Simple AM radio using MK484 IC

This is a simple AM radio receiver that use an integrated circuit chip called the MK484 as the main component. This simple radio will run on one AA battery using an earphone. I show it here connected to my homemade amplifier that requires 3 volts. This is a stand alone device that doesn’t require an external antenna or an earth ground to function. Circuit diagrams using the MK484 can be found by doing a Google search for MK484.
