[QUOTE="MCelliotG, post: 1119285, member: 404726"] Let me solve your problem once and for all: [ATTACH type="full" alt="snrdb.jpg"]138837[/ATTACH] And now let me ease your concerns. You are simply a "victim" of comparing SNR signals in percentages between different tuners and receivers. Take a minute to ask yourself what you are actually comparing, a percentage level of what exactly? Is there any globally accepted maximum value when it comes to signal that should represent that a digital signal maxes at 100%? These signals are subject to a ratio of useful signal compared to noise called Carrier to Noise or C/N. This produces a limitless value that is measured in dB. Professional tuners, such as the Silabs tuner you have on your SF8008 is more than capable of reproducing and measuring C/N in quite an actualized manner, so changing the value in the menu I show you above from percentages to dB will give you exactly what you actually receive in signal strength. Usually anything above 14 or 15db when it comes to satellite reception is a significantly strong signal. So compare your signals in dB and you're good to go! [/QUOTE]
