How can I make a simple radio transmitter using amplitude modulation?

I am only trying to understand how it works so make it simple and describe why you say what you say.

Dr: that's a receiver, not a transmitter.

http://en.wikipedia.org/wiki/Amplitude_modulation

has a circuit

http://www.cappels.org/dproj/LPAM/4mmo.htm

is another.

Search google for "amplitude modulation schematic" and you will find hundreds.

FCC has severe limits on how much power you can broadcast. Don't remember, perhaps 1/2 watt?
