Question T1F02
From subelement T1 - T1F
How often must you identify with your FCC-assigned call sign when using tactical call signs such as “Race Headquarters”?
Why is this correct?
When using tactical call signs like 'Race Headquarters,' you must still identify with your FCC-assigned call sign at the end of each communication AND every ten minutes during a communication per Part 97.119(a). Tactical calls describe function or location but don't replace your legal identification requirement. Option A is wrong because tactical calls are supplemental, not replacements. Option B's hourly identification is too infrequent. Option D requires identification after every transmission, which exceeds FCC requirements and would be impractical during busy operations.
Memory tip
Remember the '10 and done' pattern: every 10 minutes during communication and at the end. This same timing rule applies whether you're using tactical calls, regular operation, or any other amateur communication. The FCC doesn't change identification intervals based on the type of call signs you're using.

Tactical call signs enhance operational efficiency during events by identifying station function rather than operator identity. However, Part 97 station identification requirements remain unchanged - the FCC requires your assigned call sign for legal station identification regardless of any supplemental tactical designators used. This ensures regulatory compliance while allowing practical operational flexibility during public service events, emergency communications, or coordinated activities where functional identification improves communication clarity and safety.
Think about it
Why do you think the FCC allows tactical call signs but still requires regular call sign identification intervals during their use?
