2. Investigation by the Enforcement Bureau's Denver Office revealed that on April 7, 2006, a Part 15 device, located at a Midas store in Centennial, Colorado, was causing interference to aircraft approaching Denver International Airport on frequency 123.850 MHz.
4. On April 7, 2006, the Federal Aviation Administration's ("FAA's") Denver International Airport ("DIA") Spectrum Manager reported interference to aircraft approaching a DIA runway on 123.850 MHz. Later that day, agents from the Denver Office investigated the allegation and located the interfering signal on 123.850 MHz to a Midas store in Centennial, Colorado. Further investigation revealed that the source of the interfering signal was a Hunter DSP 400 Wheel Alignment System, which was acting as an unintentional radiator. The wheel alignment system was also found to be producing a signal on 108.500 MHz, a frequency the FAA uses for their Instrument Landing System.
