What You Need to Know Before Starting an FM Transmitter

 

Attention: Please make sure that the antenna is connected before starting any kind of FM Transmitter. Or the FM transmitter might break down easily.

 

  • Connect the antenna - The first and most important point is to make sure the antenna is connected before starting the transmitter. If the antenna is not connected well, the energy won't be radiated. Then the FM transmitter will generate a lot of heat in a short time. 
  • Mount the antenna - The higher you mount your antenna, the farther away your signal will go. To avoid transmitting too far, just place your antenna just as high above the ground, that will give you a good, but limited signal to cover only your intended area.
  • Apply for a license - Please check with your local telecommunication authorities. In most countries require a time litmited low power broadcasting license. In case, your country accepts use of this kind of equipment without license, it is up to you to find an available frequency on the FM channel. When tuning the frequency, there should be a total silence of any other FM signal. Moreover, do not operate with full power so that do not cover a field or small festival area.
  • Balance the stereo - You can connect a balanced Left and Right stereo signal at the back of the transmitter, via the two XLR female input. Make sure you have correct audio level.
  • Enable the CLIPPER - It is a good idea to enable the CLIPPER functionality, to avoid overshooting modulation.
  • Check the pre-emphasis
  • Place your antenna on the ground - When assembled, your antenna must look like this: You can place your antenna on the ground, on a tube, but to cover a field or close open space, you do not need to mount the antenna on top of anything, unless you want to cover a wider area.
  • Final test - After everything is OK: check whether the antenna or the power supply or other cables are connected and ready. Grab a radio as an FM receiver, and an MP3 audio player as a signal source, play something stored in your MP3 and tune the FM frequency button to match the frequency on the FM transmitter, and listen if there is any unpleasant voice occurs, don't stop your frequency tuning until they all sound clear.
