BBC Radio Scotland
BBC Radio Scotland is a Scottish radio network owned and operated by BBC Scotland, a division of the BBC. It broadcasts a wide variety of programmes. It replaced the Scottish BBC Radio 4 opt-out service of the same name from 23 November 1978. Radio Scotland is broadcast in English, whilst sister station Radio nan Gàidheal broadcasts in Scottish Gaelic. The first BBC Radio Scotland broadcast was on 17 December 1973, two weeks earlier than planned. BBC Radio Scotland was founded as a full-time radio network on 23 November 1978. Previously it was possible only to opt out of BBC Radio 4, and the service was known as Radio 4 Scotland or, formally on air, as BBC Scotland Radio 4. The establishment of a separate network was made possible when Radio 4 became a fully UK-wide network when it moved from medium wave to long wave and new VHF (FM) transmitters were brought into service so that Radio 4 and Radio Scotland no longer had to share on FM. However it was not until the early 1990s that Radio 4 was available on FM across all of Scotland so for its first decade on air, the station only broadcast during the day so that Radio 4 could be heard on Radio Scotlands transmitters in the evening to compensate for poorer AM reception after dark. Kirsty Wark launched her career on BBC Radio Scotland, first as a researcher and then as a producer.
