For a long time, radio construction was the first step into electronics. Meanwhile, there are other ways, especially via computers, microcontrollers, and digital technology. However, the analog roots of electronics are often neglected. Elementary radio technology and easy-to-do experiments are particularly well suited as a learning field for electronics because you can start with the simplest basics here.
But the connection to modern digital technology is also obvious, for example, when it comes to modern tuning methods such as PLL and DDS or modern DSP radios.
This book aims to give an overview and present a collection of simple RF projects. I would like to support you to develop your own ideas, to design your own receivers and to test them.
