Frequency Question (FAQ)

  1. 1.      What is Radio broadcast data systemRDS

Radio Data System (RDS) is a standard for helping people insert some data information in a  FM radio broadcasts station.

RDS transmitted including timestation identification and program information.

The standard began as a project of the European Broadcasting Union (EBU).

  1. 2.      Why you need to build fm radio station with rds?

RDS provides a digital channel for ordinary FM radio stations, allowing the radio to provide users with more features, including the following illustrations:

Fmuser-Rds-A-Encoder-Radio-Station-Transmitter (4)

For more information on RDS features, here’s an introduction to Wikipedia:

https://en.wikipedia.org/wiki/Radio_Data_System

The most important features is AF, TA, TP, it help FM radio station do more…

a)     RDS Traffic Announcement (TA) :

RDS-AEncoder1 (6) RDS-AEncoder1 (5)

The severing of the increased busy traffic, it is now interested in various countries in Africa to insert RDS signals when constructing a transmitting station, so as to realize the most economical broadcast of some traffic information by means of coverage of FM signals.

b)     Traffic Program (TP):

With the TA and TP functions of RDS, RDS helps radio in-vehicle users to obtain traffic information faster, reduce congestion in the city, and increase the listening rate of the radio station.

c)     Alternative Frequency(AF):

RDS AF help drivers automatic frequency switching between the Relay stations.

Inserting the RDS signal in the transmitter can also automatically switch between multiple different frequency broadcasts in the same program. The receiver automatically switches the substitute frequency AF by detecting the PI code in the RDS signal to ensure that multiple relay stations are passed. Broadcast stations that achieve nationwide coverage achieve seamless coverage and seamless listening. When the car passes the signal superposition zone between the two frequencies, the AF function of the RDS will automatically switch to the same program at different frequencies.

  1. 3.      How is the RDS Alternative Frequency (AF) work?

Here is a video about ow the RDS AF replacement frequency works on youtube.

  1. 4.      What is needed to build an RDS broadcast?

A: A RDS Fm radio transmitter equipment kit list:

1)      FMUSER RDS-A encoder

2)      FMUSER FSN-1000W Fm transmitter with 57khz

3)      RDS encoding software

4)      Cable and antenna

  1. 5.      How can I build my rds channel on my Existing transmitter system?

 Fmuser-Rds-A-Encoder-Radio-Station-Transmitter (7)

1)      Confirm whether the current transmitter already has a 57khz input interface.

2)      Purchase FMUSER’s RDS-A encoder to insert your digital signal into your radio broadcast.

3)      Run the Rds software on your computer and insert your radio station logo, traffic information…

4)      Use a RDS radio to check the digital information you provide.

  1. 6.      Do I need to pay for your RDS software at an additional cost?

No, You just need to purchase FMUSER RDS-A encoder and FSN series transmitter, we provide RDS software for free.

  1. 7.      What is the different between RDS fm radio station and general radio on the radio?

The following three images illustrate how RDS can be used on an FM radio station; the latter two were taken when the radio was tuned to Nottingham radio station Trent FM. All the images are of the display on the SonyXDR-S1 DAB/FM/MW/LW portable radio.

  1. 8.      What are the characteristics of the FMUSER RDS-A encoder, and what is the difference compared to innovonics RDS encoder?

Innovonics RDS encoder is a good products , The biggest difference should be the same function, and we offer more economical encoders.

Let’s look the the characteristics:

Explain

1

12V DC

Power supply connector. See section 3.3 for details.

2

Ethernet

Ethernet RJ-45 connector.

Use a standard (direct) cat 5 Ethernet cable for connection to the Ethernet switch, router or wall-socket.

The Ethernet control includes internal website (referenced as “Port 2”) and two independent user configurable general purpose ports (referenced as “Port 3” and “Port 4”) designated for remote control via TCP or UDP protocol.

The encoder operates also with no cable connected.

3 USB

USB standard B type connector. This port is referenced as “Port 1”.

Use the USB for initial setup of the encoder or for its local control.

The encoder operates also with no cable connected.

4 Output BNC

RDS signal output to transmitter, modulated at 57 kHz subcarrier.

If the Loop/Side switch is set to the LOOP position, the Output is a sum of the RDS signal and the signal fed to the Input BNC connector.

5 Input BNC

Optional input for synchronization to the pilot tone or for mixing the RDS signal with existing modulation signal.

6 Loop/SIDE

Allows the input signal to be added to the output signal.

7 GPIO

Optional logical inputs for direct control of some RDS services (TA, PROGRAM).

The connector is a standard 6-pin PS/2 type.
