Code generation means for selectively generating a calling code signal that is a combination of a plurality of low frequency signals, and a signal from a transmitting device that emits a radio frequency signal modulated with the calling code signal. Accordingly, the direction in which the radio buoy exists can be measured at the same time as the calling operation by means of storing the transmission frequency of the selective calling radio buoy that is selectively called and emits a response radio wave in correspondence with the calling code. direction finder. 2 A channel number storing the response frequency and a calling code of a selective calling radio buoy and a data output circuit for sending out the calling code are provided, and the data output circuit is transmitted to a selective calling device that generates the calling code to selectively control the calling code. , a direction finder that measures the direction of a radio buoy at the same time as the calling operation.
