NRSC Releases Details of AM Band RF Noise Study (Radio World)<\/a><\/h2>\n

Noise levels remained consistent throughout different environments, even in downtown Baltimore<\/em><\/p>\n

The National Radio Systems Committee\u2019s AM Improvement Working Group has published a study examining the effects of RF noise on AM radio reception in cars.<\/p>\n

Radio World readers will find the study\u2019s scientific detail of interest. Noteworthy was how RF noise on the road often did not vary amongst the diverse environments sampled. Overcoming downtown building signal degradation was more of a concern, according to the study\u2019s authors. Additionally, the study found field strength projections of AM signals to often not be reflective of contour predictions.<\/p>\n

The group\u2019s study intended to provide a better understanding of how AM radio reception is affected by RF signal strength and noise in a range of roadway environments. The authors also provided some suggestions to overcome signal loss. [Continue reading…]<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
