PURPOSE:To set a speech channel to an opponent station repeatedly and automatically even when the speech channel to the opponent channel can not be set by single-time origination, by providing a means which outputs an originating signal repeatedly at preset intervals of time. CONSTITUTION:A control part 2 monitors an origination switch (SW)1 and a repetitive origination switch SW13 and holds a wait state when the switches SW1 and SW13 are both off. For example, a channel (CH) specifying signal for specifying one of 79 speech CHs is outputted to a synthesizer 3 and a local oscillation frequency of frequency corresponding to the CH specifying signal is applied from the synthesizer 3 to a reception part 4. When it is judged that the received speech CH is free, a control signal containing a group number signal read out of a group number memory 8 is set and applied from the synthesizer 3 to a transmission part 9. Thus, this station resets itself to the stand-by state unless the sent control signal arrives at the opponent station, but the speed CH is set when the origination SW13 is pressed. |
