The South Caradon Copper Mine, 1 km to the SW of the transmitter, was the largest copper mine in the UK in its heyday, 150 years ago. Many other copper, tin and granite mines are scattered around the base of the hill.

History

The station was built in 1961 by the Independent Television Authority to bring ITV to South West England for the first time. Inaugural broadcasts were from the ITV franchise holder for the area, Westward Television. 405-line monochrome transmissions were on channel 12, Band III VHF. The station was also the first in the area to broadcast television using Band III.

In 1969 it was chosen to become a main station in the new colour UHF television network, broadcasting BBC One, BBC Two and Westward Television. Both the UHF and VHF services continued in tandem until 1985, when VHF television was discontinued in the UK.

In 1992 Caradon Hill (along with Redruth) was chosen as the site of the first commercial radio broadcasts in Cornwall, with Pirate FM taking to the air on 11 March of that year.

Coverage

Caradon Hill covers east and central Cornwall, from Truro and Falmouth in the west to Plymouth and Bude in the east. It also reaches into west Devon, as far as Barnstaple, Okehampton and Salcombe.
