Washington, DC (March 9, 2010)--Harris Broadcast Communications has provided CBS Radio with the first four-channel HD Radio digital multicast station in the country for The FAN Sports Network.
The company provided CBS Radio with the complete transmission system to support this inaugural HD4 station, including its HPX30 transmitter and FlexStar multicasting solution. Harris field service engineers assisted with the installation and launch of the new system, which operates at the recently approved elevated HD Radio sideband levels.
The technology of the HPX30 transmitter allows WJFK to transmit its HD4 "Super Sports Channel" at 13kW within the FCC-authorized 14dBc elevated HD Radio sideband level. The Harris FlexStar solution includes the HDE-100 importer v4.3, which can accommodate HD4 multicast streams, as well as the HDE-200 embedded program exporter and HDx exciter. The HDx exciter adds Harris RTAC real-time adaptive pre-correction technology to prevent signal interference, deliver linear amplification, and increase power efficiencies for lower operating costs.
HD Radio Technology, developed by iBiquity Digital Corporation, allows broadcasters to provide listeners with more programming choices via additional channels located within their existing FM frequencies. Known as HD2/HD3/HD4 channels, the stations can be accessed via an HD Radio receiver (there are more than 100 different models available at over 14,000 retailers).
WJFK-FM, 106.7 The Fan offers sports followers in the Washington, DC area subscription free access to CBS Radio's biggest sports radio stations in the Northeast, including Baltimore's WJZ-FM (HD2), New York's WFAN (HD3) and Philadelphia's WIP (HD4). Sports Radio 66 WFAN pioneered the all-sports format in 1987, and 610 WIP debuted soon thereafter. In November 2008, CBS Radio launched 105.7 The Fan, Baltimore's first FM sports station. WJFK introduced its 24/7 sports format to D.C. residents in July 2009.
