I think it is called l d e or long delayed echo.

I actually experienced one of these one night on 80 meters talking to some 
friends in Nebraska.  We had a delay of about a second.  You could let up 
on the mike and hear your last word or so.  Two or three of us experienced 
it, although to the other person the signal sounded fine.  Now, one second 
isn't much, but consider how far that signal had to travel, bouncing 
around the atmosphere or whatever.  Quite a bit for 186,000 miles
