Radio changed maritime communication by allowing ships to send messages far beyond the range of flags or visual signals. Early systems used Morse code, where operators transmitted short and long pulses to pass messages between vessels and shore stations.
SOS became the international distress signal because its simple pattern was easy to hear and recognise, especially in poor conditions. Morse later gave way to voice communication over VHF, making fast coordination between ships far more practical.
