NPR Labs To Study HD Interference To FM Service

The CORPORATION FOR PUBLIC BROADCASTING has awarded a grant to NPR LABS to study HD RADIO service, including power levels needed to improve coverage while protecting analog and subcarrier service. The new $350,000 study, expected to be completed by the end of the SUMMER with findings presented in time for the NAB RADIO SHOW in PHILADELPHIA in SEPTEMBER, is intended to build on earlier research by NPR LABS of digital radio coverage, which found that FM stations would in some cases experience substantial interference from HD signals if the power increase was not closely managed.
"We’re pleased CPB has selected NPR Labs to expedite a detailed technical analysis so we can resolve these critical issues," said NPR VP/CEO VIVIAN SCHILLER. "NPR is committed to advancing HD Radio TM and protecting the quality of the listening experience for all of our audiences. If the power increase is not carefully managed, NPR member stations risk losing audience to signal interference."
"It’s absolutely critical that industry guidelines are established to ensure a well-managed and responsible power increase that maintains universal service for public radio stations," said CPB SVP/Radio BRUCE THERIAULT. "The industry collaboration involved in this study will generate technical data needed to inform decision-making on best options for elevated digital radio power levels."
