Are you extending enough patience when moving? I know sending commands like switching channels in mid movement has a tendency to mess with mine. In other words I wait until I am certain it has completed it's move before issueing any other commands to the receiver.

Knowing that an H tp will move the motor faster I have at times tried to switch to a H tp in mid movement which has resulted in the motor stopping where it is. I then have to as you say back track or at least choose another sat and allow it to travel there before attempting to hit the desired sat.

The one thing I always keep in mind is the cost of these systems when encountering bug type problems. You would be hard pressed to pick up a decent feedhorn with servo & lnbs for the price of a complete system offered by Sadoun.
