The Caerhendy television relay station was sited at Caerhendy in the Afan Valley, a few kilometres north of Junction 40 on the M4 motorway at Port Talbot. It was originally built in the 1980s as a fill-in relay for UHF analogue television. It was sited at the clubhouse of the soccer ground at Ynys Park and consisted of a mere 3 m aluminium mast carrying a vertically stacked yagi array. The transmitter served about 50 houses in Caerhendy, about 500 m across the valley to the east, which for reasons of geography couldn't get a signal from Mynydd Emroch transmitter just to the south.

Alltwen transmitter re-radiated a signal received off-air from Cwmafan about 2 km farther to the northeast, itself a relay of Wenvoe. It was possibly the lowest ERP officially provided TV relay in the UK, radiating just 0.5 W on each of its four UHF channels.

When it came, the digital switchover process rendered Caerhendy redundant. It is no longer in service.

gollark: I quite like the FP style, but Lua makes it annoying, so I'm looking at making a FP/general convenience lib for potatOS.

gollark: The main large thing I work on is potatOS, which someone wanted me to rewrite in amulet, but that would be impractical as it's quite large and not really programmed in a very functional style.

gollark: My stuff is mostly designed as "insanely weakly typed with minimal sanity checks", while most of the CC standard libraries/programs go for "have some type checking on function arguments".

gollark: Oh, right. I assumed you meant it would make `type` return that, but I don't think CC has that implemented.

gollark: No, I mean I don't think it does anything.
