PROBLEM TO BE SOLVED: To provide a radio communication device capable of modifying a reception frequency to a stipulated frequency.SOLUTION: In a radio communication device 1, when operation to measure a reception frequency is performed from an operation unit 4, a control unit 2 moves a modem 6 into a state of the time of reception to make it output a neutral signal, and outputs a reception adjusting value referring to a memory 3. On the basis of the neutral signal and the reception adjusting value, a transmission circuit 20 outputs a transmission signal for reception frequency measurement to an antenna 16. With this configuration, an operator can measure the frequency at the time of reception of the radio communication device 1 without opening an enclosure of the radio communication device 1, by measuring the transmission signal for reception frequency measurement outputted to the antenna 16. In addition, if the measured frequency at the time of reception deviates from a stipulated frequency, the operator ca
