For a schematic of all parts on these radios please visit this link. Most pieces on this example are original USGI WWII vintage, some parts like the clasps are updated post WWII issue. The serial number on the radio data plate is 1957 and is contract marked 29310-PHILA-44-01 which indicates it was made in Philadelphia in January 1944. The tubes are intact and present. Knobs and jack covers present. Markings are in English meaning this is not a post war French version. Canvas pieces are late "transitional" OD.

These radios are the quintessential WWII radio communications gear. As seen on all battlefields - and used by the Army and the Marine Corps - the "walkie talkie" is everyplace a ground pounder had to go. The SCR-300/BC-1000 was a portable radio transceiver used by US Signal Corps in World War II. This backpack-mounted unit was the first radio to be nicknamed a "walkie talkie

In 1940, Motorola (then the Galvin Manufacturing Company) received a contract from the War Department to develop a portable, battery powered voice radio receiver/transmitter for field use by infantry units. The project engineering team consisted of Daniel E. Noble, who conceived of the design using frequency modulation, Henryk Magnuski who was the principal RF engineer, Marion Bond, Lloyd Morris, and Bill Vogel. The SCR-300 operated in the 40.0 to 48.0 MHz frequency range, and was channelized. It, along with mobile FM tank and artillery radios such as the SCR-508 (20.0 to 27.9 MHz) and the SCR-608 (27.0 to 38.9 MHz) marked the beginning of the transition from low-HF AM/CW to low-VHF FM for combat-net radio.

Although a relatively large backpack-carried radio rather than a handheld model, the SCR-300 was described in War Department Technical Manual TM-11-242 as "primarily intended as a walkie-talkie for foot combat troops", and so the term "walkie-talkie" first came into use.

The final acceptance tests took place at Fort Knox, Kentucky in Spring 1942. The performance of the SCR-300 during those tests demonstrated its capacity to communicate through interference and the rugged quality of the design. Motorola was to produce nearly 50,000 of the SCR-300 units during the course of World War II.

The SCR-300 saw action in the Pacific Theater, beginning in New Georgia in August 1943. Colonel Ankenbrandt informed General Meade that "they are exactly what is needed for front line communications in this theater". In his point of view, the main difficulty was keeping them supplied with fresh batteries.

The SCR-300 saw heavy use in the Normandy invasion and the Italian campaign. It also became "key equipment" that helped deter confusion in the Battle of the Bulge.

Signal Corps Radio set SCR-300-A
The SCR-300 was an 18-tube battery operated radio transceiver. It used an FM transmitter section and a double superheterodyne receiver. It incorporated a squelch circuit, an automatic frequency control circuit, and a crystal controlled calibration circuit.

We cannot test this unit and cannot guarantee functionality but from visual inspection its appears to be complete and undamaged.
