The SCR-536 had an RF output power of 360 milliwatts. The range of the unit varied with terrain; from a few hundred feet (about a hundred metres), to approximately one mile (1.5 km) over land, and 3 miles (5 km) over water. [5] Under the Army Nomenclature System, the BC-611 transceiver was the core component of the SCR-536 Signal Corps Radio ...
Some even sub-specialize in military radio collecting and undertake to restore and operate surplus communications equipment, much of it dating back to World War II, from AN/ARC-5 command sets and US Signal Corps SCR-300 and SCR-536 walkie talkies to exotic gear like the British Paraset, a small espionage transceiver supplied to Resistance ...
The first handheld walkie-talkie was the AM SCR-536 transceiver from 1941, also made by Motorola, named the Handie-Talkie (HT). [9] The terms are often confused today, but the original walkie-talkie referred to the back mounted model, while the handie-talkie was the device which could be held entirely in the hand.
The term SCR was part of a nomenclature system developed for the U.S. Signal Corps, used at least as far back as World War I.Three-letter designators beginning with "SC" were used to denote complete systems, while one and two-letter designators (such as "BC", for basic component, "FT" for mounting, etc.) were used for components.
Raytheon developed the RT-196/PRC-6 following World War II as a replacement for the SCR-536 "handy-talkie". The AN/PRC-6 operates using wide-band FM on a single crystal controlled frequency in the 47 to 55.4 MHz low band VHF band. [2]
The SCR-300, designated AN/VRC-3 under the Joint Electronics Type Designation System, 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 ".
SCR-299 housed in K-51 panel van. The range of the SCR-299 exceeded original specifications, sometime establishing contact over 2,300 miles (3,700 km). [4] The SCR-299 provided reliable communications with England during the North African campaign, and in Normandy on D-Day, served as a connection between two airborne divisions with Britain. [5]
The SCR-694 is a portable high frequency two way radio set that was used by the U.S. military during World War II. The SCR-694 provides transmission and reception of AM radiotelephony and MCW or CW radiotelegraphy within the frequency range of 3.800 to 6.500 MHz .
