Interesting. Especially since Omega just told me they get their
Signal refresh data from satellite.

Your explanation makes a lot more sense, but it contradicts what
Omega is telling me. And even if Omega switched from FM to satellite
at some point, that still wouldn't explain my numbers, because the
most recent files are just as bad as the older ones. Maybe my
source at Omega was incorrect, and they're using FM, as they told
you.
At any rate, the point of my original post was not to impugn Signal
(or Omega, for that matter). It was to suggest that, for whatever
reason, Omega's Signal refresh files appear to have some serious
problems and probably shouldn't be used.
