It is called Instantrack and costs $70 for members and somewhat more for non-members. MA is the satellite orbit phase in units from 0 to 256 which corresponds to 0 to 360 deg. One orbit is MA 256 or 360 deg. (180 deg. = MA 128 and so on.) The program also tells you the mode (if you keep the schedule updated.) Looking forward to a QSO with you on AO-10 or AO-13. de K5MBV ------------------------------ Date: Sat, 20 Aug 94 06:33:47 GMT From: paperboy.ids.net!usenet@uunet.uu.net Subject: satellite communications To: ham-space@ucsd.edu Instead of picking up the 300 page book, you should have gotten the excellent AMSAT publication on how to use amateur radio satellites. AO-13 is primarily a random QSOs bird, and an excellent choice for trans-continental communications. You will need a dual band (2 meter 70 cm.) all mode (e.g. SSB) tranceiver with a directional antenna system.
