Some nice catches in there. This is with a 500 ft longwire (eventually you can call it a beverage once I terminate it), low pass filter, SDR-14, and my Amalgamated DGPS software, more details here: https://www.hfunderground.com/board/index.php/topic,29766.0.html

I note that on some frequencies, multiple DGPS stations are being reported. Is this due to the yin and yang of propagation?

Yes, in most cases. There are at least two stations that I think are just corrupted messages, Wiarton and Angleton. In other cases, you can see the various stations fade in and out, on the bar graph chart that I posted in the other message, I should probably post it here as well:

I re-ran the recording file, after
making some improvements to fixing some bugs in the decoding software. Quite a few more decodes from the weaker stations. And even some new ones, like the UNID on 325 kHz, that seems to be a station in Montana that the USCG forgot to turn off.
