たことを特徴とするラジオ受信機。 FM having a frequency characteristic adjustment circuit or level adjustment circuit connected to the line where both AM and FM detection outputs are output, and a forced monaural terminal.
Equipped with a demodulation circuit and a band switching switch,
At the time of reception and FM monaural reception, by supplying a prescribed voltage to the forced monaural terminal, the F
While setting the M demodulation circuit to monaural state,
At the time of reception, one end of the frequency characteristic adjustment circuit or level adjustment circuit is grounded via a band switching switch to set the frequency characteristic adjustment circuit or level adjustment circuit to the operating state, thereby changing the frequency characteristic or level of the AM detection output. and when receiving FM stereo, the predetermined voltage supplied to the forced monaural terminal is bypassed via the band selection switch, thereby setting the FM demodulation circuit to a stereo state. radio receiver.
