Simple one-handed operation is the most essential feature of the IC-A24. The well labeled, large keypad provides user friendly operation. The large display shows both letters and numbers and is easy to see, making for fast frequency recognition. The display is backlit, and so is the keypad. The light stays on until you turn it off – a very handy feature for flying at night. The IC-A24 stores the last 10 channels used. You can easily recall those channels by pushing the “flip-flop” recall buttons on the front panel. It is convenient for switching between several channels, such as NAV and COM channels.
