SBE Chapter 56 Meeting Minutes of June 24, 2020

Virtual Meeting – Go To Meeting Conference

Program: All-Digital AM Radio Presented by Jeff Welton – Nautel

In November 2019, the FCC issued a notice of proposed rulemaking (NPRM) under the docket for revitalization of the AM broadcast band. The purpose of the NPRM was to solicit comments on the use of MA3, all digital AM broadcasting, using HD Radio™ technology. This presentation will look at the structure of the MA3 signal, benefits it can offer and the gotchas as related to the average station: What needs to be addressed, what might need improvement, what will work as is. The goal isn’t to argue whether IBOC is the best solution or not, but how to make it work to the best of our ability and raise awareness of possible issues, before they become problems.

Jeff Welton, CBRE, has worked with Nautel for 30+ years. He is currently the Nautel sales manager for U.S. Central Region. Previously he spent 16.5 years as a Nautel customer service technician, and was involved in the 2015 MA3 field tests with NAB Labs. A regular speaker and contributor on broadcast engineering, Jeff has been recognized with the following awards: 2020 NAB Radio Engineering Achievement Award; 2019 APRE Engineering Achievement Award; and 2018 SBE Educator of the Year Award. He’s also contributed to the most recent edition of the NAB Engineering Handbook and performs several presentations a year in the area of broadcast engineering.

Please plan to join us on our next virtual SBE Meeting as we discuss the technology behind the all digital AM Radio.
