SIGINT on a Budget - Listening in, Gathering Data and Watching for Less Than $100

Explore the world of low-cost signals intelligence (SIGINT) in this 51-minute conference talk by Phil Vachon and Andrew Wong. Learn how to build a robust and open SIGINT platform for less than $100 using a Raspberry Pi and software-defined radio (SDR) technology. Discover techniques for capturing, demodulating, decoding, and analyzing data across various parts of the radio spectrum. Gain insights into SDR-related design and development issues, as well as basic digital signal processing (DSP) concepts. Examine real-world examples of unencrypted wireless communications still in use for critical systems, based on data captured in midtown Manhattan. Consider the ethical implications and potential applications of this technology beyond SIGINT. Join Team MILK as they share their fascination with the unexpected order in the chaos of the airwaves and discuss their spectrum-capturing platform.
