OK, this may be off topic but I did hear the signal with my R-390. It 
is happening now
on 520 KC. A carrier with some type of data and the letters in CW, YWAT. 
After
that GM. Weird place for utility stuff.

Sounds like you were hearing a mix of signals on your R-390. Navtex RTTY 
weather data on 518KHz, Beacon YWA with a long dash from Petawawa, Ont. on 516KHz 
and beacon GM from Greenville, SC on 521KHz. Try using the BFO and a narrow 
bandwidth and you should be able to separate the signals. 73 Todd WD4NGG
