DDR changes for Luton and Dallington Park

The Luton and Dallington Park transmitters have a change of allocation for the PSB1 multiplex as part of the Digital Dividend Review sale.

The Luton and Dallington Park transmitters have a change of all
published on UK Free TV

From Ofcom:

"At both Dallington Park and Luton, the BBC A multiplex will operate on channel 62 between the first and second stages of switchover as previously planned.

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.

Brian: there are a number of other changes indicated in Ofcom's document at http://licensing.ofcom.org.uk/binaries/tv/sup_dso/version2.pdf. For example, at Andoversford BBC A will start up on C62 and move to C50 at DSO2.

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?

Mike Dimmick: Thanks for the spreadsheet.

There is a note on the Lark Stoke page "BBCB will operate on channel 21 between the first and second stage of digital switchover [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.

Border
------

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.

South West
----------

Huntshaw Cross: SDN, ArqA and ArqB restricted to 4kW until further notice. (No mention in latest DSO Details.)

Caradon Hill: ArqA antenna restrictions apply until further notice.

Stockland Hill: ArqA and ArqB restricted to 10kW until further notice (DSO Details has SDN as well, a number of notes relating to all COM muxes are missing from SDN's tab.)

Wales
-----

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.

West
----

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 64QAM mode and loses its current +167kHz offset.)

Portishead: D3&4 moves from C52 to C62 on 28 September.#

Woodcombe: D3&4 moves from C52 to C62 on 28 September.#

Grampian (STV North)
--------------------

Durris: SDN moves from C52 to C23 on 15 June. Currently restricted to 20kW and 608m (main aerial is 639m). (ArqB out of date - DSO Details has the correct info.)

Scottish (STV Central)
----------------------

Darvel: SDN, ArqA and ArqB transmit from reserve aerial from DSO 2 (25 May) until further notice.

Rosneath VP: From DSO 2 (25 May) to 22 June, ArqA and ArqB subject to a reactive power restriction of 200W 'if required'.

Central
-------

Oxford: SDN, ArqA and ArqB restricted to 12.5kW after switchover until further notice.

Andoversford: BBC A will start up on C62 at DSO 1 next Wednesday and move to C50 at DSO 2.

Knucklas: BBC A will start up on C49 at DSO 1 next Wednesday and move to C39 at DSO 2.

Ross On Wye: BBC A has a note marker but the note is missing. It was due to start on C62- at DSO 1 next Wednesday and is now allocated C50.

Yorkshire
---------

Belmont: ArqA and ArqB now launch on final channels (C53 and C60), restricted to 4kW until 23 November.

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.)

Anglia
------

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.

Tacolneston: Mux 2 moves to C59 on 17 August, before DSO 1!

Meridian
--------

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'.
