No. 1 dated June 1955.-- -ELECTRICAL AND MECHANICAL CHARACTERISTICSRadio Set AX/ VRC-2, 21FUNCTIONAL DESCRIPTIONThe AN/M(C-2 and AN/VRC-2X are completeradio sets, less primary power source, designedfor vehicular operation. It providestwo-way voice communication withsimilar fixedor mobile equipment operating at the samefrequency. The radio sets are preset for asingle output frequency (crystal controlled)in the range between 30 and 40 megacycles.Frequency modulation (FM) is used. Reliablecommunications up to a distance of 15 milesmay be obtained in open terrain.The communication circuit is of singlefrequency(receiver and transmitter tunedto same frequency), push-to-talk type. Thereceiver and transmitter are crystal-controlled,and other crystals must be substitutedinorder to change frequency. Thetransmittermust be retuned before signals at anotherfrequency can be received or transmitted.Operation of a push-ta-talk buttondisables the receiver and turns onthe transmitter.Conversation can proceed in one directionat a time. A single antenna is usedfor transmitting and receiving and it isswitched by an antenna relay located in thetransmitter.

10 August 1962 RADIO SET AN~WRC-ICog Service: FSN: Functional Class:USA USN USAFTYPE CLASS: Std StdMANUFACTURER'S NAMEICODE NUMBER: General Dynamics Electronics, (95~03).Radio Set AX/YRC-IFUNCTIONAL DESCRIPTION:The Radio Set AN/WRC-1 is designed as a communication transmitting and receiving system,requiring an automatic antenna tuning system for proper operat ion. The system consists of areceiver. a single sideband exciter, a junction box, and a power amplifier. The systemcovers the frequency rsnge of 2 to 30 megacycles [VC), and is capable of producing an outputof 100 watts peak envelope power (PEP). Transmission and reception on upper sideband (USE),lower sideband (LSB), continuous wave (cw). amplitude modulation (AM) and independent sideband(ISR) are provided. IqR allows the transmission and reception of different informat ion on USRand LSB simultaneously. Frequency shift keying (FSK) operat ion is obtained using suitableauxiliary equipment (not supplied).NO field changes in effect at time of preparation (31 May 1962).
