Operation
Program Service (PS)
This information tells the receiver which station it is receiving. It is directly displayed in the display of the car radio,
e.g. BAYERN 3.
Alternative Frequencies (AF)
A list of alternative frequencies that send the same programme is transmitted. If the transmitter station currently
received becomes too weak, the receiver detects from the AF signal on which frequencies it must search for a better
transmitter.
Program Type (PTY)
This code gives the receiver information on the type of the transmitted programme (e.g. sports, classic, news etc.).
The listener can select his favourite programme more directly.
A national disaster alarm can also be sent this way. However, not all the radio stations offer the PTY service.
EON Information
Many radio station chains with various programmes only have one programme with traffic information. If EON
information is transmitted, a radio equipped with an EON function switches to the Traffic Announcement station
whenever such announcements are made, even if a different programme of this chain is being played.
If you listen to Bayern 4 for example (no traffic announcement) and the TA button is activated, the radio will switch
to Bayern 3 (with traffic announcements) for the time of a traffic announcement.
Clock time (CT)
Many stations transmit the current time in the RDS data. If a radio receives this signal, it sets the in-built clock
automatically.
Therefore, when you leave the transmission area, the RDS system has the advantage that it switches to a similar
transmitter station that can be better received. However, it only changes when it finds a better transmitter station with
the same programme.
Short signal attenuations due to the reception cannot be eliminated by the RDS system either, since this would mean
that the car radios permanently switches back and forth. The listener would feel much more disturbed by this than
by short-term reception problems.
Another advantage of the RDS system is that the station name is displayed. The station name of an RDS station is
displayed in the car radio.
