It integrates the 150W FM stereo transmitter exciter, power amplifier, output filter and switching power supply in a 1U high 19-inch standard case, reducing the connecting cables between the components.

Features:

• User-friendly digital LCD panel, using one rotary knob to control.

• The integrated LCD screen displays all the parametric including: transmitter frequency, stereo and mono, volume, amplifier tube temperature, audio signal UV meter, forward power, reflected power, modulation mode, pre-emphasis etc,.

• 1U 19-inch thickened all-aluminium case, strong and excellent heat dissipation.

• Precise PLL frequency generation system, to ensure that the frequency not drift away for more than10 years, with built-in high-quality stereo encoder.

• Outstanding power AGC balance control system, adjustable power output from 0 to 150watts, and automatic gain power control to maintain output power within set range without drifting.

• Signal input supports XLR and RCA audio inputs,  and also SCA and RDS signals using the BNC connector AUX.

• The RF amplifier uses LDMOS transistors to withstand even severe load mismatch exceeding the 65 : 1 VSWR at a 5dB compression point.

Frequently Asked Questions (FAQ)

1. What isRadio Broadcast Data System(RDS)?

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

RDS transmitted including time, station 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):

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.

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

3. What equipment do you need to build an RDS broadcast?

Here is A RDS FM radio transmitter equipment list:

1) FMUSER RDS-A encoder

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

3) RDS encoding software

4)  Antenna and cable with connectors

4. 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.

5. 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.

6. 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 Sony XDR-S1 DAB/FM/MW/LW portable radio.

7. 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.
