Welcome to the russian section !

and other Comm Block countries


US-P Receiver


War time Russian Aircraft set, also used in other services. 150 kHz to 12Mhz, with bfo, 8 valved superhet.


RSI-4T


RSI-4T receiver, part of the 9R Russian tank set. This is a 6 valve AM only set tuning 3.4 to 6MHz.
Of course, I now have the rx, I now need the rest of the kit, transmitter, psu etc.
Either the transmitter as pictured below left or the combined tx and psu as pictured below right. If you have either available, please get in touch.



P-159 and RF-10


Additions here, P-159 VHF set and a RF10 vhf set.
The P-159 transistorised simplex VHF FM Russian Soviet Warsaw pact radio for moderate terrain. Used by frontier troops and national-guard units. It covers 30 to 74.999 MHz, with an output power of 5 W and a range of 10 to 50 km. The R-159 has a 16 kbits/s data capability, and a 500 m remote-control facility. Operating temperature is -40 to +50°C. Part of the communications family of the Russian BTR-80K APC Command Post vehicle (two sets). Approx 11 1/2" x 4" x 15 1/2". Morse key to top. Complete with headset and antenna.

rf10a rf10b rf10c
Manufactured by TESLA from Pardubice, the RF-10 is a compact VHF (44~54MHz) military transceiver that was used by the Czech army. It is a fully transistorized solid-state design employing modular construction & frequency synthesis. The receiver is quite sensitive at 0,5uV with 1W transmit RF output - a good compromise between battery consumption and range. It runs from a 6v 4Ah NiCad battery pack whose cells will probably need replacing. The top of the battery pack is secured by screws which when removed, allows easy access to the cells. Operation is very simple. Three knobs select operational frequency which is directly read out in the three small windows. The mode switch has 6 modes – Off, Whisper, Low Volume with Squelch, Medium Volume with Squelch, Hi Volume without Squelch & Battery Test.

P-128M


This is the P-128M Beacon set, dropped with cargo on a parachute and sends out a signal which can be tracked or DF'd by troops etc. The set could have the whip mounted on it or, using an adaptor plate, mounted higher up for increased range in poor terrain.

..........................................................................................................................................Right is view through tuning window showing set goes upto 50Mhz.


Pictures showing the carry bag open and closed.

P-24


This little set is a single channel HF receiver, used it is believed by the Bulgarian Special Forces. Kit came in a nice carry bag with whip antenna, earphone, long wire antenna, spare battery pack and small case holding 4 of the plug in frequency units.


The channel is selected with a small plug in unit, pictured left. Right is a unit cut open revealing a crystal, an intergrated circuit and coil and capacitors. For the marked 4048 kHz the crystal is 14.748 MHz, giving an i.f. of 10.7 MHz. I replaced xtal with one giving me an 80 Mtr frequency and there is no difference in sensitivity so it might have a wideband front end.


P-407


Other recent additions here, P-407 VHF set, around 50 to 60MHz with rebroadcast facility and connection for a land line, and a Russian DF set, Long Wave, still to be identified.
Soviet R-407M was developed as single channel full duplex radio-relay for either 2 or 4 wire connection. It was primary used in combination with other communication equipment either as an emergency link or during set-up of a station. The equipment is valved throughout. Frequency range 52-60MHz. RF 1 Watt. Mod FM R/T only. Channel spacing 50kHz. Powered by two sets of 2.4V NiCad batteries. AF bandwidth 0.3-3.4 kHz. Ringing tone 30-50Hz.


P-143


Recent addition, P-143 HF manpack, SSB/CW/AM. Similar role to the Syncal 30 etc.
R-143 , also called "Bagulnik" comes from the former UDSSR. It is a modern, solid state portable HF transceiver, used in many ways- also by special forces and as spyradio. There are R-143 with foreign lettering. Modulation: AM, CW, SSB. HF output: 10 W Channel spacing: 1 KHz. Frequency control: Synthesizer. Sensitivity: 2 uV / 20 db. Powered by: 12 or 24 V. Measuremants and weight: 350 x 310 x 105 mm; 11 kg.

RBM-1


Russian RBM-1 transmitter receiver. Still awaiting a good cleaning though. Covers 1.5 to about 6 MHz, AM and CW, 0.3 and 1Watt, needs 200v for tx, 80v for rx and 2.5v for heaters. Now working with a battery pack, 589 from PA0 with 100ft long wire.

10RT-26


10rtrxtx
10rk 10rttx
Tank set, this is a post war version of the 10RT war time set, 10RT-26, receiver, transmitter and psu. Tunes 3.75 to anbout 6MHz, runs of 26v, either continuos tuning or two xtal controlled channels, the small black oblong things bottom right of rx are the xtal units.

13-P


WW2 set, model 13-P (note: symbol "P" in Russian is equiv to a R in English). Similar to Brirish WS18 but this set uses a single valve in the tx, an SO-257. Batteries housed in the lower part of the case.

RIGHT: The P-107M manpack set.
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. This radio uses two bands, Band One is 20-36 MHz and Band Two is 36-52 MHZ. The set uses the standard Kulikov antenna, a combined rod ( 2.7 meter ) or a travelling wave ( 40 meter doublet ). It has both continuous tune and up to four pre-set frequencies. Power for the set is supplied by two rechargeable KNP-20 2.4 volt batteries. The R-107 weight of 16.9 Kg. The set has a power output of 1 watt and a range of 4 miles with a whip antenna, 5 miles with a combined rod antenna and 16 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 set is designed for communications up to company level.
