Amateur radio is useful for:
1. Having fun talking to other hams around the world, or simply in your own town.
2. Keeping emotionally healthy. (Astronauts, most of whom are hams, talking to us hams on the ground.)
3. Passing emergency traffic across the land.
4. Providing communications between soldiers, sailors, and fliers from where they are stationed to back home.
5. Developing new equipment, concepts, methods, and modes of communications. Many of the radio technology today is founded in work done by hams.
6. Providing emergency communications service for disasters and other local disasters.
7. Providing for long-distance ham-to-ham communications by building, launching, and maintaining a number of Earth-orbiting satellites, like OSCAR (Orbiting Satellite Carrying Amateur Radio) and AMSAT.
