This document discusses software defined radio (SDR) hacking and provides steps to solve real-world problems using SDR. It begins with an introduction to SDR hardware and software. It then outlines seven steps to SDR hacking, including tuning a receiver to the right frequency, finding the correct modulation, demodulating the signal, finding the clock speed, decoding using tools like Universal Radio Hacker, and implementing a solution. The goal is to use SDR to solve problems without illegal activity.
