Digital television
Digital television replaced the analogue television signals during the digital switchover of April 2012. However, only 3 of the 6 multiplexes are available: BBC A & B and Digital 3&4.
BBC A launched on UHF 61 on 4 April 2012, before moving to its final allocation of UHF 49 on 18 April, when BBC B and Digital 3&4 launched. As part of the 700 MHz clearance programme the UHF channel numbers were changed in March 2018.[2]
