Mynydd Pencarreg transmitting station

The Mynydd Pencarreg transmitting station is a broadcasting and telecommunications facility located on high ground about 10 kilometres (6.2 mi) south of Lampeter, in Ceredigion, Wales. The site has a guyed 99 m (325 ft) lattice mast erected on land that is itself about 410 m (1,345 ft) above sea level. It was originally built by the GPO as a telecommunications relay, and (amongst other things) was responsible for handling the microwave feed carrying the now-defunct 405-line VHF BBC television service to the television transmitter at Blaenplwyf about 35 kilometres (22 mi) to the northwest near Aberystwyth. Despite this, Mynydd Pencarreg was never a 405-line TV broadcast site.

Broadcast UHF television was added to the site in early 1981,[1] launching with just the three programme services that were active at the time. S4C was added in 1982 when it launched.

Currently, the transmitter provides DVB-T digital television to the Lampeter area, along with FM radio.

The UK's digital switchover commenced, mirroring the changes taking place at the parent transmitter at Preseli. Analogue BBC Two Wales closed on channel 64 and ITV1 Wales took over on that frequency for what would be its final 3 weeks of service, vacating channel 61 as it did so. The new digital BBC A multiplex started up at full power in 64-QAM mode on channel 61.
