However, this transmitter is low power and low fidelity, so the simple set up is more than adequate. This isn’t the first time we’ve looked at AM transmitters. Any of these would make a nice ...

This transmitter is basic but allows transmission of audio to an AM radio. It consists of an RF oscillator operating in the AM broadcast band, together with a modulator stage, which mixes the incoming ...

An AM transmitter is simple enough, in this case an oscillator and buffer driving a class C power amplifier. The modulation is applied by a transistor in series with the power amp, driven from an ...
