RDS (Radio Data System) OPERA
TION
RDS is a broadcasting service which a growing number of FM
stations are now providing. It allows these FM stations to send
additional signals along with their regular programme signals.
For example, the stations send their station names, and infor-
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
TP
(T
raf
fic Programme) will appear on the display when
the r eceived broadcast carries traf
fic announcements, and the
T
A
(T
raf
fic
Announcement) will appear whilst a traf
fic announce-
ment is being received.
EON will appear whilst the EON (Enhanced Other Networks
information) data is being broadcast.
The PTYI (Dynamic PTY Indicator) will appear whilst the
Dynamic PTY station is being received.
Note:
When the
TP
and
T
A
appear at the same time, an an-
nouncement is being made.
When only the
T
A
appears, an announcement is not being made.

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.
