Briantist: Downtown Radio does effectively broadcast to the whole of Northern Ireland on DAB - which is good news for listeners who live miles away from Belfast.

nick: The Sudbury COM muxes share frequencies with Waltham (C56 & C58) and Belmont (C60). Similarly Dover shares frequencies with Tacolneston (C50, C55, C59) and Sandy Heath (C48 & C51). It is very likely that these transmitters are responsible on many occasions for the interuptions to your normal reception.

Robert Keedwell: Where does your aerial point? Hutton is vertically polarised. If you want to receive the COM muxes these are only available from Wenvoe which uses horizontal polarisation.

mark winters : According to an article in the North Devon Gazette, Arqiva have repaired a fault on the Westward Ho! transmitter, so all should now be well.

julie jacobs: If you supply your postcode, or one for a nearby shop or public building it will be possible to see from the DUK reception predictor what channels you might expect to receive. The Brixham relay only transmits the PSB muxes, so would give you BBC channels and ITV, C4, C5, ITV2 etc only as listed above,.plus the HD channels. However if you are able to receive signals from Beacon Hill or Stockland Hill (when using a suitable aerial) you might be able to receive the full Freeview service.

julie jacobs: You appear to be in the area that the Brixham relay is intended to serve, with excellent reception predicted, but only on the PSB muxes. Your aerial would point NNE with the rods vertical for this transmitter. Using an aerial on Beacon Hill ( pointing NW and set for horizontal polarisation) the prediction is for a fair chance of good reception on the PSB muxes, but the COM muxes are decidedly iffy, with no prediction offered for SDN, and poor reception predicted for ArqA and ArqB, possibly due to likely interference from other transmitters using the same frequencies.

PJH: Better sound quality on a portable radio on FM? Maybe if you live in a strong signal area. FM reception on the average portable radio using a telescopic rod aerial in many areas is frequently marred by hiss and buzzing or whining in the background from any computer in use within a hundred yards of the receiver!

Donna: Is this using a communal aerial, or is it your and your neighbours' own individual aerials? It is quite possible if you are on reasonably high ground that you are receiving signals from Caradon Hill. This transmitter reaches many parts of North Devon, as such it was the only source of BBC2 in the days before Huntshaw Cross came on air! Do a manual tune on C21 for SDN from Caradon Hill.

George Buchanan: All the masts which transmit BBC FM services to the Western Highlands are planned to have DAB transmitters installed in the near future. Additional sites at Penifiler and Duncraig are also on the future DAB transmitter list.

michael : The problem really is that DAB coverage has to be better than that on FM if it is to be an acceptable replacement. It is quite normal, at least in the Derby/Derbyshire area for FM to have varying amounts of hiss, dropping into mono at times when driving or walking about. Such a variation in signal on DAB is likely to result in "no signal" evey hundred yards in some areas.It took quite a long time before BBC local radio on FM increased power from a few watts to several kilowatts to achieve acceptable coverage. It remains to be seen if DAB power is to be stepped up in record time to service mobile listening!
