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 through north. 73" de i8CVS Domenico ----- Original Message ----- From: "DOUGLAS WILLETS" <douglaswill...@verizon.net> To: <amsat-bb@amsat.org> Sent: Sunday, November 06, 2011 3:28 PM Subject: [amsat-bb] Rotor > I am setting up a satellite station and have the following question.
