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.

As a CW op dipping a first toe into FT4, I am wondering how a 10-KHz
segment recommendation fits with, typically, a 2700-Hz audio bandpass.
I have been spending my time with my radio set to 14.080, figuring I
was covering up to maybe 14.083. Does this suggestion envision an
overflow dial frequency of 14.085, using up to 14.088?
Looking over the rules, I'm struck by the "anybody works anybody"
aspect and using grid squares as multipliers. I'd expect this will
quickly eat up the ~50 channels optimally available on a given band
with one dial frequency. I'd like for any non-contesters who get on
to come away with a good impression, so clarification would be
welcome. Also, can someone clarify if split mode is a good idea in
this event? It would seem to reduce the channel capacity of a given
dial frequency - not a good thing!

One issue is contest mode versus non-contest mode. Non-contest mode
stations send and expect to receive SNR. Contest mode stations do not
send
SNR and don't need SNR to complete a QSO. Often confusion and
incomplete or
unlogged QSOs result.
For WW-Digi, best bet to avoid non-contest versus contest mode issues
is to
use contest mode in the WW-Digi recommended band segments.
*WW-Digi FT4 recommended sub-bands:*
1.840-1.844
3.580-3.590
7.080-7.090
14.080-14.090
21.080-21.090
28.080-28.090
*WW-Digi FT8 recommended sub-bands:*
1.844-1.848
3.590-3.600
7.090-7.100
14.090-14.100
21.090-21.100
28.090-28.100
Use non-contest mode in the traditional FT8 and FT4 band segments.
For non-contest mode: WSJT-X, File, Settings, Advanced, UNCHECK Special
Operating Activity.
For contest mode: WSJT-X, File, Settings, Advanced, CHECK Special
Operating
Activity NA VHF.
W6SX vision for WW-Digi is the huge pool of non-contesters out there. My
hope is they will dip their toes in contest waters and find they like
it.
This will be an opportunity for contesters and contest clubs to
encourage
and help them to try legacy-mode contesting.
Contest Exuberantly,
Hank, W6SX
