[CQ-Contest] WW-Digi Thoughts and Suggestions

Operating over a 10 KHz segment with a 2.7KHz audio bandwidth means we 
get to actually tune our rigs to make additional contacts.  I don't 
think that's a bad thing, and you can set multiple frequencies for the 
same band in WSJT-X (i.e., 14080, 14082, 14084, etc) so that changing 
frequency doesn't even require you to spin the dial on the rig .... you 
just drop down and click.

There really isn't anything like "channels" in FT8, and 2.5KHz can hold 
considerably more than 50 simultaneous QSOs.  If signals are clean a 
tremendous amount of overlap is still possible with good copy.

Lastly, split mode (either rig split or "Fake it") is almost always 
desirable, contest or not.  I really don't understand why so many FT8 
hams keep answering a CQ'ing station on his calling frequency. It's 
counterproductive and simply makes no sense.  The mode provides pretty 
much equivalent copy across the entire audio bandwidth and there are 
obvious benefits for everyone to spread out as much as possible, so why 
cluster???  If you call CQ and three people jump on your frequency to 
answer you, your ability to copy any one of them is much less than if 
they had spread out.  FT8 is great for handling overlapping signals, but 
zero beat QRM is still QRM and WSJT-X will do its best to zero beat.  
The more uniformly spread EVERYONE is the better.

The only reason I have ever heard why it MIGHT once in a while make 
sense to call a station on his frequency is the idea that he might have 
chosen a less busy frequency to call CQ, but that quickly gets negated 
if everyone calls him there.
