A system includes a processor configured to receive vehicle GPS coordinates. Digital samples are obtained during operation of the vehicle which are related to the system. The method is of use in improving the efficiency and power capabilities of amplifiers for use in mobile communication base stations. A steering signal is sent to the steering actuator based upon the lateral offset compensation value and the slope offset compensation value. A final amplifier stage power distribution network is configured to distribute power from a final amplifier stage power supply to a final stage of the amplifier circuit. The valve is selectively displaceable between a closed position whereby the suction inlet is sealed off from fluid communication with the suction generator and an open position whereby the suction inlet is provided in fluid communication with the suction generator.
