McArthur, KC5ACR, will be the keynote speaker at the 2006\n>AMSAT Space Symposium to be held at the Crowne Plaza Hotel in Foster\n>City, California, October 6-8, 2006. Commander McArthur is well\n>known to ham radio operators - during his six months aboard the ISS\n>he became the most active radio amateur ever to serve in space.\n>Commander McArthur logged more than 1800 QSOs, and earned the ARRL\n>Worked All States Award. His impressive track record also included a\n>record 37 school contacts, Worked All Continents (including\n>Antartica) and 130 DXCC entities.\n>\n>Astronaut McArthur is a veteran of four space flights that include:\n> * STS-58 - October 1993 (Spacelab Life Sciences Mission 2)\n> * STS-74 - November 1995 (Shuttle-Mir Docking Missing 2)\n> * STS-92 - October 2000 (ISS Assembly Mission 3A)\n> * Expedition 12 - October 2005\n>In addition Bill has made four spacewalks (two each aboard STS-92 and\n>Expedition 12) and was on backup crews of Expeditions 8, 9 and\n>10. He will be featured during the Annual Banquet on Saturday\n>evening, October 7, 2006.\n>\n>The 2006 Space Symposium will be a joint meeting with the ARISS\n>International Delegates and will also include the IARU Satellite\n>Advisory Panel annual meeting, and a meeting of AMSAT International\n>Delegates.
