The invention relates to the improving of the resistance to intentional or unintentional jamming, of a receiver of spread spectrum radio signals transmitted by polarized wave. An absorber may have a gas inlet for receiving the flue gas from the heat exchanger, an inlet for receiving a desiccant solution and a media receiving the desiccant solution for providing surface area contact between the flue gas and the desiccant solution A dual cooler may include a first side through which a heat exchanging fluid and the desiccant solution may be directed for cooling. The signal generator generates first and second signals based on a clock signal, such that the first and second signals have a phase separation of about 90 degrees. During these tuned-away periods, the client device may suspend operation on the tuned away network for extended tune away intervals.
