Deep Dive: T1F03
The correct answer is D: At least every 10 minutes during and at the end of a communication. According to FCC Part 97.119(a), you must transmit your assigned call sign at least every 10 minutes during a communication and at the end of the communication. This ensures proper station identification throughout your operation. This requirement applies to all communications, whether they're brief contacts or longer conversations. For short communications (under 10 minutes), you identify at the end. For longer communications, you identify at least every 10 minutes and definitely at the end. This regular identification maintains accountability and allows monitoring stations to identify who's operating.
Why Other Answers Are Wrong
Option A: Incorrect. You don't need to identify at the beginning of each contact. Identification is required every 10 minutes during and at the end. Option B: Incorrect. You don't need to identify in every transmission. Identification is required every 10 minutes during communications and at the end. Option C: Incorrect. The requirement is every 10 minutes, not every 15 minutes.
Exam Tip
Call sign ID = Every 10 minutes + end. Remember: Identify at least every 10 minutes during communications and always at the end. For short contacts, identify at the end is sufficient.
Memory Aid
**I**dentify = **I**nterval **T**en + **E**nd (think 'I = ITE' = Interval Ten + End)
Real-World Example
You're having a 25-minute conversation with another operator. You identify with your call sign KA1ABC at the 10-minute mark, again at the 20-minute mark, and finally at the end of the communication. This meets the requirement of identifying at least every 10 minutes during and at the end of the communication.
