OK Fred thanks. Lots of great info. If you try zooming on the motor label it comes in pretty clear. 37.1 ratio. Oh well...at least the sensor is installed. Feedhorn ready to slide a corotor II in, reed sensor already installed, I think you're right. I have saved myself alot of trouble on this one. I would have to imagine my latest find, and the one I may install, may be setup the same. Will start the removal of that one next week. But before I do, a week has passed on the perferated dish and the lady should have talked to her son by then, so I'll keep my fingers crossed. Appreciate the info.
