Question T1F06
From subelement T1 - T1F
Which of the following self-assigned indicators are acceptable when using a phone transmission?
Why is this correct?
All three options are correct because Part 97 allows multiple ways to verbally indicate the slash (/) symbol when adding self-assigned indicators to your call sign. Whether you say 'stroke,' 'slant,' or 'slash,' each clearly conveys the separator between your call sign and indicator. The FCC doesn't specify one required pronunciation, so all are acceptable as long as the meaning is clear to other operators.
Memory tip
When multiple choice answers all describe acceptable variations of the same concept, look for 'All these choices are correct.' The key insight: regulations often allow flexibility in implementation as long as the purpose is achieved—here, clearly communicating your call sign with an indicator.

Self-assigned indicators like '/mobile,' '/portable,' or '/3' (for third district) help other operators understand your operating situation or location. These indicators follow your call sign after a slash separator. In phone operations, you have flexibility in how you pronounce this slash—stroke, slant, or slash all work. This flexibility reflects amateur radio's practical approach: clear communication matters more than rigid pronunciation rules. The indicator system helps with emergency coordination, contest logging, and general courtesy by providing context about your station setup.
Think about it
Why do you think the FCC allows multiple ways to pronounce the slash separator rather than requiring one specific pronunciation?
