５へ送出する。When the other party selects simplex communication, the reception signal S1 does not include a synchronization signal. Therefore, the synchronization detection circuit 71 cannot detect the synchronization signal component and outputs the detection signal S2 indicating that there is no synchronization signal. On the other hand, the carrier detection circuit 72 detects a continuous carrier at a constant level and outputs it as a detection signal S3. Based on these two detection signals, the determination circuit 73 determines that it is simplex communication because there is no synchronization signal and it is a continuous carrier, and outputs a signal S4 indicating simplex communication to the control unit 8. The control unit 8 switches the changeover switch 6 to the contact a side, displays the fact that the simplex communication is performed via the LED 9 and the LCD 10, and at the same time, notifies by voice through the speaker 11. Then, when the press talk switch 12 is pressed, the transmission signal is sent to the modulator 5.

The carrier component is periodically intermittent. Therefore, the synchronization detection circuit 71 outputs the detection signal S2 indicating the presence of the synchronization signal.
On the other hand, the carrier detection circuit 72 detects a carrier component which is intermittent in a fixed cycle and outputs it as a detection signal S3. Based on these two detection signals, the determination circuit 73 determines that it is the one-wave simultaneous transmission / reception communication because it is a carrier that has a synchronization signal and is periodically intermittent, and the control unit 8 outputs the signal S4 indicating the one-wave simultaneous transmission / reception communication. Output to. The control unit 8 switches the changeover switch 6 to the contact b side and, at the same time, the LED 9 and the LCD.
The simultaneous transmission and reception of one wave is displayed via 10 and at the same time, a voice notification is given via the speaker 11. Then, when the call start switch 13 is pressed, the processing of the call signal is started.
