“What?”
“Handel’s Largo. The first phonograph record ever broadcast. Sent out by Fessenden from Brant Rock in late 1906. You’ll hear his CQ-CQ any minute now. Bet you a drink.”
“Okay, but what was the dit-dit-dit that started this?”
Mulvaney grinned. “Marconi, George. What was the most powerful signal ever broadcast and by whom and when?”
“Marconi? Dit-dit-dit? Seventy-six years ago?”
“Head of the class. The first transatlantic signal on December 12, 1901. For three hours Marconi’s big station at Poldhu, with two-hundred-foot masts, sent out an intermittent S, dit-dit-dit, while Marconi and two assistants at St. Johns in Newfoundland got a kite-born aerial four hundred feet in the air and finally got the signal. Across the Atlantic, George, with sparks jumping from the big Leyden jars at Poldhu and 20,000-volt juice jumping off the tremendous aerials—”
“Wait a minute, Pete, you’re off the beam. If that was in 1901 and the first broadcast was about 1906 it’ll be five years before the Fessenden stuff gets here on the same route. Even if there’s a seventy-six light-year short cut across space and even if those signals didn’t get so weak en route that we couldn’t hear them—it’s crazy.”
“I told you it was,” Pete said gloomily. “Why, those signals after traveling that far would be so infinitesimal that for practical purposes they wouldn’t exist. Furthermore they’re all over the band on everything from microwave on up and equally strong on each. And, as you point out, we’ve already come almost five years in two hours, which isn’t possible. I told you it was crazy.”
“But—”
“Ssshh. Listen,” said Pete.
