Richard, I was not talking about decoding it, as that would need our understanding of their way of thinking. But detecting fairly rapid variations of Amplitude, Frequency, Phase or a combination of either. That would be easy with the FFT spectrum, and does not need to decode, Just find that there are variable patterns, which would imply messages.
