Linux based portable APRS Digipeater

This project is an APRS (Amateur Position Reporting System) digipeater. A digipeater receives positions and re-transmits them. This digipeater will also have other functions such as QDOS querying capabilities. This project involves hardware and software and will make a complete digipeater that is portable. The digipeater will run off of either an internal 12V Gel-cell battery or an external car battery. Just add an antenna and it is on the air.
