[Lowfer] 518 kHz Navtex QRM

[Garry Hess]

The night-time carrier at the 518 kHz Navtex mark frequency continues. 
It nulls at about 60 degrees, implying a direct heading of about 150 
degrees. That direction, plus a screen capture showing the mark 
frequency is identical to that of area 4 station E, makes me suspect 
that's the culprit.

Conditions must have been fairly good to the West last night because 
area 12 west coast stations C, Q, and W decoded with the interferer nulled.

I've alerted the individuals that handled my last Navtex failure report 
in hopes that their emails are still valid. Unlike DGPS, I haven't found 
a web site for reporting Navtex problems. Does anyone know of one?
