This program generates an APRS-IS passcode for a given amateur radio callsign. It's implemented in C and based on the algorithm described in the APRS-IS source code.
To build the program, run the following command in the terminal:
make
Run the program with the callsign as an argument:
./aprsispass <callsign>
Note: Only supply the base callsign; do not supply an SSID or prefix.
