I did another overnight run with DGPS last night.
All of these seem real, except the two Asians, both on 298khz.
On the graph, the two Asians would always show up at the exact same time, so maybe a bug or database error.
I see from Chris' last graph, he also has those two at the same time.
Western Head, NS would show up during the few fades from Tampa.
Most of the Lincoln, CA logs occurred after Card Sound, FL faded around 1130UTC.
