Deep Dive: T1F02
The correct answer is C: At the end of each communication and every ten minutes during a communication. According to FCC Part 97.119(a), when using tactical call signs (like 'Race Headquarters' or 'Net Control'), you must still identify with your FCC-assigned call sign at the end of each communication and at least every 10 minutes during longer communications. Tactical call signs are convenient identifiers for specific events or operations, but they don't replace the requirement to identify with your official FCC call sign. The FCC call sign must be used regularly to maintain accountability and allow proper station identification. This ensures that anyone monitoring can identify the actual licensed station, not just the tactical identifier.
Why Other Answers Are Wrong
Option A: Incorrect. Tactical call signs are not sufficient. You must identify with your FCC call sign regularly. Option B: Incorrect. Identification is required more frequently than once per hour. It's required at the end of each communication and every 10 minutes during communications. Option D: Incorrect. You don't need to identify at the end of every transmission. Identification is required at the end of each communication and every 10 minutes during communications.
Exam Tip
Tactical calls = Still need FCC call sign. Remember: When using tactical call signs, you must still identify with your FCC call sign at the end of each communication and every 10 minutes during longer communications.

Real-World Example
You're participating in a public service event and using the tactical call sign 'Race Headquarters' for convenience. During a 20-minute communication coordinating race operations, you identify with your FCC call sign KA1ABC at the 10-minute mark and again at the end of the communication. The tactical call sign is convenient, but your FCC call sign is required for proper identification.
