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.
