Frequencies for the Global Maritime Distress and Safety System (GMDSS)

Since its inception, radio has been used to save lives at sea. After the tragedy with the Titanic, the International Conference on Safety of Life at Sea (SOLAS 1914) decided that ships with more than 50 people on board should “be fitted with a radiotelegraph installation” to maintain a radio watch at a frequency of 500 kHz. The First World War did not allow these plans to come true. Only SOLAS-29 obliged to introduce a radio watch in the MF range at a frequency of 500 kHz using Morse code on passenger and cargo ships of 1,600 gross registered tons or more.
