RBM 1 field radio

The Soviet, portable two-way (transmission-reception) field radio RBM 1 (Rus. РБМ-1) is a battery-powered superheterodyne designed for military communication. The device enables telephone (cable), telegraph, and radio communication over simplex. The radio was widely used towards the end of World War II and was later used for training young radio operators and in enterprises and the state-owned economy of the USSR. It was also one of the means of communication for armies of the Warsaw Pact. Communication range: 2 kilometres with cable; whip antenna – radio 10 km, telegraph 15 km; horizontal dipole antenna - radio 17 km, telegraph 35 km; 7 m high communication mast - radio 30 km, telegraph 50 km. The use of a whip antenna allowed communication while in motion while the other two were used as stationary equipment.
