Mike, LF,
Further to my previous reply.
If you look at my grabber & click the 472-479kHz image you
should be able to link to a recent history.
You will see the signal on my grabber saves during the early hours
of today & last night.
The center frequency appears to be the same as the "BIA" NDB.

I presume this has been discussed before and I missed it.
What is the origin of the quite strong, wide RTTY-like signal on
474.0kHz? It appears to be commercial as it is on continuously, and
it comes up after dark every day.
For a while I presumed this was a funny on my receiver, but it
appeared on another receiver with different architecture, and also on
DK7FC's grabber.
