Title image for the Aeronautical Radio Operator Certificate unit. A generic handheld VHF radio stands in the foreground of a small aerodrome with a runway, hangar and windsock. A light aircraft passes low across the field and calls: grey waves arrive at the radio and the word Listen appears. Then the push-to-talk button is pressed, blue waves go out from the radio and the word Transmit appears. A drone hovers calmly nearby. Decorative title artwork.
