Torn. Fu. g

The Torn. Fu. g is a backpack transceiver introduced in 1942. It was mainly used by Panzer Grenadiers to communicate with command vehicles. Panzer Grenadiers were infantry troops assigned to protect tanks in battle, as tanks by themselves are vulnerable to infantry with anti-tank weapons. The Torn. Fu. g was used to communicate with the Fu 8 set based on Befehlpanzers (command tanks) and other armored vehicles such as the Sd.Kfz 251.

Torn. Fu. g is carried (dismounted) in a steel pack container with a small bag and carrying straps. The container has one carrying handle and three connectors for fastening on the carrying straps, two ring eyes on top and a strap with a clip for fastening the small bag. The whip antenna can be stowed on the outer large side under spring clips. The antenna socket is on top.

The container has on the operating side the transceiver with the clipped-on remote-control unit; on the accessories side are the battery, antenna base, four antenna rods, one antenna tuning coil, one pair of headphones and one key. The small bag carries throat microphone, remote control cable, counterpoise and one pair of headphones.

The transmitter and receiver have common tuning circuits; adjustment of frequency applies automatically to both so that communications must be on the same frequency (simplex). Tuning the antenna for transmitting automatically tunes it for receiving, but if transmitting is forbidden for security reasons, it is still possible to tune the antenna to receive.

Translated from "Die deutschen Funknachrichtenanlagen bis 1945 - Band 2 "Der Zweite Weltkrieg" by Fritz Trenkle

In 1942, the Torn.Fu.g was created with the frequency range of 2.5 - 3.5 MHz, and weighed 18 kg (compared to 21.5 - 23 kg of older devices). The dimensions were 39 cm X 33.7 cm X 18 cm. The two stages of the 1.5 Watt transmitter were equipped with RL2,4P3 vacuum tubes. The five-tube heterodyne receiver with local oscillator, mixer, and detector, had all stages utilizing 5 X RV2,4P700 tubes. The series produced in 1942 were primarily issued to Panzergrenadier regiments. The 1.5 meter "stab" pole-antenna was used. With operation during walking, a tube-form antenna tuning device was used between the transceiver and whip antenna. In stationary position, the following antenna elements were installed from bottom to top: an antenna base, tuning device, several "stab" or pole sections, capacitance umbrella. For power, a 2,4 Volt rechargeable battery was used along with a vibrating power supply. The maximum range of the device was 25 km (A1) and about 12 km (A3).

Another version of this device, the Torn.Fu.t was derived by adding a capacitor to the HF stage which changed the frequency range to 2.5 to 3.0 MHz.

(mHz) 2.5 - 3.5 mHz.



Sectional rod with umbrella (stationary); whip antenna when on the march.




One storage battery of type 2.4 NC 28 and a built-in vibrator unit WG1 2.4a. Battery capacity at a temperature above 0 Centigrade is about 15 hours, one-third of the time transmitting and two-thirds of the time receiving.

SCR-194, SCR-195 and SCR-300



Transmitter: 2 x RL2.4P3

Receiver: 5 x RV2.4P700

It is used by the battalion to company, company to platoon and lower echelons. It can be used in stationary positions or on the move.

CW and voice. Two-way communications on both CW and voice are possible both in stationary position and when on the move. With W/T it is possible to work "break in" operation.
