National Radio Systems CommitteeThe National Radio Systems Committee (NRSC) is a technical standards-setting body cosponsored by NAB and the Consumer Technology Association (CTA). In October, the NRSC’s three subcommittees met in New York in conjunction with NAB Show New York 2023 and each adopted a new document, which have now all been published on the NRSC website and may be downloaded free of charge.

  • NRSC-G102, AM Carrier Synchronization Guideline, was adopted by the AM and FM Analog Broadcasting (AFAB) Subcommittee, chaired by Martin Stabbert, vice president, of Engineering, Townsquare Media. This new document provides a summary of the benefits of synchronizing AM carriers and discusses the methods and types of hardware available to achieve high accuracy, easily implemented AM carrier synchronization using both current and legacy transmitters.
  • NRSC-G304, Metadata for Streaming Audio Handbook, was adopted by the Data Services and Metadata (DSM) Subcommittee, chaired by Steve Shultis, chief technology officer, New York Public Radio. This new guideline for radio broadcasters and netcasters describes how to use metadata with audio streams. It focuses on the HTTP live streaming (HLS) and Dynamic Adaptive Streaming over HTTP (MPEG-DASH) methods of audio streaming.
  • NRSC-G202-B, FM IBOC Total Digital Sideband, Power for Various Configurations, was adopted by the Digital Radio Broadcasting (DRB) Subcommittee, co-chaired by E. Glynn Walden, consultant, Audacy, and Jackson Wang, president and CEO, e-Radio, Inc. This is an update to a previously-adopted guideline which gives broadcast engineers an easy-to-use, quick method for determining an FM IBOC station’s authorized digital sideband power level based upon the station’s operational configuration

Anyone who has a business interest in the technology being investigated by the NRSC is welcome to join and participate in its activities. Member representatives of the NRSC are generally engineers, scientists or technicians with in-depth knowledge of the subject being studied. In order to promote the free exchange of ideas during committee work, members of the press are not allowed to attend NRSC meetings. However, members of the press are free to contact committee chairpersons, NAB or CTA with general questions about meetings. Please contact for any questions or additional information regarding the NRSC.
