Hi Rick,
Yes, I THINK I will be OK using the callsign of TO7GJ for both FT8 and Q65-60A modes,
but it sure will be interesting to hear definitively from Joe as to whether I will
suffer in any way by not having "TO" in the list of official "Type 1" prefixes.

Lance,
WSJT-X modes with 77-bit message payloads (FST4, FT4, FT8, MSK144, and Q65) can
handle QSOs between a standard and a compound/nonstandard call.
WSJT-X modes with 72-bit message payloads (JT4, JT9, JT65) have a much more
restrictive set of rules. The documentation has separate sections for those two
message payload lengths… I found it easy to get lost in the discussion of the
72-bit payloads, which apply to modes you might not be using.
Note that the comment about the table of prefixes and suffixes is contained in the
72-bit section, not the 77-bit section.
So… I would suggest that if you have a Type 1 callsign and use the modes with
77-bit message payloads, you should not have a problem working stations with
compound/nonstandard calls as long as they are using a current version of WSJT-X,
or some other software that is ‘compatible’.
As we all understand, the latest version of WSJT-X is compatible with another copy
of the latest version of WSJT-X…. HOWEVER… You, as the dxpedition station, can’t
guarantee compatibility with any other software… and callers using other software
are ‘on their own’. Kinda ugly when you put it that way, but it is the same as
saying ‘Our SSB QSOs will use English’ and having stations expect you to be able to
understand Farsi, or Swahili, or French (LOL).
The ‘gotcha’ with 77-bit messages and compound/nonstandard callsigns really only
gets involved if the station with the compound/nonstandard call is calling CQ.
In that case, the CQ message does not include the CQ caller’s grid.
However(!) with 77-bit messages and non-compound/standard callsigns (like what Joe
suggested, and what I think you will be using) CQ is not a problem
The CQ message for a non-compound/standard callsign DOES include the CQ
caller’s grid.
It will be interesting to see the ‘official’ response from Joe.
