Hmm. And if an attacker discovers you're using this method, and decides to send out a signal on the same frequency? You might find your "random" numbers are suddenly all zeros...
Band hop. Build a variable modulo counter and use its output to reset its modulo and hop the band around pseudo-randomly. Unless they know or stumble on the particular design you are using it will be very difficult to track.
An even better idea: disconnect the antenna. Most of the noise comes from the front end amplifier, not the galactic and cosmic background, at least in your average consumer grade receiver. And this is a quantum process that someone else definitely can't predict or copy. Phil
