MacDoppler is a straightforward Ham Radio Satellite Tracking application for your Mac that allows you to visually track multiple satellites and help you to manually operate your rotators.

Amateur radio, also known as ham radio, uses the designated radio frequency spectra with the purpose of private recreation, non-commercial exchange of messages, self-training, wireless experimentation and emergency communication.

MacDoppler promises to offer the desired level of station automation, from antenna pointing and Doppler tuning up to fully automated Satellite Gateway operation. To take advantage of all MacDoppler’s capabilities, you should use a full duplex satellite radio.

What is more, MacDoppler offers support for a wide variety of rotor controllers such as SatEL, PrimeSat, Endeavour AutoTracker and more. A list with all supported rotor controllers is available on MacDoppler’s webpage.

MacDoppler is designed to automatically find and download the keplerian elements and sort the track list in real time according to the next pass. On top of that, you can use MacDoppler to predict dead spot crossing and avoid interruptions generated by the beam heading passing a dead spot.

Moreover, MacDoppler provides speech advisory for the next satellite AOS and maximum elevation. You can also take advantage of the Horizon window and view the upcoming passes on the timeline.

MacDoppler comes with built-in support for Satellite Gateway using Ontrack ADR101. You can use the Tuning Dial Tracking to fine tune the downlink from your radio’s front panel while MacDoppler automatically adjusts the uplink.

From MacDoppler’s main window you can easily add satellites to your track list, switch between the 2D and 3D view, check the downlink and uplink along with the horizon.
