ABSTRACT
Radio regulations are required to ensure that those who need or wish to use radio can do so without causing and suffering from undue interference. The regulations regarding use of maritime radio are set out in the Radio Regulations, as published by the International Telecommunications Union. The international Radio Regulations require that any vessel carrying maritime radio transmission equipment must be licensed. Licensing ensures that maritime radio equipment does not cause undue interference with other communications equipment and is operated by competent persons. A ship radio licence is required if maritime radio equipment is available for use on board a vessel. The Hydrographer of the Navy publishes information of interest to users of the maritime radio service in six volumes. The testing of compulsorily fitted radio equipments is governed by regulation. The radio apparatus on UK ships shall comply with the requirements of the Ship Radio Licence and the relevant Ofcom Performance Specification.
