Quiet Operation of AN/PRC-77 Radios

Abstract

Operation of tactical radios in enemy territory is frequently restricted by the need to maintain voice silence. The U.S. Army Land Warfare Laboratory developed techniques for accomplishing this by use of acoustic masking devices, supplemented by electronic amplifiers to permit whisper modes of operation. Tests confirmed that these approaches provide silencing; voices could not be detected beyond three feet from the source. Further development is required only to militarize the devices.
