The Raspberry Pi is a rewarding platform for radio amateurs, and here at Elektor we’ve paid attention to it a number of times already. But there is a deep knowledge gap between the world of amateur radio and the Raspberry Pi. Dogan Ibrahim, himself a licensed amateur radio operator for decades and also the author of numerous books on the Raspberry Pi, brings the two worlds together in his new book Raspberry Pi for radio amateurs.
It is important to take the title at face value: it is a book intended for radio amateurs with little or no knowledge of the Raspberry Pi. If you already have experience with the Raspberry Pi, you You will probably be disappointed because half of the book is not about radio at all, but about the different Raspberry Pi models, how to install the Raspberry Pi operating system, how to use the command line and how to use the desktop. and programming of GPIOs. But if you’re an amateur radio who wants to take their first steps into the world of Raspberry Pi, the audience this book is aimed at, then this is a great opportunity to explore the minicomputer in more detail.
The more you read the book, the closer the projects get to the world of amateur radio. These projects require some knowledge of the Python programming language. You learn to control a relay to turn equipment on and off, on time, GPS coordinates or display sensor measurements on a small LCD screen and generate waveforms. A frequency counter, FM transmitter, and RF power meter are also discussed.
The most interesting subjects of the book are described at the end. The chapter on RTL-SDR is a good introduction to using software-defined radio with the popular RTL-SDR dongle and more powerful alternatives. In the last chapter, the author discusses a dozen interesting software for radio amateurs, but it is a shame for many that it is limited to installation instructions and a brief explanation of how to use them. Still, overall, the book offers a good overview of the functionality of the Raspberry Pi for radio amateurs, and it provides a sufficient foundation to learn more about yourself. An affordable pack with the book and the RTL-SDR kit is available on the Elektor Store.
