Operating the UoSAT-2 (OSCAR-11) satellite, launched in 1984, presents unique challenges due to its age and current eclipse schedule. This resource provides a historical archive of news, telemetry data, and specialized software for decoding its 145.826 MHz FM beacon. It includes tools like _CTERM_ for terminal emulation and capture, and U2TM for processing ASCII telemetry, enabling hams to analyze the satellite's health and performance. The site also offers audio samples of the beacon and S-band signals, along with details on hardware and software decoders. Reception reports are actively solicited for the satellite's intermittent transmissions, which occur for less than an orbit every 21 days during its eclipse period. The site details how to process raw telemetry data, including instructions for skipping initial frames to improve decoding accuracy with U2TM. It also provides software like SATILL for predicting solar eclipses and tools for determining the satellite's spin period from magnetometer or solar array telemetry, offering insights into its operational status despite its advanced age.

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.
