Ｍ−ＡＭラジオ受信機であって、ＦＭ受信時個受信用バ
ーアンテナのコイルをＦＭ受信回路へ接続する手段を設
けたことを特徴とするＦＭ−ＡＭラジオ受信機。The low frequency signal from the low frequency amplification stage is configured to be supplied to a first terminal of a headphone (or earphone) jack via a first high frequency signal blocking coil, and between the second terminal of the jack and ground. A second high-frequency signal blocking coil is provided in the FM high-frequency signal blocking coil, and the FM high-frequency receiving input signal induced in the lead wire of the headphones (or earphones) during FM reception is transmitted from one of the terminals of the jack via a low-frequency signal blocking capacitor. The F is applied to the FM high frequency input stage.
What is claimed is: 1. An FM-AM radio receiver, characterized in that it is provided with means for connecting a coil of an individual receiving bar antenna to an FM receiving circuit during FM reception.
