HFsignaler

HFsignaler is a software platform designed for monitoring, analyzing, and logging high-frequency (HF) radio signals. It targets amateur radio operators, researchers, and professionals who work with the HF bands (roughly 3 to 30 MHz). The system typically interfaces with software-defined radios and other HF hardware to provide real-time spectrum visualization, demodulation, and data logging.

Key features commonly associated with HFsignaler include configurable spectrum and waterfall displays, multiple demodulation modes (such as AM, SSB, CW, and certain digital modes through plugins), automatic signal identification, and event logging. Additional functionality may include QSL management integration, scripting or plugin support to extend capabilities, and cross-platform operation across Windows, Linux, and macOS. Support for popular SDR devices (for example RTL-SDR, HackRF, and Airspy) is often highlighted, along with networked radio integration for collaborative work.

In typical use, HFsignaler runs as a client application that gathers data from connected radios, processes it locally, and may optionally stream data to a central server for shared analysis. It is used for activities such as monitoring long-distance stations, tracking propagation conditions, and studying HF band activity. The software emphasizes responsible operation and compliance with applicable regulations governing radio transmission and monitoring in different jurisdictions.

Availability and licensing of HFsignaler vary by variant, with some editions offered under open-source licenses and others under commercial terms. Users should review the specific licensing terms and hardware compatibility for the version they intend to use. See also shortwave radio, amateur radio, and software-defined radio.
