The new BBC A multiplex started up at full power in 64-QAM mode on channel 60, and Mux 1 on channel 55 closed.

As a side-effect of frequency-changes elsewhere in the region to do with clearance of the 800 MHz band for 4G mobile phone use,^[2] Carmel's "Arqiva B" multiplex will have to be moved from channel 61 to channel 49 and the "BBC A" multiplex will get a negative offset.^[3]
