The secret history of Silicon Valley & the defense industry

The Secret History of Silicon Valley

This is a very long GoogleTechTalks video.  But, if you are interested in “black projects” related to  radio, electronics, radar, electronic counter-measures, signal intelligence, and electronic intelligence in the context of World War II, the Korean War, and the Cold War and lots of information about Stanford’s participation in classified military projects – this may be worth the watch.

If you are in to it, this is a fascinating history of military/university collaboration on black projects and the symbiotic relationship among University Engineering schools, the defense industry, and how all this gave rise to entrepreneurship in Silicon Valley and the founding of well-known companies.

Get a cup of coffee, and take a watch…  (don’t foget to check out the list of references in the Resource section below)

Morse Code is not dead; Back in style by Russian Spies in 2010

with 4 comments

For Amateur Radio license requirements the FCC dropped the Morse Code requirement years ago.  There is no current military use of Morse code.

Just when you thought that Morse Code was dead.  The Russian spies, recently arrested in the US, are keeping the The Code  alive.

10 Russian Spies Arrested in the US (6/29/2010)

According to CBS news

According to court papers in the case, the U.S. government intercepted a message from Russian intelligence headquarters in Moscow to two of the defendants. The message states that their main mission is “to search and develop ties in policymaking circles in US” and send intelligence reports.

The complaint alleges that some of those charged had a long-term goal to become “sufficiently Americanized” in order to gather intelligence in the U.S. and to “recruit sources who are in, or are able to infiltrate, United States policy-making circles.”

The complaint says that the “agents” were trained in “foreign languages; agent-to-agent communications, including the use of brush-passes; short-wave radio operation and invisible writing; the use of codes and ciphers, including the use of encrypted Morse code messages; the creation and use of a cover profession; counter-surveillance measures” and more.

Good, the code is back in style

The R-353 is a Russian spy radio set developed and used at the height of the Cold War, in the early 1960s. It features an advanced built-in burst encoder for sending coded messages in morse code at very high speed, in order to minimise the risk of detection by enemy interceptors and eavesdroppers. Radios like the R-353 are very rare and only very few have survived.

German World War II Military Radios w/ Demonstrations & The History of Nazi Television Broadcasting

leave a comment »

The Torn.E.b was a workhorse of the German armed forces under Adolf Hitler. It was a very basic, 4-tube regenerative receiver. This example is completely unaltered from the time it was made 66 years ago. 7 out of 8 of the frequency ranges were perfectly tuned, while the other range was just slightly out of tune. I just had to replace one vacuum tube in the receiver to get it working.
