Abstract: An automated direction finder system for providing verbal bearing information for aircraft is disclosed. The system extracts data regarding the bearing of an aircraft from the radio transmission requesting the bearing and then utilizes the extracted data to control the gating between a storage drum having recorded therein a full range of possible bearings and an amplifier which amplifies the appropriate bearing of the aircraft and transmits the same back to the aircraft.
