There are differences between TP-s if you look at above sites.
Satellites.XML short example:

    <sat name="15.0W Telstar 12 Vantage" flags="1" position="-150">
        <transponder frequency="10983000" symbol_rate="45000000" polarization="0" fec_inner="8" system="1" modulation="1" />

        <transponder frequency="11506000" symbol_rate="2894000" polarization="1" fec_inner="3" system="0" modulation="1" />

Which is true or more precise?

To know that, just read websites like kinofsat or lyngsat to know which are the active channels. Did you choose in your first website the option to include only the currently active channels?

 

[EML]

I think flysat is the best and most accurate

THX. And of course, I have choosed the option "Only Active".
