The fact that CTCSS is used for selective calling of a specific tone frequency of z to 254.1 Hz or activation of a repeater station is described in, for example, CQ hamradio magazine, 1
It is well known as described in the advertisement of the applicant of the present application in the May 983 issue, page 326 of the June 1984 issue of the same publication, and the like.

る。The basic principle of CTCSS is as follows. EIA
One of the tone frequencies established by is set in advance by the transmitting side and the receiving side. The transmitting side superimposes it on the voice signal, modulates it, and then transmits it to the partner station. A CTCSS encoder generates a tone frequency signal on the transmitting side, and a CTCSS decoder detects whether the tone frequency signal received on the receiving side is a predetermined tone frequency signal. That is, the receiving side is provided with a CTCSS decoder for detecting the tone frequency signal transmitted superposed on the voice signal, and the tone signal transmitted from the transmitting side is detected.

And the tone frequency preset on the receiving side match, the mute is released and an audio output is obtained from the receiver. That is, selective calling is performed. If the receiving side is a repeater station, the repeater station is activated and relay operation is performed. If the tone frequencies do not match, the mute remains on and no audio output is obtained. That is, selective calling is not performed. If the receiving side is a repeater station, the repeater station is not activated.

るようにＣＰＵが制御する。The switching means selects a reception signal from the first wireless transmission / reception unit and a reception signal from the second wireless transmission / reception unit. In the switching operation of the switching means, when it is determined that the first wireless transmission / reception unit has a reception signal, the reception signal from the first wireless transmission / reception unit is selected for a predetermined time, and the second wireless transmission unit is selected for the next predetermined time. Switching is performed in time division so as to select the received signal from the transmitter / receiver. This switching operation is controlled by the CPU. The signal selected by the switching means is supplied to the CTCSS decoder. The CTCSS decoder detects a predetermined tone frequency, which is determined in advance with the transmitting side, in the supplied received signal. CT
When the CSS decoder detects a predetermined tone frequency, the CPU controls so that the receiving unit on the side receiving the tone frequency signal outputs the tone frequency signal.

し、ＣＰＵに出力する。ＣＰＵは第１の無線送受信部の
スピーカーから受信音を出力するように制御する。Now, it is assumed that the first wireless transmission / reception unit and the second wireless transmission / reception unit receive the same predetermined tone frequency. Then, it is assumed that the switching unit selects the reception signal from the first wireless transmission / reception unit at a predetermined time that is switched in time division. Since the tone frequency is superimposed on the selected reception signal, the CTCSS decoder detects the tone frequency signal and outputs it to the CPU. The CPU controls to output a reception sound from the speaker of the first wireless transmission / reception unit.

の動作を順次繰り返す。The switching unit selects the reception signal from the second wireless transmission / reception unit at the next predetermined time when the switching is performed by time division. Since the tone frequency is superimposed on the selected reception signal, the CTCSS decoder detects the tone frequency signal and outputs it to the CPU. The CPU controls the speaker of the second wireless transmission / reception unit to output a reception sound. The above operation is sequentially repeated.

する。If the predetermined tone frequency signal is not superimposed on the received signal of either the first wireless transmission / reception unit or the second wireless transmission / reception unit, the CTCSS decoder cannot detect the tone frequency signal. Therefore, the CPU controls so that the received sound is not output from the speaker of the wireless transmission / reception unit on which the predetermined tone frequency signal has not been detected.
