If my impression is correct, wouldn't that basic, simple, repeated pattern be more indicative of a natural phenomenon? Wouldn't sophisticated communication be more varied? Are we really interested in finding the most boring life in the universe?
I hope my impression is wrong.

I sometimes wonder about for a single signal. However the SETI of today does their search
on a target simultaneously search on about 6 Million (6,000,000) or more wavelengths.
They have built new machines to do this. I am not aware if the processing were to find
on some of those channels might sound like noise as a single frequency yet when put
together could make a bonafide signal by properly piecing it together.
I know that an FFT signal analysis is run on any capture signal on-axis, then off-axis. I
am not clear with simultaneous capture that whether multiple frequencies are correlated
or not.
