Club Log is a web-based log analysis platform for amateur radio operators. After users upload their radio contact logs, the system uses global log data to provide personal DXCC reports, leaderboards, grid and zone charts, activity timelines, log search, Most Wanted trends, propagation predictions, and more. It is not a general-purpose developer tool, but a highly specialized amateur radio data and analytics infrastructure.
In terms of features, Club Log covers log analysis, HF/satellite mode statistics, DX Cluster filtering, QSL recommendations, OQRS online QSL requests, Log Matching, ADIF Diff, LoTW Sync, DX Report, and expedition tools. Expedition teams can use charts, statistics, log search, QSL, fundraising, and Live Streams. The source text also notes that its callsign definitions and raw data are open to the community and support the callsign logic used by most logging software, giving it strong foundational data value within the amateur radio software ecosystem.
Club Log allows users to link log searches to personal websites or QRZ profiles, and its documentation states that it can be integrated into websites or software. However, the source text does not clearly list an API, SDK, authentication method, rate limits, or sample code. For developers, this means there is integration potential, but the maturity of the interfaces needs to be verified in the official documentation. Supported languages, frameworks, open-source status, and self-hosting options are not disclosed.
The platform is described as a free DXing resource and provides a Donate option. No subscription plans or paid features are mentioned. For support, Club Log offers a Helpdesk, a Discord community, and a support email address, with the helpdesk maintained by multiple volunteers. For a free community project, its support resources are fairly complete, but there is no information about commercial SLAs or enterprise-grade guarantees.
Its main strength is the scale of its data: the source text shows around 86,449 users, 135,815 callsigns, and 1.35 billion log records. Its feature set also spans the full workflow from log analysis to QSL and expedition operations. The downsides are that its use case is extremely vertical, with limited value for non-radio users, and there is insufficient information about APIs, self-hosting, open source, and payments. It is best suited for DXers, amateur radio clubs, expedition teams, and software authors who need callsign or log data integration.
The crawled text does not provide information about access from mainland China, network connectivity, payment methods, or local alternatives, so this remains unknown. If access from China is unstable, LoTW, eQSL, QRZ Logbook, HamQTH, or local logging software may be considered as supplements, but actual availability still needs to be tested.
