JohnB: The BBC national multiplex is transmitted from a mast in Parkstone at 2kW. This explains the good reception that you enjoy on BBC stations.

Conor: ITV1 Granada HD is available free-to-air on satellite, if you don't mind a Manchester slant to the commercials.

andy: This is usually because the channels are being received from two different transmitters, the corresponding BBC1 (and possibly BBC2) to the errant BBC3 could be stored in the 800's of the channel list. Did you do a factory reset to clear the channel list of all data before scanning for channels? I am wondering if BBC3 was off air when you rescanned, so the box did not treat it like the other channels that were broadcasting at the time, leaving the old reference from Belmont in place.

JohnB: Future additions to the Digital One network are only likely to be in areas where there is presently a good signal on analogue Classic FM, but poor or no reception on DAB. D1 already consider that some of the 133 transmitters they have in service are uneconomic, and Ofcom is only requiring coverage to be provided at a level that is reasonable with due consideration to the commercial interests of the network. This differs from the improvements planned for coverage to the local muxes and the BBC national network. Bournemouth 11B could be added to the Parkstone mast in addition to the existing transmitters at Nine Barrow and St.Catherine's Hill.

tony: Are you sure that you are out of range for reception of the full Freeview service from Crystal Palace? You would, of course require the correct aerial to receive it reliably, just as you did in the analogue days if you wanted Channel Five from Croydon. To be fair, you do expect to receive more channels with a subscription to Sky or V.M., but it is a fair point that advertisements for Freeview and DAB radio do need to make it clearer that provision of all services is not universal. Similarly it needs better information on "HD ready" equipment with regards to inability to receive Freeview HD (or Saorview in Ireland). Your idea for a one off contribution to cover the cost of installing the extra muxes on relay transmitters is interesting, but at this stage when Ofcom is looking at selling as much spectrum as possible for 4G, would be unlikely to be considered due to frequency shortage even if funding was available.

Bob Munday: The prediction for reception from Hastings is not that good at your location, due to possible interference from Eastbourne and Rowridge which will be using the same frequencies as Hastings post DSO. If this does turn out to be a problem, as you are predicted to have good reception on all six muxes from Heathfield after switchover it might be a good idea to set your aerial for reception from Heathfield after 13th June 2012.

Nick: Originally all transmitters offered an analogue service, usually on four or five channels. Each transmitter therefore had its own page dedicated to the analogue switch-off. Additionally there were 80 transmitters which offered a (usually) low power Freeview service. These transmitters had the "Freeview on the Sudbury TV transmitter" type pages to give details from the viewpoint of a digital household. Following DSO the analogue orientated pages are re-titled "digital TV transmitter" with details given for the replacement digital services, the Freeview orientated pages being similarly up-dated to show the current situation.

lee: The BBC status report for the West Runton Relay transmitter is "off air" since 17.03 for Mux BBCA and 17.25 for Mux HD.

charlotte harvey: To receive the commercial muxes you need to be able to receive signals from the Redruth transmitter, which is roughly SSE from Portreath. It really depends how much of an obstruction is presented in the signal path by the local hills. Trying a postcode for Bassetts Acre Holiday Apartments, for example, gives a prediction of good reception on all muxes from Redruth for that location.

Andy: Is HD likely to become the norm? What about standard definition, DVB-T2? This allows for the greatest number of channels to be fitted into each mux, which is what the mux owners are interested in. HD is likely to be a subscription based service for those who particularly want it. The German TV channels seem to be going down that road too. A few years ago it was thought that stereo radio was the future. It is now not unusual to see radio stations opting for mono transmission on DAB in order to fit in more stations, and reduce transmission costs.
