Sarah: If the TVs have no scart socket you will have to search out a freeview box with an inbuilt RF modulator so that the output can be received via the aerial socket. Remember that the transmitter power is increased at switchover, so you might find that you are then able to receive all the channels downstairs using your amplified indoor aerial. Reception upstairs is usually better than downstairs and you are shown as being in a good reception area (albeit that predicted reception is based on using a roof aerial, with no local obstructions in the signal path) You could try a suitable freeview box on one of the TVs, then you will be in a better position to decide what you need to do.

Cain: When the power increases at Stockland Hill on 18th April 2012 it is possible that you might be able to receive the COM muxes direct from Stockland Hill using a good quality group "A" aerial mounted for horizontal polarisation. There are no plans by the mux owners to install additional equipment to add these muxes to the Exeter St Thomas relay due to the extra cost involved. With regard to the regions shown by ITV1 HD (and ITV1+1), this again is down to equipment costs, but no doubt in due course each region will eventually be converted to HD and also have the correct version of ITV1+1.

Richard Dover: The BBC report that the Ardentinny transmitter is off air since 08:06 on 3rd January 2012. There is no information regarding an expected return to service, this will no doubt be as soon as engineers are able to rectify the problem in the extreme weather conditions.

Concrete: Freeview on Mux BBCA (all the standard definition BBC channels) starts on 10th October 2012 on C45 from Strabane.....Two weeks later on 24th October 2012 Mux D3+4 starts on C42 with UTV, ITV2, C4, C5, C4+1, E4, more$ and UTV+1. Mux BBCB (HD channels) starts on C39+. All transmitters in the Ulster TV region switchover on these dates.

Jeff Meagor: Digital UK do not make any prediction for reception from Plympton in your postcode area. There is in fact a frequency clash with Beacon Hill and Plympton both using C42 and C45. Which channels are you losing from Beacon Hill in the latter part of the day? If it is those carried on the SDN and ArqA muxes then it is possible that interference from Plympton is the cause. Careful aerial positioning to find the best signal from Beacon Hill whilst losing any interference from other directions could give you more reliable reception of the temperamental channels. You are incidentally predicted to have good reception from Beacon Hill on the five Standard definition muxes, the HD mux is shown as variable. You could see a more accurate prediction for yourself if you click on the link to Digital UK tradeview, then change the address to include your house number. Predictions shown in green are for good reception, subject to there being no local obstructions such as trees or tall buildings in the signal path.

mike Roberts: Are you sure it was the Emley Moor signal being received in Manchester? There is also a Capital FM in Manchester.

Roger Evans: The BBC national multiplex carries the same content from all transmitters- it has to, as the national mux is transmitted as a single frequency network. Radio Wales is allocated space on local/regional commercial multiplexes in Wales in those areas that the service is available.

Ann: If you had problem free reception prior to switchover there are usually two possible reasons for the same installation suddenly giving trouble when the transmitter powers are increased. Firstly, when scanning for channels, the tuner finds signals from a different transmitter to that to which the aerial is pointing, it then stores channels for weak or erratic signals. When the correct signals are found the extra channels are either stored in the 800s of the channel list or ignored completely as duplicates. If this is found to be the case manual tuning of the correct set of frequencies, after first clearing the channel list, usually restores correct working. The second problem is the use of very high gain aerials or amplifiers which might have been needed in order to receive the low power signals before switchover. When the high power working began the signals were then too strong, producing similar effects to weak signals. in this case amplifiers need to be removed or gain turned down, or an attenuator fitted in the aerial feed to restore correct reception.

Sarah: How do the TVs receive the analogue channels at present? You will have to purchase a freeview box for each TV if you wish to continue viewing broadcast channels, but if you are in a strong signal area and currently have a good clear analogue picture it is possible that your freeview boxes will work ok using whatever aerial you currently have. However, if you are putting up with a grainy picture which changes as people walk about, then you will need a better aerial, at least in the loft in order to deliver a stable signal to each TV.
