ARRL Technician Practice Exam

Which of the following formats of a self-assigned indicator is acceptable when identifying using a phone transmission?

1. All of these choices are correct

2. /KT, /AE, or /AG

3. /M only

4. /P only

The correct answer is: All of these choices are correct

In amateur radio, self-assigned indicators are used by operators to signify their operating conditions or status while on air. When identifying during a phone transmission, it is important to use acceptable formats that are recognized by the Federal Communications Commission (FCC) and the amateur radio community. The self-assigned indicators, such as "/M" for mobile operation, "/P" for portable operation, "/AE" for advanced extra-class operators, and "/AG" for amateur general, serve to provide additional context to the operator's status. The various formats enhance communication by letting other operators know how and where the identification is taking place. The choice stating "All of these choices are correct" encompasses all the valid self-assigned indicators that improve clarity in transmissions. Therefore, the comprehensive understanding that "/KT," "/AE," "/AG," "/M," and "/P" are all acceptable formats validates that it is correct to identify with any of these notations during phone transmissions. This reflects a broader range of permissible formats, each of which adds a useful layer of information to the operator's identification.
