Topband: FT8 on 160m

To me, the issue comes down to contained 
or not contained when it comes to signals 
on the bands. We're already contained by 
the limits of the band itself so there's 
effectively a finite space for everyone 
and if FT8 or RTTY or XYZ wanted to and 
was allowed to be everywhere, the QRM 
would be terrible.

As I see it, contained is better than 
un-contained in that the smaller dedicated 
area for digital/RTTY leaves a much 
greater area devoid of it.

FWIW, during the CW contest I had the 
filter down to 50Hz, heard DX above me and 
realized I was also hearing FT8 & I'd 
crossed into that "sub-band" I didn't 
respond to their CQ because to me, that 
would be intentionally QRMing someone not 
in the contest. O'course in the contests 
we don't want to QRM another contester 
either but we want to be heard first, so 
it can be a pig Pile, but that's part of 
the game.

73,
