Peter: Aerials installed for reception of the Sheffield/Crosspool transmitter were originally "group A" type, which were (then) designed to receive the frequencies between C21 and C34. When Channel Five began transmitting on C67 it became necessary to install a wideband aerial which receives all frequencies between C21 and C68. If your aerial is reasonably new it is most likely a wideband type.After switchover you will initially have signals between C21+ and C63. After 27th September 2011 all signals will be between C21+ and C45. Whilst a wideband aerial will still be suitable after that date it might be better to fit "group K" aerials on new installations to limit the reception of future 4G mobile phone signals.

Graham Powell: Depending on whereabout you are located in DY13 it is possible that the C34 signal from Bromsgrove is strong enough to block the HD signal from Lichfield. Some parts of Stourport have a choice of several transmitters which offer good reception of the HD mux, including Ridge Hill, The Wrekin and Bromsgrove which are already in service.

tom Mckeown: What is your postcode? The Digital UK postcode checker gives details of predicted reception from all available transmitters for most postcodes in the UK.

tony: Until 21st September MuxD from Sutton Coldfield uses C55 which places the line up of frequencies in use at S/C for standard definition muxes in group E. (The HD mux from Lichfield on C34, if required, changes the required aerial group to wideband.) From DSO step 2 on 21st September 2011 all muxes from Sutton Coldfield will use frequencies in group B, which is also the original group used for the analogue signals.

Andy Beard: Services from Sudbury are expected to be on the air by 6am on 6th July 2011 and 20th July 2011. Retunes are required on both these dates to continue viewing Freeview services. Note that relay switchover times are expected later in the day, mostly mid-morning, except for Wivenhoe Park and Woodbridge which are expected mid-afternoon.

Kim Lay: Today (6th July 2011) saw DSO stage 1 implemented. This involved switching off analogue BBC2 and replacing it with Mux BBCA at high power, that is all the BBC standard definition TV and radio channels. On 20th July 2011 DSO stage 2 will see the remaining analogue services switched off and replaced by Mux D3+4 (includes Channel Five) and Mux BBCB (the HD channels) switched on at high power. The COM muxes, which are regarded as an add-on service do not switch on their high power transmitters until 27th June 2012, when the frequencies become available.

Jim Hughes: Are you sure that you have channels from Waltham on C49 stored in the "normal" positions for BBC1 etc. It is possible that you are receiving BBC1 from Sandy Heath on C27 in addition to the Waltham option, in which case BBC1 East Midlands could be stored in the 800s of the channel list. The Digital UK postcode checker shows Belmont, Sandy Heath and Waltham all give good reception of BBC channels at your location. As Sandy Heath is almost directly opposite Waltham from your location this is the most likely additional option to be found.

Liam: There is an improvement to the reception of Mux ArqB shown on 16th November 2011, when the frequency changes temporarily to C63, but still at low power. As you are are using an indoor aerial it might not be possible to achieve reliable reception of this mux until 27th June 2012 when frequencies become available enabling the COM muxes to switch to high power transmitters.

Rob: There should be no change to the signal on C68 until it is switched off on 20th July 2011 and replaced by Mux D3+4 on C41. A number of posts have mentioned that it is no longer being found, possibly because the signal is so weak compared to the very strong signal on C44 it is being overlooked. If you are able to do a manual tune try entering C68 first before adding the other muxes, that is after first clearing the channel list by doing a factory reset.

Dee: Basically the yellow areas are those within coverage where that particular transmitter is expected to provide the strongest signal, the green areas are those where an alternative transmitter might give a stronger signal.For accurate (predicted) information regarding reception at a particular location enter the postcode into the Digital UK postcode checker and tick the trade box or click on the link for "Digital UK tradeview" when available. Your postcode is served by the Haltwhistle relay, a Freeview Lite transmitter giving the PSB muxes only.
