I upgraded my old BUD system with a new Fortec Star digital receiver. I presently use my old G.I. 2400 (analog receiver)/G.I. 2000 PS (positioner) to direct my antenna position. My new receiver already has the different satellites programed into its memory, with arc locations. Can this new receiver direct my current positioner properly to satellites, or do I need to replace my current positioner, and if so, with what?
