USALS is good. It gets me almost to where I want, but it never hits the mark right on.
My Fortec 786 is also very touchy when it comes to moving the dish. Even a slight push of the manual move buttons sends it a little too far. A movement counter would allow me to pinpoint the position. If you have any
satellite receivers with one of these counters, you realize how useful they are.
Also, a graphical display of all the satellites positions in the belt is a great help. On my Satcuiser, I see a little ball moving on an arc past all the satellites as the dish moves.
There's always a hundred reasons for not adding a great feature that costs nothing in hardware and only a few lines of software code.
