Question T1F03
From subelement T1 - T1F
When are you required to transmit your assigned call sign?
Why is this correct?
FCC rules require station identification at least every 10 minutes during communication AND at the end of each communication. Option D correctly states both requirements. Option A incorrectly adds a beginning-of-contact requirement that doesn't exist. Option B would require identification with every single transmission, which is excessive and not required. Option C uses the wrong time interval (15 minutes instead of 10).
Memory tip
Remember the simple phrase 'Ten and End' - identify every ten minutes and at the end. The FCC doesn't micromanage when within those 10 minutes you identify, giving operators flexibility in timing while ensuring regular identification for monitoring purposes.

Station identification serves two critical purposes in amateur radio operations: it enables FCC enforcement monitoring and helps other operators know who they're communicating with. Part 97.119(a) establishes these timing requirements to balance regulatory oversight with operational practicality. During emergency communications or public service events, proper identification becomes even more crucial for coordination and accountability.
Think about it
Why do you think the FCC chose 10 minutes as the identification interval rather than requiring identification with every transmission or extending it to 15 or 20 minutes?
