Non-Satellite Radios (limited support)
Note: A full duplex satellite radio like the TS-2000, FT-847, IC-910, IC-9100 or IC-9700 is recommended to take full advantage of MacDoppler's capabilities. A full duplex radio is required to hear your own downlink.
Other rotor controllers not listed here support the popular GS-232 or DCU-1 protocols. Not all rotor computer interfaces provide a Mac calibration program and may need a PC or terminal program for initial configuration and calibration.
