This article discusses a debate between broadcasters, including New York Public Radio (NYPR) and Press Communications, over a proposed rule change by the Federal Communications Commission (FCC) regarding FM stations’ use of asymmetric sideband power for digital signals.
The FCC’s new rules, which were approved last September, are designed to enhance digital signals and improve their reach and ability to penetrate buildings. However, Press Communications has raised concerns about potential interference from asymmetric sideband power, calling for expanded reporting requirements for stations using this technology.
Press Communications argues that the new rules should include proper notification and periodic reporting to prevent interference, citing a study conducted on FM stations in the Philadelphia market that showed deviations in sideband power. They believe that more oversight is necessary, particularly for Class A stations, which they argue are most vulnerable to interference.
On the other hand, NYPR and other broadcasters, like iHeartMedia and Educational Media Foundation, contend that the proposed reporting requirements would be unnecessary and burdensome.
NYPR has criticized the methodology of the study by Press Communications, claiming that field measurements of digital radio signals are unreliable and do not accurately reflect real-world conditions.
They argue that there is no evidence of harmful interference from HD Radio operations in the past two decades, making the additional reporting requirements unnecessary.
The issue also ties into broader concerns about the viability of HD Radio for smaller, lower-power stations. Press Communications has called for a blanket power increase for Class A stations to make HD Radio more financially viable and encourage its adoption.
The ongoing discussions reflect the tension between ensuring technical standards are met to avoid interference and minimizing the regulatory burden on broadcasters.
