will shimmon: If your aerial is mounted for vertical polarisation and pointing at Aldeburgh no amount of boosting is likely to enable reception of extra channels. Looking at your reception predictions the most likely transmitter to provide signals on the COM muxes at the present time is Tacolneston. Reception is shown as variable however, so careful positioning of the aerial may be required to receive the required signals. Direction for Tacolneston is NW, set for horizontal polarisation. After 27th June 2012 you might find Sudbury provides a more reliable alternative, otherwise I would suggest receiving the PSB muxes from Aldeburgh and the COM muxes from Tacolneston, with the 2 aerials linked via a diplexer in order to achieve reliable reception on the PSB muxes as Tacolneston shows a deterioration in reception over time, especially on C50 which is to be used by Mux BBCB from a date yet to be announced in 2013. Mux ArqB will use C39+ from when the change takes place and shows a slight improvement in predicted reception as a result.

Chris Wildey: This sounds like the council is no longer prepared to pay for the communal aerial to be maintained, the contract to provide and maintain the aerial has possibly expired. Whilst there is no such thing as a digital aerial there are certain adjustments that may be required to accommodate changes in frequencies and transmitter power following DSO. Some councils made a decision to replace existing communal aerials with an all singing and dancing version which also provides DAB radio and satellite services for Sky and sometimes foreign channels, this came however at a price which many tenants complained about, especially if they had no TV, only watched terrestrial channels or were cable subscribers! That is why other councils decided to let tenants choose (and pay for) their own method of viewing TV.

ian: Try deleting all the channels in the channel list by doing a factory reset or "delete all channels". Then manually tune to the frequencies of all the muxes for your desired transmitter. At present you possibly have BBC2 from a different transmitter to that supplying BBC1.

John Ledbury: You are correct that retuning can disrupt your viewing in locations such as yours where there are signals from three or four transmitters present, retuning tends to find and store the channels from the first signal found during the scan, even when that signal is too weak to give reliable reception. The stronger signals which are to be found later in the scan are then ignored as duplicates. If your aerial is pointing to Belmont you should have Sky News etc from Mux ArqA on C53 and Film4, ITV4 etc from Mux ArqB on C60-. Manual tuning of the Mux frequencies is the best way of storing the correct set of channels. After clearing the channel list by doing a factory reset, tune C22, C25, C30, C53 and C60, also C28 0n HD tuners. Note that you need a wideband aerial to receive the higher frequencies from Belmont, aerials installed a while ago are likely to be Group "A" (identified by a red stopper at the end of the boom) and are only designed to work on frequencies below C38.

ian: Yes, for Kimberley tune C27, C24, C51, C52, C48 and for HD (if required) C21+

D ESSERY: Check that BBC1 & BBC2 are tuned to the correct frequency for the transmitter that your aerial is pointing to. If your aerial is pointing NNW To Hemel Hempstead and set with the rods vertical the correct frequency is C56. If you have found weak signals from Crystal Palace or Sandy Heath in the early part of the channel scan, or if your receiver is still tuned to the former Mux 1 frequency C48 it would explain the "No signal" messages being displayed. You will need to clear the channel list by doing a factory reset, then either manually insert the correct frequencies (C56, C55, C68, C59-, C62, C65) or commence the scan with the aerial unplugged, wait until the scan reaches about C53 then plug the aerial back in.

Barry: Looking at the Digital UK postcode checker predictions you could receive a signal from Steyning after DSO if using a suitable aerial (it is currently analogue only). However there would not really be any point, as not only is the predicted reception at your location not as good as that from Midhurst, it is also only planned to transmit the three PSB muxes (Freeview Light).Notice Heathfield is also predicted to give good reception on all six muxes after DSO in June 2012.

Barry: Digital UK do not currently predict any Freeview reception for you from Midhurst, at best you are only expected to receive poor/variable signals from Heathfield. This situation continues until, as you said, DSO at Midhurst at the end of February 2012. You should then receive all six muxes from Midhurst, with good reception predicted for your postcode area.

Hayden: The target service areas for the Derby relay are the suburbs of Allestree and Chaddesden where an aerial pointing at Sutton Coldfield also points (roughly) to the mast in Littleover from which the relay transmits. If you wish to receive East Midlands news you need an aerial directed to the Waltham transmitter. The Digital UK postcode checker shows good reception should be possible on all six muxes from Waltham.

Pete Stears: The Digital UK postcode checker predicts good reception to be available on all six muxes from Crystal Palace after switchover on 18th April 2012. Prediction is for good reception 99% of the time in 91% of locations in your postcode area (or better, depending on mux). The power of Crystal Palace increases tenfold to 200kW on each mux. Although the Hemel Hempstead full service transmitter also has a power increase the frequencies allocated will also be in use at Hannington and Oxford, resulting in a prediction of variable or poor reception at your location.
