ARRL Technician Practice Exam

Which indicator is required by the FCC to be transmitted after a station call sign?

1. /KT, /AE or /AG when using new license privileges earned by CSCE

2. /M when mobile

3. /P when portable

4. No indicator is required

The correct answer is: /KT, /AE or /AG when using new license privileges earned by CSCE

The correct answer highlights that operators must use specific indicators after their call signs when utilizing new privileges granted through a Certificate of Successful Completion of Examination (CSCE). These indicators, such as /KT, /AE, or /AG, signify the new privileges related to operator classifications. They inform other amateur radio operators of the current status of the station's operator, helping to maintain clarity within communications. When a technician may be operating under new privileges not fully encapsulated by their current call sign, such indicators are essential for compliance with FCC regulations. This enables others to understand the context of transmissions more clearly, especially if the operator has recently earned advanced privileges or licenses. The other choices, while relevant in certain contexts, don't encompass the unique aspect of indicating newly earned privileges from a CSCE. For example, using /M indicates mobile operation, and /P indicates a portable operation; however, these do not address the requirement that arises from new license privileges specifically awarded through CSCE. Thus, the precision that comes with using the correct indicator after the call sign in this context is what makes this particular choice the correct answer.
