Penobscot- ?? Unknown. Possible, but unverifiable with existing data.
Cape Aghulas & Kuala Besar are not valid.
According to the graph, seems that Annapolis had overridden Angleton:

There were 90 decodes from 05:08:04 to 05:09:52, so it wasn't 100%, but close.
I think that missing decodes from both stations (05:07:54-05:08:04 and 05:09:52-05:10:19) are from when the two were interfering with each other and disruption each other's transmissions.
Looks like similar pattern with Kensington & Sheboygan, Cape Canaveral & Driver, and St Louis & Youngstown. Even the brief time that St Louis was on, it dominated the frequency blocking Youngstown.

St Louis was interesting again:

Here, Annapolis is dominant, as expected since it is only 81 km away. But every so often Angleton sneaks in.
Penobscot is also dominant here, but not by the same margin, looking at a partial decode from last night 80% or so of the decodes are from there vs Louisville. Although I see Louisville is still using reduced power. Looking at older logs from Nov, there are nights when Louisville was dominant, and others when it was not. Probably the effects of daily propagation variability.
