Making A Transistor Radio ... the crystal set with its coil wound on a ferrite rod. My first radio. In fact, my first electronic circuit. It is easy to believe these days that children are ...

A simple AM transistor radio can be made with surprisingly few components, but for a circuit with a reasonable performance they suggest six transistors to be the optimal number. If we think about ...

1. Work in groups of three or four. Assemble the circuit shown in the diagram. Match the leads on the transistor to the diagram, and identify the base, emitter, and collector. Check with your ...
