Setting Up Fsync 1200 Decode For Soundcard Input or RTL-SDR

Fsync 1200 Decode demodulates both /\/\otorola MDC1200 and Kenwood FleetSync. You can choose either sound card input or input from RTL-SDR.

First we need to make sure all the dependencies are met. Open a terminal and type:

$ sudo apt-get install rtl-sdr sox libpulse-dev



Hopefully everything needed was installed without errors. Next, download Fsync 1200 Decode. Open a terminal and type:

$ git clone https://github.com/russinnes/fsync-mdc1200-decode.git



Then navigate to the Fsync 1200 Decode directory:

$ cd fsync-mdc-decode



Now we build the software so it's configured for your system. Type:

$ ./build.sh



Now, if you have any problems like I did, open "build.sh" in a text editor and copy the script and execute it via command line. Should be something like this:

$ gcc -o demod demod.c fsync_decode.c mdc_decode.c $(pkg-config --cflags --libs libpulse-simple)



Now our executable has been created to run the program. To start the program using soundcard input type:

$ ./demod 1



To start the program using rtl-sdr input type:

$ ./demod 2



Hopefully, you have everything up and running. As always questions and comments are welcome. Happy hunting, folks!
