The oscillation frequency of the VFO 34 is supplied to the local oscillation input terminal of the transmitting/receiving section 2. As a result, the transmitting/receiving section 2 transmits at the frequency that the receiving section 3 was receiving. Therefore, it can be used as a wireless communication device that essentially has two transmitting and receiving sections.
