CINCINNATI, April 1, 2008 — Harris Corporation (NYSE: HRS), an international communications and information technology company, has delivered 13 Harris HD Radioâ„¢ broadcast transmitters to American Public Media for its group-wide HD Radio broadcast initiative, targeted for completion in December 2008. The phased rollout also includes three HD Radio upgrades to existing Harris Z-Seriesâ„¢ analog transmitters and Harris FlexStar® HD Radio broadcast products at each station for multicasting initiatives. American Public Media is one of the nation’s premier public radio producers, providing about 20 national programs and specials, including “A Prairie Home Companion,â€? “Marketplace,â€? and “Saint Paul Sunday,â€? that reach 14.7 million people each week.

“We are familiar with the reliability of Harris transmitters, having standardized on Harris for analog FM transmission,� said Doug Thompson, director of engineering for American Public Media. “The introduction of the FlexStar family of HD Radio broadcast products, notably the FlexStar HDX exciter, drove our interest in Harris for HD Radio transmission. The FlexStar equipment is easy to set up and administer, and we are confident we have a reliable platform already in place as more of our stations explore multicasting.�

Thompson pointed to the exclusive Harris Real-Time Adaptive Correction (RTAC™) technology for FCC mask compliance in the FlexStar HDX exciter as an important selling point, as well as the exciter’s automatic switching and redundancy features. American Public Media will install the entire FlexStar multicasting platform (HDE-100 Importer, HDE-100 Exporter and HDX exciter) at its various transmission facilities to accommodate its long-distance program distribution system originating from its St. Paul, Minnesota studios.

The majority of the 13 new transmitters are from the Harris Z-Series ZCD+ range of solid-state transmitters, with WSCN-FM in Duluth receiving a Harris HT\HD+ common-amplification tube transmitter. According to Mike Hendrickson, supervisor, broadcast station network, American Public Media, the HT\HD+ transmitter meets footprint requirements at a crowded, shared transmission facility by allowing the station to simultaneously transmit analog FM and HD Radio broadcast signals from a single transmitter.

Thompson and Hendrickson both pointed to the Harris Training School in Quincy, Illinois, as an added benefit to the overall experience. Ten American Public Media engineers, including Hendrickson and Thompson, have attended the training school, where they received instruction in a number of areas, ranging from specific operation of Harris equipment to general HD Radio theory.

“The Harris Training School was an enormous factor in getting us comfortable with the new technology, raising our confidence level for maintaining the transmitters, and providing a more direct connection to the manufacturer,� said Hendrickson. “I appreciate that the school is not just Harris-specific; there is theory about how HD Radio broadcasting works, the various combining systems, and other in-depth technical information. They also offer specific Harris product training, but the school applies to any HD Radio broadcast engineer, regardless of what manufacturer designed the equipment.�

Harris Z-Series ZHD+ and HT\HD+ radio broadcast transmitters, and FlexStar products are among the wide range of Harris solutions that optimize the HD Radio transmission and multicasting workflows of today’s broadcast operations.
