The Federal Communications Commission (FCC) regulates and manages the airwaves in the United States. For amateur radio, it sets the rules, issues licenses, assigns frequencies, and enforces regulations to ensure operators use the spectrum safely and without interference. There are three levels of amateur radio licenses, and each one builds on the last. The first license gets you on the air and covers the basics. The second adds more knowledge, skills, and privileges, letting you communicate farther and in more ways. The third gives you complete access to all amateur frequencies and the highest operating privileges. Each step takes you deeper into the hobby and opens more opportunities to explore and connect.
