    WSJT

    WSJT

    Weak signal ham radio communication

    The WSJT project implements software for amateur radio communication using state-of-the-art digital techniques. Typical applications involve "DXing" at LF, MF, HF, and VHF+ frequencies, including meteor scatter and EME ("moonbounce"). Major emphasis is placed on weak-signal techniques. Summary Program Descriptions: WSJT-X supports the communication protocols FST4, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, FST4W, and Echo, each optimized for different sorts of radio-wave propagation. MAP65 and QMAP are designed for EME at VHF and higher frequencies. MAP65 provides a panoramic, polarization-matching receiver for the Q65 and JT65. modes. QMAP works together with WSJT-X to provide a panoramic receiver for Q65 modes covering a 90 kHz sub-band. Programs WSJT and WSPR are interesting primarily for historical reasons. They are superseded by WSJT-X.

    Nexus Ham Radio

    Nexus Ham Radio

    All-mode ham radio operations center: 9 modes TX, APRS, awards

    Nexus puts the whole ham station in one modern app: FT8/FT4 with WSJT-X-grade sequencing plus Q65, FST4, FST4W, MSK144, JT65 and WSPR all transmitting, RTTY, SSTV, APRS, SSB/FM phone, and CW with a neural-net decoder. The rig's own RF panadapter streams into the cockpit on native-CI-V Icom and FlexRadio. The waterfall pauses and rewinds. Route each band and mode to the radio that does it best, across up to three rigs. Awards (DXCC, WAS, WAZ, VUCC, IOTA) compute offline, and an eQSL or QRZ match never inflates an LoTW-grade award. Propagation uses a native ITU-R P.533 port and scores openings on receivers near you, not the global firehose. APRS draws real station symbols, decodes weather reports, connects to APRS-IS, and runs a receive-only iGate. Speaks WSJT-X's UDP protocol byte-for-byte, so GridTracker and JTAlert keep working. Its FT8/FT4 decode floor measures -21.3 dB against stock WSJT-X's -20.7 on identical audio. Windows, Linux, Raspberry Pi. GPL-3.0, by KD9TAW.

    Cosmos

    Cosmos is an operating system "construction kit"

    Cosmos is an operating system "construction kit" made for Visual Studio 2022. Build your own OS using managed languages such as C#, VB.NET, and more! Cosmos (C# Open Source Managed Operating System) is an operating system development kit that uses Visual Studio as its development environment. Despite C# in the name any .NET-based language can be used including VB.NET, Fortran, Delphi Prism, IronPython, F# and more. Cosmos itself and the kernel routines are primarily written in C#, and thus the Cosmos name. Cosmos is not an operating system in the traditional sense, but instead, it is an "Operating System Development Kit". Cosmos lets you create operating systems just as Visual Studio and C# normally let you create applications. Most users can write and boot their own operating system in just a few minutes, all using Visual Studio.

    librsb

    librsb

    A shared memory parallel sparse matrix library including Sparse BLAS.

    librsb is a library for sparse matrix computations featuring the Recursive Sparse Blocks (RSB) matrix format. This format allows cache efficient and multi-threaded (that is, shared memory parallel) operations on large sparse matrices. The most common operations necessary to iterative solvers are available, e.g.: matrix-vector multiplication, triangular solution, rows/columns scaling, diagonal extraction / setting, blocks extraction, norm computation, formats conversion. The RSB format is especially well suited for symmetric and transposed multiplication variants. On these variants, librsb has been found to be faster than Intel MKL's implementation for CSR. Most numerical kernels code is auto generated, and the supported numerical types can be chosen by the user at build time. librsb implements the Sparse BLAS standard, as specified in the BLAS Forum documents.
