A note about file formats

InstantTrack was traditionally delivered in self-extracting executable archive files. Nowadays (2019), such files are likely to be blocked by malware protection software, so we have fallen back to using plain ZIP files. You'll need a program that can unzip these files.

InstantTrack is now free to download, use, and distribute. Until February 2019, InstantTrack was distributed by AMSAT organizations world-wide as a fund-raiser. 100% of proceeds from InstantTrack went to support the amateur radio satellite program.
