CQRLOG is an amateur radio logging application designed to assist radio operators with contact logging, contesting, and station management. It provides a graphical user interface for manual entry and automated capture from transceivers and rotators while supporting integration with mapping, database, and digital mode tools. The project draws on contributions and interoperability with many projects and organizations in the amateur radio and open source ecosystems.
CQRLOG functions as a logging and station management tool used by operators active in contests such as the IARU HF World Championship, ARRL Field Day, CQ World Wide DX Contest and events like the Worked All Europe awards. It offers DX cluster connectivity compatible with networks such as the DX Summit and supports synchronization with repositories like QRZ.com, HamQTH, eQSL, LoTW and services run by organizations such as the American Radio Relay League, Radio Amateurs of Canada and the RSGB. CQRLOG's interface integrates mapping and rotor control that can interoperate with projects including Google Maps, OpenStreetMap, GRASS GIS and hardware controllers used by stations allied with groups like AMSAT and ARRL DXCC. It is widely used by operators who participate in events organized by societies such as the Fédération Internationale de l'Automobile (note: contest sponsorship contexts) and exchanges data with databases maintained by institutions like the Smithsonian Institution for historical logging studies.
CQRLOG provides core logging features comparable to other packages like Ham Radio Deluxe, N1MM Logger+, TR4W and DXLab Suite. Standard features include contact entry fields referencing callsign registries maintained by ITU member administrations, automatic band and mode detection used in operations involving equipment from vendors such as Icom, Yaesu, Kenwood, Elecraft and FlexRadio Systems, and rotator control compatible with hardware from Green Heron Engineering, Yaesu and Dino-style interfaces. It supports ADIF and Cabrillo export formats used in exchanges recognized by events such as CQ WPX and WRTC, and includes real-time cluster spotting using protocols adopted by networks like Packet Radio hubs and servers operated by groups including DX Cluster nodes hosted at institutions such as MIT and Stanford University. Logging automation interfaces enable interaction with digital-mode software like WSJT-X, FLdigi, Fldigi, MMSSTV and packet utilities maintained in projects affiliated with Debian, Fedora Project and Ubuntu.
Development began as a community-driven effort influenced by earlier logging projects and open-source toolchains prominent in communities around organizations such as The Linux Foundation, Free Software Foundation and distributions like Debian. Contributions have come from operators and developers active in forums run by entities such as QRZ.com, Reddit subcommunities, and regional societies including the German Amateur Radio Club (DARC) and Istituto Italiano di Ricerca-adjacent groups. Over time, feature expansion paralleled advancements in transceiver remote control protocols developed by manufacturers including Icom Inc., Yaesu Musen, Kenwood Corporation and software-defined radio research at institutions like MIT Lincoln Laboratory and Ohio State University.
CQRLOG is typically packaged for Unix-like systems and distributions such as Ubuntu, Debian, Fedora and openSUSE, and it can run on hardware platforms produced by manufacturers including Intel, AMD, ARM-based vendors and single-board computers such as Raspberry Pi. It relies on libraries and runtimes provided by projects like GTK, Qt Project (for optional front-ends), PostgreSQL, SQLite and toolchains from GCC or Clang. Integration with serial and USB devices requires support from subsystems developed by operating system vendors such as Red Hat and Canonical.
CQRLOG supports interoperability with catalog and callbook services like QRZ.com, HamQTH, and global authentication systems such as Logbook of The World (LoTW) administered by the American Radio Relay League. It exchanges data using ADIF and Cabrillo standards endorsed by contest organizers like CQ Amateur Radio and interoperates with mapping projects such as OpenStreetMap and commercial services like Google Maps for station plotting. Radio control implementations follow protocol conventions established by manufacturers including Icom, Yaesu, Kenwood and SDR interfaces used by projects like GNU Radio and hardware platforms produced by Ettus Research and FlexRadio Systems.
The user base comprises amateur radio operators, contesters, DXpedition teams, and club stations affiliated with organizations such as the American Radio Relay League, Radio Society of Great Britain, International Amateur Radio Union and regional clubs including DARC and RSGB. Community support is mediated via mailing lists, forums hosted on platforms run by Stack Exchange networks, social groups on services offered by Facebook and development discussions on repositories hosted by organizations such as GitHub and SourceForge. Educational and archival use is evident in collaborations with museums and archives like the Smithsonian Institution and university amateur radio clubs at MIT, Stanford University and University of Cambridge.
CQRLOG is distributed under open-source licensing consistent with repositories managed by communities such as Debian and Fedora Project and is available through package managers provided by vendors like Canonical and Red Hat. Source code distribution, contribution workflows and issue tracking commonly use platforms maintained by organizations including GitHub, GitLab and SourceForge; these workflows follow contribution models advocated by the Free Software Foundation and standards used in projects supported by The Linux Foundation. Packaging for specific distributions adheres to policies from maintainers at Debian Project and Fedora Project.
