I don't have links handy, but folks in the Ham radio community who own
repeaters often do this and I've heard there's several ways to go about
it. The software is probably free, and the interface can be as simple as
a Radio Shack 8:1k audio isolation transformer, hooked between audio out
and microphone in on the PC. Look up 'digital modes' in Ham radio for
lots of other circuits, and maybe ask around at a few radio clubs for
the software. Typically, sole-owner or more private repeater owners will
use it for CYA in case there's some future complaint about the repeater.
