One Chip AM Radio
This is a complete AM radio for the standard broadcast band, most of which is on a single IC. Other components, such as the coils and variable capacitor to make a finished radio, are included. The IC is the RF amp, detector and AGC circuitry. The IC’s output drives a two stage, transistor audio amplifier and 3" speaker. Operates from 9 volt battery. A good kit for beginners to see and build.
