The Mynydd Pencarreg transmitting station is a broadcasting and telecommunications facility located on high ground about 10 kilometres (6.2 miles) south of Lampeter, in Ceredigion, Wales.

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 miles) to the northwest near Aberystwyth.

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.

The UK's digital switchover commenced, mirroring the changes taking place at the parent transmitter at Preseli.

OFCOM have announced that channel 61 is also to be cleared so as to make space for future 4G mobile phone services.
