Federal Highway AdministrationUS Transportation CollectionThis report describes the second and final phase of a study of vehicle-generated radio interference in Texas Department of Transportation vehicles. The results of the first phase are contained in a 1998 report. The emphasis throughout the study has been on the test methods used to characterize the interference. The second phase took place over the 16-month period from May 1, 1999 to August 31, 2000. Three faculty members and three students carried out the research at Texas Tech University. The Main results of the study were the formulation of an expanded version of the TxDOT Tex-899-B test, worked out in cooperation with the vehicle manufacturers, and the determination that other versions are possible, but while more precise, suffer the drawback of added complexity.79
