Ferryside television relay station is a small TV relay in the village of Ferryside, Carmarthenshire, Wales (). The Ferryside relay is fed with the off-air signal from Preseli about 17 miles (28 km) to the northwest. It is one of the few UK broadcasting transmitters using a wooden pole as aerial tower. It was built in 1985 partly to provide a stronger signal to Ferryside itself, but also to lower Llansteffan on the western side of the estuary which could not receive a usable signal either from Preseli nor from Carmel about 14 miles (22 km) to the northeast. Digital switchover The Ferryside relay is unique because it was chosen as the site of the UK's experimental switchover trial, and as such became the first UK TV transmitter to be converted to digital, complete with the loss of the old analogue TV signal. This mimicked what would actually start to happen later in the decade as the analogue TV signals were progressively turned off in favour of DVB across the country as whole. At the end of 2004, the relay was equipped to provide the four primary DTT multiplexes (Multiplex 1, 2, A and B) and after a three-month period, all local residents were given Freeview boxes. Three of the four analogue services were switched off at midnight on 30 March 2005. Only BBC Two Wales analogue remained. There had reportedly been some local concerns, caused by the differing content of the BBC 2W digital service compared with BBC Two Wales analogue. BBC Two Wales analogue was finally switched off as part of the full digital switchover in the Preseli region which happened four years later between 19 August and 16 September 2009. Transmitted services Analogue television 1985 - 29 November 2004 The site came into service in 1985 with the full complement of four UK terrestrial analogue services in place from the start. Analogue and digital television 29 November 2004 - 30 March 2005 The Ferryside "digital switchover" trial commenced with four of the pre-DSO multiplexes from Presely being re-radiated in the gaps between the existing analogue TV channels. The BBC multiplexes were trialled with the ultra-low ERP of 1 W, the COM multiplexes with 5 W. 30 March 2005 - 19 August 2009 BBC One Wales, ITV1 Wales and S4C were all switched off in March 2005 and the four digital multiplexes took over on their final intended
