What signals readiness to respond on a channel?

• A. You maintain radio silence until asked.
• B. You abandon the channel.
• C. You say your reply or acknowledgment and hold the line.
• D. You send a separate urgent message.

Answer: (C)

Indicating you’re ready to respond on a channel is shown by delivering your reply or acknowledgment and holding the line. When you’ve heard the transmission and you’re prepared to continue, you state your response and keep the line open so the other person can hear you and, if needed, follow up with related traffic. This keeps the circuit active and avoids a break in communication, signaling clearly that you’re engaged and ready for the next step.

Staying silent until asked would slow or stall the conversation, abandoning the channel ends contact, and sending a separate urgent message would disrupt the current exchange and create confusion—the line should be used for your immediate response and acknowledgment.
