I have a big antenna with a rotor that I would like to replace the mechanical control box with an electronic control. The system is 4 wire. Does anyone know what the signals are to the rotor? Is there any kind of standard for such devices, or would my brand (sears, >15 years old) be a special case? Eventually, I would like to add a timer so that when using a VCR to do unattended recording, the antenna could be automatically rotated to the best location at some programmed time. Thanks, kevin@berkeley.edu

Your rotator probably consists of a pair of "selsyn" motors. You can read all about them in AC machinery texts from the fifties and sixties. They might still have a few in the basement of Corey Hall.
