Description of Radio Set ANIPRC-6 (fig. 2) Radio Set AN IPRC-6 is a 13-tube, low-power, portable radio set use

17、d for voice communication over short distances. The major components of the radio set are Radio Receiver-Transmitter RT-196 (*) IPRC-6 and Handset H-33 (*) IPT (fig. 2). The radio receiver-transmitter may be operated without the handset. Battery BA- 270IU is required for operation burt is not a comp

18、onent of Radio Set ANIPRC-6; it is issued separately. Note. Throughout this manual, Handset H-33 C) /PT refers to Handset H-33C/PT or H-33D/PT; and Radio AGO 1426A Receiver-Transmitter RT-196(*)/PRC-6 refers to Radio Receiver-Transmitter RT-196/ PRC-6 or RT- 196A/PRC-6. The differences in models are

19、 minor internal differences. The different models of the equip- ments are similar in appearance, and the operation and organizational maintenance of the equipments are the same. a. Radio Receiver-Transmitter RT-196 (*) 1 PRC- 6 (fig. 3). Radio Receiver-Transmitter RT-196 (*) IPRC-6 is commonly refer

20、red to as a handie-talkie. It resembles a hand telephone (fig. 2) and may be held in either hand when operating. The handie-talkie consists of a re- ceiver-transmitter chassis with vacuum tubes; a cover or shield for the receiver-transmitter chassis; a microphone and earphone (fig. 2) ; a flexible s

21、teel whip (vertical) antenna; and a two-piece cast-magnesium case held together by four lever-type latches (two on each side of the case). The receiver-transmitter chassis, the microphone and earphone, and the space for the battery are contained within the magnesium case. All operating controls of t

22、he handie-talkie are mounted on the outside of the case. When the antenna is being used, it is mounted to a connector on the outside ofthe case. When the antenna is not in use, it is wrapped around the case (A, fig. 14). An adjustable strap is at- tached to the outside of the case. The operator can

23、use the adjustable strap as a shoulder strap or sling for carrying the handie-talkie on his back (fig. 1) or for additional hand support when operating the handie-talkie (fig. 22). b. Handset H-33 (*) IPT (fig. 2). The handie- talkie may be operated without the handset; the handset pelmits the opera

24、tor to use the radio set when the handie-talkie is carried on his back (fig. 1). The handset consists of a microphone and an earphom contained within a molded plastic case; and a 5-foot cable with a plug on the end. When the handset is used, the plug is connected to a connector on the case of the ha

Use of Radio Set (fig. 4) Radio Set AN / PRC-6 is used for voice com- munication over short distances. The radio set is designed to send (transmit) or receive fre-

26、quency-modulated (fm) radio signals on any one of 43 operating frequencies (channels) within the frequency range of 47 to 55.4 mega- cycles (me). The same operating frequency is used for transmitting and receiving. Figure 4 4 lists radio equipments and the operating fre- quencies that can be used in

Operating fre-Any one of 43 operating quency. frequencies or channels (figs. 4 and 12) can be used for transmitting and receiving. Only one operating frequency can be used at a time. Crystals required _ .A crystal located

29、 on re- ceiver-transmitter chas- sis (operating crystal fig. 10), is used to control AGO 1426A operating frequency of radio set. For operation on 43 channels, 43 crys- tals (one for each chan- nel of radio set) are re- quired (par. 7b). Only one crystal can be used at a time. Note. When shipped from

30、 factory, Radio Set AN /PRC-6 is tuned for an operating fre- quency of 51 me.
