"Google did, for WLO at least: seems like it's a weather fax station in New Orleans and someone's receiver could maybe use some calibration."
My reciever is calabrated, it is crystal controlled. I have cheched it's frequency on my scanner. You need to do more research before jumping to conclusions.

I have seen similar beacons. From what I can tell, they are NOAA beacons, but I haven't been able to find out a whole lot about their purpose. They use the same three letter identifiers as many of the NOAA weather fax stations, but not the weather fax frequencies. I have always assumed that it is probably some sort of automatic weather data beacon, as the repeated data bursts after the morse ID always sounded like 200-300 baud FSK data of some sort. I would be interested to learn what exactly they are.

Tonight I have copied "NOJ" around 19500khz on spectran and found a translation error. This solves the mystery because WLO, NMN and NOJ link to the Night of Nights VIII beacon event.

Nice find, now we know who is beaconing. It would still be interesting to know why. This isn't the Night of Nights event. The beacons seem to be operating continuously, automatically, and with some kind of data.

Today I found two more beacons with the same ID. A google search found that they are comming from Turkey. This is some DX. Look for 4216.0Khz and 4219.0Khz.

Wow, they are booming here here as well. I've got TAH on 4.216 and 4.219. This capture also shows a station just underneath. The morse reads DE LZW LZW. Google says that one is in Bulgaria.

I have picked up a few more beacons around 8.421Mhz: two WLOs NMC NMN NMO
8.441Mhz: AMA
Update: Another beacon on 4218.5Mhz This one sends an ID of "DE LZW LZW" with a 40 seconds space between ID. This is from Varna Radio, Bulgaria
This not a beacon in the sense of an RDF beacon, though it is an automated transmission.
DE means 'from' or "this is." Hence "DE LZW" means 'This Is Varna Radio'. LZW is telling ships that it is listening for radio traffic from them on this frequency. The spaces between transmissions are for ships to respond. Maritime Coast Radio Stations also use 'frequency clearers' - repetitive transmissions designed to stop others from transmitting on their calling or working frequencies.
