Just to play devil's advocate for a minute, wouldn't that make the frequency basically the crypto key that would need to be protected? If a potential attacker knew the frequency, he could broadcast a low-entropy signal on it, causing your previously-random seeds to become nonrandom and ruining your crypto.
