Claims

[Scope of utility model registration request]

A radio receiver in which receivable channels in a reception frequency region can be preset includes a preset key, a channel selection key, a channel controller that causes the reception frequency region to be swept by operating the preset key, and a reception electric field during the sweeping. A tuning controller that generates a sweep stop signal when the intensity exceeds a predetermined intensity, a memory that stores data representing a reception frequency and a reception electric field strength upon generation of the sweep stop signal, and a memory that stores data representing the reception frequency and reception electric field strength. and a display device that reads the data and simultaneously displays the reception field strength of the receivable channels for each predetermined division of the reception frequency region, and the channel controller reads the data again after the memory stores the data. starting the sweep, and reading out the data stored in the address of the memory corresponding to the operation with the operation of the channel selection key, and displaying the received electric field strength on the display device of the reception frequency represented by the data; A radio receiver characterized in that it is configured to be able to select a desired channel.
