とにある。In such a radio transmitter / receiver, when one station arbitrarily sets or changes a channel for transmission, the partner station searches for this channel and receives it. The problem is that it is extremely difficult. In addition, even if you have decided a channel in advance, when that channel is being used by other correspondents,
There is a problem that communication is not possible until the channel becomes free. An object of the present invention is to provide a wireless transmission / reception device that can easily perform communication using any channel.

One station selects the call signal of the partner station from the call signal generator 5 and transmits it from the multi-channel transmitter 1 on a vacant channel. On the other hand, the partner station scans all channels with the scanning receiver 2 and causes the ringing signal detector 6 to detect the received signal each time. When the detected signal is not the calling signal of the own station, scanning is continued, and when the calling signal for the own station is detected, the scanning signal of the scanning receiver 2 is scanned by the channel by the detection signal from the calling signal detector 6. To stop. As a result, the partner station becomes ready to receive the signal from one station, and the channel of the transmitter 1 is switched accordingly, and subsequent mutual communication becomes possible.
