phil: The owners of the COM muxes decided that it simply was not cost effective to extend coverage beyond the original Freeview sites. To serve all the relays would more than double the cost of provision whilst adding a small percentage of extra viewers, many of whom could receive the signals direct from a main station or via satellite if they require the extra channels.Have you tried receiving the Moel Y Parc transmitter which offers a full freeview service?

Teresa: after switchover in September the signals will be 25 times stronger so yes the engineer is correct in saying that things will improve. You might find that you end up with too much signal and have to remove the amplifier.Although some models of freeview box claim to deal with interference better than others there is really no solution to the situation where the interference is stronger than the required signal.Positioning the aerial so that the house or chimney stack act as a screen to interference from traffic can help, and using good quality fly leads is essential when interference from household appliances or switches is a problem.A mains filter can help with interference within the home. You might decide it is better to wait a few weeks for switchover then see what the situation is like.

Sarah Kerr: If your aerial is set on Huntshaw Cross (rods horizontal) MuxBBCA is on C62-. Check that your receiver is tuning to this frequency rather than weaker alternatives earlier in the scan. Make sure that you do not have a Sky box or games console with the RF output set around C61/C63. Also check that all cables and connectors are in good order.

Mrs V Sowerby: As the problem is only occuring on BBC channels it suggests that the signal on Mux BBCA could be weaker than that on the other muxes. Are you sure that your receiver has tuned to the correct frequency for the transmitter that the aerial is pointing at.If you are receiving Caradon Hill services (aerial pointing slightly E of due South) you should be tuned to C28+. It is possible that a weak signal from Stockland Hill on C26+ has been found instead. If your aerial is set on Huntshaw Cross (roughly NE) the correct frequency is C62-.In that case signals from Caradon or Stockland may have been found earlier in the scan.Do a factory reset to clear the channel list before scanning or manually entering the correct frequencies for your location. If the correct frequencies are stored and the problem still persists it is possible that trees in leaf are partly blocking the signal path and only affecting the BBC mux or you have interference which only affects one frequency from a device such as a 2 way radio.

Paul: You are not currently expected to receive C53 or C57. After the September frequency change and power increase The Wrekin is predicted as giving the best reception for all six muxes at your location.At present Brierly Hill is shown as offering six muxes and Ridge Hill too is another possibility.

James Mooney:If you have lost Sky news, that is MuxC on C52+ and Sky Sports on MuxB (C51) suggests possible interference around C51/C52.Is the BBC4 that you are receiving definitely coming from Sutton Coldfield or have you stored channels from Lark Stoke Mux BBCA? Regarding the aerial when scanning for Sutton channels you need to leave the aerial unplugged for the first third of the scan to miss out Lark Stoke PSBs, then re-insert before C40 to cover the Sutton frequencies. It is very unlikely that you would be able to receive Sky Sports from Lark Stoke as you would need to receive Mux ArqB which is currently low power and not expected to serve your location until September.

James O'Connell: If you are receiving signals from the Waltham transmitter The frequency for Mux2 recently changed to C31 and MuxA changed to C29.This was to avoid co-channel interference problems for viewers in the overlap area with The Wrekin after switchover on that transmitter.To restore reception you need to do a factory reset to clear the channel list and remove all memory of the missing muxes on their former frequencies.Then do a rescan or enter the frequencies manually for the Waltham transmitter.The Digital UK postcode checker predicts good reception for all six muxes at your location.

kevin moseley: The Digital UK postcode checker shows that it might be possible to receive the full Freeview service from Ridge Hill. Reception is shown as variable to poor, but using a carefully aligned group A receiving aerial (an 18 element group A yagi or a Blake DMX 10A or a Triax Unix 52A) might give you acceptable results. Otherwise satellite reception will offer additional free to air channels, though not an identical selection.

pam: Are you able to install a loft aerial? Though not recommended for freeview reception you would usually have better results from a loft aerial than one placed in the room which is prone to signal variation caused by people walking about as well as being closer to interference sources in the home. On the plus side The Digital UK postcode checker shows a strong signal from the Keighley transmitter is expected at your location both now and after switchover. Remember to set any aerial for vertical polarisation (rods vertical) when using this transmitter.

Judith Smart: On 27th April 2011 the SDN mux which carries ITV3 changed frequency at the Wenvoe transmitter.It is now on C42+. At the same time Mux ArqA changed frequency to C45.You need to clear the channel list by doing a factory reset then rescan for channels to restore your service.
