To build this simple radio transmitter, you will need to gather the parts such as a 9V battery, a clip, wires, a prototype board, a trimmer capacitor, a resistor, an audio plug, etc. From tools, ...

Sometimes, it is useful to transmit a low-power radio signal to create a beacon, to send a signal carrier to a near receiver, to transmit in QRP or QRPP mode, and so on. The circuit shown here is very ...

[gpsKlaus] built this little FM radio (translated) based on the AR1010 IC. That chip is controlled via I2C by an ATtiny45 microcontroller. His tuning implementation relies on presetting 16 stations in ...

The variable capacitor C1 and L1 will constitute the tank circuit which will produce the high frequency signal, the capacitor C1 is variable so that we can produce different frequency signal by ...

Legendary radio personality and programmer Scott Shannon sat down for what he said was his first-ever webinar on Thursday to share his lessons learned and insights on modern radio with Benztown‘s ...

In the video below, the process of making this simple radio FM transmitter is explained in details. The project starts with wiring the mono phone plug to an audio source like an mp3 player. Once ...
