How to Make a Fm Stereo Transmitter - DIY Hifi Transmitter
I recently made a simple DIY FM transmitter kit for electronics hobbyists and beginners. With this DIY kit, you can transmit your voice or audio on regular FM radio in the FM broadcast band.
You can use this FM transmitter in two ways:
a. Audio transmission using the electret microphone: You can transmit your voice on FM radio with the electret microphone. You can also place the transmitter circuit near any speaker so that the microphone picks up the sound and transmits it to the tuned FM radio.
b. Audio transmission connecting the stereo jack of the speaker to the audio source: For better sound, you can connect it to your computer, iPod or mp3 player using a speaker jack. Audio from your music players is transmitted to your nearby radio.
Features :
Frequency range: 88-108MHZ (frequency can be changed by moving the inductor).
Working voltage: 1. 5V-9V
Transmission Range: More than 30 meters in open area. The transmission depends on the length of the antenna used. I used a simple 10cm long wire. The signal can be transmitted even far with a longer antenna of about 50cm.
