I just received a 90 cm dish replacement for the previous smaller one which was shipped in error originally.
Here is what I will do--of course, wife and kids permitting
1- Redo all calculations for a fixed dish
2- Remove the motor
3- Recheck the position of the mast to see if it's still plumb as it was before
4- Install the 90cm dish and position it to hit my true south
5- Try to get the Telstar 6 as my standard for positioning, even though I am more interested in the Telstar 5 because it has about 20 Arabic channels.
6- If this works, then I will reinstall the motor and reposition again relying on the settings I saved in the receiver from the previous install.
