  • From the 1918/1919 Annual Report of the Chief Signal Officer to the Secretary of War: SCR-55: This type number was formerly assigned to a vacuum tube detector used with the SCR-54 receiving set. Later the type number for this detector was changed to DT-3 and later to DT-3A. It was thought that a vacuum tube detector would eliminate some of the difficulties of the SCR-54 set and give increased sensitivity and when used in combination with a two-stage amplifier would perform all of the functions of the French 3-ter amplifier. The set was first designed in the summer of 1917, being then designated as the AR-5. Samples were taken to the American Expeditionary Forces in the fall of 1917 by Co. Culver. Favorable reports were received from American Expeditionary Forces in January 1918 but it was concluded that the crystal detector was sufficiently sensitive. The set was later modified by Western Electric Co. and complete Signal Corps drawings were made by the radio laboratories.
