The Air War of the Information Age continues.

Short Wave frequencies, forgotten but not abandoned, seem filled with clandestine coded content. An intelligence failure of that code results from the very fact that it can be heard by the curious. True spread spectrum with code division would be undetectable. If digital code can be broadcast undetectable, how hard can it be to share frequencies as common property? The analog heads seem hung up on narrow spectrum, property rights and a strong carrier wave. Just the opposite, however, low power, huge freely shared spectrum, coded in interference free clouds, would serve far better. The numbers are coming! May digital prevail. Wired Magazine’s article on numbers stations.

Cognitive or adaptive radio promises some of the same ability to share spectrum. CR may allow a migration between the old and the new. CR has the ability to adapt in a transition from the obsolete concept of spectrum allocation and FCC regulation to a shared reality of space and the transparency of light. FCC should limit itself to monitoring and policing dysfunctional radio technologies that hog and destroy with noxious noise and allow the new quantum technology of information to spread freely in a commons.

In an ideal world, there should be no discernable difference between free speech and free information through space.
