RDS (Radio Data System) OPERATION
RDS is a broadcasting service which a growing
number of FM stations are now providing. It allows
these FM stations to send additional signals along
with their regular programme signals. For exam-
ple, the stations send their station names, and in-
formation about what type of programme they
broadcast, such as sports or music, etc.
When tuned to an FM station providing the RDS
service, RDS will appear, the station frequency (and
then the station name if sent) will be displayed.
The TP (Traffic Programme) will appear on the dis-
play when the received broadcast carries traffic an-
nouncements, and the TA (Traffic Announcement)
will appear whilst a traffic announcement is being
received.
EON will appear whilst the EON (Enhanced Other
Networks information) data is being broadcast.
Note:
When the TP and TA appear at the same time, an
announcement is being made.
When only the TA appears, an announcement is
not being made.
