Randy, Thank you for this explanation, which makes perfect sense. <duh - why didn't I think of that?> If the other stations are re-submitting the same QSOs, then it's possible that those 20 "unaccounted for" QSOs had been confirmed via an earlier download and won't be reconfirmed.
Maybe I'll perform another download in a few days, when I haven't just run a contest. The LoTW download file should be small enough that I can easily compare every downloaded QSO and see what's happening. Examining this download with 294 QSOs in it only made my head hurt! ;-) -larry K8UT ----- Original Message ----- From: "Randy Farmer" <[email protected]> To: "Larry Gauthier (K8UT)" <[email protected]>; "DX4Win Reflector" <[email protected]> Sent: Friday, January 30, 2009 21:48 Subject: Re: [Dx4win] Measuring the LoTW import process > >>Today I downloaded an LoTW report from the ARRL web site and imported the >>files into my DX4Win log.
