One of our favorite purveyors of electronics knowledge is at it again. This time, [Afroman] explains how frequency modulation works while building up a short-range FM transmitter on a board he has ...
The range of this FM transmitter is around 100 meters at 9V DC supply. The circuit comprises three stages. The first stage is a microphone preamplifier built around BC548 transistor. The next stage is ...
The heart of every radio transmitter is a reliable oscillator. Creating small, and tunable, oscillators that can maintain a precise frequency when conditions like temperature, pressure or humidity ...
The circuit is a simple VHF FM transmitter circuit. It is basically a VHF Colpitts oscillator capable of transmitting sound or music to any standard FM receiver/FM Transmitter. The circuit is a simple ...
