A bit more information needed.
Do you see this for all the satellites, or just one?
Which Keplerians are you using in SatPC32? Celestrak or AMSAT?
Is the difference consistent with one source always early?
Do you have a minimum elevation selected in SatPC32?

<I have noticed that when I update the Keplerian Data for my location on
<SatPC32 and generate a list of passes they all seem to be about 5 minutes
<different than the predictions from the AMSAT website. This is for the
<earliest pass, and I am using the exact GPS coordinates for my location.
<So which do I rely on? Which predictions should I consider the "gold
<standard" for passes?
