    You don't have to have a key to complete a CW contact. Many people use software to send (and sometimes decode) CW; particularly "canned" contest exchanges.

    I noticed this in my LoTW account

    I noticed the 'QSL' timestamp on my contact is almost identical to the 'Received' timestamp on yours. So that suggests I2SVA submitted a large batch of old logs to LoTW on 2011-01-21. That means probably you submitted a log with the matching contact on 2021-07-10.

    If you log in to your LoTW account, and go to 'Your Account', then select 'Your Activity', it will show you the dates and times that you submitted signed logs. You will probably find one on 2021-07-10.
    I you click on the blue highlighted 'Result', it will show the name of the tq8 file you submitted, like this.

    If you can find the ADIF or Cabrillo file you submitted at that time (ADIF or '.adi' file may be in the same folder as the '.tq8' file), you should be able to see if there is a CW contact with I2SVA.

    My guess is that you tried something in 1999 WPX as a "one-off" experiment, then forgot about it during the subsequent 22 years.

    I think LoTW is a pretty cool system. :cool:

    So yours was I2SVA too. Hmmm. Did you in fact work and log I2SVA?

    Yes, I did.

    The contact is from the 2006 ARRL International DX Contest CW.

    I have a QSO from the same weekend and agree with your assessment - I2SVA did a big batch upload:

    So, uploaded my ARRL DX log from 2006 on March 27, 2006, and I2SVA loaded his log on January 21, 2011 creating a "match".

    What mode did you have for your QSO that you uploaded? Was there a mode listed at all? Does LoTW default to CW if no mode is in the database? Curious!

    Well I really won't worry about it, but you heard it here that I had better re-learn code. So I guess I better get my butt in the chair and hook up the keyer. Also I have listened to code and decoded it on the computer, lets say I don't get a good result. So learning that way won't work. Works good for RTTY and other digital modes

    What I have to say shouldn't concern you. Put me on ignore or quit whining, those are the choices you have to save face.

    Kick away the crutches and take off the training wheels. I hope you are following Martin-G3EDM's thread. He's working CW under terrible cndx and barely copying but that's how you get there! The number of hours he is putting into the effort don't go unnoticed.
    I think many of us are vicariously reliving our early experiences thru his posts.
