The station, which joined Digital One for an initial six-month period, will now broadcast on DAB permanently with a new schedule featuring additional presenters at evenings and weekends. The presenters have yet to be announced.
Amazing Radio is also launching new online stations streaming genre-specific music through AmazingTunes.com. The first such station is Amazing Ambient.
To celebrate the changes, the station is offering all ad opportunities on the station free to charities until twelfth night (6 January).
Amazing Radio plays tracks from AmazingTunes.com, which allows unsigned artists to sell their music direct to consumers.
Separately, Christian media organisation United Christian Broadcasters and Panjabi and English station Panjab Radio joined Digital One today (1 December).
A spokesman from United Christian Broadcasters said it aimed to provide resources to churches, Christians and people seeking a better understanding of Christianity. Its output was previously available in major cities in England, Wales and Northern Ireland on DAB and on Sky, Virgin Media and the internet at UCBmedia.co.uk.
Panjab Radio will broadcast music, news and speech in Panjabi and English. It was previously available on Sky and on DAB in London, West Yorkshire and the West Midlands.
