Greetings and happy new year to my fellow sat-ops. I thought I would try here before searching the entire ‘net, for some tips in trouble shooting a rotor problem. My up/down link sat antennas are mounted on a common boom, fixed el., above my HF yagi. I turn all of it with a very old Ham IV rotor and the original CDE controller. Here is the problem. The rotor turns fine, but there is no readout of direction. This first began to occur intermittently, then finally the needle just stopped moving while turning the antennas. I have checked the wiring at both ends and all seems in order. I am really hoping to avoid having to tear down the rotor, so any suggestions on trouble shooting from “outside the case” would be greatly appreciated.
