"No! It's not like a cell phone signal!" The robber shook his head and said, "I can tell that the signal source is coming from the luggage compartment. I wonder if some bastard put something live in his luggage. Otherwise.

The British Defense Command has gathered a large number of people, a variety of high-tech talents, and various radio wave receivers have been set up. Everyone is nervously supervising this uninvited guest flying from Afghanistan. Any

"General, the other party is using the radio wave transmission method from the Second World War, and the code used is the BCD code!" The communications soldier pointed at the communication screen in surprise and said, "Look, this is the changing pattern of radio waves. There are only two ways.
