Default Re: FM to AM converter - variation on a theme!

"Have you connected a digital FM module to the modulator Nigel, or at this stage, just built and tested the modulator?"

Not an FM unit, just wired it too the headphone output on my bench CD deck and it worked very well with a range of about 3 feet with a length of about 2 ft of wire as an aerial. Also the 9 volt battery was down to around 7.2 volts giving me 5 ish after the resistor.
