Here’s an interesting piece of radio history.

Promotional Film From The Sixties – Fairchild Briefing on Integrated Circuits

Filed Under (Radio/Comm. History, Uncategorized, YouTube Goodness!) by Jonathan on 17-02-2011

As promotional videos go, this is rather interesting. Very detailed and an interesting look at the burgeoning technology of the sixties. Below is a quote from the video description on YouTube:

[Recorded: October, 1967]
This half hour color promotional/educational film on the integrated circuit was produced and sponsored by Fairchild Semiconductor Corporation and first shown on television on October 11, 1967. In the film, Dr. Harry Sello and Dr. Jim Angell describe the integrated circuit (IC), discuss its design and development process, and offer examples of late 1960s uses of IC technology.
Fairchild Semiconductor Corporation was one of the most influential early high-tech companies. Founded in Palo Alto California in 1957 by eight scientists and engineers from Shockley Semiconductor Laboratory, Fairchild Semiconductor Corporation was funded by Fairchild Camera and Instrument Corporation of Syossett, New York. Rapidly establishing itself as a technology innovator based on its invention of the planar manufacturing process in 1959, the company developed the first monolithic integrated circuit, the first CMOS device, and numerous other technical and business innovations. French oil field services company Schlumberger Limited purchased Fairchild in 1979 and sold a much weakened business to National Semiconductor in 1987. In 1997 National divested a group, formed as the present Fairchild Semiconductor, in a leveraged buy-out. The company re-emerged as a public entity based in South Portland, Maine in 1999 under the corporate name Fairchild Semiconductor International, Inc.

Fairchild Semiconductor presented its new products and technologies with an entrepreneurial style, and its early manufacturing and marketing techniques helped give Californias Santa Clara County a new name: Silicon Valley. It was one of the early forerunners of what would become a worldwide high-tech industry, as evidenced in this short promotional film.

Pretty neat stuff, brought to you by The Computer History Museum.

History of Communications – Electronics in the US Navy

Filed Under (Radio/Comm. History) by Jonathan on 03-10-2010

I’ve posted a lot of articles here about the history of radio – most of them weren’t even from the US.  Here is the complete web listing for “History of Communications – Electronics in the US Navy”.  Originally prepared in 1963, it covers a large base of history from the civil war and good focus between the two world wars.

Though this is a military publication, you will find some of the roots of radio and electronics with Faraday, Hertz, etc.  This publication is rather readable, even if you aren’t a ham or a “tech junkie”.  I have an interest in military history and gave segments for a friend to read, he had no issues with the technical content and found it interesting (as he served in the Navy as well).

It is a rather long read, but I didn’t find a pdf of it anywhere.  If you know of a PDF version of this book, please comment below.  I’d much rather read this out and about than sitting in front of the computer.

Signal Corps Training film for the SCR-694

Filed Under (Go-Boxes, Radio/Comm. History, YouTube Goodness!) by Jonathan on 11-08-2010

Sorry for the delay….. the hazy days of summer yield to a LOT of amateur radio and public service events!!!!

Today, we take a trip back in history to the American Signal Corps.  Here is a series I recently stumbled upon with training for the SCR-694.  Interesting radio (kinda like one of the early “go-boxes”.  I am amazed when I see these or similar at hamfests and people just pass them by – they’re interesting.  Maybe I love the history behind our beloved hobby to much…… so I couldn’t resist.

Bletchley Park archives will soon go online

As I’ve stated in the past, I’m fascinated by the use of radio communications by governments for espionage and wartime use.  When I came across this little nugget, I couldn’t resist.  What a joy it will be for those of us that can’t quite make it over to visit Bletchley Park.

The BBC has an article at:


Bletchley Park (really hard to resist using “BP” for this one…..) has been trying to do this for quite some time.  Dwindling funds, repairs needed for the site have just made this one of those “round to it” projects. Many documents are too fragile to handle at this time and will take awhile to get posted online, but it will indeed make for a fascinating online resource.

I’ve had the pleasure of actually getting my hands on  real, wartime Enigma machine and it was REALLY NEAT!!!  You can read about it, but there is nothing like actually using one to get you even more interested in this topic.  Professor Tom Perera gives a number of great discussions at the New England ARRL Division convention in Boxboro Mass (I spoke to Tom at Dayton and he said there may not be a presentation this year).  His site is a HUGE wealth of information on this topic (and CW keys).  If you ever get the chance to hear him give a presentation – JUMP ON IT!!!!

His website is:
