[QUOTE="davemurgtroyd, post: 1087477, member: 319227"] Not only are there are signal strength variations at the transmission end but they can also be caused by the reception kit - tuners and lnbs can (and do) have peaks and troughs in their sensitivity to different frequencies, cable length between lnb and tuner can also have troughs in signal due to harmonics of reflections (from every joint) causing interference at particular frequencies. With transponders being on multiple satellites it is impossible to accurately align a dish (particularly large ones) for a maximum signal on all satellites amd alignment is always a compromise for optimum reception on all. Without professional equipment you are highly unlikely to find the reason (or combination of reasons) why your particular system reacts as it does. You can only set up your system for optimum across all required channels [/QUOTE]
