 FMUSER FSN-1000R FM Radio Broadcast Relay System

OVERVIEW:
FMUSER FSN-1000R FM radio relay repeater is the latest product developed by FMUSER in 2019. The all-in-one product includes digital demodulation, digital processing and modulation, RF power amplifier, power supply, all modules in a 2U standard chassis, all signals both input and output from the rear panel.
FMUSER FNS-1000R FM radio relay system includes receiving antenna,FSN-1000R FM radio relay repeater, transmitting antenna, connecting cables and connectors. The FM signal can be received by the receiving antenna, the FSN-1000R FM relay repeater will do demodulates, processes, modulates, RF amplifies, and the transmitting antenna can directly broadcast again , this system can meet the needs of various occasions.
Many users also call it as local: fm relay station, broadcast relay station, relay transmitter, complementary station, broadcast translator, repeater, re-broadcaster.
 
I Already have a radio station, how to expand my fm transmitter coverage?
You can use the FMUSER FNS-1000R FM radio relay system to receive the FM signal of the main station and broadcast it again at the new station. The power of the FNS-1000R relay broadcasting system transmitter is 1KW, so the coverage of 50KM can be increased for each additional station. And the source of the studio program is exactly the same as the main station.
 
How to re-broadcast my station to whole country of 100KM-200KM with a limited budget?
The same principle is as above, five sets of FMUSER FNS-1000R relay broadcasting system can meet the demand, and reduce the waste of signal coverage in the unmanned area, only need to be placed in a densely populated place.
 
How to transfer the studio audio to the transmitter?
As we all know, STL can achieve this function, but STL must be accessible point-to-point transmission. If there is a mountain or other obstacles in between, you can use FM Transmitter to broadcast the audio from studio to transmitter, because the FM RF signal can be bypassed, and finally the FMUSER FNS-1000R repeater can receive high quality audio from the studio.
 
How to transfer studio source to transmitter stations in different locations?
STL can only be point to-point. If there is a one-to-many point, multiple sets of STL systems must be used, and the price is high, the installation is troublesome, and it is seriously affected by the environment. Now we only need to install the FMUSER FNS-1000R relay broadcasting system at different transmitter sites, which solves the problem of program transmission and also solves the problem of broadcasting stations, because FMUSER FNS-1000R is not only a receiver but also a broadcaster.
 
In short, FMUSER is always working on the most economical, stable and reliable system solutions to solve customers' problems in broadcasting.
The FMUSER FNS-1000R relay system has many other main features as follows:
 
MAIN FEATURE
1. Adopt digital FM receiving and demodulating technology to ensure clear demodulation sound quality.
2. Using FPGA+DDS technology to implement full digital FM modulation technology, so that the FM emission index reaches the top level.
3. Using high reliability ARM architecture microprocessor technology as the main controller.
4. Support input of wireless RF receiving audio, two AES/EBU digital audio signals, one analog stereo audio and one MPX stereo composite signal, etc.
5. Support one way RDS or SCA input.
6. AGC controls output power to ensure zero deviation of output power.
7. Perfect over-current, over-voltage, over-temperature, over-power, standing wave ratio alarm and protection function.
8. Using OLED to display working parameters in real time.
9. Use high-gain directional FM receiving antenna to receive signals (even the signal is very weak ) and and re-broadcast .
10. Re-broadcast power up to 1000W, with high gain dipole antenna, cover radius up to 50KM.

FAQ
1. What is the radio relay system?
-- The radio relay system is for receiving and re-broadcast of the main radio station signal.
2. Why the relay radio station can not broadcast same frequency with the main radio station ?
-- Because the coverage of the transmitter is a circle, the overlapping parts of the two circles will have the same frequency interference. Sounds like a repeating sound.
3. How much is the difference between the main station and the relay station?
--Minimum difference of 0.5mhz. 
4. How many meters should between the receiving antenna and the broadcasting antenna?
-- At least 3 meters apart.
5. How much delay?
- The delay between the main station and relay  stations is 0.1 second.
6. Whether the audio input can be switched automatically?
-- Does not support automatic switching.
7. What advantages does the radio relay system has over STL?
* No receiver limit.
* The signal is more stable and can adapt to more complex environments.
* There are two receivable frequencies that can be used.
* The operation is simpler, there are not many setup options.
8. What is the difference between fm relay station and synchronous broadcast?
The fm relay station converts to an audio signal by receiving a signal from the FM main station and transmits it again.
Synchronous broadcasting requires independent audio transmission lines, such as optical fibers, networks, microwaves, satellites, etc. to transfer the audio signals. 
The fm relay station requires at least two frequency points for continuous transmission and coverage.
Synchronous broadcast only needs one frequency point to cover.

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
