DIY KIT 44 – FM Transmitter DIY using 3 transistors

This is yet another FM transmitter DIY kit for beginners and hobbyists. It is slightly different from our previous FM transmitters. It has 3 NPN transistors and the transmission range is around 50-100 meters.

It is an enhanced wireless microphone with excellent transmission quality. The voice transmitted by the microphone can be heard using an ordinary FM radio.

Frequency range: 80MHz-103MHz
Working voltage: 1.5V -9V
Range: More than 100 meters at 4.5V. For the general radio to receive the FM signal, users need to solder a 50cm wire to the kit.
