Abstract

PURPOSE:To extend the reception frequency data of a preset channel selection easily, by storing the reception frequency data of extension in other storage circuit and making control so that the reception frequency data and the display data are allowed to coincide. CONSTITUTION:When a preset channel designation signal corresponds to the reception frequency data of a storage circuit 20, a control circuit 21 reads out the reception frequency data corresponding to the preset channel designation signal from the storage circuit 20 to produce the frequency dividing ratio control data and the reception frequency display data based on it for the reception of broadcast. In this case, other channel designation button is operated and when the preset channel designation signal at that time corresponds to the reception frequency data of the storage circuit 31, the comparison circuit 30 outputs the difference between the reception frequency data from the storage circuit 31 and the display data outputted before from the control circuit 21, to control the reception frequency.
