Happy World Amateur Radio Day
An anonymous reader writes "There are over 700,000 ham radio licensees in the USA and about 2 ½ million worldwide. Today, this international community of wireless communications devotees are celebrating World Amateur Radio Day, recalling the advances Amateur Radio Service has made for modern man. Their theme for 2012 is Amateur Radio Satellites: Celebrating 50 Years in Space in remembrance of the launch of the first Amateur Radio satellites OSCAR 1 on December 12, 1961 and the launch of OSCAR 2 on June 2, 1962. Their ranks have included people like Steve Wozniak of Apple and Jack Kilby who invented the integrated circuit, Dr. Karl William Edmark who invented the heart defibrillator, Scott Durchslag, the Chief Operating Officer at Skype, and Dr. John Grunsfeld of NASA and the Hubble Space Telescope. This is the 87th anniversary of the foundation." -
Broadcast Radio Turns 100
GraWil writes "On Christmas eve 1906, a Canadian physicist named Reginald Fessenden presented the world's first wireless radio broadcast from his transmitter at Brant Rock, MA. The transmission included Christmas music and was heard by radio operators on board US Navy and United Fruit Company ships equipped with Fessenden's wireless receivers at various distances over the South and North Atlantic, and in the West Indies. Fessenden was a key rival of Marconi in the early 1900s who, using morse-code, succeeded in passing signals across the Atlantic in 1901. Fessenden's work was the first real departure from Marconi's damped-wave-coherer system for telegraphy and represent the first pioneering steps toward radio communications and radio broadcasting. He later became embroiled in a long-running legal dispute over the control of his radio-related patents, which were eventually acquired by RCA."
