Which proword indicates good line quality during a radio check?

• A. Difficult
• B. Nothing heard
• C. Ok
• D. Clear

Answer: (C)

In a radio check, you use short prowords to quickly communicate how well a signal was received. The proword that directly tells the other station the line quality was good is “OK.” It conveys that the transmission was heard clearly and understood, without ambiguity, and it’s concise for fast, reliable feedback in the field.

Difficult would indicate poor reception, Nothing heard means the signal wasn’t received at all, and Clear can suggest the channel is free of interference but doesn’t explicitly confirm that the received signal was of good readability.
