Convert Radio Waves to Bits (RF Demodulation) By Nate Singer “In this video, I go over how to take a device that emits wireless signals and convert the RF waves back to binary bits--1's and 0's. For longer than I'd like to admit, I had no idea how to convert radio frequency signals back to the data they originated from. Finally, I sat down and worked it out... now I'm here to share it with you. Starting off, we will use GQRX to locate the carrier, gnuradio-companion to record the energy to a file, and then Inspectrum to inspect the electromagnetic wave, converting it back to the originally transmitted information. If you have any questions or run into problems, please comment below and I'll do my best to get back to you to help with some troubleshooting actions. I hope this allows someone to find a cool bug and get paid out significantly in bug bounty, or regardless create a more secure autonomous world based on radio signals, as devices rely on electromagnetic waves in increased capacity every day.
