However, at the second stage of switchover, BBC A at both transmitters will move to a new final channel allocation of channel 50 (not channel 62).
The Digital 3&4 and BBC B multiplexes are unaffected by this change, and will use channels 59 and 55 respectively from the second stage of switchover. "
This is due to C62 being part of the Digital Dividend Review sale, and ensuring that the channel is reallocated at switchover on Wednesday, 13th April 2011, will ensure that viewers using Dallington Park and Luton will not have to retune at a later date.
Unfortunately because this is a wide Excel workbook exported as portrait PDF, the notes are truncated, so I don't know what's happening at Lark Stoke between 23 March and 6 April. Would be useful to know! (RG47SH)
I've received a copy of the spreadsheet by email which I will forward on. The Lark Stoke note I referred to earlier is actually completely wrong - I believe it should be a reference to Mux B moving to C21 between DSO1 and DSO2. Maybe an earlier plan had Lark Stoke switching two weeks earlier?
There is a note on the Lark Stoke page "BBCB will operate on channel 21 between the first and second stage of digitalswitchover [correction from "BBC" in Ofcom document]" which I got from the Ofcom press office when I rang them with a list of questions.
The spreadsheet notes that Com6/ArqB is going to be on C60 until 28th September 2011.
Brian: I think you've already entered a few of these changes, but in case it helps, here's everything that seems to have changed or that you don't have on the site already. I've put a # where there's a proposed move to a channel that will be released.
Caldbeck: SDN restricted to 15 kW at 598.5m until further notice. (PSB aerial is 619.5m) ArqA and ArqB are listed with this as the licensed height.
Moel-Y-Parc: SDN restricted to 2.5kW until 3 October. ArqA restricted to 2.5kW until 5 October. (DSO Details says September, 3 Oct is a Monday so I think 5 Oct is more likely.) ArqB subject to a reactive power restriction of 5kW until further notice.
Mendip: ArqA increases from 10kW to 12.5kW on 28 September. (We knew it got an increase, but not how much. This is when it changes to 64QAMmode and loses its current +167kHz offset.)
Emley Moor: ArqB subject to reactive power reduction of 87kW if required 'until further notice'.
Chesterfield: ArqA and ArqB restricted to 40W until 12 October.
Sheffield: ArqB starts on C63 at DSO 2 (24 August) at full power (1kW) and moves to final channel (this has C49, DSO Details has C39) on 27 September (which is a Tuesday: should be 28 Sept? DUK also has 27th.)
Sandy Heath: D3&4 and HD use transitional S1 antenna until 27 June 2012.
Sudbury: ArqA starts up at DSO 2 (20 July) at 3kW, replacing Mux C on C54 at 1.5kW, 'until further notice'. ArqB starts up at DSO 2 at 2.2kW replacing Mux D on C50 at 1.1kW, moves to C63 (at 2.2kW) on 16 November.
Clacton: Claims BBC A starts up on 6 July on C49 - which is the allocated channel. DSO Details has C48 from 6 July until 2012.
Hannington: ArqA restricted to 20kW from DSO 2 'until further notice'. ArqB starts up on C41 (final channel is C47) and restricted to 20kW. (Good old Ofcom, C41 is allocated to SDN at this transmitter and there's no note. DUK shows final channels at DSO 2 but does show two 'COM late power up' events.)
Midhurst: ArqA subject to a reactive power restriction to 5kW 'if required' 'until further notice'. ArqB restricted to 1kW 'until further notice'.
