This project implements a real Open Source implementation of the AX.25 protocol stack for the Ham Radio community.

The program provides an AXUDP, a KISS and a TCP Interface. It can route all AX.25 traffic from one interface to another. The main purpose is HAMNET / Packet Radio interoperation.

Both AX.25 V 2.0 and V2.2 protocol is implemented. The program can be configured with a XML file and is based on a very flexible plugin design. You can start the program in a small GUI or as a server process with the same configuration file.

The chosen platform is CLI (.NET) to allow interoperation among all major operating systems (Windows, Linux and the Mac).

Cooperators and testers will be greatly appreciated. Contact me at for more information.
