Here are some DIY FM Transmitter circuits that we have been published on electroschematics.com. This do-it-yourself fm transmitters are pretty easy to build and will give you a good feeling when ...

testing two popular 555 transmitter circuits. One uses the control voltage pin to input the audio signal, while the other uses the reset pin. The CV-pin version worked slightly better, but it was ...

Here is a simple USB FM transmitter that could be used to play audio files from an MP3 player or computer on a standard VHF FM radio by connecting it to an USB port. The circuit use no coils that have ...

Likely you know that the vacuum tube amplifier stage has fairly high input impedance; but because the transmitter input standard is 50 ohms, an impedance matching network is necessitated in the design ...

For many years, AM transmitters used vacuum tubes for the power amplifiers and for the driver circuit. A simplified AM transmitter circuit is shown in Fig. 1. The DC high voltage connects to the PA ...

After flying and crashing a cheap FPV drone for a bit, [GreatScott] decided to try his hand at building his own video transmitter ... experiment with a simple circuit built from discrete ...
