What type of identification is used when identifying a station on the air as Race Headquarters?

1. Tactical call sign

2. Standard call sign

3. Event name

4. Common identification

The correct answer is: Tactical call sign

When identifying a station on the air as Race Headquarters, a tactical call sign is utilized. Tactical call signs are specifically used to convey the function or role of a station during an event or operation, rather than adhering to the standardized format of amateur call signs. In the context of race events or public service functions, these call signs help communicate the specific purpose or identity of the station in a concise manner. Using a tactical call sign allows for easier recognition among participants and in communication channels, which is especially important in dynamic and potentially chaotic situations like races. It distinguishes the role of the station from regular communications, making it clear that the station is serving a specific event. Other identification types, such as standard call signs and event names, may not provide the same clarity or immediate understanding of the station's function in a temporary or event-specific context. Common identification is not a standardized term used in this context and does not specifically address the role of the station. Thus, the use of a tactical call sign is appropriate and effective in this scenario.
