“One of the points I’ve stressed for a long time is the value found in using simple equipment to the maximum of its potential. Whatever it might be, optics to weapons to electronics, my own combat experience has fostered an appreciation for Keeping It Simple, Stupid. And that’s the very paradigm I teach my classes from- taking what’s common and simple to understand and learning the techniques of using it to its peak potential. The same is true for building signals intelligence capabilities among preppers and/or potential partisans. Not that long ago the RAND Corporation published a white paper on the very topic; what they found was that not only does the capability exist to monitor most real-world threats in any given environment, anyone can do it.”
During our market scan, we found examples of SIGINT capabilities outside of government that are available to anyone. The capabilities we found have applications in maritime domain awareness; radio frequency (RF) spectrum mapping; eavesdropping, jamming, and hijacking of satellite communications; and cyber surveillance. Most of these capabilities are commercially available, many are free, and some are illegal. In our view, the existence of both legal and illegal markets and capabilities results in an environment where SIGINT has been democratized, or available to anyone.(Weinbaum, Berner and McClintock, 2017)
