Pirate FM has learnt hundreds of Cornish families could lose their TV signal.

The government is admitting new 4G phone signals may interefere with our favourite shows. Fixing it with a filter could cost a hundred pounds. Some homes could have to switch to satellite.

The problem is expected to be particularly bad for people living near mobile transmitters. Estimates say it could hit 32,000 homes in the southwest.

The new 4G network is supposed to provide mobile handsets with broadband speeds. The system is currently being trialled in parts of the Duchy.

Jill Sadler from St Newlyn East is among those taking part in the testing. She said, "I'd be very frustrated, especially in this day and age you expect things to be perfect. To pay extra money to get a clear signal, I wouldn't be very happy at all. Why should we pay for something that's been forced upon us?"

Ed Vaizey, Minister of Culture, insists there will be support for Cornish families who are affected:

"We've come up with what we think is a very generous figure, that should cover all households. We can't offer cast iron guarantees. What I would say is that we will not allow anyone whose television signal is interfered with by 4G, to be left in the lurch.

"In 2013, we're going to start introducing 4G mobile services. Now this is something that a lot of people want, particularly in Cornwall which is one of most wired up parts of the country. It's got a fantastic superfast broadband network being put in place at the moment. That's going to make our smart phones work faster and so on."
