Alterations to be made to the DTT Transmitter Network


<< Back to home.

**NB. Many of these plans are still at the 'drawing board' stage. The inclusion in the list of a particular Transmitting Station is not confirmation that a change will happen. Those plans which are unconfirmed are coloured white in the status column. In addition, just because a particular Transmitting Station does not appear in this table, doesn't rule out any possibility that it won't be re-engineered in the future. This is NOT a definite list.**

25-Sep-02 - The first and second phases of transmitter re-engineering is now complete. 

25-Nov-02 - The Broadcasters have identified transmitting stations that are likely to be included in phase 3 of the re-engineering programme. These stations are highlighted in the list below, and any engineering work is likely to be completed by early 2003
There are currently no plans to make alterations in the ERP or frequency at any other station.

02-Jan-03 - Following the ITC's ruling on the 20th December 2002 (see home page), the operator of Multiplex A - SDN Ltd  will  implement the +3dB power increases within the first half of 2003. The stations that will be increased in power can be identified in the below table as those listed in the "Power Increase" column as "Not mux A" - which indicates that all other multiplexes at that station have already been increased in power. These changes will be made during the engineering work as part of Phase 3

10-Feb-03 - The Broadcasters have now confirmed which stations will be increased in power as part of Phase 3. It expected that the rollout will commence shortly before Easter, although this is still a preliminary timescale.

14-Apr-03 - SDN Ltd has commenced the rollout of +3dB power increases at stations which have already had all other 5 multiplexes increased by +3dB. A full timescale will appear on this page later this week. As of 14th-Apr-03 work at the following stations has been completed : Aberdare, Brierley Hill, Bromsgrove, Plympton.

24-Apr-03 - SDN Ltd - The +3dB power increases have now be applied to the majority of stations. A few stations remain to be completed and they are listed in the table below, together with expected timescale of completion.

01-Oct-03 - The Broadcasters (Digital 3 & 4Ltd and SDN Ltd) are expected to begin their rollout of Phase 3 power increases in late 2003. The work will be completed by early 2004. The BBC and Crown Castle have yet to confirm their plans.

30-Jan-04 - The rollout of +3dB has recommenced following a break over the Christmas and the New Year period.

18-Feb-04- The table below has been updated to indicate where the BBC has also implemented  +3dB increases on its multiplexes. Crown Castle are not carrying out any increases on their multiplexes.
