Soviet Spy Radio "Sever"

It was produced "Sever" and "Sever-bis." The radio differed by frequencies and a little in design. RX/TX for radio "Sever"- 3,62- 12,25/3,62- 6,25 MHz. RX/TX for radio "Sever- bis" - 2,22- 6,66/2,56- 5,77- MHz.

There were used anode and heater battery for feeding the radio. For high voltage there were used 4 batteries BAS- 60 (each battery has 60-V and 0.45A/H). For heater there were used 2 battery 3S (each battery has 1.5- V and 29.0 A/H). It was produced in small quantity radio "Sever" with feeding from the main.

Depending on the transmitting frequency a proper counterpoise was used. As usual, for low frequencies it was used counterpoise in 12 meter length, for high frequencies it was used counterpoise in 3 meter length. Counterpoise placed near one meter above the ground. Figure 2 shows the antenna configuration for the station. The radio could provide reliable communication (with a stationare radiocenter with special directed antennas and high sensitivity receivers) up to 700- km.

British spy Radio "Paraset"was the nearest analog of the radio "Sever."
