Indeed, I should've mentioned GPS :) Especially since it's a pretty popular field for SDR implementation nowadays! Now, it wouldn't ever lend itself to any relevantly high data rate – Shannon's channel capacity just doesn't allow that. Anyway, grarpamp, what's up with the funny subject line? What's

Imagine noise radiator capable of making your spectrum analyzer look like /dev/urandom across the board. There's no center frequency, no clock, no freq hopping, no spreading, no observables, no off the shelf wireless hardware or reference design... it's not based on that. To any viewer, it's just b
