Armstrong Days Rescheduled at InfoAge / 2013-01-26 & 27

 

The Armstrong Days observance has been rescheduled to 26 - 27 January 2013 due to the Hurricane Sandy aftermath.

This will align this hopefully annual event with Armstrong's demonstration of his regenerative receiver to  Chief Inspector David Sarnoff, at the American Marconi High-Power Station at Belmar, NJ on 30 - 31  January 1914.

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 January 26th and 27th, 2013 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.
