Topband: Window ?

[Bruce]

  The DX Window is 18025 to 18030 - transmit in
 here, and listen outside the window.

The last information I had was this 160 meter DX window was no longer in use 
as a window by a international agreement of amateurs. It previously
restricted North Americans from calling CQ DX in it, while allowing other 
countries to do so. I was one of the Americans calling CQ DX run out of the 
window years ago !     Has the window changed again ?
