Our club have got call OG60F, anniversary our clubs OH1AF
60 years being and we have possibility use it whole this year.
Now, it would be nice to make FT8 qsos with this call also.
What I have tried, it's only possible with free text.
What I know, OG is one of OH prefixes, as well as OJ, OI and OF.
Why these are not included as wsjt-x prefixes?
Is there any way to use it as "normal"?

Hi Jarmo,
the problem is not with the OG part of the prefix, it is the combination
of two letters *and* two numbers that is not covered by the WSJT
protocols. There are some thoughts on a new protocol that might allow
for a much larger set of possible callsigns but, if it were implemented,
it will not be "back fitted" to existing protocols as it necessarily
requires more payload bits and in turn one or more of longer transmit
times, wider signal bandwidths, or lower decoding sensitivity.
So in short, you are restricted to free text messages with that
callsign, and I doubt it will be very successful.
