TELEVISION viewers who use freeview or analogue will have to retune their sets today.

Digital UK are carrying out a "reorganisation of the airwaves" in preparation for the digital switchover in 2012.

It means that if you receive your television channels through an aerial rather than cable or satellite, your signal will change from today.

To carrying on recieving all the available Freeview, Top Up TV or BT Vision services, viewers in Hampshire, east Dorset, West Sussex and on the Isle of Wight - who all recieve their signal from the Rowbridge transmitter on the Isle of Wight - will need to re-tune.

The analogue Channel Five TV signal from the Fawley transmitter is being switched off - meaning viewers in Southampton, Gosport and Portsmouth and parts of the Isle of Wight will need digital TV in order to watch Five.

Freeview viewers can retune by pressing menu, then install, then auto-setup, says Digital UK.
