Raaio
Data
System
RDS is a service of the
public
radio institu-
tions which has been introduced
Eurooe-
wide
to
facilitate
the search for
the desired
VHF radio
station and its interference-free
receDtion.
In
addition to the
programs
transmitted,
RDS
transmitters also radiate
a digital data
telegram
containing information which
is
automatically interpreted
by RDS receivers.
lf RDS is
switched on, the
designation of
the radio
station is shown on the
display.
Each RDS station transmits
at several fre-
quencies.
The radio receiver
continually
compares the signal
quality
of these fre-
quencies
during iravel and changes fre-
quencies
to maintain
reception of the
stron-
gest
frequency
at all
times
(best
reception
of the selected radio
station). The radio
station designation
on
the
display remains
unchanged.
