The Hallicrafters Company manufactured, marketed, and sold radio equipment, and to a lesser extent televisions and phonographs, beginning in 1932. The company was founded by William J. Halligan and based in Chicago, Illinois, United States.
The SCR-284 was a World War II era combination transmitter and receiver used in vehicles or fixed ground stations.
The BC-348 is an American-made communications receiver, which was mass-produced during World War II for the U.S. Army Air Force. Under the joint Army-Navy nomenclature system, the receiver system became known as the AN/ARR-11.
The Wireless Set No. 19 was a Second World War mobile radio transceiver designed for use by armoured troops of the British Army. First introduced in 1940, the No. 19 began to replace the pre-war Wireless Set No. 11. Two modified versions were introduced, Mk. II in 1941 and Mk. III in 1942. An improved version from Canada was introduced in 1942 for use primarily with other forces. In British service, the No. 19 was replaced in the post-war era by the Larkspur radio system. Canadian-built No. 19s saw continued service for many years with a variety of users.
The SCR-536 was a hand-held radio transceiver used by the US Army Signal Corps in World War II. It is popularly referred to as a walkie talkie, although it was originally designated a "handie talkie".
The SCR-299 was a U.S. Signal Corps mobile military communications unit used during World War II.
Survival radios are carried by pilots and search and rescue teams to facilitate rescue in an emergency. They are generally designed to transmit on international distress frequencies. Maritime systems have been standardized under the Global Maritime Distress Safety System. Civil and military organisation's utilized different frequencies to communicate and no infringement on either sector would take place. For emergencies involving civilian aircraft, the radio frequency used is VHF 121.5 MHz and for military aircraft incidents, the frequency used is UHF 243 MHz.
The SCR-300 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".
The SCR-277 was a mobile, trailer mounted radio range set for radio guidance of aircraft. It was standardized by the U.S. Army in June 1941.
The BC-342 was a World War II U.S. Army Signal Corps high frequency radio receiver. It was used primarily as part of field installations such as the SCR-188A, but could be used with mobile sets such as the 2 1/2 ton mounted SCR-399. First designed at Fort Monmouth, New Jersey by the U.S. Army Signal Corps, it was built by various manufacturers including RCA. Many of the later units that are encountered today were manufactured by the Farnsworth Television and Radio Corporation of Fort Wayne, Indiana. Variants include the low frequency coverage BC-344 receiver, and the battery or dynamotor powered BC-312 receiver.
The M1917 was the United States' first mass-produced tank, entering production shortly before the end of World War I. It was a license-built near-copy of the French Renault FT, and was intended to arm the American Expeditionary Forces in France, but American manufacturers failed to produce any in time to take part in the War. Of the 4,440 ordered, about 950 were eventually completed. They remained in service throughout the 1920s but did not take part in any combat, and were phased out during the 1930s.
The AN/MRN-1 was an instrument approach localizer used by the Army Air Force during and after World War II. It was standardized on 3 July 1942. It replaced the SCR-241, and was a component of SCS-51.
The SCR-68 was a military radiotelephone used by the US Army Signal Corps as an aircraft radio in the waning months of World War I. Due to its many problems, primarily its inability to communicate with other radios, like its ground component the SCR-67 or the larger truck mounted SCR-108, over large distances, the SCR-68 quickly became obsolete. Nonetheless, the SCR-68 was one of the first steps towards developing more effective messaging between pilots and commanders, even beyond military usage.
The SCR-108 Radio Truck was a Signal Corps Radio vehicle used by the United States Army during and after World War I for short range air-to-ground communications,
The Radio tractor was a mobile Signal Corps Radio used by the U.S. Army for ground communications before and during World War I. Prior to World War I, trucks were referred to as "tractors", and there were also telegraph tractors, and telephone tractors.
The SCR-245 Radio was a mobile MF/HF Signal Corps Radio used by the U.S. Army before and during World War II, for short range ground communications, It was one of the first crystal controlled sets used by the Army.
The SCR-508 radio was a mobile Signal Corps Radio used by the U.S. Army during World War II, for short range ground communications. The SCR-508 series radio represented the Army's commitment to both FM and crystal tuning, and was used extensively by armor and mechanized units. The turret bustle of late series light and medium tanks was designed around this radio.
The SCR-54 was a tunable, portable crystal radio receiver used by the U. S. Army during World War I for fire control in conjunction with airplanes.
The SCR-602 also known as the AN/TPS-3, was a mobile, lightweight, medium-range, early-warning radar utilized by the United States and its allies during World War II. The radar was originally designed for use during the initial stages of an amphibious assault or military operation where its lightweight relative to other radar systems was a distinct advantage. Once larger radars such as the SCR-270 or AN/TPS-1 came online the SCR-602 could also be used to fill in gaps in radar coverage.
