An advanced and unique marine radio design and state-of-the-art microprocessor technology were combined in an ARQ (automatic request for retransmission) marine telegraphy system. Among it's unique features; the system permits the use of a single shipboard antenna for transmitting and receiving; the ARQ terminal is interactive with the operator for simplicity of operation and testing, and is operated entirely from the teleprinter keyboard; and a no-wear solid-state transmit/receive switch avoids receiver degradation during the automatic ARQ transmitting and receiving cycles. The equipment design and the unique features developed for the system are briefly described in this paper. Some elaboration of the interactive terminal operation is given.
