KD6PAG was correct, suggesting a look at the AO-27 web site:
It looks like the TOPR was reset on the satellite yesterday, as the "TOPR
Epoch (UTC)" now shows 31 January 2007. The web site has this bit of news:
January 31th, 2007 UTC
Allen, N5AFV is working from Honduras, Belize, Cozemel and from sea.
For the next few days, the schedule is shifted 7 minutes early but is
extended to 8 minutes ontime. The web site has the correct times.
Thanks you Allen for the contact from V31 land.
Also of interest is that N1XAU was heard on a pass today.
N3UC - one of the AO-27 control stations - commented on 20 January during
an AO-27 pass that the batteries were in good shape and the transmitter was
working well, and he had extended the repeater time for 2 minutes during one
eastern North American pass. It's possible that he extended the repeater time
shifted the time a little earlier to allow more stations - especially
south - a chance to work AO-27 while it is currently functional. The
be in pretty good shape, if N3UC went ahead and made these changes.
Good luck and 73!
