WHAT IS RDS?
REGIONAL MODE
Some stations are organised in a network.
The Radio Data System (RDS) function on the FM waveband permits:
In different regions, they broadcast different or shared programmes
-
automatic retuning to alternative frequencies carrying the
same station while travelling through different regions (if the
transmitters of this station cover the area through which you are
travelling),
depending on the time of day.
You can follow:
-
-
a regional station only,
-
-
temporary tuning to trafꢀc information announcements,
display of the name of the station, etc ...
the entire network, with the possibility that you will be listening
to a different programme.
Most FM stations use RDS.
These stations transmit non-audible data in addition to their programmes.
TRAFFIC INFORMATION FUNCTION
The data transmitted in this way allows you access to various
functions, mainly displaying of the name of the station, temporary
tuning to trafꢀc information announcements or automatic retuning to
alternative frequencies.
RDS allows you to continue listening to the same station
automatically by means of alternative frequencies. However,
alternative frequencies may not be provided throughout the country.
Radio stations do not cover the whole country, which explains the
loss of reception of the station during a journey.
The Trafꢀc Programme (TP) function permits automatic and
temporary switching to an FM station broadcasting trafꢀc
information.
The radio station or the source that you are listening to at this point
is paused.
Once the trafꢀc information has ended, the system switches back to
the radio station or the source that you were listening to initially.
RDS ALTERNATIVE FREQUENCIES
PROGRAMME TYPES
Your radio automatically checks and selects the best frequency for
the radio station to which it is tuned (if the station broadcasts on
several transmitters or frequencies).
Some stations offer the option of listening to a themed type of
programme as a priority, selected from the list available below:
NEWS, AFFAIRS, INFOS, SPORT, EDUCATE, DRAMA, CULTURE,
SCIENCE, VARIED, POP M, ROCK M, EASY M, LIGHT M,
CLASSICS, OTHER M, WEATHER, FINANCE, CHILDREN,
SOCIAL, RELIGION, PHONE IN, TRAVEL, LEISURE, JAZZ,
COUNTRY, NATION M, OLDIES, FOLK M, DOCUMENT.
The frequency of a radio station covers approximately 30 miles
(50 km). The change from one frequency to another explains the
loss of reception during a journey.
If the station to which you are listening does not have several
frequencies in the region in which you are currently located, you can
deactivate automatic alternative frequencies.
