NRSC Publishes MDCL Usage Guidelines

May 6, 2013


Washington - May 6, 2013 - Modulation-dependent carrier level (MDCL) technology offers a way for AM broadcasters to reduce their electrical power consumption with a minimum of impact on the quality of the audio signal received by listeners. In September, 2011 the Federal Communications Commission greatly simplified the procedures for broadcasters in the U.S. to take advantage of this technology and as a result, U.S. broadcasters are more likely to embrace MDCL techniques.

To assist broadcasters in using the technology, the National Radio Systems Committee has published NRSC-G101. The guideline is now available.

The information contained in the NRSC Guideline was compiled and reviewed by the MDCL Working Group, chaired by Tim Hardy, Nautel, a sub-group of the AFAB subcommittee of the NRSC, co-chaired by Stan Salek, Hammett and Edison, and Gary Kline, Cumulus Broadcasting.

The NRSC is jointly sponsored by the Consumer Electronics Association and the National Association of Broadcasters.
