Russian Manpack Tranceiver
Tornister gerate R-105/108/109 the only changes are the space in frequencies.Technical alike inside and outside.The only is the color on the box.marking the frequencies.

The P-105M transceiver was developed in the early 60's as a replacement for the P-105D family of manpack transceivers. Used by Russian and East German armies, primarily by Infantry for Company to Battalion communication. Operating in one continuous band and output power of approximately 1 Watt. Modulation FM. Powered by two sets of 2.4V rechargeable batteries.
R-105 Russian Back Pack Set
R-105 M (R-108m, R-109 M) is a portable and a mobile backpack. Operating mode is F3 (FM), simplex. It can be operated by remote control and used at relay operation
The short antenna supplied (Kulikow) with the sets is unique in design and also reminiscent of it's WW-II German ancestry. Constructed of a series of aluminium beads strung on a steel cable, a stiff spring on the end keeps pressure against these beads and a semi rigid but flexible antenna. Releasing this spring tension collapses the antenna allowing it to be rolled up for easy storage. Better than the British system on the PRC-349, US SCR-300, and anything produced in WW II, but still not as good as the U.S. "Stanley" tape configuration that's been in use since 1949 Though the R-105M series had been reported to be out of production before 1987, the following provided by one of the radio collectors group would tend to indicate that it was produced longer than officially thought. Further, it might reflect the build up of all armaments, due to the hostilities between Iraq & Iran
The R-105M is made from the same earlier aluminium alloy princip with chambers for every radio functions.The oscillator is capsuled into a unit and work as TX and RX oscillator.As the "father" R-105/108/109D the receiver have a automatic AFC controll tracking the receiver on to TX frequency if the other radio´s tx is of frequency.This shure,could be turned off and on. Tubes: 1P24B, 1SH17B, 1SH18B
Tube TX poweramplifier 1P24B
Soviet type UM-2 is a VHF RF amplifier used to amplify the RF output of the R-105M, R-108M or R-109 family of manpack VHF FM sets. It was issued in the late 1950s and used contemporary developments: valved RF amplifier (type 6P23P) and transistor HT invertor unit. The accumulators are fitted in a separate compartment at the rear of the unit. It is built up as backpack in the same housing as for example R 105M (bakelite), only deeper in dimensions.
Wiring chema UM-UM2 and UM3
Some of the small control meter could "be hanging". It is possible to take out the complet unit this way:Take radio out,then desolder all 3 wires on the back of the meter.Loosen the 3 screws on backside.Now.it is possible to move all backwards out. It is very good taightened.Principle:The end cover with 3 screws press a "o" rubber-ring out to the corner of the iron-cylinder, lock and seel it.This way you may change the front glass if it is broaken.
