[aprssig] Project-25 for amateur radio

[John Habbinga]

Bob, there is a low-speed data mode transmitted along with digitized
voice on Project 25.  However, it passes data at 88.9 bit/s.  As far
as I know, there are no applications that has made use of this
feature.  I doubt that it would be very practical to use "APRS over
P25," but I could be wrong.
