Raspberry pi as radio point

When you have a Raspberry Pi lying idle at home, you willy-nilly think about what else it can do. I often rummaged through the Internet in search of interesting projects. Once I came across the pi-fm project, where it was said that you can create your own radio station for broadcasting music. Of course, such a radio point is limited (and not only by laws, but also by the power of the outgoing signal).

I decided to conduct an experiment and launched this project on the Raspberry Pi zero (https://github.com/rm-hull/pifm) and, along the way, power the raspberry from the power bank in the car. Since my car is a purebred Japanese with 30 years of age, the frequencies here are not standard - 76-90 MHz. To my surprise, even at these frequencies, the radio worked flawlessly. Of course, the quality (also mono broadcasting) wanted the best, but it’s still better than listening to the rattling of the body from our roads … I played a little and stopped using it, because I found the option to connect the line output directly to my car.
