MacDoppler v3.8.1

* MacDoppler will read in the Keplerian elements (in either format),
calculate the position and relative velocity of the Satellite you are
tracking and automatically adjust the Doppler shift on both transmit and
receive as well as pointing your antennas.
* Without registering, the application will run for 30 minutes and track
the satellite(s) you choose and display the proper Doppler corrected
frequencies that can be entered manually in any rig. When registered with
AMSAT ($50.00 US) MacDoppler will connect to your radio and rotor
controller through any two serial ports and make the corrections for you
once a second.
* A Track List Dialog allows you to track up to 8 satellites
automatically.
* MacDoppler features full predictive dead spot crossing so that a pass
is never interrupted by the beam heading passing a southern dead spot.
* A slider control allows you to sweep the VFO through the transponder
range while the transmit frequency tracks the receive frequency. When you
hear something interesting, MacDoppler continues to track the frequency
through the Doppler changes.

Requirements

MacDoppler requires an Apple Macintosh II or faster (some features only
supported on Power PC), 2.0 to 4.0 MB of RAM (over and above the OS),
System 7.6.1 or later (MacOS 8 required for the Frequency Slider to
work). The Application is FAT Binary, an FPU version is also available
for 68k Machines with a Floating Point Unit.
