Perhaps it's just my memory failing or me not reading enough posts here but I see that I have a lot of "C" in the DXView matrix for QSO that are fully verified on LoTW. The QSO in question show up as "Card QSL" in LoTW although that I am positive I have received LoTW confirmations for before applying for credits.
Also, clicking "update from lotw" just reports the QSO as "accepted and confirmed" although they are fully verified in my DXCC challenge account.
Could this be a side effect of the "emergency repair" done last spring, perhaps?
+ Are you referring to the ARRL's "system disruption" caused by its failure to maintain immutable backups and a tested disaster recovery plan? If so, no one knows what changes were made. What is known is that the same developer who released LoTW in 2003 with little testing and no end-user documentation has been making changes.
