Harris Corp. announced the installation of PowerCD high-power UHF ATSC transmitters at two TV stations owned by Quincy Newspapers Inc., of Quincy, Illinois. The installations satisfy FCC requirements for full-power DTV broadcasting at KTIV-DT Sioux City, Iowa, and WVVA-DT Bluefield, W.Va.
“Due to the proximity of Harris’ manufacturing and service center to our offices, we have developed a strong, long-standing relationship with Harris and many of its employees. We have been buying Harris transmitters exclusively for our stations based upon our experience with their rock-solid reliability and impeccable customer support,” said Brady Dreasler, director of capital, facilities and engineering for Quincy Newspapers. “The primary reason we chose the PowerCD transmitter is that its newer IOT design promised exceptional energy efficiency and savings on our energy bills. Our expectation is that they will deliver greater energy efficiency than the previous generations of IOT-type transmitters. We estimate that the energy efficiency of the PowerCD transmitters will enable us to meet our return on investment 18 months sooner than any other transmitter.”
The Harris PowerCD transmitter is based on new, high-efficiency depressed collector Inductive Output Tube (IOT) power amplifiers, among other technological advances.
With its new PowerCD transmitter now online, NBC affiliate KTIV has increased its digital power output from 1.8 to 57 kW with an ERP of 1 MegaWatt, while CW affiliate WVVA increased its power output from 7.5 to 51 kW, also with an ERP of 1 MegaWatt. The transmitters replace smaller, low-power Harris DiamondCD solid-state UHF DTV transmitters. Quincy Newspapers also owns several Harris FlexiCoder and NetVX ATSC MPEG-2 encoding systems. Using the Harris eCDi transmitter network monitoring and control system, the stations’ chief engineers can troubleshoot and adjust the transmitters from their desktops without traveling to the tower sites.
“Remote diagnostics using the GUI of any desktop PC is invaluable. It enables our engineers to quickly determine if any issue can be remedied remotely, or if the repair can be delayed until a more opportune time,” said Dreasler. “It saves our engineers the considerable time associated with driving to the transmission sites, which in the winter months is not always practical.”
