USSR VHF AM transceiver type R-106

The USSR type R-106 VHF AM manpack transceiver was developed in the early 1950s. The sets were used for communication within Company and Battalion, eventually replaced by the R-105D, R-108D and R-109D series. Operation of the R-106 is extremely simple as there are no controls except the channel selector and push to talk switch.

• Frequency range 46.1 to 48.650 MHz (18 channels of 150kHz)
• RF output approximately 0.75W
• Range about 1.5 kM
• Modulation AM R/T only.
• Receiver is a superheterodyne with 7.3MHz IF/superregenerative detector.
• Manpack antenna is a 1.6M Kulikoff type.
• Other antennas include 150ft Beverage type.
• The Kulikoff antenna socket is mounted at the back of the set
• Antenna may be stowed in the canvas pocked along the lower edge of the back of the set
• Powered by 2.4V NiCad battery
• 2.4V filament battery valves are used.
• HT is obtained from an internal vibrator unit.
