2024 Editor's Rating
TrustedQSL is a free software application developed by the American Radio Relay League (ARRL) that allows amateur radio operators to electronically sign and validate their logs of radio communications. The program utilizes digital certificates and public-key cryptography to ensure the authenticity of log files submitted for contest or award purposes.

TrustedQSL operates in conjunction with the Logbook of The World (LoTW), an online database maintained by ARRL that contain records of QSOs, or contacts, made between amateur radio operators. When an operator submits a log file to LoTW, they must digitally sign it using TrustedQSL. The signing process involves creating a digital signature that is unique to the file, ensuring that any subsequent changes to the log are detected.

TrustedQSL also allows operators to verify the digital signatures on logs received from other operators, ensuring that the logs have not been tampered with or falsified. This provides a level of trust and integrity for LoTW participants, who can be confident that their awards and rankings are based on valid and verifiable data.

TrustedQSL is an important tool for amateur radio operators who participate in contests or awards programs, as it enables them to securely and efficiently track their communications activities and achievements.
