Consider Your Budget


The budget issue is very important. Because your budget determines the scale of your radio station. When you are considering your budget, you should determine how much budget is allocated to each piece of equipment. Then you can confirm the budget for buying an FM radio transmitter. At last, you can check if the purchase budget is reasonable and if it can meet the requirement of running your radio station normally.


The Functions of the FM Broadcast Transmitter


It is no doubt that the functions of the FM broadcast transmitter are the top priority. Because FM radio transmitter is the core of a radio station, if it has a poor performance in functions, your radio station can't work normally. And we think these five key points are the most important, the transmitting power, the range of frequency response, the quality of audio signals, the audio functions, and safety protection programs.

Enough Transmitting Power

The number of listeners your can serve depends on the coverage of your FM radio transmitter. Here are some rough data for reference when you are trying to determine the transmitting power of the FM transmitter. A 50w FM transmitter can cover a radius of about 6 miles. A 100w FM transmitter can cover a radius of about 10 miles.


Extra share: The transmitting power of the FM broadcast transmitter is not the only parameter that affects the coverage. Weather, the height of the transmitting antenna, the obstacles, etc. all affect the coverage as well.

Appropriate Frequency Response Range

Do you know that different countries have different regulations on FM frequencies ranges that can be used legally? For example, it uses an FM frequency range of 76.0 - 95.0 MHz in Japan. Some countries in Eastern Europe use an FM frequency range of 65.8 - 74.0 MHz. Most countries all over the world use an FM frequency range of 87.5 - 108.0MHz. Therefore, you need to choose the FM broadcast transmitter with an appropriate frequency response range based on your local regulations.

Excellent Audio Functions

If you want to provide your listeners with ultimate hearing experiences, you should choose those FM broadcast transmitters with various audio processing functions and being able to transmit high fidelity and low loss audio signals. You can focus on these technical indicators: Pre-emphasis, SNR greater than 40dB, Stereo separation greater than 40dB, and Distortion less than 1%. These technical indicators can help you to choose an FM radio transmitter with excellent audio functions. If it is a little abstract for you, let's take an example, FU-50B 50w FM transmitter from FMUSER. It performs well in drive-in broadcasting services, community radio, and school radio as its excellent audio functions.

Reliable Safety Protection Programs

Your FM radio transmitter probably will work continuously for a long time, which will increase the possibility of the equipment breaking down. Therefore, selecting an FM radio transmitter equipped with safety protection programs can reduce the possibility of equipment damage and your use cost. 

The Matched Equipment

Generally speaking, only a single FM broadcast transmitter can't work normally. You need other matched equipment to work together with the FM radio transmitter. Here are the lists of equipment used in some common scenarios.
