Claims

[Claims for Utility Model Registration] A radio receiver in which receivable channels in a reception frequency region can be preset, and a channel in which the reception frequency region can be swept by a preset key, a channel selection key, and the operation of the preset key. a controller; a tuning controller that generates a sweep stop signal when the received electric field strength during the sweep exceeds a predetermined strength; and a tuning controller that displays the received frequency and received electric field strength by generating the sweep stop signal. a memory for storing data; a memory for reading data from the memory; and using the data, simultaneously displaying the received field strength of y receivable channels and the number of receivable channels for each predetermined frequency division in the receiving frequency region; a display device, and the channel controller causes the memory to start the sweeping again after storing the data, and stores the data in an address of the memory corresponding to the operation in accordance with the operation of the channel selection key. read out the data that was
A radio receiver characterized in that the radio receiver is configured to be able to select a desired channel whose reception field strength is displayed by the display device of the reception frequency represented by the data.
