This contains the APCO P25 decoder block for GNU Radio and is derived
from the GNU Radio how-to-write-a-block example. This is only part of
the software - you should visit the project website is at
http://www.sedition.org.au/op25 for more information.
This package requires that gnuradio-core is already installed. It also
depends on some GNU Radio prerequisites, such as boost and a suitable
GNU Radio extension to demodulate C4FM. We suggest you use the 4FSK
demodulator from
http://radiorausch.googlepages.com/GnuradioFourLevelFSK.html.
To build the OP25 decoder you need to use the following commands.
$ ./bootstrap
$ ./configure
$ make
$ make check
Once you've done this you'll need to install
$ sudo make install
