Bahrain. While close decodes have been indicative of valid decodes... not in this case. 1741 UTC = 1141 CST. Unless Chuck Norris was around here, these aren't valid.

Alert Bay. This has shown up previously, but is it today? Probably, but can't really confirm.

BTW: I have no idea what happened between ~1800~1900 & ~2000-2100. Graph shows degradation in decodes. Is that local or some DGPS nationwide problem? While I would suspect something local, I cannot rule out the latter. The USCG had nothing on the status about this. On the other hand, being in IT, I see all the time, things that broke that aren't reported (just this very week).

Do those periods of missing DGPS decodes correspond to individual I/Q recording files?

I was doing work on the system yesterday, so there should've been a break at some point, but not two like that.

Oh you know what- I was also running ADGPS a little bit. I bet that interfered and upset things. Then when Perseus started a new file, then things cleared up.
