Several reports from the Department of Defense’s Joint Spectrum Center were originally published in April 2010 by a small blog called DoD Leaks. The blog published less than a dozen documents over a two month span and then ceased all activity. The blog’s description states that it was created in response to Cryptome’s call for more publication of “for official use only” documents that are available in the public sphere. These documents relate to frequency allocation and electromagnetic interference tests conducted in relation to datalinks used by Predator drones.
