RBDS and RDS
Radio Broadcast Data System (RBDS) is commonly used for FM broadcast in
North America, while the Radio Data System (RDS) is implemented in Europe. In
1998, the two standards were largely unified. Both systems are implemented as
standard features on Technalogix FM transmitters, including the control,
generator, and interface.
RDS uses a subcarrier to embed the FM signal with information. This can be
used to transmit time, station identification, programming information and more.
To control the RBDS/RDS connect to the DB9 on the back of the unit using a
RS232 connection. A USB-to-RS232 or Ethernet-to-RS232 convertor can be
used instead (not included with transmitter).
To interface with the RBDS/RDS you need to install the Magic RDS software.
Magic RDS software is found at
http://www.pira.cz/rds/MagicRDS_Setup.exe .
General operating questions are answered here:

The RBDS/RDS subcarrier level can be adjusted using R108 on the FM Exciter
1.01 circuit board. It should be set between 1.5 and 10% modulation. It is
recommended to turn to 0% if not RBDS/RDS is not being used to provide the
maximum available modulation for the audio signal.
