(Radio Data System) is a means of
transmitting station call signs or network
identification, a description of the
station's programming, indication of
national, regional or local programmes
and others using hidden space in the FM
signal. Your new receiver is equipped with
RDS to assist in the selection of FM
stations using station and network
names, rather than broadcast
frequencies. Additional RDS functions
include the ability to search for
programme types or to find stations with
a specific programme type with a
stronger signal.
