There is none. Although some people may object if you start transmitting
your alpha, beta and gamma electro-magnetic waves at them.

Sorry. I meant ask what the audio limit would be. In PCM, for example,
the highest permissble frequency is half the sample rate.

What is the highest permissble sound frequency in terms of its carrier
wave in AM radio?
