Abstract
A radio receiver electronic tuning system includes a frequency sweep circuit for changing received frequencies by sequentially changing received frequency designating information, and a broadcasting wave search circuit for generating a search stop signal when receiving a broadcasting wave having a received electric field intensity higher than a certain level during the frequency sweep. The receiver further includes a preset channel selecting circuit for reading out the received frequency designating information prestored in a preset memory in an area corresponding to a channel selection key at the time of the operation thereof, thereby permitting direct channel selection. When an auto-preset key is actuated, the frequency sweep circuit is activated to sequentially change the received frequencies. When the search stop signal is generated during the sequential changing of the received frequencies, the received frequency designating information is stored in the preset memory.
