Services
It is the main television broadcasting station for the Borders area, and was the first high power main station in the United Kingdom to be upgraded as part of digital switchover. This upgrade was completed on 20 November 2008, when the analogue signal was turned off and replaced by high power digital television signals.
Selkirk also broadcasts a number of radio services, including local commercial station Greatest Hits Radio Scottish Borders and North Northumberland, national station Classic FM, and DAB multiplexes from the BBC and Digital One.
History
Selkirk was built by the Independent Television Authority (ITA) in 1961 in order to bring the commercial franchisee Border Television to south east Scotland, using the 405 line monochrome system on VHF channel 13.[2]
The other Border Television transmitter was the Caldbeck transmitting station, which opened in September 1961. Border Television started broadcasting on December 1 1961.[3] The first broadcaster was the announcer Mary Marquis.
405 line television was discontinued in the UK in 1985. 625 line UHF television was introduced at Selkirk in March 1972,[4] carrying BBC1, BBC2 and Border Television (ITV) . Channel 4 was added when it launched in November 1982, and Channel 5 was added in March 1997. Radio Borders started from Selkirk in January 1990, with Classic FM following in November 1996. The Digital One and BBC DAB services both commenced in October 2007. BBC national FM services are transmitted from neighbouring Ashkirk transmitting station.
