"It's not exactly code. All you need to do is record it and slow it down. They're not broadcasting at us. If a star has planets, inhabited planets, and there is broadcasting between them, they would send it on a tight beam to save power." He looked for comprehension. "You know, like a spotlight. Theoretically, a tight beam can go on forever without losing power. But aiming would be difficult from planet to planet. You can't expect a beam to stay on target, over such distances, more than a few seconds at a time. So they'd naturally compress each message into a short half-second or one-second-length package and send it a few hundred times in one long blast to make sure it is picked up during the instant the beam swings across the target." He was talking slowly and carefully, remembering that this explanation was for the newspapers. "When a stray beam swings through our section of space, there's a sharp peak in noise level from that direction. The beams are swinging to follow their own planets at home, and the distance between there and here exaggerates the speed of swing tremendously, so we wouldn't pick up more than a bip as it passes." "How do you account for the number of squawks coming in?" the _Times_ asked. "Do stellar systems rotate on the plane of the Galaxy?" It was a private question; he spoke impulsively from interest and excitement. The radio decoder grinned, the lines of strain vanishing from his face for a moment. "Maybe we're intercepting everybody's telephone calls, and the whole Galaxy is swarming with races that spend all day yacking at each other over the radio. Maybe the human type is standard model." "It would take something like that," the _Times_ agreed. They smiled at each other. The _News_ asked, "How did you happen to pick up television instead of voices?" "Not by accident," Nathen explained patiently. "I'd recognized a scanning pattern, and I wanted pictures. Pictures are understandable in any language." * * * * * Near the interviewers, a Senator paced back and forth, muttering his memorized speech of welcome and nervously glancing out the wide streaming windows into the gray sleeting rain. Opposite the windows of the long room was a small raised platform flanked by the tall shapes of TV cameras and sound pickups on booms, and darkened floodlights, arranged and ready for the Senator to make his speech of welcome to the aliens and the world. A shabby radio sending set stood beside it without a case to conceal its parts, two cathode television tubes flickering nakedly on one side and the speaker humming on the other. A vertical panel of dials and knobs jutted up before them and a small hand-mike sat ready on the table before the panel. It was connected to a boxlike, expensively cased piece of equipment with "Radio Lab, U.S. Property" stenciled on it.
