stations are now providing. It allows these FM stations to send
additional signals along with their regular programme signals.

mation about what type of programme they broadcast, such as
sports or music, etc.
When tuned to an FM station which provide the RDS service,
the RDS will appear
, the station frequency (and then the sta-
tion name if sent) is displayed.

the received broadcast carries traf
fic announcements, and the
T
A
 (T
raf
fic 
Announcement) will appear whilst a traf
fic announce-
ment is being received.

information) data is being broadcast.
The PTYI (Dynamic PTY Indicator) will appear whilst the
Dynamic PTY station is being received.
Note:
When the 
TP

T
A
 appear at the same time, an an-
nouncement is being made.

NOTES ON SCHEMATIC DIAGRAM
 Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.
 Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolytic capacitor, the expression “capacitance/withstand
voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
