When controlling one of the Yaesu rotors, like the G800 or G1000 with a Yaesu radio like the FT950 or FTDX3000, does the rotor need to have the Yaesu GS-232 rotor computer interface with it, or can you run the SCU-27 cable straight from the control box to the radio without needing the GS-232 interface? 73 John AF5CC
