How to Build an AM Radio Receiver - Circuit Basics
https://www.circuitbasics.com/what-are-am-radios/
The first AM radio has no amplifier and only relies on resonance to create sound. The second AM receiver has a transistor amplifier, and the final AM receiver circuit uses an LM386 amplifier chip. Introduction to AM Radio Receivers Medium wave is a band of radio frequencies extending from 530kHz to 1700kHz.
AM Linear Amplifiers
http://www.w8ji.com/am_linear_amplifiers.htm
Traditional linear AM amplifiers are a form of efficiency modulation. This occurs because supply voltage is constant and does not vary with modulation. With fixed high voltage, only the supply current varies with drive. When we vary current in a device with …
