I checked my log and found the same issue. I download from LOTW regularly and have no reason to believe that I was not in their log (especially three times on the same day -- 20, 15, and 10M).
Didn't realize the Qs weren't QSLd as I have already confirmed 3X on those bands. Hummmmmmmm???!!!???? AD1C, any idea what's going on with this???? 73, Karl, K1KO Virginia Beach
