Receive QSOs over UDP from Decodium, WSJT-X and JTDX, with ADIF import and export.
A local SQLite database, filters, change history and backup tools for your activity.
Maps, statistics, awards and QSL integrations with LoTW, QRZ Logbook and eQSL.
Features, integrations and operating conditions, with direct links to project sources.
The connection guideA local SQLite database, ADIF import/export and CSV/N1MM imports. Organise QSOs with tags and filters, edit records in batches and recover revisions or deleted contacts. Duplicate checks and backups help keep your log in order.
Source & documentationQRZ XML and HamQTH complement your contact history. DX Cluster, RBN, HamAlert and POTA put spots in the context of your log. Filters, alerts and explained priorities help identify new entities, bands and modes, using the available data.
Source & documentationUpload to configured services: LoTW, eQSL, QRZ Logbook, Club Log and Wavelog. Download supported confirmations, organise bureau and direct delivery, and create PDF labels or custom PDF/PNG cards. External service accounts are required; LoTW uses TQSL.
Source & documentationTrack award progress and applications, prepare POTA/SOTA/WWFF/IOTA sessions and manage contests with duplicate checks, serial numbers and Cabrillo 3.0. Contest scoring and export follow the verified rules catalogue. Official award credit remains the responsibility of the issuing organisations.
Source & documentationCAT profiles, CW macros and keyer, the ggmorse decoder and DecoRotor/rotctld pointing connect your log to the station. Controls depend on equipment and backend. The optional CTC neural decoder requires an ONNX-enabled build and is absent from standard binaries.
Source & documentationOptional Cloud synchronisation carries QSOs, profiles and portable preferences. Ports, paths and device settings stay local. With the service configured, you can access web views and share logs with separate roles; the local database continues to work offline.
Source & documentationA shared passion, different skills.
A project that grows through contributions.
