First released around 1995 and significantly redesigned as QWTelnet 2, this software provides a dedicated interface for monitoring DX-Cluster traffic via Telnet. It integrates a **SOTAwatch parser** with configurable audio alerts, allowing operators to receive notifications for specific search patterns in DX-Cluster remarks without constant screen attention. The application also supports parsing for **GMAwatch (German Mountain Award)**, providing alerts for German Mountain Award activations. QWTelnet 2.4.0, released on 07-APR-2012, runs on Windows (tested on W7) and is distributed as a ZIP file containing the `qwtelnet.exe` executable. It does not require a formal installation process; users simply extract and run the program. The software can display DX information for single bands, integrate with the Reverse Beacon Network, and link to external web resources for DXCC and SOTA information. It also supports local reference files for IOTA, WFF, and RDA awards, which users must source and place in the `qwtelnet/files` directory. For IOTA data, users can convert `IOTA.CSV` from UCX-Log or `DX4WIN_IOTA.TXT` into `iota.csv`. WFF and RDA reference files are directly sourced from their respective websites. -
