If interference is detected, which action is recommended?

• A. Check power levels and battery, switch to a new channel, and if needed try an alternate channel.
• B. Increase power, shout louder, and stay on the same channel.
• C. Rely on other communications channels only.
• D. Wait for interference to end spontaneously.

Answer: (A)

Interference disrupts readability, so the goal is to restore clear communication by checking the radio’s own condition and then moving away from the noisy frequency. Start by verifying power levels and battery—weak power or a dying battery can distort signals and mimic interference. If the gear is healthy, switch to a new channel that’s clear, and if available, try an alternate channel per the incident’s communications plan. This keeps transmissions reliable without fighting the signal on a crowded or noisy frequency. Raising power isn’t helpful and can create more interference or violate operating procedures. Shouting louder isn’t an effective radio discipline and won’t improve clarity. Relying on other channels only or waiting for interference to end spontaneously can jeopardize safety and delay critical information.
