自動同調記憶受信機。[Claim for Utility Model Registration] Sweeping broadcast waves using a PLL frequency synthesizer, sequentially storing frequency information related to the frequency of broadcast waves automatically tuned by such sweeping, and presetting this stored frequency information. in which the desired broadcast radio waves can be received by receiving the frequency information of the broadcast radio waves, the first radio field intensity information of the broadcast radio waves at a first reception sensitivity, and the second reception lower than the first reception sensitivity. a storage means for storing a predetermined number of second radio wave intensity information of the said broadcast radio waves at the sensitivity; the first radio field strength information at the reception sensitivity, the second radio field strength information at the second reception sensitivity, and the first radio field strength information already stored in the storage means.
and second radio field intensity information sequentially until the end of the sweep, and by comparing the comparison means, new radio field intensity information automatically tuned from the first and second radio field intensity information already stored in the storage means is obtained. At the time when it is determined that the first and second radio field strength information of the broadcast radio waves are stronger, the frequency information of the new broadcast radio wave and the first and second radio field strength information are stored in the storage means. An automatic tuning memory receiver comprising a memory control means for exchanging frequency information of broadcast radio waves and first and second radio field intensity information.
