About
Trusted QSL (TQSL) is ARRL's software for Apple Mac computers, available alongside versions for MS Windows and Linux. The current release is version 2.8.7. A 64-bit build supports Intel and Apple Silicon processors. A legacy 32-bit universal binary supports PPC and Intel processors on OS X 10.4 (Tiger) and later.
The software is distributed from ARRL's TQSL Download page, which sits within the Logbook of The World section of the ARRL website. Release notes for v2.8.7 are published there as well. You do not need to uninstall older versions of TQSL before installing the new one.
The website text does not describe the app's specific features beyond these platform and download details. For help, the site links to LoTW Help, a Quick Start guide, and a Developer resource.
