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. ==Notable radio operators==
