24、-165. Change 4 1-2 TM 11-5820-759-12 Section II. DESCRIPTION AND DATA 1-4. Purpose and Use Radio Set AN/GRC-165 is a variable frequency single sideband (Ssb) radio set, capable of transmitting and receiving lower sideband (lsb), upper sideband (Usb), continuous wave (Cw), and amplitude modulation (A

25、M) signals to be used in mobile, transportable, or fixed installations. The radio set can be operated on any frequency assigned in the 2- to 15-megahertz (MHz), high frequency (hf) range, and provides an output of 100-watt peak envelope power. The radio set has been designed for rugged service and h

26、as a splashproof case. Compactness, high reliability, and moderate power consumption result from the maximum use of transistors and other solid-state devices. Digital frequency selection is provided for both receiving and transmitting. When used with Control, Radio Set C7648/GRC165, keying and audio

27、 functions of Radio Set AN/GRC165 can be remotely extended to distances of up to 92 feet (29.04 meters) (the length of Cable Assembly, Special Purpose, Electrical C-10823/U) from the radio set. 1-5.
