Radio Data System (RDS)
The Radio Data System allows radio broadcasting sta-
tions to send data signals on a subcarrier frequency
which is added to the stereo signal. RDS was developed
to give FM receivers user-friendly features, such as
Program Service name (PS) and Program Type (PTY).
Program Service name is typically used by the broad-
caster to display the station’s name or call letters, for
example ЉWNICЉ. Typically these are 8 characters in
length and are displayed by the radio for those stations
which are broadcasting this information. PTY (Program
Type) is used to characterize the station’s program ma-
terial, for example ЉRock MusicЉ.
PTY (Program Type) Button
Pressing this button once will turn on the PTY mode for
5 seconds. If no action is taken during the 5 second time
out the PTY icon will turn off. Pressing the PTY button
within 5 seconds will allow the program format type to
be selected. Many radio stations do not currently broad-
cast PTY information.
