In the 1880s, the scientist ( and legendary sourpuss) Heinrich Rudolph Hertz proved the existence of radio waves (hence why the unit of frequency, the Hertz, was named for him). We encourage you to do some research HAM Study by Signal Stuff is a solid resource for practicing HAM radio test questions and eventually earning your license. However, getting your HAM radio technician license will help you to learn and use the important concepts needed for radio hacking. ![]() You do not need a license to receive only to transmit – and RTL-SDRs are receive only. ![]() NOTE: We will not be covering HAM radio specifically. And finally, we’ll show you how you can begin reverse engineering radio signals once you have the right foundation in place. Then, we’ll go into demoing the software so you’re set up for success. In this article, we’ll review the hardware and software components you need for a functional SDR setup without spending a fortune. With the widespread introduction of RTL-SDR devices, the barrier to entry for SDR has lowered substantially – quality low-cost equipment is now more affordable and accessible. However, in the last several years some smart people figured out that a Realtek chipset used in TV tuner dongles could be repurposed as a cheap, multifrequency receiver. So you want to expand your hacking repertoire and to play around with different radio protocols aside from the more ubiquitous Wi-Fi and Bluetooth? Software-defined radio (SDR) can open an entirely new world to you different radio frequency (RF) bands serve different purposes ranging from submarine communications to satellites in deep space.Įven as recently as a decade ago, becoming an SDR enthusiast was difficult due to the exorbitant costs associated with SDR devices (which could easily stretch into tens of thousands of dollars). ![]()
