Just heard from the 5K0T QSL manager regarding the sat logs...
"Was a wrong set time in the pc. I corrected all Sats log.
I´ll upload the log to LoTW next year, after it be clear.
Also upload fast the OQRS and Direct asked QSL."
Should be good to go... of course, your mileage may vary. =^) If you have any more problems, suggest you check with their QSL manager. 73, N4UFO
