"But he isn't using much power," Jack added.
"Afraid some of us'll hear it."

"It's no use. Either he's using some code which I don't know or else it's so faint I've got it all balled up."
"Same here. I couldn't make head or tail out of it."
"Well, we have the satisfaction of knowing that the person or persons he thinks he's sending to isn't making even that much out of it because he isn't hearing it at all," Bob chuckled.
"But, Bob, if he expects to get him with a spark of that size he must think he's pretty near."
"Reckon that's so."
