channel started up, but wasn't broadcast from Huntshaw Cross until summer 1985. Second Quarter 1983 - March 1997 405 line television was discontinued early, and for the next 14 years only the four primary analogue UHF channels were radiated. March 1997 - 1 November 1998 The fifth UK analogue UHF channel was added. Analogue and Digital television 1 November 1998 – 1 July 2009 The initial roll-out of digital television involved running the digital services interleaved (and at low ERP) with the existing analogue services. 1 July 2009 – 29 July 2009 Digital Switchover started at Huntshaw Cross. The analogue BBC2 service on channel 62 was switched off, along with the BBC Mux 1 service on channel 54- and the new "BBC A" multiplex started up on the newly vacated channel 62 at full post-DSO power. Digital television 23 July 2009 – 30 September 2009 All the remaining analogue TV channels were shut down and the new post-DSO digital multiplexes for the PSB channels started up at full power. Huntshaw Cross was subject to a complex multi-stage switchover, and the COM multiplexes (Mux A, Mux C and Mux D) were not switched from their pre-DSO configurations immediately. 30 September 2009 – 28 March 2012 With the post-DSO retune event at Mendip, the post-DSO COM multiplexes replaced the pre-DSO COM multiplexes on their final channel allocations, though only the SDN multiplex gained full power at this point. 28 March 2012 - May 2013 With the second post-DSO retune event at Mendip, the Arq A and Arq B multiplexes gained full power. From May 2013 Yet another retune was needed in May 2013 as part of the Europe-wide tactic of clearing Band V above 800 MHz so as to make space for future 4G mobile phone services. The BBC A multiplex was reassigned to channel 50. From 19 June 2019 A retune will be needed from 19 June 2019 due to the 700 MHz clearance programme. The recommended television aerial for Huntshaw Cross will change from group C/D to group A.
