First released in 1988, _SWLog_ is a comprehensive suite of applications providing logging and remote control for both amateur radio and shortwave, utility, and broadcast listening. It integrates program schedules from sources like _HFCC_, _ILGRadio_, and _EiBi_ for broadcast reception, while also linking with amateur radio logbooks such as _ClubLog_, _eQSL_, _QRZ_, and _LoTW_. The software supports radio control for various transceivers, including _Flex_, Icom, Yaesu, and Kenwood, alongside interfaces like _FLRig_, _OmniRig_, and _HamLib_. Mobile applications for Android and iOS facilitate on-the-go logging and remote control, seamlessly transferring logs without manual ADIF export. _SWLog_ leverages an enterprise-grade relational database (SQL Server) for robust data management and analytics, enabling features like mapping QSOs by band or state. It offers specific integrations for _POTA_ monitoring, displaying active spots with real-time propagation and automatic radio tuning. The application's scalability allows multiple users to log to a centralized database, suitable for Field Day or DXpeditions. The user interface features modern aesthetics with light, dark, and gray themes, the latter optimized for outdoor visibility during activities like _POTA_ or _SOTA_. The Plus Edition, available for an annual fee, expands capabilities with advanced QSL integration, additional map providers, and enhanced propagation calculations using _VOACAP_.

This transmitter covers the 160, 80, 40 and 20 metre bands and provides both SSB and properly generated CW. The CW side of this transmitter is not compromised and produces excellent CW. On SSB the audio has been tailored to provide a rising response to 3 KHz, with a sharp drop above that frequency. There is RF speech clipping to both provide more "punch" and to limit the peak output.

ADIF-to-QSL-label is a GitHub utility designed to generate print-ready PDF QSL labels from ADIF log files. Optimized for the Avery Zweckform 3664 format (A4, 3×8 grid), the tool accommodates up to four QSOs per label. While an HTML version is suggested, the Python script provides extensive customization via the reportlab library. Users can precisely calibrate the layout through single-point configuration, adjusting page margins, global X/Y offsets, and specific column or row nudges. Key features include dynamic column sizing, support for any ADIF field (such as RST or Mode), and debugging tools that print outlines and guides for alignment testing. Configuration is managed via the script, YAML files, or CLI arguments, requiring "Actual size" (100%) printer settings for accuracy.
