Ww2 Military Radios - The SCR-300 was a portable radio transceiver used by the US Signal Corps during World War II. This cavalry backpack unit was the first so-called "walkie talkie" radio.
In 1940, Motorola (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 team consisted of Daniel E. Noble, who conceived the idea of using frequency modulation, Hryk Magnuski, who was the chief 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. Along with other mobile tank and FM gun radios such as the SCR-508 (20.0 to 27.9 MHz) and the SCR-608 (27.0 to 38.9 MHz), the SCR-300 marked the beginning of the transition of network radio from below . -HF AM/CW to VHF low FM.

Although a portable radio rather than a handheld model, the SCR-300 is described in War Departmt Technical Manual TM-11-242 as "primarily intded as an infantry combat walk-talkie", hence the term " walkie-talkie" came first. in use.

Final acceptance testing took place at Fort Knox, Kentucky in the spring of 1942. The SCR-300's performance in those tests demonstrated its ability to communicate through interference and the rugged design quality. Motorola would produce nearly 50,000 units of the SCR-300 during World War II.
The SCR-300 saw action in the Pacific Theater beginning at New Georgia in August 1943. Colonel Ankbrandt informed Geral Meade "they are exactly what is needed for front line communications in this theater". From his own opinion he used the greatest difficulty to fight fresh bats.
The SCR 300 saw heavy use in the Normandy invasion and the Italian campaign. It was also the "key equipmt" that helped prevent confusion during the Battle of the Bulge.
The SCR-300 design began private use in 1947 as "Wireless Set No. 31".

The SCR-300 is an 18-tube VHF battery operated half-duplex radio transceiver. It uses an FM transmitter section and a double superheterodyne receiver. It incorporated adjustable circuit expansion, wide frequency possession circuitry, crystal controlled calibration circuitry, easy-to-use channel selection, lock switch for pre-accidental frequency change, and radio or retransmission capability using two SCR-300 units. cable assemblies.1 / 5 Show caption + Hide caption - Soldiers standing in front of an SCR-270, the first radar equipment used in WWII.

June marks the 160th anniversary of the founding of the Signal Corps, while XXXX is the 75th year since the end of World War II. Therefore, this article will focus on the achievements and contributions of the Signal Corps in World War II.
The scope of duties handled by the Signal Corps during World War II was significantly increased from its work during World War I. More than ever, success in battle depended on good communication. Commanders using field radios were able to maintain constant contact with their troops during the rapid advance. At its peak strength in the fall of 1944, the Signal Corps consisted of more than 350,000 officers and men, more than six times as many as had served in World War I.
The signal corps took responsibility for one of the most important systems used in World War II - radar. Raised from the Seal Corps Laboratories at Fort Monmouth, the radar was first successfully demonstrated in 1937. The radar set up at Pearl Harbor in December 1941 detected incoming Japanese bombers, but unfortunately, the warnings were not ignored Radar is considered to have revolutionized WWII, affecting the outcome of two major conflicts: the Battle of Britain and the Battle of the Atlantic. The Japanese were at a distinct disadvantage in the Pacific theater with no radar, while Allied ships were equipped with radar warning.

Insignia Corps Laboratories was responsible for designing and building most of the communications equipment used by American forces during World War II. Laboratories SCR-510 in 1941. He explained. This is the first backpack FM radio. This early pioneer of frequency modulation circuitry gave the company a reliable and static-free communications front. Multichannel FM radios (such as the AN/TRC-1) were first used in the European Theater of Operations in 1943. FM radios and radars, both products of the labs at Fort Monmouth, were commonly listed in the systems. He made a difference in World War II.
Other, more specialized fields are also considered under the Signal Corps. Photography had long been a part of the Signal Corps mission, but its value and usability reached new heights, especially in the second half of the war, in part because of improvements in training and organization. Photographic Division of the Great Pictorial Office on June 17, 1942. Photographic training was first held at Fort Monmouth, but was transferred to the former Paramount Studios in Astoria, Long Island, in the new Photographic Signal Corps. One hundred The Signal Corps created orientation and training films, using notable talents such as Frank Capra, who was commissioned as a major in the Signal Corps in 1942, and Theodor Seuss Geisel, who played a member of Capra's film crew. The Signal Corps also created an extraordinary pictorial record of World War II.
Other notable WWII missions included the homing pigeon program - pigeons were particularly useful in places like the Pacific jungle where stringing wire was difficult. Many heroic pigeons served bravely in battles, often receiving wounds, but still delivering messages. In addition to transmitting messages, the Signal Corps retained responsibility for signal security and operational intelligence. 2. Service standards The Company has completed intelligence collection services. Activated at Fort Monmouth in 1939, the unit expanded to headquarters size in April 1942. In the field, personnel operated observation posts in the US and around the world. During the war, the battalion grew to a maximum of 5,000, including members of the Women's Corps. In fact, the Signal Corps was the first force service agency to request female Corps personnel and employed one of the first percent of female communications substitutes within the technical services.
Throughout the war, the Signal Corps served in a variety of mission support roles and many of the most important missions were the work of the dedicated civilians and soldiers at Fort Monmouth.Original Item: Unique Available.

All pieces are original USGI issue of WWII vintage. Rail cases are original WWII style, not post war spring loaded shells. The serial number on the radio data plate is 6577 and is marked PHILA 44.
Tubes are intact and present. The present covers the knot and the jack. Noted in English means this is not the post war French version. The canvas pieces are a nice mix of khaki and mostly "transitional" OD. Excellent original crinkle OD paint.
These radios were the primary radio communication equipment of WWII. As seen in all battles - and used by the Army and Marine Corps - the "walkie talkie" is the ground breaking point.
The SCR-300/BC-1000 portable radio transceiver was used by the US Signal Corps during World War II. This cavalry backpack unit was the first so-called "walkie talkie" radio.
