and other Comm Block countries
RS-41 Transmitter, R-4 Receiver
This Czech set, HF, 100W, 60's to the 70's. Tx on left, RS-41 with rx R-4 on right. Other kit and spares below.
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.
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
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.
