Chatham Marconi Maritime Center
Videos for Engineers

Chatham Marconi Maritime Center - RF Cafe Video for EngineersOnly recently has the importance of the role played by of the town of Chatham (pronounced "kat'-um"), Massachusetts, in the success of World War II been recognized to the degree it deserves. Thanks to the effort of Chatham Marconi Maritime Center's Ed Fouhy, the extent of strategic radio operations performed there is made available both online and, to a much greater degree, to visitors at the physical location. The entire campus was totally renovated in  the 2009-2010 timeframe Foughy and his team produced a video that crams the story of years of intense activities and accomplishments into a seven-minute video. About a third of it can be viewed below, but if you want to see its entirety, you will need to visit the Center.

A separate video, also shown here, is an interview with Mr. Foughy by the Cape Cod Chronicle where he talks about the research and some of the surprising discoveries that went along with his project. The U.S. Navy used the site primarily to intercept and monitor German U-boat activities in the Atlantic Ocean. In the early days of WWII, U-boats wreaked havoc on both military and merchant ships crossing the northern Atlantic. They operated with near impunity because of the genius of German commanders and submarine crews. They maneuvered stealthily underwater and surfaced during the night in order to exchange mission intelligence and to receive orders. The success of the ploy was epic. Allied navies and merchants were desperate to re-open supply routes. When Ed visited the office of the U.S. Navy Historian in Washington, D.C., in search of information, he discovered that the head dude did not know anything about the role of Chatham Radio in World War II. "And for good reason," Foughy said, "This was a very, very secret installation."

Chatham Marconi Maritime Center Architectual Model - RF Cafe Video for EngineersThe Marconi station in Chatham, operational since 1914 as a commercial ship-to-shore facility, was commandeered by the Navy, Coast Guard, and Army in order to, among other things, deal with the U-boat dilemma. Shortwave radios and antennas were installed, and teams of operators, technicians, and intelligence officers were stationed there for the purpose of assisting in the breaking the U-boats' messaging code, and for using triangulation methods for locating and then attacking the demon vessels. Cryptographers at Bletchley Park in the UK eventually broke the infamous Enigma Machine's code, spelling the end to U-boat dominance. I was surprised to learn that Germany's Admiral Karl Doenitz did not know until the end of the war that a majority of his messages had been intercepted and decoded.

Hopefully the entire video will eventually be made available online rather than just this 3:42 minute sample, because it could be a long time before I get out to the Boston area. I love seeing B&W footage from the war era.

Here are some photos of the restoration work.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
