The WSJT Log Viewer, version 1.0.0.10 as of 2026-08-02, is a freeware Windows application developed by Carsten Groen (OZ9AAR) for analyzing signal strengths from WSJT digital mode contacts. It processes the ALL.TXT log file generated by WSJT-X, extracting and presenting data from decoded TX and RX messages. Initially designed for EME operations on 70cm and 23cm, the software has expanded to include all HF bands, 6m, 4m, 2m, 1.25m, 70cm, 23cm, 24GHz, and 47GHz. Key features include displaying total QSOs, unique callsigns, days with activity, and signals heard, with filtering options by band and completed QSOs. The application also monitors the ALL.TXT file for live updates every two seconds, reflecting new decodes in real-time. Users can view session logs, activity charts showing daily signal counts and decoded signals, and a "Top Partners" tab listing the 25 most frequent contacts. The software provides detailed QSO information, including best received SNR and sent reports, with graphical representations of SNR over time. It supports multiple "My Callsign" entries within a single ALL.TXT file and offers a function to generate a text list of initials worked per band. The program is distributed as a single executable file, requiring no installation, and stores its configuration in a LogViewer.cfg file, allowing for different setups via command-line arguments.
