"Broadcast it?" Rodeo repeats, frowning slightly at the idea of that. He supposes it's the only way that makes sense, though. He doesn't know where Addie is in order to send it directly to her, but maybe there's a chance she'd pick up the broadcast. It's a slim one, but any chance is better than none. He'll have to be careful what the message says, to prevent anyone from understanding and figuring out who he's looking for. It would put both him and Adelaide at risk if anyone did. "Well, how does it work? Does it just go out continuously? You reckon someone might actually pick it up out there?"
