And remember the rate of FT8 vs. RTTY in a dxpediton setting. Depending
on the pileup and RTTY op skill, dxpediton RTTY rates can be miserable.
FT8 is the silver bullet for the signal level as Jim mentions plus the
rate improvement. A win-win from a dxpedition cost per QSO standpoint
in a digital mode!

It's great that they're doing this, but the importance of FT8 is that
it allows us to work 10 dB deeper into the noise that CW with great
ops on both ends. On this planet, where the electronic noise has
increased by a lot more than that over the last 20 years, that's a
VERY BIG DEAL. And it's why AA7JV, a great DXpeditioner, great CW op,
and great engineer, and realizing that on multi-week expeditions, 160M
opening tended to occur on only one or two nights, developed his
system to allow simultaneous operation CW and FT8 operation on 160M.
While I've always been primarily a CW op, and have been avoiding SSB
for several years, I've been using WSJT modes for nearly 15 years for
small signal work, mostly on 6M, but also on 160M to work EU from my
QTH in NorCal, and on 60M, where the allocation is for a half-dozen
SSB channels and power is limited to 100W EIRP. I just worked DX
entity #102 on that band, loading an 80M dipole.

Apart from that, the days follow one another with more than 10,000 QSOs
per day with an almost perfect balance between CW, SSB and FT8. It looks
so surprising compared to other expeditions that some criticize us for
doing too much CW and SSB; this is a shame! We had announced for a long
time that we would prioritize “human” modes, otherwise we would not have
planned 15 operators. It would for sure be much easier to leave 6
stations
running in FT8 and enjoy long nights of sleep, the beach and 31° water,
we would already have exceeded 100,000 QSOs. But this is not the vision
we have of radio in general and especially an expedition. Given the size
of the pileups, there is obviously (and fortunately) a large majority
who must think like us.
