А Useful Hobby

Dave is fond of listening to the short-wave bands оп his radio. Не likes looking for interesting foreign radio stations.

Dave wrote down the details then called the police and gave them the information. The police informed the Navy and they sent а ship to save the man. The man wanted to reward Dave for helping him.
