2. Features:
2.1 Modern, High Efficiency, Digital High Power FMUSER AM Transmitter
Adopt digital modulation method
Over 73% overall efficiency, significantly reducing electricity costs

15-inch intuitive touch screen interface, which can realize all function control, simple and convenient operation
Each FMUSER AM transmitter includes an output matching network that allows the transmitter to be tuned to maximize efficiency to accommodate changes
Equipped with accurate RF and audio spectrum analyzers, real-time monitoring of operating index
New standard in compact AM design, more efficient use of space
2.2 High-efficiency power supply to save energy and protect the environment
Superior efficiency design and low maintenance make this FMUSER AM transmitter extremely cost-effective to own and operate, with an overall efficiency of 73% or better. High efficiency means less energy is wasted as heat, and an air-cooled system using a fan also reduces power relative to the power consumption of the transmitter, reducing cooling and ventilation costs. Depending on its transmitter size and your local electricity bill, the resulting electricity savings can run into the tens or even hundreds of thousands of dollars over the lifetime of your transmitter. High efficiency also reduces thousands of metric tons of greenhouse gas emissions over the entire life cycle of the FMUSER AM transmitter while protecting the environment. The main power supply adopts thyristor full-wave rectification, and the main power supply adopts thyristor full-wave rectification, with phase loss protection function, phase sequence monitoring protection function, standing wave protection, overcurrent protection, wind protection, and high temperature protection. , Arc monitoring function. At the same time, three power levels of transmitter high power, medium power and low power can be adjusted.
2.3 First-class space utilization
FMUSER AM series transmitters are typically one-half to one-quarter the size of comparable high-power medium-wave transmitters. This makes planning your FMUSER AM transmitter deployment easier and gives you flexibility. While FMUSER AM series transmitters may be compact inside, they still offer easy and spacious access to all major serviceable components and modules, ensuring easy maintenance.
2.4 Advanced and easy-to-control touch screen and remote access control system
Each FMUSER AM transmitter includes remote control software (AUI) with network access and each FMUSER AM transmitter features a 15" touch screen display. Whether you are at the transmitter site or surfing the Internet at home, the 100% remote AUI helps you manage your transmitter, with hundreds of parameters available in real-time and at your fingertips. Imagine knowing in advance what parts and tools you will need in the transmitter field. Remote control can help you avoid travel, saving time and money. Its network communication interface and serial communication interface are (RS232 or RS485/RS422), in addition to remote operation, data acquisition can also be performed.
2.5 Real-time built-in meters
FMUSER AM series transmitters come with complete built-in meters and can cost tens of thousands of dollars if purchased separately.
These include real-time impedance measurement, voltage, current, power technology, which allows optimization and monitoring of antenna system load impedance while the transmitter is operating normally. Compare the transmitted voltage and current waveforms to measure the load impedance over the operating frequency range.
Because the system can measure impedance without the need for manual frequency sweeps, the antenna system impedance trace can be measured without turning off the radio. Impedance is measured at the combiner, so no correction for harmonic filter phase is required.
The FMUSER AM transmitter also includes a built-in directional coupler for spectrum measurements. Traditionally, transmitters have used voltage or current sensors. Directional couplers increase the accuracy of spectral measurements into the actual antenna loading, which is important when measuring adjacent channel emissions.
2.6 Easy to operate, reliable and easy to use
As with all FMUSER FM transmitters ever manufactured, the FMUSER series integrates solid state components in a rugged, highly redundant, hot-swappable architecture. The compact footprint, published parts list and screwdriver replaceable power keep your FMUSER AM transmitter running for years to come. A unique feature of the FMUSER AM transmitter is a complete replica of the exciter section that provides the RF carrier and modulation control signals to the power module. In the event of a failure, the transmitter automatically switches to a built-in backup exciter, significantly improving the high operational reliability inherent in the modular solid-state design. It can maintain live broadcast without manual supervision, adopts a unique circuit, which can dynamically stabilize the power supply, prevent the AC line voltage from changing, and automatically restore the previous operating state after AC power failure, overvoltage or RF overload, without special tools or Quick and easy frequency change capability is available with external test equipment.
2.7 Highly intelligent security mechanism system
The security device consists of a mechanical key-controlled access system that ensures power is removed from the transmitter cabinet and the antenna is grounded before access is allowed. A fail-safe emergency shutdown system is included, allowing the addition of an unlimited number of series-connected safety shut-off switches. Any loss of electrical continuity in this loop will automatically cause the main AC circuit breaker to open, removing all power to the transmitter cabinet.
2.8 Rock-solid reliability design
The welding and connection part of the power amplifier board adopts the whole board gold plating process, which ensures good electrical performance and anti-oxidation and corrosion resistance. The body of the transmitter adopts an anti-radiation case and a shielding structure. Except for the skeleton, it is an all-aluminum case, which meets the requirements of electromagnetic radiation. Fan airflow is unaffected by changes in AC power, further ensuring low temperature operation and long-term reliability. With master-standby switchover, it automatically switches to the standby machine when the host fails.

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
