American Radio Relay League

The American Radio Relay League, the national association for amateur radio in the United States, offers Trusted QSL, a compact open-source suite that lets licensed operators cryptographically sign and exchange confirmation data for on-air contacts. Built around the Logbook of the World system, the software reads standard ADIF log files, applies digital signatures, and uploads the resulting “QSO records” to ARRL servers so hams can pursue awards such as DX Century Club or Worked All States without mailing paper cards. Trusted QSL also verifies incoming confirmations, merges them into local logs, and exports reports in formats accepted by contest and award sponsors worldwide. Typical use cases include daily logging for HF and VHF operators, contest expeditions that need rapid bulk uploads, and award applicants who must prove band-mode-country combinations. Because the code is open, developers embed its libraries in third-party logging applications, while individual amateurs run the graphical or command-line tools on Windows, macOS, or Linux to keep their station records synchronized with the global LoTW database. The American Radio Relay League’s Trusted QSL software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the latest release, and can be queued alongside other applications for unattended batch installation.
