We were watching Father Knows Best (yes we are Medicare eligible) and the episode had Bud and Jin listening to marine traffic and a ship was not aware of a storm and got in trouble. The boat could not hear or contact the Coast Guard, but the Andersons did. The boat was 1,000 miles away and Bud explained that they were hearing it because of skip. They realized that they should make a long distance call ( remember those?) to the Coast Guard, and the boat was saved. Also, My Three Sons had George Takei (of Star Trek fame) as a ham radio operator. Any others?
