As some probably  noted, the carrier switched between mark/space 
before/after
NMG New Olreans  transmission.  CAMSLANT was aware of the FCC ticket but did
not realize  that it was New Orleans.  As CAMSLANT controls the New  Orleans
transmitter, it is unclear (even to them) at present who is causing  the
problem.

Hi Dave,
Sounds like you are  on top of things if the QRM has been traced to the New 
Orleans
Navtex station  "G" on the  Navtex station list. It sounds plausible since 
the dead  carrier
is being heard across the country at night and New Orleans is  in a central 
location. 

I did hear the carrier switch from Mark to Space  just before the New 
Orleans transmission
at 2300UTC or 6PM EST but didn't  connect the two. Some folks have reported 
hearing
a carrier in the Great  Lakes area in the daytime? Perhaps some kind of 
coincidence?

I heard the  carrier still on at 0430UTC or 1130PM EST Sunday night. I am 
surprised at how  
steady the carrier is at night with practically no fading that I can 
discern  here in SC.

This has been an interesting problem to try and guess where  the carrier is 
coming from.
I will see if I can get any bearings on it using  a medium wave receiver 
with a good loop
if the signal stays on  overnight.  Hopefully a tech has been alerted 
somewhere that
can find  the trouble by Monday!
