Pretty much everything that can be said about the signal (no one can call it a message because, as you say, a message has content) can be found here. It's a really fascinating set of pages. Basically, it was an impulse that rose in intensity, then fell. The Big Ear telescope had two antennae that scoured the skies as the Earth rotated. By the time the second antenna was looking at the same patch of sky (three minutes later), there was nothing there.
