Wes,
I have been saving an old U100 rotor for possible elevation control, and never thought to use anything other than the stock controller. Your idea really makes a lot of sense. Glad I read this thread before going the clackety clack route.

Nothing wrong with using the U100 controller as-is. I used a pair of them
for a year or so working the earlier Oscars and had no problems tracking the moving satellites with the U100. K8AC "Tarmo Tammaru" wrote in message ...
