Not that interesting.
So why don't I get certain stations very well? Sometimes it is because there is another DGPS station on the same frequency. But others have just one. For example, Rigolet NL. I ran Carrier Sleuth on my SDR recordings. Link to Carrier Sleuth: http://blackcatsystems.com/software/medium_wave_carrier_display_app.html
Here is 299 kHz:

No wonder I do not get many decodes from Rigolet. Must be one of those evil NDBs, or several actually ;D
Or 287 kHz, and Fort Stevens OR:

305 kHz, which explains (partly) why Biorka Alaska is tough here:

I have never picked up Trois Rivieres, QC on 321 kHz. Skeezix did once: https://www.hfunderground.com/board/index.php/topic,32172.0.html (It would be nice to know the timestamps, was it real?) Although I see some conflicting information online as to whether or not it is still on the air. The frequency does not look too bad here:

323 kHz is a mess though, so much for Annette Island, AK:

Oooo! This is exciting. I looked this up in my DB for station 928. First time for actually using it for something other than a money & time sink.

Valid on Jan 8? Possibly as the time is right and only station on 321.0 kHz that day. But, with two widely separate decodes, can't be certain.
These sites do not have 928 listed as online:

Yet, this one does (Date modified: 2016-12-23):

I looked through their Notice to Mariners 2015-2017, but found nothing about 928.

From some discussions on the DGPS list, it seems Trois Rivieres, QC is indeed off the air. That explains why I never hear it ;D
