648 results about "HAVE QUICK" patented technology

HAVE QUICK (also HAVEQUICK, short HQ) is a ECM resistant / frequency-hopping system used to protect military Aeronautical mobile (OR) radio traffic. Since the end of World War II, U.S. and Allied military aircraft have used AM radios in the NATO harmonised 225–400 MHz UHF band (part of NATO B band) for short range air-to-air and ground-to-air communications. During development and the procurement of UHF radios, military planners did not require features to secure communications for aircraft and helicopters from jamming until the post-Vietnam War era. Progress in electronics in the 1970s reached a point where anyone with an inexpensive radio frequency scanner or receiver set could intercept military communications. Once the target frequencies were identified, radio frequency jamming could easily be employed to degrade or completely disable communications.
