"What?" yelled Barney.
"Must you yell?" asked Christine ruefully. "These phones are plenty uncomfortable without some loudmouthed bird screaming."
"Sorry, but a hundred amps... whoosh! What have we got here, anyway?"
"Yeah," said Christine. "I was about to say that my input meter is running wild again."
"Gone?"
"Completely. You shouldn't have hidden it behind that big box. I didn't notice it until just now, but she's completely gone."
"I'll be over. I think we've got something here."

"Nothing brilliant," said Jim. "We could use super-output voice amplifiers and yell halfway across the planet if we didn't have radio. We can radio far better than this cockeyed system of signaling."
