The Telegraph newspaper reports on Maritime Radio Day, held to commemorate the day the RMS Titanic started to sink, April 14, 1912.
Radio was vital in aiding the rescue of those who survived, and Maritime Radio Day celebrates a global telecoms service based on voice communication and Morse Code.
Its history ranges from its inception on the world’s oceans in 1900 through to the arrival of the advanced Global Maritime Distress Safety System (GMDSS) in 1999, which brought a degree of digital automation to the service.
Marine telecoms services use shortwave radio frequencies, because these signals can bounce between sea level and the ionosphere high above the Earth – which allows modestly powered transmitters to achieve global range.
