Program service name (PS)
This information tells the receiver what station it is receiving. The information will be shown on the radio display, e.g.
BAYERN 3.
Alternative frequency (AF)
A list of alternative frequencies that transmit the same programme is transmitted. If the signal of the current station
becomes too weak, the receiver uses the AF signal to determine where to look for a station with a stronger signal.
Programme type (PTY)
This code provides information about the type of the transmitted programme (e.g. sports, classical music, news etc.).
Thus, the listener can look for the programme of choice more specifically.
National disaster alarm can also be announced this way. However, not all radio stations offer PTY service.
Enhanced other networks (EON)
Many chains of radio stations 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 news station when traffic
announcements are made, even if a different programme of this chain is on.
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 announcement) for the time of a traffic announcement.
Clock time (CT)
Many stations transmit the current time in the RDS data. When the device reads that signal, it sets the built-in clock
automatically.
The advantage the RDS system offers is that when you leave the transmission area, the device will automatically
switch to a station with a stronger signal. However, it only switches if it detects a station with a stronger signal and
the same programme.
The RDS system cannot respond to temporary signal drops as this would cause the radio to switch back and forth
continuously. The listener would feel much more disturbed by this than by temporary reception difficulties.
Another advantage of the RDS system is that the station name is displayed. The station name of an RDS station is
shown on the display of the car radio.
