Ed,

The last time I used MixW in the CQ WW RTTY was in 2002 as VE3IAY, but I 
still use it for PSK31 and for testing, and I am familiar enough with it 
to be fairly certain where these problems originate.

MixW does have Cabrillo export capability. It does not automatically 
select the appropriate Cabrillo format based on the contest; the user 
has to know enough to select the "CQ/RJ WW RTTY" format. This is one 
possible source of errors. You can identify logs from people who 
selected the wrong format by the fact that there will be no "DX" in the 
exchange for non-W/VE contacts.

However, I believe that the biggest source of bad Cabrillo files from 
MixW results from users who do not know how to log contacts for this 
contest. In order for the Cabrillo export to work properly, the received 
exchange information for this contest *must* be logged in three separate 
fields: RST_recvd, Exch_recvd (this is where the CQ zone is logged) and 
Domain (the Domain is where the W/VE state/province must be logged). 
There is also a QTH field in MixW, but that is not used in this contest; 
the state/province must be logged in Domain, not in QTH, and not 
combined with the zone in the Exch_recvd field.

I don't believe this is documented anywhere in the Help files. As far as 
I can see users have to figure this out by trial and error. The default 
screen entry windows both for contests and for normal logging do not 
display the Domain field; users have to customize the log display to 
make this field visible, and it is very important that this field be 
visible during contests that use the Domain field because of MixW's 
auto-entry feature (see below).

I'd be willing to bet that the majority of MixW users didn't realize 
this, and simply logged the received zone and state/province both in the 
Exch_recvd field. The way the Cabrillo export works, this can result in 
a variety of different outputs, even within the same file.

If the user logged the two exchange fields without any intervening 
spaces they will both appear in the Cabrillo file exactly as entered, 
with no space between them. If the exchange field was three or fewer 
characters long there will also be a "DX" field added to the Cabrillo 
file, but if the field contains four or more characters, there will not 
be a "DX"; the state/province/DX column will simply be missing. The 
log-checking software may record it as 0, since MixW always adds a tx_id 
column even when it is not necessary.

If the user put a space between the two exchange fields in the 
Exch_recvd field, only the first one will be in the Cabrillo file 
(everything after the space is discarded). There will be a "DX" added 
after the first one, regardless of whether it was a zone or a state. 
Either the QTH or the zone will be missing, depending on the order in 
which they were entered.

If the user entered some other delimiter such as a dash or slash, the 
entire combination including the delimiter will appear in the Cabrillo 
file's zone column, and the state/province/DX column will be missing.

One other unusual feature of MixW: It tries to pick up exchange elements 
automatically from the input stream; two-letter combinations surrounded 
by spaces that happen to match a state abbreviation can be picked up by 
the program and auto-entered into the Domain field. Under certain 
conditions, state information from QSOs with the same station logged 
before the contest may also be automatically inserted into the contest 
log. This means that sometimes there may actually be something in the 
Domain field in the log even though the user didn't enter it. If the 
Domain field was not displayed in the log window, the user will not even 
be aware that this has happened. However, whatever was placed in the 
Domain field will show up in the Cabrillo file, so sometimes this column 
may contain something despite the fact that the user was not entering 
the exchange elements into the correct fields.

As for the ADIF files, the entire received exchange will be exported 
using the SRX tag, unless it contained a space. If there was a space 
entered into the exchange field, the part of the logged exchange before 
the space will be tagged with SRX and the part after the space will be 
tagged with SRX_STRING. The information, if any, logged in the Domain 
field will be output with the STATE tag.

Users can fix their logs after the contest, but it's not very easy. They 
will have to call up the edit dialog for each QSO, check the Domain 
field for incorrect automatically-entered data and remove it, and for 
W/VE contacts remove the state/province from the Exch_recvd field and 
copy it into the Domain field. Most people will probably find it easier 
to edit the Cabrillo file with a text editor.

As for advising submitters what to do:

(1) Before the contest, tell them how to log contacts with MixW (i.e. 
tell them that they must log the zone and state/province in the 
Exch_recvd and Domain fields respectively, and that they will have to 
create a custom log bar layout in order to display the Domain field).

(2) After the contest, advise them that they must check their Cabrillo 
log carefully before submitting it, looking for the following:

(a) all contacts with non-W/VE stations must have DX in the QTH column 
(almost at the right end of each QSO line, followed by a 0 for the 
tx_id); if this is missing, they should go back and re-export using the 
CQ/RJ WW RTTY Cabrillo format;

(b) all contacts with W/VE stations must have both the zone and the 
state/province, in that order, separated by a space, following the 
received RST near the right end of each QSO line; if in any of the QSO 
lines the space is missing, or if one of the elements is missing or they 
are in the wrong order, or if there is an extra "DX", they must edit the 
Cabrillo file by hand to correct the problem.
