KLog integrates with ARRL's Logbook of The World (LoTW) to upload your QSOs for confirmation and download confirmations back into your log.

Requirements

LoTW uploads/downloads are done through ARRL's TQSL (TrustedQSL) signing software, which you must install separately from https://lotw.arrl.org and configure with your LoTW certificate for your callsign.

Configuration

In Settings → Online Services (eLog), LoTW tab:

  • LoTW user — your LoTW username.
  • LoTW password.
  • Use TQSL and TQSL path — point KLog to your installed TQSL executable.
  • Select the default option for new QSOs in LoTW (e.g. whether new QSOs are queued to be sent by default).

Uploading QSOs

From Tools → LoTW tools ... (Main Menu):

  • Queue all the QSOs to be uploaded (or queue just the non-sent ones in the current log) marks QSOs for the next upload.
  • KLog calls TQSL to sign and submit the queued QSOs.
  • Mark all queued QSOs as sent to LoTW once the upload succeeds.

Downloading confirmations

Still under Tools → LoTW tools ...:

  • Download from LoTW ... — download new confirmations since your last download.
  • Download the full log from LoTW ... — download your complete confirmation history.
  • File → Import from LoTW ... (Main Menu) imports an LoTW-format report file directly, if you downloaded it manually from the LoTW website instead.

Downloaded confirmations update the LoTW Sent / LoTW Rec status and dates shown in the QSO's LoTW tab (see Entering a QSO) and feed the Awards and Statistics confirmed counts.
