It is understood that Tim Davie, the BBC director of audio and music, has been approached by commercial radio executives to enlist the BBC in a broader role in DAB. The BBC operates five DAB-only stations alongside its analogue stations on DAB.
BSkyB, Bauer, UTV, UBC Media and The Carphone Warehouse are believed to have held conference calls over the future of the venture. Some of the big radio groups have also now voiced concerns over future digital radio launches.
A UTV spokesman said it was reviewing its options regarding TalkRadio. BSkyB said it was unlikely to find the new partner required to launch Sky News Radio and Bauer's digital radio off-shoot for the women's magazine Closer has been postponed.
