Before transmitting by radio, you should do which of the following to avoid interrupting ongoing transmissions?

• A. Listen to ensure the channel is not in use.
• B. Consult the Dispatcher first.
• C. Turn on the loudspeaker.
• D. Transmit on any channel.

Answer: (A)

Not interrupting ongoing transmissions is achieved by checking the channel first, which means listening to be sure it isn’t already in use before you speak. This quick listen lets you hear if someone else is transmitting and wait until the channel is clear, preventing garbled messages and safety-related miscommunication. Consulting the Dispatcher may be necessary for instructions, but it doesn’t substitute for confirming the channel is free. Turning on a loudspeaker or trying to transmit on a different channel won’t prevent interruptions and could cause more confusion. So, the best practice is to listen to ensure the channel is free before transmitting.
