For the instant on / constant on, test cones were placed at 1½, 2, and 2½ miles from the radar guns. The cone at 2½ miles was slightly over a hill and the test vehicle was out of sight of the radar van. Test vehicles were stationary. Officers triggered the radar guns for less than two seconds in the instant on configuration and for approximately five seconds in the constant transmit position. A MPH K-55 X band gun was used along with a Decatur GHD K band and a MPH Bee III (33.8 GHz). Police officers were in the test vehicles and reported the radar detector results. Radar detector makers accompanied the police officers in the test vehicles. All test vehicles began at the 2½ mile cone and after all detectors encountered all radar guns, two tries each detector, the test vehicles move to next closer cone. "Y" stands for Yes and means the detector correctly reported radar. "N" stands for No and means the detector did not detect radar. Beginning at the 1½ mile cone signal strength was recorded. "YF" stands for Yes/Full and means that the detector correctly reported radar and the detector was in full alert. "Y5/9" stands for Yes radar was correctly reported but only 5 of a possible 9 leds were being illuminated, indicating signal strength. Every detector tested had two tries. - SML 2004 Detector Test (June 11-13, 2004)
