27、. DESCRIPTION AND DATA 1-4. Purpose and Use a. Purpose. Radio Set AN/PRC-47 (fig. 1-1) is a high frequency radio communications system. The radio set primarily provides 10,000 channels of upper sideband (usb) voice transmission and reception, continuous wave (cw) telegraphy, or frequency shift keyin

28、g (fsk) teletype in the 2.000- 11.999-mHz frequency range. The radio set can be operated from its own control panel or con- trolled by a remote power control panel, such as Control Group AN/GRA-6, for at least a 2-mile distance. b. Use. Radio Set AN/PRC-47 is used for two-way high-frequency (hf) rad

29、io communications. It is nor- mally used in the portable (man carried) configuration, but can be vehicular-mounted or used as a fixed station, such as in a shelter. In the portable configuration, one member of the two- team carries the receiver- transmitter, and the other member carries the battery pack and accessories. When the radio set is vehicular- power is supplied from the dc vehicular
