[arm-allstar] USBradio

[David McGough]

Hi John,

All the software is already installed in the RPi2-3 hamvoip release; you
can run the chan_usbradio driver with no changes needed.

So, in your rpt.conf file, for the node you're wanting to use usbradio 
with, simply use a statement like:

rxchannel=Radio/usb

...where "usb" is the node stanza in the usbradio.conf file.

I run usbradio on several repeaters where I still have PC computer based
controllers. My experience is that the software performance on a RPi3 is
still well below the performance I see on the PC, mainly amounting to 
audio clicks, etc....But, it will work and certainly works better on the 
RPi3 than the RPi2.

I'll also comment that more software enhancements are coming in the next 
beta release, providing additional enhancement over the V1.02. More 
details about this soon.
