Hello Gary,

It would be very nice to have a US band 600 meter grabber over on your 
side of the pond. Our stations run from 505 to 508kc. Most stations that 
call CQ or 2 way QSO go up to the 506-508kc part of the band. All 
activity is from local sunset so lets say 23:00utc to well past your 
sunrise time. That 518kc NAVTEX is a solid S-9 here at night. Wonder why 
it puts a image in your RX at 505.6kc? Have you tried a real tight 
lowpass filter? Could it be a broadcast band signal mixing with the 
NAVTEX signal creating the problem?

Maybe a good idea would be for the US guys to post to the RSGB reflector 
when they are on the air to increase the chance of a EU station to 
listen for our signals? I don't know who stays up late over there. There 
are not many US guys who stay up late...hi hi...I am retired so I can 
stay up to sunrise...hi hi...
