。The carrier wave oscillator consists of a transmitting circuit section with a modulator that modulates the carrier wave with an audio signal and outputs it, and a frequency converter that inputs the antenna input signal together with an external high frequency signal to a mixer to obtain an intermediate frequency signal. What is claimed is: 1. A simultaneous transmitting and receiving device comprising a receiving circuit having a receiver circuit, wherein the carrier wave oscillator is connected to the mixer, and a carrier wave oscillation signal is input to the mixer.
