Abstract

PURPOSE:To enable stable transmitting-receiving with a low power consumption by controlling the transmission and stoppage of the transmitting circuit of a counter station based on a receiving level. CONSTITUTION:The signal of a frequency f1a transmitted to a counter station by a transmitting circuit 3 is received by a receiving circuit 5 of the counter station, receiving signal level information 30 is sent to a receiving signal deciding circuit 20 and compared and decided with a setting level. When the deciding result is larger, a control signal 31 is sent to a receiving signal deciding circuit 21 of the counter station with a service band 50 and the power source of the circuit 14 of the counter station is turned off. When the deciding result is smaller, the signal 31 turns on the power source of the circuit 14. Consequently, the circuit 14 sends the signal f2a, and concerning an up-line, a usual 1+1 frequency diversity radio line is constituted. In the same way, based on a signal sent from a transmitting circuit 13 to the counter station, the power source of the transmitting circuit 14 of the counter station is turned on and off and a line is constituted.
