Although Alex's idea of speeding up DXpedition QSOs using is a great one, how
would the caller's software recognize that the 73 was directed to his station?
Neither the caller just worked or DX station's call would be contained in the
"73" line which starts a QSO with the next station. It appears that, as it is
now done for CW QSOs with DXpeditions, it would require manual intervention by
the station being worked to stop further transmissions after the "73" message
was received.
However, might I suggest the following idea:
All callers would start with the "Tx2" message (Calls and report).
During each of the DXpedition station's 15 sequences, it would respond with,
for example:
"W3LPL +30 VK9MMM RR73"
Next, many callers call VK9MMM and hearing K1JT, VK9MMM would respond with:
"K1JT +20 VK9MMM RR73"
more callers call VK9MMM and hearing VE3NEA he responds with:
"VE3NEA +10 VK9MMM RR73"
Etc, etc, etc. until the pileup is worked. As long as there is a never ending
line of callers, the DXpedition could maintain a maximum QSO rate of 120 per
hour.
The caller's software, recognizing both his and the DXpedition's call signs
plus the "RR73" would stop further transmissions, as no more would be required.
What say WSJT-X software specialists? Can do?

FT8 IS GREAT!!!

FT8 differs from the traditional modes in one important way: multiple signal
decoding. This opens a possibility to significantly
increase the speed of a pileup QSO by using a shortened QSO sequence. Here is
one possibility that would increase the QSO rate
up to 120/hour:
CQ VK9MMM QH72
VK9MMM VE3NEA FN03, VK9MMM K1JT FN20, VK9MMM W3LPL FM19
-------------------
W3LPL VK9MMM +30
VK9MM W3LPL -20
-------------------
73 NOW K1JT +20
VK9MM K1JT -20
-------------------
73 NOW VE3NEA +10
VK9MM VE3NEA -20
-------------------
73 CQ VK9MMM QH72
...
This would require a new message, "73 NOW...", in addition to already defined
"CQ...", "CQ DX...", etc. Another message, "73
CQ...", would also save some redundant transmissions by confirming the current
QSO and requesting new calls at the same time.
