    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 They are superseded by WSJT-X.

    vJoy
    This project was originally designed to provide an open-source replacement for PPJoy. The product, at this point, consists of virtual joystick devices that is seen by the system as a standard joystick but its position-data is written to it by a feeder application. An existing feeder application that takes advantage of this product is SmartPropoPlus. If you are an application writer you can very easily write an application that controls a joystick (e.g. mouse-to-joystick, keyboard-to-joystick). If you are a beginner in device drivers you can take this code and enhance it to support more (or less) axes, buttons or POVs.
