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.

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.
