[MRCA] Armstrong Days at InfoAge

[Al Klase]

Hello MRCA,

I almost forgot to invite you folks to the Armstrong Celebration at 
InfoAge on 10-11 November.  The Radio Technology Museum has a couple of 
WWII electronics exhibits, including one dedicated to tactical 
communications.

Radio Fans,

2012 marks the 100th anniversary of the development of the regenerative 
radio circuit by Edwin Howard Armstrong an electrical engineering 
student at Colombia University. This invention not only greatly improved 
the performance of radio receivers, but would also become the basis for 
modern radio transmitters, making voice transmission, and radio as we 
know it, a reality.

The New Jersey Antique Radio Club’s Radio Technology Museum will host an 
observance of the occasion at the InfoAge Science History Learning 
Center and Museum in Wall Township, NJ on November 10th and 11th from 1 
to 5 PM. There will be a display and demonstration of a wide range of 
vintage regenerative radio receivers with a formal presentation at 2 PM. 
The other InfoAge museums will be open as well. Admission is free. A 
five-dollar donation to InfoAge is suggested.

Working receivers on display will include a mock-up of Armstrong’s 
original circuit receiving a simulated spark radio-telegraph 
transmission, a WWI era naval receiver, early regenerative broadcast 
receivers, more sophisticated “regens” that dominated amateur radio and 
the early phases of the short-wave-broadcast craze in the 1920’s and 
30’s, and a naval RAL receiver that served throughout WWII.

Armstrong is arguably the greatest radio inventor since Marconi. His 
regenerative receiver was followed in 1918 by the superheterodyne, the 
basis for nearly all modern radio receivers. During the 1930’s Armstrong 
developed high-fidelity FM broadcasting. His FM technologies also found 
their way into two-way mobile radio, and radar during WWII.

See: http://www.rtm.ar88.net/Armstrong_Days_at_InfoAge.html for pictures 
and up-to-date information.

Contact me if you have a favorite radio you'd like to add to the display 
or a presentation you'd like to make.

Best regards,
Al
