Build Your Own 90MHz Crystal Controlled FM Transmitter: A crystal controlled FM transmitter is a radio frequency circuit that uses quartz crystal oscillator to generate a stable, precise frequency for FM transmission

Audio compressor for microphone

This circuit diagram illustrates an audio compressor for microphone signals. Its primary job is to even out the volume of your voice, making soft sounds louder and loud sounds quieter, resulting in a more consistent and professional audio output. This is incredibly useful for podcasts, voice overs, amateur radio, or any application where microphone levels can fluctuate.
