The HAMLOG cloud service was launched in 2015. The prototype was an online logging system for the RAEM-110 memorial event. The system allowed special event stations to upload their QSOs to a central database and then issue electronic certificates to all participants based on the uploaded QSO data.

Traditional amateur radio award programs use manual QSO/QSL verification, which places a significant burden on both applicants and award sponsors. The ARRL pioneered electronic QSO matching with its successful Logbook of the World project, which revolutionized the award management process. However, its architecture has several limitations, such as lacking scalability and flexibility. The need for an agile platform capable of supporting thousands of different award programs and special events was clear. That's why the HAMLOG.ONLINE platform was born.

Initially, the Hamlog platform allowed users to upload ADIF files and issue electronic awards based on the presence of QSOs in special event station logs. Later, QSO matching was added. A lot of focus was put on giving award sponsors the ability to set up their own awards. In just a few years, the number of award programs hosted on the platform exceeded 2,000.

Alongside short-term special event awards, which didn't require extensive security measures, several national organizations chose to host their awards on the platform. These programs needed a high level of system reliability, availability, and security. Today, the platform uses distributed data processing with a strong focus on protecting user accounts.

The platform proved to be capable of not only supporting awards and checking uploaded QSOs but also providing real-time logging. Each QSO can be recorded as soon as it's completed, with nearly real-time recalculation of award standings. QSOs can be added directly in the web browser, and some loggers, like WSJT-X, seamlessly integrate with Hamlog. This means operators don't need to re-enter QSO data or upload files. Once a QSO is completed, it goes straight to the online log, and operators receive award credits immediately, provided that the other operators use Hamlog's real-time logging or upload their logs promptly.

For awards that accept Logbook of the World (LotW) confirmations, Hamlog allows the import of LotW QSL data.

The system allows operators to create, send, and receive electronic QSLs with their own designs. HAMLOG can also be used as a cloud backup, capable of storing all your QSOs ever made.

The platform is supported by sponsors and ad revenue, making it free for all operators and award sponsors. Donations are always welcome, and sponsorship packages are available. Donors can make contributions through their accounts. For information about sponsorship packages, please contact us at infohamlog.online.

Hamlog is an actively developing project supported by volunteers from many countries. We believe it can become an integrated platform that simplifies routine tasks for operators, sparks interest in new activities and modes, and adds more fun to our great hobby.
