Here is a very interesting and simple FM transmitter used to transmit audio in the wide range up to 100M using only one transistor. The entire circuit of FM transmitter is divided into three major stages oscillator, modulator and amplifier. The transmitting frequency of 88-108 MHz is generated by adjusting VC1. The input audio generated by microphone is changed into electric signal and is given to base of transistor T1. Transistor T1 is used as oscillator which oscillates the frequency of 88-108.......

Does anybody home brew FM transmitters any more? Who knows? Your faithful editor tried several times back in the early nineties. First effort was building an AM unit from this schematic and it sort of worked - using a 1. 0 MHz XTAL it managed to get a block down the road at 790 KHz. It was a weak effort but it got me hooked.After several spectacular failures, the next successful effort was a.......
