The legislation includes six specific provisions designed to facilitate a transition to DAB-only for the BBC as well as larger commercial channels, while improving the lot of smaller regional and community stations, expected to remain on analog FM indefinitely.
The device utilizes a compact HD Radio module as well as Radio Shack's Gigaware iPod accessory.
