Which of the following is an example of remote control as defined in Part 97?

The concept of remote control as outlined in Part 97 of the FCC rules refers specifically to the ability to control a station or another device from a distance using radio equipment. Among the options provided, controlling a model aircraft, boat, or car by amateur radio fits this definition perfectly. This activity involves using amateur radio frequencies to send commands to the device over a distance, showcasing a practical application of radio communication in a remote-controlled setting.

While repeater operation and operating a station over the internet involve communication and control elements, they do not strictly fall under the traditional definition of remote control in the context of Part 97. Repeaters facilitate local communications and are not inherently remote control operations. Similarly, operating a station over the internet does not utilize amateur radio frequencies for control but rather utilizes internet protocols, which is outside the scope of the definition for remote control in this regulatory context. Therefore, controlling a model aircraft, boat, or car directly aligns with the intended definition used in these regulations, making it the appropriate example of remote control within the specified framework.
