[amsat-bb] please help

DEAR Amsat members.

Could you please help me.

1. How can I calibrate my yaesu rotator in azimuth and elevation?

2. I found the true north with gps and compass but don’t know what do after that?

3. I park my rotator in zero elevation (parallel to roof surface) and also zero in controller indoor. But now it's rotate down instead of up. I mean it rotates clockwise instead of counter clockwise.

4. Another problem is that when the controller show 45 degree in real it rotate 90 degree in elevation.

Any help would be gratefully appreciated.

Thanks. Nayer M
