The AN/PRC-74 is a low-power, transistorized, SSB radio set used for voice and CW communications. It is designed primarily as a manpack set in areas where direct line of sight (LOS) communications are not possible. Except for the difference in the frequency range of the AN/PRC-74B and AN/PRC-74C, all models are essentially the same. Current tactical speech security equipment is not compatible with the AN/PRC-74; therefore, secure voice is not a mode of operation. Coder-Burst Transmission Group AN/GRA-71 can be used with all lettered models.
