Sounds like the USCG ... got one here in Milwaukee 297khz ... sounds like RTTY
(teletype) ... it's 30db over S9 here ... makes a nice reference signal for
antenna work. I forget the official name for this type of LW service.
NAVTEX is only broadcast on one frequency (518) as far as I know. I wonder if
you might be hearing Differential GPS?
Navtex is also on 490 KHz in some areas as well.
