Radio set SCR-131 is a portable, loop, continuous wave (CW) telegraph transmitting and receiving set operating within a frequency band 3,960 kHz to 4,360 kHz. The set is designed to give reliable communications between headquarters which are separated by a distance of 5 miles or less. It is also designed to furnish 40 operating channels spaced 10 Khz apart; however, in order to avoid possible interference between nets it is desirable so to assign frequencies as to have nets which operate withing 5 miles of one another spaced at least 20 kHz apart. The set required only two men to carry it. When set up, it occupies little space and can be used in any location from which satisfactory radiation may be expected.

Radio set SCR-161 is identical with radio set SCR-131 except for the capacitances of three capacitors, which difference causes the former to operate within a frequency band of 4,370 to 5,100 kHz. It is designed to furnish 74 operating channels spaced 10 kHz apart.
