HackRF Libri GmbH The Complete SDR & RF Engineering- HackRF One Bible

Right now, invisible signals are flooding the space around you-aircraft transponders whispering to control towers, garage door remotes firing bursts of data, emergency broadcasts waiting on standby frequencies, and encrypted packets racing through the air you breathe. Most people live their entire lives blind to this hidden electromagnetic world. You don't have to be one of them.
The HackRF One Bible is the definitive hands-on masterclass for anyone who has ever pointed an antenna at the sky and wondered, What am I actually looking at? Whether you are a ham radio enthusiast itching to explore beyond analog voice, a maker hungry for real RF projects, or a cybersecurity student preparing to map wireless attack surfaces, this book takes you from complete novice to confident operator-without drowning you in engineering calculus or assuming you already own a lab coat.
>Your antenna is already picking up secrets. The only question is whether you know how to listen. Power up your HackRF, open this book, and finally see the invisible world that has been surrounding you all along.
