Abstract

PROBLEM TO BE SOLVED: To provide an FH radio communication system in which, even when FH transmitter-receivers are at a distance from a control room, various setting operations or the like with reference to them can be performed from the control room via the small number of cables. SOLUTION: When various functions of FH transmitters 11 to 1N and FH receivers 31 to 3N which are at a distance from the control room 50 are set in the FH radio communication system 1, the functions are set with reference to a partner according to a control program when an operator gives an instruction by using a switch, the control program and the like as the function control means of a remote control device 60 in the control room 50. A monitoring operation with reference to the transmitters and the receivers is performed in the same manner. Consequently, it is not required for the operator to go to the FH transmitters in a transmitting room or to the FH receivers in a receiving room. Since their operations are controlled by the transfer of serial data, substantially only two transmission cables are required.
