The two are exchanged using the button marked with a double-headed arrow. The tuning control on the right only affects the standby frequency. Airband or aircraft band is the name for a group of frequencies in the VHF radio spectrum allocated to radio communication in civil aviation, sometimes also referred to as VHF, or phonetically as "Victor". Different sections of the band are used for radionavigational aids and air traffic control.
