And what if I will use FM receiver, tuned on some channel where is the noise.
If the potentional attacker don't know the what channel was tuned, he is not
able to reproduce this IMHO. Of course, maybe it is possible to record the whole
spectrum to tapes, but I think that the noise will change when recorded and
played back from tape.
