Maybe ham and short wave radios are the same thing. I don't know.Anyway, it's not the Father Knows Best episode where Bud and his whole family hear a distress call and then call the Coast Guard, but another show where there's some kind of emergency and several kids pass a message around the world to get someone help.I'm pretty sure it was a TV show and not a movie, but I'm not sure. I tried Googling it, but I didn't find the answer. Does anyone know what I'm thinking of?
