AMSAT-OSCAR 7, also known simply as AO-7, is a second Phase 2 amateur radio satellite constructed by the Radio Amateur Satellite Corporation or AMSAT. It was launched on November 15, 1974 and remained operational until a battery failure in 1981. Then after 21 years of apparent silence, the satellite was heard again on June 21, 2002, and is still transmitting whenever it is on the sun-lit side of the Earth today. It is the oldest amateur communications satellite still in active use (as of 2022)
