How to Make AM Radio Transmitter

How to make an AM radio transmitter for use with a crystal radio or a normal AM radio. This simple circuit uses an oscillator chip and a transformer to take input from a sound source and turn it into radio waves, transmitted using an antenna. I test it with a CD player as the sound source but it may also work with an iPod or iPhone, though it may need some amplification for that.

WARNING: Do not transmit more than 1 or 2 meters/yards otherwise you'll interfere with other radios. In many countries it is illegal to transmit without a license.
