What method of call sign identification is required for a station transmitting phone signals?
The correct answer is B: Send the call sign using a CW or phone emission. According to FCC Part 97.119(b), when transmitting phone signals, you may identify your station using either CW (Morse code) or phone (voice) emission. Both methods are acceptable for identification on phone bands.
This flexibility allows operators to choose the identification method that works best for their situation. Some operators prefer to identify with Morse code even on phone bands, which can be more reliable in noisy conditions. Others use voice identification, which is more natural for phone operations. The key requirement is that identification must be in English and must occur regularly (every 10 minutes during communications and at the end).
Exam Tip
Phone ID = CW or phone emission. Remember: On phone bands, you can identify using either CW (Morse code) or phone (voice). Both are acceptable methods.
Memory Aid
"**P**hone **I**D = **P**hone or **C**W (think 'PI = PC' = Phone or CW)"
Real-World Application
You're operating on a 2-meter FM repeater using voice. When you identify your station, you can say 'Kilo Alpha One Bravo Charlie' using voice, or you can send 'KA1BC' in Morse code. Both methods are acceptable for identification on phone bands. Some operators prefer CW identification because it's shorter and can be more reliable in noisy conditions.

Why Other Options Are Wrong
Option A: Incorrect. There's no requirement to use the indicator 'RPT' after your call sign. This is not a standard identification format.
Option C: Incorrect. There's no requirement to use the indicator 'R' after your call sign. This is not a standard identification format.
Option D: Incorrect. Phone emission is not the only acceptable method. CW (Morse code) identification is also acceptable on phone bands.
