As a boy, I loved to watch Father Knows Best, a TV program showcasing your typical sitcom family of the 50s. One of the more memorable episodes involves a short-wave radio that teenager Bud is refurbishing. When he finally gets the contraption working, he finds himself listening to a conversation between two boats located over a thousand miles away. The signal is bouncing off the ionosphere—making him privy to a conversation between the “Betty Anne,” a 34-foot cabin cruiser and other vessels nearby.
