APRS References

Good news!

This site is slowly getting archived in favor of our new wider-community effort at Traquito.

Head over to our new site at Traquito to check out the $14 WSPR tracker, realtime maps/graphs, and other great resources!

Many thanks to the many people who have come before me and done great work to document and implement the bits of APRS that I was able to study.
