Harry Lythall has designed an FM Transmitter circuit that operates between 88 and 108 MHz - the commercial FM broadcasting band.
The transmitter is not Harry's first. In fact, Harry Lythall is pretty famous on the internet for his radio broadcasting circuit designs.
This transmitter is a wideband circuit design that outputs 150-300 milliWatt (mW) depending on DC voltage supply. According to the page, 9 volts delivers 150mW and 12.5 volts delivers 300mW, with a VARICAP modulation technique, and the possibility to add a synthesizer (thus making it a PLL [Phase Locked Loop]).
If you have some kit building experience and you want to build your own FM transmitter, or an oscillator (exciter) for a powerful amplifier, then this is exactly what you should need.
