Low Earth Orbit FM OSCARs

OSCAR:Low Earth Orbit FM OSCARs A number of OSCAR satellites can be categorized as frequency modulated (FM) low earth orbit (LEO) satellites. These are also commonly referred to as "FM LEO's" or the "FM Birds". Such satellites act as FM amateur radio repeaters that can be communicated through using omni-directional antennas and commonly available amateur radio equipment. Due to the relative ease of tuning FM as compared to SSB and the decreased distance of LEO satellites from earth stations communication can be achieved even with handheld transceivers and using manual doppler correction. The orbit of these satellites however causes the available time in which to communicate to be limited to only a few minutes per pass.
