- AMSAT-OSCAR_7 abstract "AO-7 (aka AMSAT-OSCAR 7) is the second AMSAT-NA constructed and Phase 2 amateur radio satellite launched into Low Earth Orbit on 15 November 1974. It remained operational until a battery failure in 1981. On 21 June 2002 the satellite was heard again on its 2 meter beacon (145.9775 MHz CW) after 21 years of silence, and 27 years in space.AMSAT reported AO-7 still semi-operational on 6 April 2006, with reliable power only from its solar panels; the report stated the cause of the outage was a short circuit in a battery and the restoration of service was due to its becoming an open circuit. The satellite eclipses on every orbit during the northern summer and autumn; the rest of the year it is in continuous sunlight and alternates between transmission modes A and B.".
