An automated transceiver is adapted to monitor a frequency of interest. In response to receiving some predetermined protocol, it becomes activated and records the next transmission on the frequency. The transceiver then rebroadcasts the recorded transmission. In this way, a radio operator can be assured that the transceiver is operating when the rebroadcasted transmission is received. If the transmission from the device is an acceptable quality, there is an assurance that the transceiver is operating properly since, to receive the rebroadcasted transmission, both the transmitter portion must operate to transmit the message to the inventive radio check device, and the receiver portion of the transmitter must be operational to receive the rebroadcasted message from the system. The remote operator need not rely on the subjective determination of another. Further, the participation of another person is not required.
