Alaska Public Radio Tests AM Transmitter Efficiency with Harris Support
Mason, OH - Apr 7, 2011 - Harris is supporting Alaska Public Broadcasting tests for improving AM transmitterefficiency through Adaptive Carrier Control, a technique used to reduce power consumption. Harris has also engaged with the FCC to open the possibility that more U.S. broadcasters can evaluate this green technology moving forward.
The Harris Adaptive Carrier Control (ACC) system is capable of several power reduction algorithm operations. These include Dynamic Carrier Control (DCC), which employs many power saving curves; and Amplitude Modulation Companding(AMC), which also yields energy savings. Together, DCC and AMC efficiencieswithin the Harris ACC system can potentially reduce operating costs by up to 35 percent.
Harris has been providing ACC systems to international customers since the launch of the Super Power DX AM transmitter in 1993. Alaska Public Broadcasting is testing the Harris ACC system within its operational Harris DX10 transmitters, taking advantage of an experimental license obtained from the FCC. The Harris ACC system can also be used in Harris 3DX and DAX AM transmitters, for both new and existing installations.
