[QUOTE="CyberSimian, post: 1270952, member: 141969"] So far in this discussion we have been talking about "signal strength", but now that you mention it, I think that "signal quality" is the value that we should be using to compare channels. Both strength and quality are arbitrary measures that have no absolute meaning, and TV Server scales each to fit in the range 0-100. Suppose during a scan you encountered the following: [LIST] [*]Channel "BBC2 SD" in MUX A: strength=80, quality=30 [*]Channel "BBC2 SD" in MUX B: strength=20, quality=70 [/LIST] Which channel should be retained? Surely it should be the one with the higher quality rating (MUX B). If you use strength*quality as the measure, you would choose MUX A (value=2400) instead of MUX B (value=1400), even though MUX A is likely to give worse reception than MUX B. -- from CyberSimian in the UK [/QUOTE]
