PURPOSE:To unify operations of a host machine and a transverter to facilitate handling them, by displaying the frequency of a transverter on the host machine to activate the transverter of this frequency band when the host machine selects the operating state of the transverter. CONSTITUTION:When a transceiver as a host machine 1 is operated in the frequency band inherent to the host machine 1, a transverter 10 is in the quiescent state; and when the host machine 1 selects the operating band of the transverter 10, the frequency display on the host machine 1 is switched to the operating frequency of the transverter 10, and the transverter in the selected band is activated to the operating state. For example, the digital code transmitted from the host machine 1 in accordance with the program stored in an MPU of the host machine 1 is converted to an analog operation by a decoder 19 in the side of the transverter 10, thereby activating the transverter in said selected band. |
