An interesting (at least to me) addendum to this thread.

An examination of the newly downloaded nasabare keps in use by my SatPC32 showed the date of the current ISS entry to be 11/6/20. Thus not "up-to-the-second." Ed K9EK's data came from an iPhone app with unknown but obviously newer data than mine.

Keep that in mind if working the ISS that very new keps are essential as the ISS does do orbital changes from time to time.
