An introduction to RDS
Radio Data System, or RDS as it’s usually
known, is a system used by FM radio stations
to provide listeners with various kinds of
information—the name of the station and the
kind of show they’re broadcasting, for
example. This information shows up as text
on the display, and you can switch between
the kind of information shown. Although you
don’t get RDS information from all FM radio
stations, you do with most.
Probably the best feature of RDS is that you
can search automatically by type of program.
So, if you felt like listening to jazz, you could
search for a station that’s broadcasting a
show with the program type,
Jazz
. There are
around 29 such program types, including
various genres of music, news, sport, talk
shows, financial information, and so on.
The receiver lets you display three different
kinds of RDS information: Radio Text,
Program Service Name, and Program Type.
Radio Text (
RT
) is messages sent by the radio
station. These can be anything the
broadcaster chooses—a talk radio station
might give out it telephone number as RT, for
example.
Program Service Name (
PS
) is the name of
the radio station.
Program Type (
PTY
) indicates the kind of
program currently being broadcast.
