ARC-5 - Academic Dictionaries and Encyclopedias

The AN/ARC-5 Command Radio Setis a series of <rradio receivers, transmitters, and accessories used to provide two-way <rMorse code and AM <rradiotelephone communication for U.S. Navy aircraft during <rWorld War II and the years following. It was an improvement of the Navy's ARA/ATA command set. Similar units designated SCR-274-N were used in U.S. Army aircraft. The Army set is based on the Navy ARA/ATA, not the later AN/ARC-5.

History

The AN/ARC-5 command set was used by the <rUS Navy from the latter part of World War II into the post-war era. It was fitted in many different aircraft types for communication between aircraft, navigation, and communication back to base. Units were available that covered much of the <rMF, <rHF, and <rVHF spectrum. Despite the use of octal base <rvacuum tubes, they were compact, rugged and light weight. Many became surplus after the war and were often converted for <ramateur radio use. [[http://www.shlrc.mq.edu.au/~robinson/museum/command.html Command receivers ] ] The term "ARC-5" has come to be a generic, though incorrect, term for all similar command set units, including those designed by the Aircraft Radio Corporation in the late 1930s. [[http://aafradio.org/flightdeck/arc5-1.htm Entire ARC-5 ] ]

The ancestor of the AN/ARC-5 system was the U.S. Navy's ARA/ATA system, with initial deployment in 1940. The designations ARA and ATA are a pre-WWII Navy equipment nomenclature. The major units of the ARA are five receivers covering 0.19 to 9.1 MHz, each unit with its own dynamotor power supply. The major units of the ATA are five transmitters covering 2.1 to 9.1 MHz, using a common transmitter dynamotor/screen modulator unit. Most units were made by the Aircraft Radio Corporation (USN manufacturer's code CBY). Many units were also made by Stromberg-Carlson (USN manufacturer's code CCT).

To equip <rUS Army Air Corps planes, the US Army adopted in 1941 a reduced set of these radios known as the SCR-274-N that was electrically almost identical to their ARA/ATA equivalents, except for receiver output and modulator sidetone audio transformer output impedance. It was mechanically almost identical except for most later units being left unpainted aluminum in contrast to the black crackle finish of the Navy sets. The designation SCR-274-N is a pre-WWII Army equipment nomenclature. The Army did not acquire a receiver covering 1.5 to 3.0 MHz, nor a transmitter covering 2.1 to 3.0 MHz. Initially, the Army did not acquire a 3.0 to 4.0 MHz transmitter, nor a 0.52 to 1.5 MHz receiver, but need to communicate on the common civil airfield frequency of 3.105 MHz plus the anticipated USAAF use of the AN/ARR-1 homing adapter (see below) compelled adding these units to the SCR-274-N. Early Army units were made by Aircraft Radio Corporation, but the vast majority was made by Western Electric, plus a few by Colonial Radio and others.

The main units of both the Navy and the Army systems were usually installed in three-receiver racks and two-transmitter racks. Units not in service could be stored on board the aircraft, just as one would store tuning units of other types of radio equipment.

In late 1943, the U.S. Navy fielded an improved and more flexible set of radios known under the new Joint Army-Navy (JAN) nomenclature of AN/ARC-5. A receiver and transmitter were added that provide four-channel crystal-controlled VHF-AM operation, along with a rarely encountered set of transmitters that provide coverage of 0.5 to 2.1 MHz.

The following is a table of ARA/ATA, SCR-274-N, and AN/ARC-5 major components that would comprise a typical three-receiver, two-transmitter installation. In addition, several miscellaneous components are listed. A blank in the component ID column indicates t[...]
