XASTIR
Multiplatform Ham Radio APRS and Mapping Program
NOTE: Code commits were FROZEN on SourceForge in July of 2016, and the project no longer uses sourceforge. All new code is now at <http://github.com/Xastir/Xastir>.
The version you can download here has been obsolete for over 10 years, and other than by deleting the project entirely we can't disable the "Download Now" button. Don't download from here. Go to github.
Real-time tracking & messaging of stations via radio/internet APRS data streams, w/125 map formats supported....
