hi and stuff SCR-108 The SCR-108 Radio Truck was a mobile Signal Corps Radio used by the U.S. Army during and after World War I, for short range air to ground communications,
Contents
Use
This truck was assigned to squadron headquarters in order to communicate with the SCR-68 airplane radio as well as the others in its class. eventually replaced by the SCR-197 mobile radio station. The van is described as having room for 3 operators and one squadron radio officer. One bench supports the SCR-67, SCR-54, and 1 amplifier with storage batteries held by clamps underneath the bench. on another bench is the SCR-79. a desk for the officer is installed with batteries underneath. a 6 volt circuit is provided for 2 lamps connected to storage batteries, and a 110 volt circuit with 2 lamps is provided if there is an external power source available.
Components
(Note- all sets seem to have been upgraded to an A model)
- SCR-54 Receiver- (BC-14), Crystal detector; inductively coupled; tuned primary and secondary; 150 foot inverted L antenna; wavelength range, 200 to 600 meters.
- SCR-67 Radiotelegraph- (BC-13), transmitting and receiving; for ground stations; has 1 oscillator, 1 modulator, 1 detector, and 2 amplifier vacuum tubes; wavelength range transmitting 250 to 450 meters, and receiving 200 to 600 meters.
- SCR-79 Radiotelegraph- (BC-25), transmitting and receiving; consists of an electrostatically coupled vacuum tube oscillator circuit for transmitting, and a vacuum tube detector and 2 stage amplifier for receiving; requires a low resistance antenna. wavelength is 500 to 1.100 meters
- SCR-121 Amplifier- (BC-44), 2 stage vacuum tube audio amplifier using iron core transformers
Variants
The SCR-124 was evedently housed in a similar truck, and was assigned to division and Corps level headquarters. it carried the following components-
- SCR-99 Radiotelegraph
- SCR-121
- SCR-54
- SCR-82 battery charger (replaced by SCR-110)
- SCR-79.
- SCR-97 Radiotelephone
