What is the FCC Part 97 definition of a beacon?
A government transmitter marking the amateur radio band edges
Incorrect, because a beacon is not a government transmitter marking amateur radio band edges; it is specifically an amateur station used for propagation experiments.
A bulletin sent by the FCC to announce a national emergency
Incorrect, as it misinterprets the definition; a bulletin sent by the FCC to announce a national emergency is not a beacon.
A continuous transmission of weather information authorized in the amateur bands by the National Weather Service
Incorrect, because a continuous transmission of weather information authorized in the amateur bands by the National Weather Service does not fit the definition of a beacon; beacons are used for propagation and experimental purposes.
An amateur station transmitting communications for the purposes of observing propagation or related experimental activities
Correct, because it precisely matches the FCC’s definition of a beacon under Part 97.3(a)(9), meaning an amateur station transmitting communications for the purposes of observing propagation or related experimental activities.
Explanation
In the context of amateur radio, the FCC Part 97 regulations define several types of stations and their purposes. Understanding these definitions is crucial for operating within the legal frameworks set by the FCC. The definition of a beacon is specifically outlined in Part 97.3(a)(9). A beacon, according to these regulations, is an amateur station that transmits communications specifically for the purposes of observing propagation or for related experimental activities. This is a vital tool for radio operators as it helps in understanding how radio waves travel through the atmosphere, which can vary based on geographical location, time of day, and solar activity. By using beacons, operators can assess the effectiveness of their equipment and the conditions for sending and receiving signals over various distances.
