Abstract:

A requirement exists for speech communication by radio between parachutists, e.g. student and instructor, during free-fall training. Such equipment must be very compact, and provide fully hands-off operation, using voice-controlled changeover from receive to transmit. Prototype transceivers have been developed using sub-assemblies from ANPRC-90 equipment with an added voice-control module. The equipment and its trial results are described and considerations relating to possible production are discussed. Author
