Which term is used to inquire about signal strength or readability?

• A. Bravo
• B. Greenwich Mean Time
• C. Coordination
• D. Signal check

Answer: (D)

When checking radio communications, you want to know how well the other station is receiving your transmission. Asking for a signal check directly requests information on signal strength and readability, so the responding party can report how clear the transmission is. This lets you decide if you need to adjust your power, switch frequencies, or rephrase and resend. The other options don’t pertain to signal quality: one is just a phonetic code for a letter, another is a time standard, and another relates to planning coordination. So the term used to inquire about signal strength or readability is signal check.
