Reino,
Matt's query is abut WSPR mode, there are no CQ calls and the structured
messages are much simpler since they are beacon transmissions. The
handling of non-standard calls is also different from QSO modes.

Hi Matt,
You should be possible to send CQ message without grid square locator
and make contacts with the help on hashed call sign using automatic
message generation. There strong limits what can be included into a
single message, when the basic call sign is 7 characters long. As a
workaround you could use free text messages for your grid square
locator such as ‘VK3FDLL AB12’ or ‘AB12 VK3FDLL’ and broadcast that
message now and then, or send as the last message of a QSO ‘LOC AB12
73’. Other station can see that is belongs to you from the frequency.
That kind of method is used in the EU VHF contest messages as a part
of the protocol. Note that free text maximum is 13 characters
including space characters.

Hi there,
I'm using WSJT-X (WSPR Mode) for quite a while for receiving and now
I've attempted to transmit.
I am a Foundation Licence holder in Australia (VK), which means I have
a 7 digit callsign - VK3FDLL
With various tests, I can hear my WSPR transmissions away from my
station and WSJT-X can even decode my transmissions. However the
decoding only occurs on transmissions where my callsign is hashed
(Type 3 message, I believe?)
Transmissions where my full, 7 digit callsign (and 4 digit grid square
locator) is transmitted are not decoded by WSJT-X
Are you able to point me in the right direction as to how I can
achieve being decoded correctly? Or does the software and/or protocol
simply don't support a 7 digit callsign?
Regards,
Matthew Jones - VK3FDLL
