R-114D is a Soviet portable VHF radio station of the Astra series radio networks (it is on the same model line as the R-105D , R-108D and R-109D radio stations). Designed to equipPAN for the interaction of infantry and paratroopers with aviation [1] [2] . It has been in operation since 1957 as a replacement for VHF radio stations with amplitude modulation [2] [3] .

Description
This is a knapsack, wearable, telephone with frequency modulation, a transmitting and receiving radio station with the ability to remotely control and relay. It provides searchless and unobtrusive communication in radio networks in the tactical link of company-platoon and in car radio nodes. Also known as interaction radio station [4] . Among the features, smooth tuning and a frequency step of 50 kHz, an optical frequency scale, and FM radiation are distinguished [2] . The type of transmitter is a smooth local oscillator (LC-generator), the type of receiver is a superheterodyne with one transformation [2] .
Antenna devices - a flexible whip antenna 1.5 m high with a 3-beam counterweight, a combined antenna (flexible whip plus six knees and a 5-beam counterweight, total height 2.7 m), an on-board antenna (combined whip plus a special bracket with a shock absorber and connecting conductor 1 m long) and an increased antenna (a beam antenna 40 m long with a gradually decreasing opposite end, at a height of 5-6 m near the radio station). The combined antenna is used to work in the parking lot, the beam and high - for work from shelters and for longer ranges. There is a bayonet antenna connector for the Kulikov antenna [2] .
