used nfl jerseys the challenge / response code frequency and coding Force's top-secret information

hells of anti-aircraft guns not identify, but the Fire Control Radar receives a response code lock-emitting device; Even if one of their own aircraft broke into the missile's route,throwback nba jerseys cheap, the missiles as long as the receiver to the response code will avoid it, and never will detonate the warhead. Airborne radar and later can be used to send the request code and receive the response code, but only works when the radar work, they still will be installing a recognizer.
Request code and response code in use, whether the enemy intercepted it? It is impossible. Always have endless waves sky in flying, you know that the string of the request code, the string is the reply code
?It? Of course, the challenge / response code frequency and coding Force's top-secret information, even if the user is not aware of. It is too important.
Imagine if our army seized two heavy equipment of the enemy aircraft (fighters, helicopters, tanks,used nfl jerseys, etc.), then start one of these pieces of identification, can be measured to the request code, it is aligned with another transmitter can be answered code. These two strings of code into its own identifier (like recognizer can support two groups ask / answer code, so friendly with the operations), then the enemy received the request code will automatically transponder code. Mounted shelves fighter like fitted it with the launchers.
Of course, the enemy once found this point will immediately begin to modify the operating frequency of the recognizer and coding, but this is no easy task, because of the
