• Abstract:
  A study was carried out of two tests for the prediction of motor-vehicle interference in an on-board radio. The tests were Texas Department of Transportation (TxDOT) Tex-899-B and Society of Automotive Engineers (SAE) J551/4, and the vehicles and radios of interest were new TxDOT pickup trucks and TxDOT two-way FM radios. The study involved a vehicle-testing component in which both tests were conducted on eleven trucks and a laboratory component in which TxDOT radios were subjected to simulated vehicle interference. The results show that, unlike Tex-899-B, J551/4 is not well suited to predict the occurrence of interference in the TxDOT radios, but it could be modified to do so. Some questions remain regarding the implementation of the modifications.
