WILL's Digital Radio plan

by Mark Leonard, general manager

For those raised on AM radio reception, the increased clarity and fidelity of FM stereo was breathtaking. Technology continues to advance, and WILL is preparing to convert its FM broadcast signal to HD.

Although many people assume that “HD” refers to high definition, as it does in television, it actually stands for “Hybrid Digital.” When a station converts to digital broadcasting, its signal remains on its analog frequency, 90.9 in WILL’s case, and simultaneously broadcasts both an analog and digital signal. This ensures compatibility with current FM receivers, while offering substantial benefits for those who purchase a new digital radio receiver.

The benefits include CD-quality sound, static-free signals, data services such as artist and song title, and possibly weather forecasts. Of particular interest for WILL is the opportunity to multicast multiple program streams on the new digital service. Specifically, WILL plans to offer both its classical music service AND its AM news and information programming on the new digital FM signal. At sunset, FCC regulations require WILL to reduce its AM operating power to avoid interfering with another station to the west. With reduced power, AM 580’s signal barely reaches the west side of Champaign, leaving many households without NPR and WILL programming.

WILL has investigated purchasing another station to fill in our AM coverage area, but none have become available. With conversion to FM digital broadcasting, WILL could maximize our AM 580 coverage area, duplicating the existing FM 90.9 reach to Springfield, all at a fraction of the cost of purchasing an additional station.

Earlier this year, WILL was awarded a Corporation for Public Broadcasting grant to cover approximately $75,000 of the $200,000 total project cost. We are embarking on a campaign to raise the balance of the necessary matching funds. We have raised $20,000 to date, with $105,000 to go.

Currently, 1065 radio stations across the country have converted to digital broadcasting, including 36 in Illinois. It is not a mandated conversion, yet the advantages have already proved compelling to most stations in major markets. At first, digital radio receivers were a rarity, however major retailers have added models to their lineups during the past year. Additionally, auto manufacturers have begun to offer digital FM receivers as an option on some models.

There is no subscription charge for HD Radio. It is over-the-air, free radio, but with increased sound quality and many more program options available.

WILL has a tradition of radio innovation dating back to the historic launch of its AM station in 1922, and it early experiments in FM broadcasting in 1941. We look forward to continuing this innovation in service and quality with the advent of digital FM broadcasting.
