A radio receiver includes a first tuner circuit (1) for receiving radio signals of a first and a second frequency range, and a second tuner circuit (2) for receiving radio signals of a third frequency range. The second tuner circuit (2) is also used for receiving the first frequency range and works independently of the first tuner circuit (1), in that the second tuner circuit (2) includes a first mixer circuit (35, 36, 37) which converts the radio signals of the third frequency range to the second frequency range, and a first integrated circuit element (5) which alternatively converts radio signals of the first frequency range to a first intermediate frequency, or the radio signals of the third frequency range converted to the second frequency range by the first mixer circuit (35, 36, 37) to a second intermediate frequency. The second tuner circuit (2) may derive coded information, more particularly, traffic information from the radio signals of the first frequency range.
