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.
Antenna for the radio was length of wire in 12 meters
long. The wire could hang up at any object (for example, at tree).
There were two counterpoises, 3 and 12 meter long each.
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.”
