Radio operator
Person responsible for the operations of a radio system

A radio operator (formerly known as wireless operator in British and Commonwealth English), also referred to as radio officer, is a person who is responsible for the operation of a ship radio station and the technicalities aboard.
The profession of radio operator has become largely obsolete with the automation of radio-based tasks in recent decades. Nevertheless, radio operators are still employed in maritime and aviation fields. In most cases radio transmission is now only one of several tasks of a radio operator.
The role of 'Wireless Operator' aboard aircraft during WWII was often abbreviated to 'WOp' or 'WOP' in official documents or obituaries.
01History
Radio operators were indispensable at sea in the early days of wireless telegraphy, and many young men were called to sea as professional radio operators who were always accorded high-paying officer status at sea. Subsequent to the Titanic disaster and the Radio Act of 1912, the International Safety of Life at Sea (SOLAS) conventions established the 500kHz maritime distress frequency monitoring and mandated that all passenger-carrying ships carry licensed radio telegraph operators.
On board ships, radio operators were nicknamed "Sparks," in reference to the spark-gap transmitter which were installed in the early years of wireless at sea; the nickname stuck around long after the spark gap transmitters became obsolete.
