Build a web-connected software-defined receiver with OpenWebRX+ software, a Raspberry Pi, and an RTL-SDR USB stick. Explore and share the radio spectrum!

Designed for curious beginners and experienced radio hobbyists alike, this hands-on guide walks you through every step: setting up your Raspberry Pi, installing OpenWebRX+ connecting your SDR hardware, and configuring your receiver to explore everything from AM/FM broadcasts to shortwave and amateur radio, and data transmissions everywhere. You'll learn about radio signals, where they lurk, the secrets they hold, and how to uncover them. The fun doesn't stop there: you can open your Open WebRX+ receiver to the world, so you and your friends can tune in on your mobile devices, from anywhere on the planet.

What You Need
You will need a copy of the free OpenWebRX+ software, and a computer to run it (we'll use a Raspberry Pi); an SD card and card writer; and SSH client software to communicate with the Pi. For the radio hardware, an inexpensive RTL-SDR dongle is a good start, though OpenWebRX+ supports other platforms. An antenna is essential: the type will depend on what you want to listen to, but an inexpensive VHF/UHF dipole kit will get you started, or even a long piece of wire.


Who Is This Book For?
You don’t need to be an electronics or radio expert to play here, nor a computer whiz; if you know your way around a Linux terminal, that’s great, but if not, follow the examples and you’ll do fine. Along the way, we’ll have short, simple projects to build understanding and skills. My aim here is to get you up and running OpenWebRX+ with minimal fuss, so you can explore at your leisure and expand your horizons as you go.
