Trusted QSL for Mac

Quick summary

Trusted QSL is a no-cost macOS utility that helps amateur radio operators prepare and submit QSO entries to the ARRL Logbook of The World (LoTW). It simplifies creating the files required for LoTW uploads and reduces the manual steps involved in signing and sending QSO records, while keeping logs compliant with LoTW expectations.

Primary benefits

• Works with a wide range of logging file types, so it integrates with many popular logging programs.
• Produces secure digital signatures for QSO records prior to upload, improving the integrity of submitted logs.
• Offers a straightforward interface and workflow that streamlines signing and uploading to LoTW, making log management faster and less error-prone.

How it helps operators

Trusted QSL automates the creation of the signed files LoTW requires, removing the need to sign each QSO entry manually. Users can import their log exports, apply the digital signature, and upload the resulting package to LoTW. This both speeds up the submission process and helps ensure records meet LoTW’s format and security requirements.

Alternative option

A commonly mentioned free alternative is MeshLab. If you’re evaluating other tools, double-check that any alternative supports LoTW-compatible signing and the logging formats you use, since some programs focus on different tasks and may not provide the same upload/signing features.
