|R-107, R-107T, R-107D, R-107M
The R-107 transceiver is one of the newest additions to Soviet communications. It is a
man-packed frequency modulated transceiver which operates with in a frequency range of of
20 - 52 MHz. encompassing 1,231 useable frequencies ( Channels. ) This radio uses two
bands, Band One is 20-36 MHz and Band Two is 36-52 MHZ. The set is capable of using the
standard Kulikov antenna, a combined rod ( 2.7 meter ) or a travelling wave ( 40 meter
doublet ). It has both continuous tune and pre-set capability with up to four pre-set
frequencies. Power for the set is supplied by two rechargeable KNP-20 2.4 volt batteries.
The R-107 is a sturdily constructed radio with a working weight of 16.9 Kg ( 37.2 lb. )
set has a power output of 1 watt and a range of 6 kilometres ( 3.75 miles ) with a whip
antenna 6-8 Km ( 3.75 - 5 miles ) with a combined rod antenna and 12 - 25 Km ( 9.4 to 15.6
miles ) with a travelling wave antenna. The set can be used as a radio relay station and
can be remoted by using the standard field telephones, the TAI 43 or the newer TA 57. The
set is designed for communications up to company level. This set operates in the same
frequency range as the AN/PRC 25, AN/PRC 77 and the AN/VRC 12 and can be netted with these
radios. This set is replacing the R-105M series of radios.
It was developed after the R-105M series at the same time as the R-123. That would make
it mid to late 70s. In general they are 20-51 MHz FM man-pack. There are at least 4
versions. R-107 ( tube and solid state versions ), R-107D ( LED digital
frequency readout ).
R-107M (latest and weird variant of R-107): power output is 5W, modulation is FM
or CW, a Morse key can be attached to the top of transceiver.

R-126 Manpack Transceiver
|R-126 Man-Pack Transceiver
It is used by Motorised rifle platoons and companies. It covers 48.5 to 51.0 Mhz, is
capable of Voice and is FM. It has a range of 2 to 4 Km, a power output of 0.5 watts, and
has continuous tuning or a choice of three pre set frequencies.
R-129 Man Pack Transceiver
|R-129 Man Pack Transceiver
The R-129 is a ruggedly constructed, man packed transceiver which operates from two 2.4
VDC batteries hooked in series. The set is 18.7 x 40,0 x 33.7 cm and weighs 19 Kg. The
front panel contains the dials and switches which operate the transceiver. The set can
easily be recognised by the power switch's location on top of the radio. The R-129 can can
transmit and receive in Single Side Band ( SSB ), Amplitude Modulation ( AM ) and
continuous wave, ( CW ). It can also transmit but not receive Frequency Shift Keying ( FSK
The set operates from 1 to 10.999MHz. It has detent tuning with a 10 KHz channel
spacing. The power output is 3 to 90 watts and has a range of from 10 to 300 Km. The
antennas that can be used with this set are a 1.5 meter whip antenna and a Dipole Antenna.
The set can be remotely operated from up to km distant with the use of the new TA 57 field
The limitations of this set are that it is difficult to repair as the components are
hard soldered to the chassis rather than being modular plug in units. Because of its
weight it is difficult to man-pack. As it has no speaker, headphones must be used. When in
the mobile mode, the set is capable of only 8 hours continuous receive operation before
recharging the accumulators becomes necessary.
