Title: How can we send interplanetry communications?
Post by: syhprum on 10/10/2008 11:17:45: I understand transmissions have taken place from the Ukrainian space centre beamed at the planet Gleise 21.5 ly away and possibly inhabitable.
I have sent an email to this institute asking for technical details and if I receive a reply will pass them on.

But why haven't THEY sent us a message? Perhaps they have a budding Schotky, even now, developing a transistor. . . . . .

Quote
William Bradford Shockley (February 13, 1910 – August 12, 1989) was a British-born American physicist and inventor.

Along with John Bardeen and Walter Houser Brattain, Shockley co-invented the transistor, for which all three were awarded the 1956 Nobel Prize in Physics. Shockley's attempts to commercialize a new transistor design in the 1950s and 1960s led to California's "Silicon Valley" becoming a hotbed of electronics innovation. In his later life, Shockley was a professor at Stanford, and he also became a staunch advocate of eugenics.

Walter Hermann Schottky (23 July 1886, Zürich, Switzerland – 4 March 1976, Pretzfeld, West Germany) was a German physicist who invented the screen-grid vacuum tube in 1915 and the tetrode in 1919 while working at Siemens. In 1938, Schottky formulated a theory predicting the Schottky effect, now used in Schottky diodes.

Post by: lyner on 13/10/2008 08:32:30: The Klystron is certainly the 'power tube of choice' as it's so efficient when working narrow band. Such an elegant bit of electron beam engineering.
