Rotor version 1.3 released
Tom Lindner (DL2RUM) has released version 1.3 of Rotor, a full-featured antenna rotor control app for macOS.
Rotor can control up to 9 rotors. It is able to track stations and satellites automatically with both azimuth and elevation and currently supports SPID, Yaesu (GS-232A/B), DCU-1 and EasyComm rotor protocols. In connection with the Ham Radio Logger RumLogNG or WSJT-X Rotor can control your antenna direction fully automatically.
Rotor predicts satellites passes for the next seven days for your location and calculates sked times for a given satellite to a dx location. It shows positions, footprints and ground tracks on a 2D or 3D map.
Key features:
- controls up to nine rotors (easily to extent if someone uses more)
- supports often used rotor protocols (azimuth and elevation)
- customisable azimuth indication – use your own background map or any other graphic
- supports bidirectional antennas and antennas mounted with an offset
- full automatic control from RUMlog and WSJT-X (JTDX) over network
- manual control from RUMlogNG
- user presets for azimuth ans elevation
- direct numerical or grid square entry or just a mouse click to move antenna
- Moon and satellite tracking
- satellite path predictions and illustration, sked predictions over satellite
- doppler shift correction for IC-705/9700 using RUMlogNG
What’s new in version 1.3:
- New: Added rows in the SAT table for max. elevation and doppler shift for 21 MHz.
- New: Added a second transceiver option to use different devices for up- and downlink.
- New: Added a Note field for each SAT preset. See Preferences–>Satellites–>Note. You can enter a free text note. The note will be presented when you select a SAT in the trx tracking section. It’s useful to review the band plan or other stuff to remember.
Rotor is available free of charge via the Mac App Store.
