R-123 "Magnolia" (Р-123 «Магнолия») is a Soviet military HF/VHF radio transceiver designed for use in tanks and other armoured vehicles. The device was made in the Ryazan radio plant.
The R-123 set was commonly used in conjunction with the R-124 intercom system in armoured vehicles. Introduced in the early 1960s, the R-123 set was also adopted by other Warsaw Pact members and exported to countries such as Finland, Egypt, and Iraq.
