Abstract: PURPOSE:To reduce the automatic preset time by replacing a high level into a low level and storing the result to a memory when a reception level of a frequency is higher than the level after storage of a preset memory while a search stop signal is generated during sweeping of a reception frequency. CONSTITUTION:A microcomputer system 3 searches automatically a broadcast frequency by the operation of a start key PRE for automatic preset, a signal level S from an intermediate frequency stage IF is subjected to A/D conversion 35, and its output is inputted to a microprocessor MPU30.
