  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
