[Cryptography] Hacking spread spectrum clocking of HW ?

Traditional spread spectrum seem rather off the shelf
and wouldn't really consider encrypted as such.
What I mentioned *is* encrypted, both at the RF
layer itself, and at the data layer riding on top.
It's also really hard to locate random background
noise (power). Even if, since random noise can't be
proven to be crypto, it can't be shut down due to
any crypto reason, insufficient cause.

Nor do guerrilla radios care about such laws.

The history of any such takeovers, classified or otherwise,
would be interesting read.
