I am writing a story that is set in the future. I love dramatic scenes where important things are said over a radio headset. But I am curious about this. How do you write someone talking over a headset to the main character? For example: MC: "Hey, what's your ETA? We're getting our asses kicked!" Pilot: "You gotta hold out for 1o more minutes." In the example the pilot is talking over the radio. The reason I ask, is because in a show or movie, there would be times where the person on the radio would initiate dialogue. Is there anyway I can write their words so that the reader instantly knows that what's being said is coming in over the headset?
