BBC Radio Shropshire on RDS radios
Tuesday 2 December 2008: We are making some changes to Radio Shropshire transmitters that affect the information that is sent to RDS radios (as found in most cars). If you have Radio Shropshire stored on a preset button on your RDS radio, on or after 2 December you need to manually tune to the station again by finding the right frequency and then re-save it as a preset. The station frequencies are not changing. For more information, please see the BBC Shropshire website.

Isle of Man - transmitter engineering work
Saturday 29 November 2008: The new aerial for the digital TV services at the transmitter at Carnane, outside Douglas, needs to be tested before it can be used after digital switchover. The tests are due to take up to four hours and will take place during the day on Saturday 29 November. During the test, all television services - BBC, ITV and Channel 4 - will need to be closed down.

This will affect viewers in most of the Isle of Man - wherever the TV signal comes from Carnane or other transmitters that take their feed from Carnane. However, it will not affect viewers in the north-east of the island whose signal comes from the transmitter at Kimmeragh, or those who receive signals from the mainland. It will not affect viewers watching satellite TV.

Information about this planned work will be given on Manx Radio and on North West Tonight on the local news.

The BBC apologises for the disruption to services caused by this essential work. For more information about the switch to digital in your area, please see the Digital UK website or phone Digital UK on 08456 50 50 50.

Problems with some Freeview digital set-top boxes: box no longer working - channels missing - channels moved to the 800s
Recent changes to some transmitters could mean that a small number of Freeview digital set-top boxes, particularly older ones, no longer work. In other cases, some channels may have gone missing or appear to have moved to channel numbers in the 800s in the electronic programme guide (EPG).

Most homes will be unaffected by the transmitter changes, but if you are having problems, first try rescanning your set-top box.

If BBC and ITV channels are missing from their normal channel numbers and have moved to the 800s in the EPG - if, for example, BBC One is on channel 801 - this may be solved by an over air download (OAD). For more details and instructions on how to receive the download, please go to the Freeview FAQ page.

After taking these steps, if you are still having problems, please contact the manufacturer or your local retailer for more information. Please note that some box manufacturers are no longer in business.

The changes to the transmitters are being made by DMOL, the company that manages the digital terrestrial television multiplexes. The changes are necessary because there are now more channels and interactivity than when Freeview was originally launched. Some Freeview boxes will no longer be able to function as a result of these network changes. For more details, please visit the Freeview help page.

Why am I currently having problems with some BBC services on satellite?
12 August 2008: We have been made aware that a small number of viewers are experiencing problems receiving BBC News and some red button content on digital satellite. Having made thorough checks, we are confident that there is no fault with the transmission, but that the problem lies with individual satellite-receiving installations. Viewers are advised to contact a reputable satellite or aerial installer for further assistance.

I've recently rescanned my set-top box and I've lost some of my channels - can you help?
We suggest you contact your manufacturer for further advice if, after performing a rescan, you have any problems obtaining channels that have moved to another multiplex.

I already have a non-Sky satellite receiver. Can I receive the new Freesat channels?
The BBC and ITV launched Freesat, a new free-to-view satellite service, on 6 May 2008. If you have a non-Sky satellite receiver, the channels are the same as those you can already receive. However, for the full range of on-screen programme information and interactivity you will need a Freesat set-top box. And to view BBC high-definition (HD) transmissions, you will need a compatible satellite HD receiver. For more information about the service, please go to Freesat.

Why can I no longer receive some BBC radio stations via satellite?
Some BBC radio stations on satellite have moved their location. If you have a Sky satellite receiver you need do nothing, but if you have a 'free to air' type receiver you will have to make the changes manually, otherwise you will eventually lose the stations. You can find details on this page - channels with changes are marked.

Why do I have London news on BBC One instead of my local region?
Local news and regional programming is a complex business and sometimes doesn't go entirely to plan. If there is a problem and a local news bulletin is missed or dropped, BBC One defaults to the London region programming, and this is why you may occasionally see London news instead or your own region.

If you watch the Breakfast programme, BBC One and BBC News show the same programme, but for technical reasons only BBC One can provide regional news bulletins. At these times, BBC News shows London news.

Why does my DAB radio clock not show the correct time?
We are aware that some DAB radios can display a clock time up to one minute adrift from the correct time.

The time shown on the radio's display screen is set from the broadcast signal, and is regularly checked and, if necessary, adjusted to match the signal. This can only happen when the radio is switched on and receiving a station. Many radios only check the broadcast time once an hour.

There are several reasons why the radio's display screen does not show the correct time:
