Was this the first time you were going to that particular satellite?

I read in the directions that this positioner has a feature called "Autofocus". And that it will go back and forth before storing the position of the satellite.

Seems to me USUALS is a "computer program" which calculates the position of all the other satellites based on the position of one known satellite. But where the satellite is and where the best signal may be received for that satellite may be slightly different.

So I think what this would do is "know" where a satellite is located, but test to be sure it is finding the best signal for that satellite? Or perhaps there is conflicting information with stored satellites and for some reason it can't rely on the USUALS software?

If this were true, then this would happen the FIRST time you went to each satellite, then the SECOND time you went to that same satellite, the positioner would go directly there????

Is this what is happening?

I don't know how "smart" these things are, but I know the capability is there to talk back and forth between the receiver and positioner. What about the situation where someone entered the wrong location for where the dish was located. Say they were in Florida and told the receiver/positioner they were located in Iowa. In theory the receiver/positioner could know it was not finding satellites where they should be, then set out to find the satellite on its own - searching the entire arc.

Just throwing out wild guesses here.... I know sometimes when they design things like this, they try to design them to work in many different situations. Like what if someone enters the wrong location? What should the positioner do? Or what if the location entered is slightly off from the actual location? What should the positioner do?
