FM transmitter with 5 meters to 100 meters transmission range: Here's one of the easiest and simplest FM transmitter for amateur and electronics beginners. With this DIY kit, you can transmit your voice or audio over an ordinary FM radio within the FM broadcast band.   Besides, this kit is not only capable of transmitting voice using microphone but also transmitting music from your music player.You can use this FM transmitter/microphone in two ways: a. Audio transmission using electret microphone: You can transmit your voice to FM radio with the electret microphone. You can also place the transmitter circuit close to any loud speaker so that the microphone picks up the sound and transmits to the tuned FM radio. WATCH THE EXPERIMENT VIDEO ON YOUTUBE b. Audio transmission connecting speaker stereo jack to audio source: For hearing better sound, you may connect it to your computer, ipod or mp3 player using a speaker jack. The audio of your music players get transmitted to your nearby radio. WATCH THE EXPERIMENT VIDEO ON YOUTUBE Features: Frequency Range: 88-108MHZ (Frequency can be changed by moving the inductor coil). Operating voltage: 3V-9V Transmission range: More than 100 meters in open area. Package contains: Electret microphone. Transistor(Q1)- S9018.  Download S9018 datasheet R1- 2.2K R2- 22K R3- 2.2K and 1K. For short range transmission (5 meters), use 2.2K Ohm resistor. For longer transmission (100 m), use 1K Ohm resistor. We will send both resistors. Use it according to your use. The more the resistance, the less is the transmission distance. R4- 33 Ohm R5- 33 Ohm C1- 0.1uF(Code- 104). C2- 0.1uF (Code- 104) C3- 680pF(Code- 681) C4- 30pF(Code- 30). This capacitor contributes to the FM transmission frequency. C5- 10pF(Code- 10) C6- 30pF(Code- 30). Coupling capacitor connected to the antenna of the kit.
