Which of the following self-assigned indicators are acceptable when using a phone transmission?

Deep Dive: T1F06

The correct answer is D: All these choices are correct. According to FCC Part 97.119(c), when using self-assigned indicators (like portable, mobile, or location indicators), you may use various terms to separate them from your call sign, including stroke, slant, or slash. All three terms refer to the same separator character (/). These terms are all acceptable ways to indicate a self-assigned indicator. For example, 'KL7CC/W3' (using stroke, slant, or slash) indicates that station KL7CC is operating portable in the 3rd call area. The separator character can be referred to by any of these names, and all are acceptable in amateur radio practice.

Why Other Answers Are Wrong

This question has no incorrect options since all choices are correct. However, it's important to understand that stroke, slant, and slash all refer to the same separator character (/) and are all acceptable terms.

Exam Tip

Self-assigned indicators = Stroke/slant/slash all OK. Remember: All three terms (stroke, slant, slash) refer to the same separator character and are all acceptable when using self-assigned indicators.

Memory Aid

**S**elf-**A**ssigned = **S**troke/**S**lant/**S**lash **A**ll (think 'SA = SSSA' = Stroke/Slant/Slash All)

Real-World Example

You're operating portable from a different call area. You identify as 'KL7CC/W3' using a slash (/) to separate your call sign from the portable indicator. Whether you call it a stroke, slant, or slash, it's the same character and all three terms are acceptable. This clearly indicates you're operating portable in the 3rd call area.
