[Dx4win] QSO time issues when importing

[Paul van der Eijk]

Dave,

When you have the QSO start-time in an ADIF record Dx4win will use that
time. If that field is missing, it will use the end-time. So I’m guessing
some ADIF producer is changing the values of those fields or does not
export the start-time.
That should be easy to verify.
