Well, OK, since you insist on pushing this.

ieeexplore.ieee.org

A single chip spread spectrum device. Spread spectrum, for practical purposes, IS scrambling (encryption is the correct technical term). The RF energy is spread in small chunks over a wide band of the RF spectrum. I thought of spread spectrum because one site suggested that someone go into the next debate with a wideband radio receiver that would cover the band used by that previous in-ear receiver and they should detect it, call the press, and nail Bush. Except if it's spread spectrum, that won't work. The energy is spread out so much that their energy meter will just bounce about the little bit it would due to random RF noise. A random sequence is used to determine what frequency band to use next, so effectively spread spectrum IS encryption.

Now that sort of in-ear receiver, as far as I can determine, is not commercially available. But do you doubt the President could have one made if he wished? If you don't know it, the answer is "Yes".

So that blows the "wires" theory.
