There was a discussion in a Google group about valid prefixes and suffixes that

in JT65 - and by the JT65-HB9HQX software.

'jt65code.exe -t' lists all possible variations. Prefix 'A000' to 'ZZZZ' should 
be possible
and they will work by testing them with jt65code.exe.

Valid prefixes are listed in 
thehttp://physics.princeton.edu/pulsar/K1JT/JT65.pdf  document,
some 4 char prefixes starting with a digit, or for example, per list 'VK9M' 
showing
other results with jt65code.exe and tested in WSJT-X 1.7 devel 8164

But "CQ 3D3R/OE1MWW RH97" results in "CQ 3D3R/OE1MWW" the QRA locator is 
missing.

If I just change it to "CQ AD3R/OE1MWW RH97" or "CQ ZD3R/OE1MWW RH97" it will 
be sent
as typed. Otherwise, the listed VK9M in the JT65.pdf, using it with 
jt65code.exe gives
me instead of "CQ VK9M/OE1MWW JN88" just "CQ VK9M/OE1MWW", the QRA locator is 
missing in
this case. Replacing the '9' with an 'Z' for testing, will be coded as typed.

All this is not important at the moment, just, which guideline should be used?

Hi Wolfgang,

there are two different types of compound calls supported in WSJT-X, type 1 which use the predefined suffixes and prefixes that are shown in the help menu and newer type 2 compound calls that support a wider range of prefixes and suffixes limited by format rather to a predefined list. Both types have limitations on the messages that can be sent. Type 1 cannot be sent with grid squares in CQ/QRZ and TX1 messages but do include both full callsigns in those message types. Type 2 compound callsigns can send a grid and full callsign in a CQ/QRZ message but cannot send a full callsign with another callsign in other message types, instead having to send the base callsign only or a DE <full-callsign> message with a report, R+report or 73 message. The User Guide contains examples of QSOs with both types of compound callsign.
