Hallicrafters SCR-299 Mobile Radio in World War II
Videos for Engineers

Hallicrafters SCR-299 Mobile Radio in World War II - RF Cafe Video for EngineersThe definition of "mobile," at least as it pertains to battlefield communications, has changed significantly since this Hallicrafters SCR-299 radio was developed during World War II. The SCR-299 is an adaptation for battlefield use of what began life as a transmitter for amateur radio operators. Ruggedization of the entire unit was performed by factory engineers to ensure it would survive the rigors of rapid deployment over hill, over dale, as the soldiers hit the dusty trail. RF Cafe visitor Paul A. recently sent me a link to this video documentary produced by Hallicrafters showing the SCR-299 being used in the field as well as some cool factory factory production footage. Often when I am looking at an old house, or car, radio, or airplane, I envision the people who were alive at the time, putting the lath and plaster on the walls of a home, or wrapping a paper-dielectric capacitor lead around a post used in point-to-point wiring of a radio, or maybe installing the seats in a vintage car - nameless, faceless souls who helped build the world we enjoy today. A lot of old film footage is now available on the Internet to help restore some of the anonymity.

About a year ago I published a page of WWII-era advertisements in the ARRL's QST magazine.

Flashback:
On December 8, 1941, the day after the Japanese attack on Pearl Harbor, the FCC issued a "Notice to All Amateur Licensees" that began thusly: "All amateur licensees are hereby notified that the Commission has ordered the immediate suspension of all amateur radio operation in the continental United States, its territories, and possessions." - compliments of FDR, the guy who gave us internment camps for Japanese Americans ($1.6B in reparations was paid to their families in 1988).

Here is a short article I wrote the suspension of Ham radio.
