FMUSER RDS-A 1500W 1.5KW RDS FM Radio Broadcast FM Transmitter with RDS Encoder DV2
dipole antenna+30 meters cable kit
FREQUENTLY APPLICABLE USES:
1). Community Radio stations
2). LPFM radio stations
3). City radio stations
4). Christian Church radio stations
1) OVERHEAT PROTECTION:
The transmitter will switch to auto-protection with alarm message and a beep sound once the working temperature gets higher than normal range.
2) OVER SWR PROTECTION:
SWR is the indication of antenna system connection with transmitter. Once the connection is bad and causing a high SWR Value, the transmitter will switch to automatic protection mode by showing alarm message on the screen with a beeping sound meanwhile.
3) FAN ERROR ALARM
When the fan stopped running, there will be alarming message showing on the screen like the following:
4) FREQUENCY AUTO MATCHING:
The 1kw FM transmitter auto scans the best matching frequency on antenna to maximize the broadcasting efficiency at minimum SWR ratio, this ensures the best performance from both the transmitter and antenna.
5) MODULATION ADJUSTABLE:
When audio mixers are connected with the 1kw FM transmitter through the XLR Balanced audio input interface, the transmitter will provide plenty of options for the modulation to best match with the mixer.
6) ONE TOUCH OPERATION:
This FSN-1000T 1.5kw FM transmitter is designed with a precisely sensitive touch screen in replace of the control buttons on previous transmitters. With all information displayed clearly on the screen, users can control and configure all parameters very easily.
7) FLEXIBLE AUDIO OPTIONS
The pre-emphasis of 1kw FM transmitter are flexible to choose among 0US / 50US/ 75US, users can choose the best match mode according to their own needs.
8) ADJUSTABLE POWER OUTPUT
The RF out of this 350W FM transmitter is continuously adjustable from 0-350 watt at the stepping of 0.1watt, which means you can tune it to 1w, 1.1w, 1.2w…50w…350w, with just one transmitter you’ll get multiple modes of outputs and easy to tune as per your needs.

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.
- 3. How is the RDS Alternative Frequency (AF) work?
Here is a video about ow the RDS AF replacement frequency works on youtube.
- 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.
- 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.
- 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:

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.
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.
Allows the input signal to be added to the output signal.
Optional logical inputs for direct control of some RDS services (TA, PROGRAM).
The connector is a standard 6-pin PS/2 type.
Now widely used in: 2G/3G cell phone coverage hotels, schools, hotels, railway stations, docks, office buildings, factories, residential quarters and other areas with wlan / wifi signal coverage, various wireless intercom system, short wavelength radio waves various ham frequencies are supported!
The cable supports:
The frequency 0-12G
Note: 1/2 what does it mean?
Is the outer diameter of the metallic shield of the feeder units of inches, regardless of the inner core and coaxial .1 / 2 refers to the outer diameter of the metal shield is 1.27 cm feeder 7/8 refers to the feeder outer diameter of the metallic shield is 2.22 cm, the outer insulation is not including.
Depending on the wireless transmission of electromagnetic waves in the frequency in the feeder, the attenuation of the signal intensity is different. For example: the electromagnetic frequency: 890 — 920M, attenuation at 1/2 feeder is: 7.5 – 7 .7dB/100 meters. 7/8 feeder attenuation of approximately: 4.2 – 4 .5/100 meters.
