[Dx4win] Complex Log merge question -- help requested.

[K7ZO (Scott Tuthill)]

As the QSL manager for the NK7U contest station I maintain a DX4WIN log of
over 130,00 QSO's. I keep a copy of the log and DX4WIN at my QTH and NK7U
does as well at his. Since the last time we sync'd the log file up NK7U and
I have both added QSOs to the log as well as added QSL confirmations for
past QSO's -- and these changes are totally different. So, now we we have
two copies of the log that are different in both QSO's and and QSL
confirmations.

My question is how can I get these two logs sync'd back up into one master
log? We are using 5.03.

Getting the new QSO's sync'd up is easy. Just merge one log into the other
"Ignoring Duplicate QSOs". The problem is with the QSL confirmations. If I
copy one log into the other with "Duplicate QSO replaces existing one" the
QSL confirmations in the log being merged into will be "erased" since when
the duplicate QSO replaces the existing one it does not have the QSL
Confirmation. Yes, we could merge the new QSO's and go back in and update
the QSL's by hand in the merged log, but we are talking about 500 QSL's that
would need to be re-entered.

Anyone got any ideas?

The notes to Version 6.03 describe the following functionality: "Import
(merge) can use imported QSO for confirmation only (we can set confirmed or
upload confirmed". From the description I am not sure if this is solves the
problem, but it looks hopefull. Does anyone have any experience with this
function? If it does I would gladly pay to upgrade to 6.03.

Or, does anyone know the DX4WIN file format? I might be able to write a
separate merge program.

Thanks for your advice and assistance.
