The "Village Radio Program" was sponsored by the CIA during the Vietnam conflict, through a front organization known as the Office of Public Safety (this series of radios are also known as "OPS radios"). The purpose was to provide simple radios to the local civilians, so that they could inform officials of Viet Cong activities. The radios were built under contract with Radio Industries (a subsidiary of Hallicrafters, purchased in 1963), and included the HT-1, the HT-2, the TR-5 "Hamlet Radio", the TR-20 "Village Radio", and probably the TR-35A, among others. HT-1 units that have come into surplus channels recently are unmarked - earlier units have ID plates. Radios in the OPS series were used in other places in addition to Southeast Asia.
