And now, my 2 cents' worth:

>>I believe that Matthew's concern is not that we might find a signal
we couldn't make any sense out of, but rather, that we might fail to
detect the presence of the signal in the first place, because of it
being so different from what we're looking for.>>

That is exactly what I meant. I read in the book "Contact" that Hadden
said that pm doesn't mess up the spectrum a lot and requires a phase
correlator. If it is leakage, it might appear to be a fluke.

I also had a strange idea. Is it possible for another civilization to
move just perfectly so there is no apparent doppler shift. This might
make a candidate signal look terrestrial. I am not to familiar about the
way planets revolve and rotate, and I figured, if it works this way, then
why not the other? Please tell me if I'm way off on this.
