digital radio
**Digital radio** is a broadcasting technology that transmits radio audio using digital signals rather than traditional analog signals, resulting in improved sound quality, more efficient use of the radio spectrum, and the ability to carry additional data such as station information, song titles, and images. Examples include DAB/DAB+, HD Radio, and DRM.
Earlier today my car started displaying colourful icons for DAB BBC stations, but now have reverted to the normal blue box with a radio image in it. Anyone else seen this behaviour?
