Want to know the hardware behind Echelon?

Want to know the hardware behind Echelon? The other day I posted a book (Chatter) review about NSA. In this follow-up, the equipment used. "Aside from using the system for industrial espionage and bypassing international and national laws to listen in on people, it is also used to listen out for people like Osama bin Laden and assorted terrorists in the hope of preventing attacks."

Impressive and scary at the same time.

Well put.

Postroad - That would be your FPP of yesterday that you're referring to? The one that's still quite available to everyone (and has only 16 comments)? The one where you could have posted the one link in this FPP, as part of a comment, rather than starting a new thread?

OK, I think reflection's post above sums up my feelings. But I'll also point out that if the writer of this one article gets wrong a basic technology fact, then I don't trust the rest of what he says, either.

"A DSP chip turns analogue signals from a sensor or recorder into digital information usable by a computer. Digital cameras will use a DSP to turn the light signals coming through the lens into digital picture element, or pixel, information."

Does he mean an A/D converter? Because that's what turns analog signals into digital info. DSPs are Digital Signal Processors, which, duh, process signals that are already digital.
