摘要
PURPOSE: A device for automatically tracking the propagation of a car radio is provided to enable a driver to continuously track the frequency of a radio program which the driver listens to, so that the driver can normally listen to the program while being out of a specific area, thereby improving user's convenience. CONSTITUTION: An antenna(21) receives a propagation in accordance with a radio program. A propagation tracking unit(22) determines and changes the frequency of the propagation. An amplifier(23) amplifies the received propagation, and outputs the amplified propagation. A microcomputer(25) tracks the corresponding propagation when a car moves to other area, and decides whether the tracked propagation corresponds to the radio program. A memory(26) stores the frequency of the radio program by area.
