Have Quick II

In 1980 the US developed a radio system designed to be jam proof and secure for USAF aircraft, known as Have Quick. The idea was that the transmitter and reciever would both be in sync and hop from one frequency to the next, meaning it would be difficult to monitor or jam any transmission unless you knew the frequencies they would be hopping to next. Have Quick II is an advancement on the original Have Quick system, in use by both the RAF and USAF.

Although this system saw very little use initially, this has increased since 1995, and it is believed to be used by AWACS aircraft, callsigns typically NATO & MAGIC, to communicate with fighter aircraft they are controlling. Monitoring of Have Quick II frequencies is not easy, many enthusiasts use more than one scanner with the frequencies spread between them, it is also very much dependant on activity on the day you are listening. One more thing to note is that the military change their frequencies quite regularly, what you find one day, may not necessarily be there the next day.
