Make Your Own Low-Power AM Radio Transmitter
Materials and Equipment
Supplies for this project are available in one convenient kit from the Science Buddies Store
To do this experiment you will need the following materials and equipment: * Crystal oscillators (2), notes: * Each oscillator should be at a different frequency, within the AM broadcast band (0.53 to 1.71 MHz in North America, 0.53 to 1.61 MHz elsewhere). * For use with the solderless breadboard in this project, you want the 'full can' package. * Solderless breadboard * 1000 ohm to 8 ohm audio transformer * 1/8 inch mono phone plug * 6 V AA battery holder (holds four batteries), * 1.5 V AA batteries (4) * Alligator jumpers * Jumper wires for breadboard.

Building the Circuit
Before we get into the step-by-step instructions for building the circuit, we'll first go over the circuit design and show you how the solderless breadboard works.
