PROBLEM TO BE SOLVED: To provide a radio communication system that uses a Morse signal, reduces the reception of noise, and can easily analyze a signal.SOLUTION: A radio communication system according to the present invention comprises: transmission means for transmitting a transmission signal including a Morse signal composed of carrier waves transmitted intermittently; and reception means for automatically receiving the transmission signal. The reception means includes automatic gain control means, and the Morse signal is shorter in an interval Dbetween two points and an interval Dbetween two codes than the time constant of the automatic gain control means.SELECTED DRAWING: Figure 4 |
