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 .
