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 example, the stations send their station names, and infor-
mation about what type of programme they broadcast, such as
sports or music, etc.
When tuned to an FM station which provide the RDS service,
the RDS will appear, the station frequency (and then the sta-
tion name if sent) is displayed.
The TP (Traffic Programme) will appear on the display when
the received broadcast carries traffic announcements, and the
TA (Traffic Announcement) will appear whilst a traffic announce-
ment is being received.
EON will appear whilst the EON (Enhanced Other Networks
information) data is being broadcast.
The PTYI (Dynamic PTY Indicator) will appear whilst the
Dynamic PTY station is being received.
Note:
When the TP and TA appear at the same time, an an-
nouncement is being made.
When only the TA appears, an announcement is not being made.
