A receiver can extract digital data from wireless radio frequency signal. The digital data contains at least two sets of compressed digital audio data each associated with a different set of audio program. One set of compressed digital audio data is delivered in a first frequency band and the other set in a second frequency band. One of the sets is stored in a memory system and the remaining set is not stored in the memory system. A user can select one of the sets of compressed digital audio data for decompression and then conversion to analog audio signal.
