audio distortion and
in general audio that is not up to par for Allstar and certainly not as
good as simpleusb. It would be better and easier to find a COS line - a
line that goes either high or low with RX signal from your equipment if
that is possible.

If you must use usbradio you are somewhat on your own and don't expect
great results. To enable it all you need to do is place a valid
usbradio.conf file in /etc/asterisk and change the rxchannel= command in
rpt.conf. It would however be much better to try using COS and simpleusb if
you can.

One of the issues with usbradio even often on the PC is the outgoing audio
has periodic distortion. Since you don't hear your outgoing audio you often
do not know that but others do. I can pick out a usbradio node with
listening very quickly. On our list for 2018 is a new channel driver that
should solve this issue and allow both the benefits of simpleusb and
usbradio plus some other nifty features.
