javAX25

AX.25 Modem in Java, for AFSK and APRS usage with Hamradio and soundcards.

• First of all, this repository is a fork from sivantoledo/javAX25, based in the great job of Sivan Toledo, so all credits goes to him. Sivan also wrote a documentation that describes how the original source-code was done. I've added this doc in the repository wiki.
• This project also tries to solve this question: https://www.reddit.com/r/amateurradio/comments/3d89f1/headless_aprs_for_linux/
• The APRS message packet definition can be found here http://www.aprs.org/doc/APRS101.PDF

Compiling

• Just clone this repository and run the following maven command mvn clean install -DskipTests. I recommend -DskipTests argument because some application maybe is already using your soundcard, then the maven process will break.

Audio Example:

Python alternative

• For Python users and programmers there is a similar project for encode AFSK over AX.25 protocol: https://pypi.org/project/afsk/ and https://github.com/casebeer/afsk
