[asterisk-users] Radio interfaces for Asterisk - ISO image distro
I just ran across these guys - looks very interesting: http://xelatec.com/xippr/install They distribute a self-installing ISO with Asterisk, FreePBX, and some pre-built software to do "radio over IP". You'll need to buy the USB radio hardware, but it looks really interesting as a pre-built system for radio trunking using some of the Asterisk capabilities. There is a very narrow but highly interested group of people who use radio interfaces for exotic locations such as oil platforms, ships, or remote off-grid locations to connect Asterisk systems together for long-haul telecommunications access. Hopefully there will be a speaker this year at Astricon who will be going into a very complex and unique system in detail using these components; I'll announce if/when they schedule their talk.

What extra software do they have? One change is obvious: chan_usbradio is not build by default. The output from cppcheck for it: [channels/xpmr/xpmr.c:160]: (style) Redundant condition.
