Save QSO
Clicking on the log button allows you to log a QSO with a looked up callsign. The Save QSO button will log a ADIF entry on the local file system with most of the information prefilled in. The log screen allows you to add additional QSO fields to the log entry.

Upload to Logging Service
Clicking the Upload ADIF button will take you to a new screen, allowing you to upload log files to LoTW or Cloudlog. With the logging provider(s) selected clicking the Upload button will upload the selected local ADIF file to logging provider(s). Duplicate QSOs are handled by the logging providers automatically.
A new local log file is created with the current timestamp each time the program is started and a new log record created. Create a new local log file by clicking the Create New Log button.

Configuration
The LoTW upload requires you to install and configure TQSL on your local machine.
