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.
Recent addition, P-143 HF manpack, SSB/CW/AM. Similar role to the Syncal 30 etc.
Around 20W or so from 2 12v batteries, one used on rx, both switched in for tx.
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 foir rx and 2.5v for heaters.
WW2 Tank set, 10RT26 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.
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.

Produced in the Nizhny Novgorod Radio Works and others Russia plants
LEFT: A Russian P-147, paratroopers set, small, vhf, very cute !! Runs off a couple of 9v batteries, around 50MHz.
RIGHT: P-311 hf rx. R-311("Omega").AM/CW, coverage 1 to 15 MHz in five ranges. Model about 1960-70. Aleksandrov Radio Works, SU.
P-109
P-105
The Russian low band vhf FM sets, P-109 and P-105. Soviet (Warzaw Pakt) army radio transceiver R-109m. Model about 1964.
(10 tube, 5 transistors). Made in "Post Box B-8865" plant, Voronezh or Aleksandrov Radio Works. Russia.
The hf receiver, P-326. Operation is a little difficult, not a nice rx to play with
P-104
P-123
P-104 HF transmitter receiver, based on a German design I believe. Nice to operate.
The P-123 tank set, solid and indestructable. FM-transceiver R-123M. Used in tanks and armored vehicles, or together
with P-105M, 108M, 109M, 113, 114, 126 etc. Operating modes: voice transmission, duty reception. Coverage frequency
20 to 51,5 MHz in two ranges. 14-28 km comunication range in moving mode and max 70 km range fixed. Tuning is the optical
system, where the frequency display is reflect to a glass plate. Manufactured in Sarapoul, Voronezh Radio Works and
probably in others USSR Radio Works too.
LEFT: The (R)P-107 VHF transceiver. There were valve and transistor (P-107T) versions of this set.
RIGHT: The P-107M manpack set.
LEFT: A Czech made hf transceiver, the RM-31, a very nice set to use. Strange key though, you need to pull the tapper UP to switch between tx and rx. It took me hours to figure this trick out !
RIGHT: RF11 set, complete in its box.
The R-1262, Fig. 5, is a 4 channel 30 to 80 MHz VHF FM receiver weighing just 350g and measuring 128 by 70 by 30mm.
The set came with its headphones, two clip on 9volt rechargeable batteries and a small handbook containing a
block diagram and operating instructions. The actual country of origin is not known but the handbook is written in Hungarian.
The set might be Hungarian made or from the Comm Block collective. The receiver is a double conversion design,
10.7 MHz and 455 kHz intermediate frequencies. The set came fitted with 4 channels, around 33, 42, 70 and 71 MHz.
the rf section of the set automatically tunes to match the crystal selected.
