Versions:
Thetis 2.10.0.0, released by the OpenHPSDR/TAPR consortium, is the current and only version of the official Windows client for the High-Performance Software Defined Radio (HPSDR) project. Positioned in the amateur-radio and software-defined-radio category, the application turns a general-purpose PC into a high-fidelity transceiver front-end when paired with Mercury, Penelope, Pennylane, Metis, Hermes, Angelia, Orion, Orion-II or Red Pitaya RF boards. Operators rely on Thetis to conduct everyday HF through UHF contacts, contest logging, weak-signal digital work, satellite uplink/downlink experiments, and real-time spectrum monitoring; its 1.3 megapixel panadapter, selectable pre-distortion, diversity noise-reduction, multiple receive slices, and 384 kHz maximum bandwidth give experimenters laboratory-grade tools without dedicated bench instruments. Because all demodulation, filtering and modulation logic runs on the host CPU, upgrades arrive as simple software downloads rather than costly hardware swaps, letting amateurs evolve their stations as coding advances. The program exports a fully documented C# API, so third-party developers routinely embed Thetis panadapter data into logging suites, Morse-code trainers, or automated propagation reporters. Rig-control via Omni-Rig and Hamlib, TX audio shaping through VAC or ASIO, and integrated support for CW, SSB, AM, FM, and digital modes such as FreeDV and FT8 make the package a single-window solution for both casual operators and graduate research groups exploring open-source radio architectures. For administrators who need repeatable deployment across club shacks, classrooms or contest rooms, the software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
