(not exactly standard wireless) FM transmitter using OSCTUNE

It's funny, that you can set your Main oscillator to 88..108MHz (using FRC and PLL), route it to REFOCLK output pin, then sample analog input @22KHz (to say) and use the ADC output to change OSCTUN and... voilà, an FM transmitter is done!
(of course, the output is not exactly a sine wave but... )

It does work and... well, just a simple idea. Try it!
