Transmitter Efficiency: Overview
The purchase of a new transmitter is among the most important technical decisions that can made by a broadcaster. This is particularly true today, due to rising energy costs and recent technological improvements in high efficiency amplifier designs. In some cases, the purchase of an energy-efficient transmitter may even pay for itself over time, particularly if care is taken to design as energy-efficient a transmission system as possible.
The Transmitter Efficiency Calculator is a tool that predicts transmitter system energy costs both for present operations and for the "what if" evaluation of prospective, future purchases. You can apply the actual, measured efficiency of your current transmitter (if available), the efficiency specifications procured from the manufacturer, or the published efficiencies of new transmitters that you may be considering. Additionally, the tool can predict the overall efficiency of typical installation configurations while considering local climate, energy costs, HVAC, and, in the case of digital FM transmission, various IBOC combining methods.
