Digital switchover

Digital switchover began at Caradon Hill in the early hours of 12 August 2009. At approximately 1.15am the analogue BBC Two signal was switched off. The other analogue signals (BBC One, ITV and Channel 4) along with digital Multiplex 1 were then temporarily switched off in sequence. Between one and two hours later the analogue BBC One, ITV and Channel 4 signals were restored in sequence along with Multiplex 1 which was moved from UHF 34 to UHF 28 – analogue BBC Two's frequency. The rest of the analogue signals were switched off permanently just after midnight on 9 September 2009. Once the digital signals were reshuffled to take advantage of the space left by the switched off analogue signals, they were then brought up to full power (digital signals were broadcast at a much lower power pre-switchover). This completed Caradon Hill's switchover to digital. This also completed the West Country region's digital switchover.
