AM/FM Radio Kit
The Elenco AM/FM Radio Kit (AMFM108CK) guides students through building a working superheterodyne receiver that picks up standard AM and FM broadcast stations. It is a classic project for understanding how radio receivers process signals, stage by stage. The kit comes with a 56-page training course split into nine lessons. Students build and test the radio in two parts, first the AM section and then the FM section, covering the audio amplifier, AM detector, AM IF, AM amplifier, mixer and oscillator, FM detector, the two FM IF stages and the FM RF stage. A transistor module lets learners switch between a modern integrated circuit audio amplifier and the original transistor design, so they can compare the two approaches. The kit includes the components, transistors, an LM386 integrated circuit and a mounting stand for the finished radio. It requires soldering and one 9V battery, which is not included. It is well suited to secondary-school electronics and physics classes as an extended, multi-lesson project.
