From: Richard B. Gopstein <GOPSTEIN@RUTGERS.ARPA> I am interested in listening to satelites. I have been able to hear Oscar 9, 10, and 11. I am a bit confused though: What modulation technique is used on these Oscar satelites? I assumed that they would be the same as the RS satelites (sideband), but the little information I was able to find suggested that they transmit NBFM (narrow band FM?). Is this just on the beacons, or also the transponders? Where can I find out this info in the future? If they really do use FM, is it possible to receive them (Oscar 9 at least) on a hand held assuming I had a good circularly polarized antenna? Thanks in advance, Rich -------

Rich, Get a copy of the Satellite Experimenters Handbook ffrom the ARRL. It will tell you everything you need to know about getting the equipment and so on for satellite work. By the way, the mode is sideband and cw as you thought. Chuck... W5USJ
