Default Re: Mini FM transmitter as a signal booster.

Before the little low-power FM modulators were legalised about ten years ago or so I found that if I modulated an FM oscillator with the output of the FM radio receiver - with the requisite 50us HF boost - it also broadcast the stereo pilot signal and the stereo difference signal from the FM transmission.

At the time I wanted to hear Jazz FM in London on 102.2MHz which was a very marginal signal at home and it provided a good level of stereo signal into any radio within the home and garden quite nicely.
