About
ClubLog is a comprehensive online platform built for the global amateur radio community, offering a rich suite of tools to help operators manage, analyze, and compare their contact logs. Founded by Michael Wells (G7VJR), it serves as a central hub where ham radio enthusiasts can upload ADIF log files, track worked DXCC entities, and measure their progress against other operators through detailed league tables and challenge systems. Key capabilities include DXCC and Satellite league charts, Zone and Grid Square charts, log inspection, and log matching to verify contacts. The Most Wanted lists help operators identify rare entities they have yet to work, while the DXCC Analysis tool provides deep insight into entity statistics. ClubLog also supports OQRS (Online QSL Request System) for managing QSL card requests and features LoTW (Logbook of the World) synchronization for confirmed contacts. Additional tools cover propagation analysis, an ADIF diff utility, a DX Cluster log search, a callsign tester, and locator/map tools. Expedition teams frequently use ClubLog to publish their logs in real time during activations, and listeners can follow along via integrated livestreams. The platform is free to use and sustained by community donations, making it accessible to amateur radio operators worldwide regardless of experience level.
