The operational evaluation of the  Radio Set conducted by the Army Concept Team in Vietnam considered use-of the equipment by special forces teams in the extremes of terrain environment normally encountered in Vietnam. The analysis of the data collected on the performance of the radio, indicates a communication reliability of 50 percent, which is at least as good as other equipment presently employed in performing the mission. While the Was not able to overcome many of the natural conditions which adversely effect radio communications in Vietnam, such factors as its lightweight, ease of . stallation and operation, and minimal maintenance requirements, provide significant advantages over existing equipment.
