Abstract : The AN/PRC-44(XN-1) is a uhf radio system designed to provide two-way voice communications between personnel roving the flight deck and a fixed command center in the island of an aircraft carrier. The PRC-44 components consist of a transceiver and battery worn by the roving personnel at the waist, and a cloth helmet with earphones in muffs featuring liquid-filled cushions and a boom-mounted microphone (noise cancelling, dynamic). The nonwearable components provided are a receiver for use in the island and a battery charger. Acoustically, the PRC-44 is a good system; speech is intelligible when both talker and listener are in 125 db jet noise. The packaging around the waist is too bulky, mainly due to the large battery that the vacuum tube, uhf circuitry requires. A major deficiency of the PRC-44 system is that it is not designed to handle communications from one man on the flight deck to another, although 18 per cent of the messages in flight deck operations are of this kind.
