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.

Spothole aggregates real-time amateur radio spots from various sources, including traditional **DX clusters** and specialized outdoor activity programs like POTA and SOTA. The platform provides a highly customizable web interface where users can configure display options such as DX and DE continents, local time, and a 'ping' notification for new spots. Users can also adjust the number of spots displayed and select from several UI color schemes, including PSK Reporter and Ham Rainbow. The tool integrates with external callbook services like QRZ.com and HamQTH, allowing users to remember login credentials for seamless data reloading. A distinctive feature is the ability to input a personal grid square and manage lists of 'worked' and 'wanted' callsigns. Wanted callsigns, entered as space- or comma-separated lists, receive a gold highlight when a matching DX callsign appears in the spot feed, aiding in targeted DXing efforts. Beyond the interactive web interface, Spothole offers a universal JSON **API**, enabling developers to build custom applications leveraging its aggregated spotting data.

Txtopia provides a browser-based Morse code translator that converts plain text to International Morse Code and decodes Morse back into text, supporting various Unicode dot and dash representations. The tool automatically detects translation direction, normalizes common input variations like middle dots (·), bullets (•), em dashes, and underscores, and explicitly flags unsupported characters or ambiguous sequences with visible placeholders rather than silently dropping them. It accepts spaces, tabs, newlines, and pipes as letter separators, and slashes or blank lines for word boundaries, recording collapsed separators for user review. Users can adjust playback speed from 5 to 40 WPM and tone frequency from 300 to 1000 Hz for CW practice, with playback adhering to international Morse timing. The application operates entirely client-side, ensuring user input remains in the browser without server transmission. It includes a comprehensive reference for the supported Morse alphabet, numbers, and punctuation, aiding in learning and verification. The tool is suitable for checking game clues, verifying tattoo designs, and transcribing messages for ham radio CW practice.
