MOBILE STATION EQUIPMENT FOR AIRCRAFT TELEPHONE

PURPOSE:To eliminate to receive disturbance due to the electric wave interference from other moving body radio communication of the same radio frequency on the ground by controlling a transmitting electric power and a receiving electric power in a moving station device for an aircraft telephone. CONSTITUTION:At a moving station device 16, the output signal of a transmitting part 11, after the attenuating quantity determined beforehand is given by an attenuating part 13 for transmission, is fed through a transmitting receiving sharing part 15 to an antenna 17 for loading to an aircraft. A receiving signal, after the attenuating quantity determined beforehand is given from the antenna 17 for loading to the aircraft through the transmitting receiving sharing part 15 by an attenuating part 14 for reception, is inputted to a receiving part 12. Thus, the transmitting signal and the receiving signal are attenuated so that the signal can be transmitted and received only with a radio base station 4c which is a calling opponent. Consequently, a moving station 7 does not generate the electric wave interference between radio base stations except the radio base station 4c.
