Dorrough Says AMS Could Increase AM Modulation

Dorrough Says AMS Could Increase AM Modulation

A new modulation technique for AM broadcasting is being touted by industry pioneer Mike Dorrough. He says the Advanced Modulation System can increase carrier modulation to 200%, improving the performance, range and sound quality of AM radio. He discussed the system at a recent meeting of SBE Chapter 43 in Sacramento and plans other presentations.
Ross du Clair, CE/DOE for Clear Channel in Sacramento, who attended the meeting, said, “This is real and it does work. No modifications were needed to a standard AM receiver for it to work.” Details will appear in an upcoming issue of Radio World. Dorrough was given the NAB Radio Engineering Achievement Award in 2000 for his contributions to audio processing and monitoring.
