Hi Doug, KE4MSG
Since OSCAR-6 and all LEO satellites I have used north center rotors with
limit swiches operating on south and I got problems pointing exactly the
antennas during the ascending orbits when the satellite comes from south.
If you use south center rotors than the limit switches will operate on north
and you will get the same problem for descending orbits when the LEO
satellites comes from north.
For HEO satellite like OSCAR-10, OSCAR-13 and AO40 I have used another
antenna system with south center rotor and limit switches operating on north
because for most of the time the above HEO satellites were available with
azimuth changing from west to south to east or vice versa but never passing
