A radio station which first made waves across the region in the 1960s is back on the air after 25 years.

Radio Caroline, the former pirate station which began broadcasting in 1964, has been announced as the latest addition to the digital radio stations available to the greater Norwich area.

Radio Caroline was initially broadcast from a former passenger ferry, the MV Caroline, which was anchored in international waters off Felixstowe.

The station has taken on a number of different forms over the years, and since 2002, it has been broadcasting online and through satellite services. However, this will be the first time that it has been on the air in the region since 1990.

It joins a number of radio stations that have newfound digital coverage, including Future Radio, Jazz FM and Radio Norwich, as part of a trial service on offer from Norwich-based not-for-profit broadcasting company Future Digital Norfolk Limited (FDN).

The trial service, which was launched in September, will see a number of digital radio stations broadcast across the region, and is initially set to last until June.

Lawrie Hallett, technical director of FDN, who broadcast on Radio Caroline in the 1980s, said: 'We've had a great deal of interest in our digital audio broadcasting (DAB) transmissions for Norwich since they launched in September.

'We chose Radio Caroline as the latest addition to the airwaves, not just because of its local history, but also because its rock-based music format adds something extra to the choice of available stations in the greater Norwich area.'

Radio Caroline is broadcasting on DAB now.
