The Llandyfriog transmitting station is a broadcasting and telecommunications facility located on high ground several kilometres east of the town of Newcastle Emlyn, Ceredigion, South Wales. It was built in 1980 to relay VHF radio and UHF television to Newcastle Emlyn and the area in general. The site has a 25 m self-standing lattice mast erected on land that is itself about 105 m above sea level and acts as an off-air television relay of Preseli, about 20 km to the west.

Since Winter 1981{{Cite web |url=http://www.bbceng.info/Eng_Inf/EngInf_7.pdf |title=Archived copy |access-date=2012-05-01 |archive-date=2009-01-06 |archive-url=https://web.archive.org/web/20090106072335/http://www.bbceng.info/Eng_Inf/EngInf_7.pdf |url-status=dead }} Llandyfriog has transmitted FM radio, acting as an off-air relay of Blaenplwyf about 50 km to the north.

==19 August 2009 - 16 September 2009==

The UK's digital switchover commenced, mirroring the changes taking place at the parent transmitter at Preseli. Analogue BBC Two Wales closed on channel 28 and ITV1 Wales took over on that frequency for what would be its final 3 weeks of service, vacating channel 25 as it did so. The new digital BBC A multiplex started up at full power in 64-QAM mode on channel 25.
