HD Radio Power Boost Requested

HD Radio stations are authorized to broadcast with the power equivalent to 1% of a station’s analog power. The FCC mandated that to make sure they wouldn’t interfere with analog signals. Now, a group of 18 broadcasters, four equipment makers and IBIQUITY are saying the HD signals don’t go as far and have a harder time penetrating buildings.
IBIQUITY CEO BOB STRUBLE said, "As HD Radio technology moves further toward the mainstream, it’s crucial that we continue to add new features and enhance the technology’s basic capabilities. Working with the broadcast industry and equipment makers, IBIQUITY DIGITAL has completed extensive testing on higher-power FM HD Radio broadcasts and the results are clear. Increasing from 1% to 10% of analog broadcast power greatly improves digital performance without meaningfully increasing interference."
Studies by IBIQUITY and CBS RADIO engineers in NEW YORK, LOS ANGELES, DETROIT and NEW JERSEY report the average Class A FM’s coverage area grew by 67% and the typical Class B jumped 56%. Engineers in LOS ANGELES tested building penetration in houses, office buildings and underground parking garages using CBS Alternative KROQ, and found the boosted HD signal did even better than analog.
