Topband: DX Window

[Tom W8JI]

While my humble station & mediocre efforts in the various Topband contests 
hardly matter much, I try & make it a point to stay off of those "window 
frequencies", unless I'm responding directly to a DX station that I might 
hear thereon...>>>

I think most contests prohibit or frown upon NA stations CQing in the DX 
Window. This should also include the keying or spurious sidebands of those 
stations.   Nothing wrong with answering the DX, but I think most 160 
contests prohibit or discourage CQ's.
