ABSTRACT:
An electronic tuning type radio receiver which is designed so that the received electric field intensity distribution in a received frequency band can be known at a glance. When predetermined key information is applied, receiving frequency designating information for determining the broadcasting station to be received is sequentially changed to detect the received electric field intensity of each received frequency. A received frequency vs electric field intensity distribution is produced based on the detected value and the corresponding received frequency and is displayed on a CRT display or the like.
