When preparing to transmit, which of the following is a barrier to transmitting?

• A. Tone and body language
• B. Proactive listening
• C. Clear audio level
• D. Frequent confirmations

Answer: (A)

Nonverbal cues can block effective transmission because they shape how your message is delivered and received. Tone signals confidence, urgency, or calm; if it’s rushed, too soft, or tinted with hesitation, the listener may misinterpret intent, miss parts of the message, or feel the need to request repetition. Body language affects your own readiness and how you formulate and pace what you say—even though the radio won’t relay your gestures, the way you prepare and verbally express yourself is influenced by it. In demanding environments, this can introduce uncertainty right as you begin transmitting. In contrast, actively listening to others, keeping a clear, audible voice, and regularly confirming understanding all support accurate and efficient communication, reducing the chance of miscommunication during transmission.
