Abstract
An interface device for connection between a facsimile reproduction machine and a simplex radio includes a receiving circuit and a transmitting circuit. A switch connects an appropriate one of the circuits to the machine. A control circuit monitors the change in the mode of operation of the machine and operates upon the switch to cause a corresponding change of connection to the machine. The control circuit also operates upon the transceiver to condition it to a transmit mode upon the transmit circuit being selected.
