Soviet Military Radio R - 108m With AmplifierUM - 2

R-108m soviet infantry VHF radio.Good conditions , with headsets  , with  new antenna "KULIKOVA".Most Common Russian Radios Found Around the World•Developed in the 1960s•Used in Large Quantities in Warsaw Pack Countries primarily by Infantry for Company to Battalion Communication•Replaced the R-105d/108d/109d Family of Transceivers with Similar Technical Specifications•Frequency Range:–R-105m: 36 -46.1MHz–R-108m: 28 -38.5MHz (artillery units)–R-109m: 21.5 -28.5M...Hz (anti-aircraft artillery)•Transmitter Output Power: Approx. 1 Watt •Modulation: F3(FM)Simplex •Can Be Operated Remotely and Used as Radio Relay Operation•Sensitivity: 2 μV for 20 dB Quieting•Power Source: Two sets of 2NKN24 2.4 NiCad batteries•Replaced by R-107 Series•Antennas:–Short "Kulikov" Antenna (constructed of a series of aluminum beads strung on a steel cable, a stiff spring on the end keeps pressure against these beads and a semi rigid but flexible antenna results. Releasing this spring tension collapses the antenna allowing it to be rolled up for easy storage.Size and Weight–Radio: 0.31 x 0.17 x 0.325 m; Power portable VHF radios type r-105D, r-108D and r-109D is about 1 Watt. When working on the whip or beam antenna range may reach respectively 8 and 25 km. To increase the range of these radios are applying additional power amplifiers type UM 2.MIND power amplifier-2 is an independent design in packaging manpacks self-powered. It allows to increase the transmitter power portable VHF radios not less than 7-10 W. Because the range of VHF radio in sight is directly proportional to the size of the quartic root power transmitter, power amplifier SSPA-2 gives the possibility to increase the range at about 1.5 times The radio and amplifier UM-2 is both working.The signal go to antenna KULIKOVA on the amplifier and after throught cable to  the radio.Working both radio and amplifier.I use 4 batteries 1, 2V and 9v to amplifier UM-2.Original manual R-108m and copy of manual UM-2.Weight with packing is 22 kg.
