wireless operators
Signal transmission personnel
Wireless operators are people who transmit and receive radio communications, typically using Morse code or voice.
The term dates from early radio technology, when "wireless" distinguished radio from wired telegraphy.
Ship wireless operators sent distress signals; military operators relayed battlefield communications.
The role has largely been replaced by automated systems, though amateur radio operators still use the term: The wireless operator picked up a faint signal from the downed aircraft.
