- List consumer devices and services that use analog or digital radio communications.
- Explain how NOAA Weather Radio (NWR) can alert you to danger.
- Explain how RFID works and what are some of its uses in everyday life.
- Radio Regulation. Discuss the following with your counselor:
- What the Federal Communications Commission (FCC) does and how it is different from the International Telecommunication Union (ITU).
- How radio station call signs are used in broadcast radio and amateur radio.
- How the phonetic alphabet is used to communicate clearly.
