My up/down link sat antennas are mounted on a common boom,\nfixed el., above my HF yagi. I turn all of it with a very old Ham IV rotor\nand the original CDE controller. Here is the problem. The rotor turns fine,\nbut there is no readout of direction. This first began to occur\nintermittently, then finally the needle just stopped moving while turning\nthe antennas. I have checked the wiring at both ends and all seems in\norder. I am really hoping to avoid having to tear down the rotor, so any\nsuggestions on trouble shooting from \"outside the case\" would be greatly\nappreciated.\n> Thanks much.\n>\n> Craig\n> N6RSX\n>\n>\n>\n> NOTICE: This communication may contain privileged or other confidential\ninformation.
