🔍 Key Concepts

• FCC commercial radio operator licenses and what each authorizes you to do • Difference between operating a radio and making technical adjustments that affect transmitter performance • Which licenses are considered higher class or more technical (telegraph, general radiotelephone, GMDSS, etc.)

💭 Think About

• Ask yourself: does this question ask about simply USING the radio, or CHANGING how the transmitter itself operates (power, frequency, modulation)? • Which of these licenses involves enough technical knowledge and authority to safely adjust a transmitter without causing interference or operating out of spec? • Think about whether power limits (like under 100 watts) change who may work on the equipment, or if the rule is about the nature of the license itself.

✅ Before You Answer

• Identify which licenses in the choices are purely operator-use licenses versus those that indicate technical competence with transmitters. • Confirm whether a restricted radiotelephone permit authorizes transmitter adjustments or just basic operation. • Check which option clearly matches the idea of someone qualified to make adjustments that could affect emissions or cause interference.
