He scours the airwaves again and more intermittent beeps resurface.

“That’s a station in Japan,” he said. “How about that, huh?”

Crovelli and his teammate, George Demontrond, are one of 59 teams in the seventh World Radiosport Team Championship — think Olympics, but with Morse code as a second universal language.
