The buzzing sounds are in a different sequence, I haven't noticed the pattern yet. The weak/fading signal at my QTH doesn't help much.
I still hear it, but I have not yet heard a CW ID today. (Maybe I just missed it in the static?)
You didn't mention if it was transmitted with an AM carrier (constant needle deflection like local AM radio) or just CW & data (signal meter only moved during the times of CW or data).
While most of the LORAN (network of radio-location beacons for aircraft and ships at sea) have been closed down, there are still stations on HF that carry out similar tasks. Last summer I heard a VERY loud AM carrier signal that ID'ed on CW but carried no other information--it was in the same frequency area, give or take a mHz or so that you mention.
I found the "company" website and emailed a signal report. Within an hour a lady emailed me back saying it was indeed them and the she was also a ham. The signal was like 10 kW and on a 600' vertical antenna out in North Carolina somewhere. The "company" was a commercial venture but also provided radio-location for aircraft and ships as a "beacon" of sorts, but also sent information using digital modes (computer modes) the information was not public and was only for their subscribers. Since GPS is common place now beacons for air/ship are fairly antiquated I have no idea what they were sending via digital modes (most likely the buzzing sound you copied). I will have a computer with digital mode capability connected to my Yaesu in the next few months I do not as of yet have the capabilities.
But then again I might be wrong and your signal may have a different purpose.
And thumbs up for knowing CW!!
