    Frequency Question (FAQ)
    1. What is Radio broadcast data system(RDS)
    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).
    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:
    The most important features is AF, TA, TP, it help FM radio station do more…
     a) RDS Traffic Announcement (TA) :
    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.
    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
    5. How can I build my rds channel on my Existing transmitter system?
    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.
    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.
    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.
    Lets look the the characteristics:

    How far(long) the transmitter cover?

    The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.

    EXAMPLE 5W FM Transmitter use in the city and hometown:

    I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).

    I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).

    I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).

    Below are the approximate range of different power FM Transmitters. ( The range is diameter )

    0.1W ~ 5W FM Transmitter :100M ~1KM

    5W ~15W FM Ttransmitter : 1KM ~ 3KM

    15W ~ 80W FM Transmitter : 3KM ~10KM

    80W ~500W FM Transmitter : 10KM ~30KM

    500W ~1000W FM Transmitter : 30KM ~ 50KM

    1KW ~ 2KW FM Transmitter : 50KM ~100KM

    2KW ~5KW FM Transmitter : 100KM ~150KM

    5KW ~10KW FM Transmitter : 150KM ~200KM
