DESCRIPTION:The mostly Australian designed and constructed satellite AMSAT 
 OSCAR 7\, or AO-7\, was launched on 15 November\n1974 and has just reached
  50 years in space. It is the oldest man-made satellite in history to have
  ever worked for as\nlong as that - and it is still working! The primary a
 im of AO7 is to provide earth-satellite-earth radio communications\nbetwee
 n Radio Amateurs within its “foot-print” on the earth below . Using on
 e or more satellites\, Amateur radio\ncommunications can be achieved over 
 very large distances.\n\nRick will describe how an Australian University t
 eam was formed in 1967 with the aim to plan\, design\, and construct an ea
 rth orbiting satellite that was to become known as AO-5 when it was launch
 ed on 23 January 1970. Soon aŌer that\, work commenced on AO-6 and AO-7. 
 Rick will describe the construction of the AO-6 and AO7 satellites. They w
 ere the first satellites to use of CMOS logic for their Radio Teletype an
 d Morse coding and decoding functions. Rick was involved in the design of 
 that logic. Other firsts for the AO satellite series were their unique an
 tennas and magnetic spin stabilisation.\n\nSo\, of all the satellites ever
  launched throughout the Space Age it is AO-7 that is still operating toda
 y after 50 years in space providing Radio Amateur operators throughout the
  world with radio communications even including the Polish Resistance duri
 ng their struggle for independence. And in its long life\, AO-7 has defie
 d all those who said CMOS would never survive in space.\n\nSpeaker(s): \,
