How is fm radio transmitter

These types of transmitters, however, are far less powerful than those that power your favorite FM radio stations. What is a Radio Transmitter? A typical FM radio broadcast transmitter that is used in FM broadcasting contains the following components: The power supply provides an electrical signal to operate the transmitter.

The oscillator creates the alternating current, a carrier wave, that the transmitter sends through the antenna. The modulator adds information to the carrier wave. Below this, wait for the screen to update and display your car audio system, selecting it to pair. The cool thing about Bluetooth is that it will pair automatically in future; the not-so-cool thing is the impact on battery life, resulting in you keeping your phone charged while using it.

You do have one other option and that is to use an FM transmitter, although how you achieve this depends on the hardware. Some Android phones come with built-in FM transmitter functionality, in which case you can use this natively or with a free app such as Quick FM Transmitter and then broadcast the MP3 and other audio files on your phone to your car radio.

Typically this will work in a similar manner to the analogue cable solution, although the FM transmitter may require exclusive access to the in-car charger. The device you can use and what frequency the transmitter broadcasts varies from model to model, so you'll need to familiarize yourself with the built in specs beforehand.

When you have this figured out, you can begin making your broadcast playlist or personal podcasts. Once your modified transmitter is put together it should be able to send out radio waves, but before you go live you'll want to check. Connect the transmitter to your device and turn them both on.

Then tune your radio receiver to the frequency on the transmitter. If you did everything correctly, you should hear the audio that is playing on your connected device. To test the broadcast radius move your transmitter farther and farther away from your receiver, once the audio starts fading out, you have found the transmitter's limit. That way nearby cars will know what frequency to tune into to hear your broadcast.
