A signal processing circuit, which is within a satellite reception assembly, may be operable to analyze actual frequency information corresponding to a plurality of downconverted signals. Each of the downconverted signals may be downconverted using one or more corresponding local oscillators (LOs). Based on the analyzing, one or more of the following may be determined: one or more frequency offsets associated with the one or more corresponding LOs and one or more actual guard bands. The signal processing circuit may generate information on the determined frequency offsets and the determined actual guard bands. The signal processing circuit may perform, based on the generated information, one or both of a band stacking operation and a channel stacking operation so as to prevent channels/bands being stacked on each other or being overlapped. The signal processing circuit may perform, based on the generated information, frequency corrections for channel tuning in a gateway.
