Abstract

This paper consists of a project outline. The outline contains the following elements: Area of Research; Sponsor; Time Line; Background/Motivation; Objectives; Procedures; Results and Recommendations Regarding Tex-899-B; and Results and Recommendations Regarding the Relationship of J551/4 to Tex-899-B. The area of research is motor vehicle electromagnetic compatibility and the sponsor is the Texas Department of Transportation (TxDOT). In the past, interference produced by electrical systems of some TxDOT motor vehicles limited the range of onboard two-way FM radios operating at low-band VHF. To help combat the problem, a vehicle-interference test, Tex-899-B, was devised by TxDOT to screen vehicles. New vehicles frequently failed the test, requiring one or more custom modifications in order to pass. Vehicle manufacturers prefer a simpler test like the Society of Automotive Engineers (SAE) J551/4 test.
