Hi all, With code revision 7289 I have implemented support for messages of the form "CQ AA" through "CQ ZZ". They are encoded by sending "E9AA" through "E9ZZ" for the first callsign. Upon reception these calls are converted back to the form "CQ AA" through "CQ ZZ". For consistency, "CQ DX" is still encoded as "CQ9DX". Some confusion will necessarily arise because users of older versions of software will start to see callsigns like "E9EU", "E9NA", "CQ VT", etc., on their screens. Of course, in principle users who have not upgraded their software can do some mental translations to make QSOs with stations using the new feature. Such users should interpret a received "E9xx" as "CQ xx". To call "CQ xx" they can send "E9xx <MyCall> <MyGrid>". But at the time of our next release, we should strongly encourage users to upgrade. It's likely that some users who are building WSJT-X for themselves, using source code in our development branch, will start using the new feature before any wider announcement is made. Be on the lookout for queries about strange 4-character callsigns "E9AA" through "E9ZZ". -- 73, Joe, K1JT
