I live in El Paso, Texas and my unit goes off on K-band when I pass a school bus. What gives?

Several years ago, Cobra Electronics donated $1,000,000 worth of police radar transmitters to the El Paso Independant School Disctrict (EPISD) as ‘safety devices’ If you’re driving in El Paso and approach an EPISD school bus your detector may alert you to K-band. We cannot filter/block this alert as it is the same frequency currently in use by police radar.
