２つの機能を併用しても大きくすることはない。 During a call, the frequency-modulated voice is demodulated by the discriminator 1, one side of the demodulated voice is input to the amplifier 2, the other side is amplified by the noise amplifier 4, and the demodulated voice is amplified by the detector 5. Upon detection, the gate circuit 6 is opened, and the amplifier 2 is connected, and a sound is emitted from the speaker 3. However, when another group is talking, the continuous tone signal of the other group passes through the filter 7 and is detected by the detector 8, which closes the gate circuit 9, disconnects the amplifier 2, and outputs the signal from the speaker 3.
I try not to make any more noise. At this time, the lamp drive circuit 10 is activated by the output of the detector 8, causing the light emitting diode 11 to emit light, indicating that the other group is talking. If you feel suspicious because the light emitting diode 11 is emitting light for a long time, turn the switch SW.
When it is closed, the gate circuit 9 is forcibly opened and the amplifier 2 is forcibly connected, so that it can be confirmed that other groups are talking. Therefore, under normal circumstances, you can tell that another group is talking just by looking at the light emitting diode 11, and if you feel suspicious, you can operate the switch SW to confirm that a call is in progress, saving you time and effort. You can definitely check if other groups are talking. Recently, a push button switch with a light emitting diode as shown in FIG. 2 has been developed. This is done by attaching the terminal 15 to the printed board, and the light emitting diode 14
This push button switch with a light emitting diode is used for the switch SW light emitting diode 11 in the circuit shown in Figure 1. Then, the size of the mobile radio will not increase even if the two functions are used together.

If a push button switch with a light emitting diode is used, the above effect can be achieved without the need to increase the size.
