[QUOTE="harm lok, post: 1089555, member: 415123"] Position in any way is not a problem. I will store the count / angle in F-ram. But we have to think about a the calibration when the disk is moved by wind. A kind off automatic re-synchronization. My idea is to store the limits counts / angles and based on the last position turn to the nearby limit position to re-calibrate. Another idea is to combine the positioner with a signal strenght measurement. But i have a little knowledge about hf-designs. We need a kind of conversion from signal strenght to a 0-5V voltage to input to the processors ad converter. It would be nice to have a automatic sat-focus option. Maybe some member has the diagram of this circuit in the lt8700. It is always good to have a wish list for hobby projects . . [/QUOTE]
