Abstract

PURPOSE:To realize an automatic control for the frequency of a called station form a calling station, by transmitting both the address and frequency information to the called station from the calling station and then securing an automatic setting for the frequency of the called station. CONSTITUTION:The transmitter/receiver 1 of the calling station transmits both the address and frequency information to the called station 2 before talking with no units added and in an optional frequency among the allotted ones f1-fn. At the station 2 the sweep receiver 11 always receives with sweep the allotted frequencies f1-fn to demodulate the reception telephone and then sends the demodulation output to the signal detection circuit 13. The circuit 13 detects a coincidence between the demodulation output of the receiver 11 and the own address set at the own address setting circuit 12, and then deliveres the subsequent frequency information to the frequency setting circuit 14 when a coincidence is obtained between the address of the reception telephone and the own address. The circuit 14 sets the frequency of the receiver 15 based on the frequency information which is the output of the circuit 13.
