Using Your FM Transmitter Using the FM transmitter is fairly easy providing that an external FM receiver is available. Here are some suggestions for you to make your FM Broadcast Transmitter works in a longer range. Then slowly vary in that area, when transmitter and receiver frequency matches you can get the clear output from radio. here we use ta2003p ic using this ic you c... How to make powerful 4G antenna easy at home In this project we learn How to make powerful 4G antenna easy at home. 100nf Ceramic capacitor x1. In order to transmit the audio signal to the longer distance, we use modulation technique. in this project we use simple one ic. This tutorial is for making simplest FM transmitter using only one transistor. Connect 1,2,4 and 6 number pin with each other. Do not choose radio frequencies that are being used by local radio stations. Typical FM transmitter design’s normally comply with the block graph below Fig. Today i have come up with FM transmitter circuit which has a range of about 3 Km approximately. Now Connect voltage regulator 3rd pin with positive, 2nd pin with ground wire. The FM transmitter is a simple device that converts audio sound ( like your voice, audio player sound,) into a radio signal. By tuning the frequency, making of FM transmitter is completed. This signal can be modulated and used as FM transmitter. How to make Arduino Video Game . Then, with a non-conductive tool, adjust the capacitor for the clearest reception, rotate it till the receiver receives a sound from the microphone of transmitter. Make sure the shield wire does not touch the center wire. The simple FM transmitter is built around low-power audio amplifier using LM386 (IC1), transistor PN2222A (T1), 30MHz crystal (XTAL1), varactor diode 1SV149 (D1) and a few other components.
