CQRLOG

Linux-based amateur radio logging software, CQRLOG, integrates a Firebird database for robust data management and offers radio control via Hamlib libraries. It provides essential features for DXers and contesters, including DX cluster connectivity, QRZ callbook lookup, a grayline map, and support for the ON6DP QSL manager database. The application incorporates a country resolution algorithm, developed by OK1RR, which is noted for its accuracy in identifying DX entities.

The software's design prioritizes operational ease and maintenance, making it suitable for active logging. Its country resolution algorithm, based on meticulously maintained country tables, aims to minimize errors in DXCC credit. The integration of Hamlib ensures compatibility with a wide array of transceivers, simplifying rig control for various operating modes and contest scenarios.
