Macdoppler

* 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.
