The final stage of the digital TV switchover in much of Pembrokeshire is being completed today (Wednesday).

All terrestrial TV signals were turned off at the Preseli transmitter shortly after midnight.

The analogue services will remain switched off permanently allowing new freeview channels to be broadcast from 26 local relay transmitters including, for the first time, in areas such as St Davids.

The transition was due to be completed by around mid afternoon today with Freeview, BT Vision and Top Up TV equipment needing to be retuned in order to receive all the channels available. Broadcasters are planning changes to the freeview service over the autumn, so householders are reminded to continue to retune whenever their channel line-up changes in order to keep their equipment up to date.

The switchover has made it possible to extend the level of freeview coverage to reach 98% of homes in the country.

Viewers receiving their signal from relay transmitters will see the number of TV channels available free via an aerial increase from four to around 20.

Digital TVs or analogue sets converted with a digital box will be able to receive BBC One, BBC Two, ITV1, S4C and Five, plus additional digital channels such as BBC Three, BBC Four, BBC News, ITV2, ITV3, More 4 as well as digital text and radio services.

Emyr Byron Hughes, Digital UK's National Manager for Wales, said: "People in South West Wales have responded really well in adapting to the change and preparing in good time."

Anyone still struggling to get digital can contact Digital UK, the independent body leading the switchover, for advice and support via its website or helpline 08456 505050.
