Hi All,

some time back the message generation was changed to help those with 
type 2 compound call signs. Details are here:

https://sourceforge.net/p/wsjt/mailman/message/32950792/

I am re-visiting this as John TI4/N0URE points out that there is no 
generated message to send the first report in his case.

I think the intention was to send the full type 2 compound call sign at 
the first practical opportunity. When calling CQ the full call is 
encoded along with the 73 message 5. This is fine but having message 2 as:

DE TI4/N0URE EK70

doesn't seem to make sense since this is where the first report should 
be sent, in fact as this is normally a transmission by initial caller, 
they have already called CQ with their full compound call sign. So I 
believe message 2 should be like:

G4WJS N0URE -15

and message 3, which is the first opportunity for the replying station 
to give their full compound call sign, should be like:

DE TI4/N0URE R-05

Summarizing for a caller with a type 2 compound call sign:

CQ TI4/N0URE EK70
                                        N0URE G4WJS IO91
G4WJS N0URE -05
                                        N0URE G4WJS R-15
G4WJS N0URE RRR
                                        N0URE G4WJS 73     (Also see below)
DE TI4/N0URE 73

and for an answerer with a type 2 compound call sign:

CQ G4WJS IO91
                                          N0URE G4WJS EK70
N0URE G4WJS -15
                                          DE TI4/N0URE R-05
N0URE G4WJS RRR
                                          DE TI4/N0URE 73
N0URE G4WJS 73                                              (Also see below)

with both ends having type 2 compound call signs:

CQ TI4/N0URE EK70
                                           N0URE W9XYZ FN75
W9XYZ N0URE +05
                                           DE W9XYZ/VE1 R+02
W9XYZ N0URE RRR
                                           DE W9XYZ/VE1 73
DE TI4/N0URE 73

Also related to this, it seems to me that when having a QSO with a 
compound call sign station, type 1 and type 2 compound call signs should 
be treated the same in generated messages and the only time the full 
compound call sign need be used is in message 5 e.g.

W9XYZ/VE1 73

or

TI4/N0URE 73

thus confirming that you are aware you have worked a compound call sign 
station.

So a QSO might proceed as follows:

CQ G4WJS IO91
                                    G4WJS W9XYZ FN75
W9XYZ G4WJS -10
                                    DE W9XYZ/VE1 R-12
W9XYZ G4WJS RRR
                                     DE W9XYZ/VE1 73
W9XYZ/VE1 73

or

CQ W9XYZ/VE1 FN75
                                          W9XYZ G4WJS IO91
G4WJS W9XYZ -12
                                           W9XYZ G4WJS R-10
G4WJS W9XYZ RRR
                                           W9XYZ/VE1 73
DE W9XYZ/VE1 73

I also propose that the DX Call widget should not be overwritten with a 
base call of a compound call sign e.g. if you double click on:

CQ W9XYZ/VE1 FN74

and later in the QSO double click on:

G4WJS W9XYZ -12

the DX Call shall remain as W9XYZ/VE1 so that message generation still 
treats it as a compound call sign and logging saves the correct call sign.

I also propose that a very basic check on the call sign extracted when 
double clicking a decoded message be applied to validate if it is a call 
sign and not DX or TU or 73 or FRED or RRR or ...

The check will be that the call sign must contain at least one letter 
and one number next to each other. Not perfect but will not suffer false 
positives and will catch almost all misinterpretations of the second 
word in free text messages.

Here is an implementation of what I propose:

I would appreciate comments and testing please. Mac and Linux versions 
on request.
