The Dependable 'Angry-9': Workhorse of the Special Forces

摘要

The AN/GRC-9 ('Angry-9', Figs. 1 and 2) was a low-power transmitter/receiver (TX/RX) portable field or vehicle set widely used by the USA. Its design originated with the Avco Mfg. Corporation (USA) at the end of WW2. Later versions were built under licence in Europe by TRT (Paris), Telefunken (Germany) and others. The radio was used by forces during the Korean and Vietnam wars, and well into the 1960s. It was also deployed by NATO. Germany and France built copies with various improvements, such as especially external power amplifiers. It saw considerable service in Africa, Indonesia, and across many other areas around the world.
