USAF Sat Cat: 22829 . COSPAR: 1993-061G. Apogee: 803 km (498 mi). Perigee: 790 km (490 mi). Inclination: 98.7000 deg. Period: 100.80 min. Experimental Interferometric Microsatellite built by Interferometrics Inc, of Chantilly, Virginia. The satellite was also equipped with amateur radio equipment, constructed by AMRAD, a non-profit organization of radio amateurs, to conduct digital satellite communications experiments. The Amrad-Oscar-27 payload was an 'FM Repeater', consisting of a crystal controlled FM receiver operation at 145.850 MHz and a crystal controlled FM transmitter operating at approximately 436.795 MHz. Output power of the transmitter was normally 0.5 watts. Because of the satellite's limited power budget the amateur transmitter was on for only part of the daylight portion of each orbit. As of September 1998, the satellite passed its five year design goal.
