[Lowfer] Navtex QRM 518 kHz-more

[David L. Wilson]

The carrier did come back.  Apparently they have not fixed the problem.  I
will talk to them again.  I have a contact number and the day person will
likely be different and may know better what to do.
When it disappeared they may have done something and then undone it thinking
they had fixed the problem.
