Even he hasn’t put his knowledge to practical use, having built only devices that never actually emitted any RF.So what does one talk about when circumspection is the order of the day? As it turns out, quite a lot. Jeremy focused on how the military leverages the power of radio frequency jamming to turn the tables on enemies, and how civilian police forces are fielding electronic countermeasures as well. It’s interesting stuff, and Jeremy proved to be an engaging guide on a whirlwind tour into the world of electronic warfare.

Jeremy comes to this field more as an informed enthusiast than as an employee or contractor for one of the many alphabet agencies or defense contractors who jealously guard such secrets. A recent EE grad from Wright State University, where courses on electronic warfare (EW) are offered, Jeremy not only developed an interest in the field but has been able to observe some of the systems in action, thanks to nearby Wright-Patterson Air Force Base.
After the obligatory “Don’t try this at home” warnings, Jeremy gave a brief history of electronic warfare, stretching back to what was possibly the first electronic war — the…
