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 They are superseded by WSJT-X. -

SDR++
Cross-Platform SDR Software
SDR++ is a free, open-source software-defined radio application designed for receiving and analyzing radio signals through compatible SDR hardware. It provides a lightweight interface for tuning frequencies, viewing spectrum activity, and demodulating transmissions. The application supports multiple virtual frequency oscillators, allowing users to monitor several signals within an available bandwidth. Its hardware compatibility includes dedicated receiver modules and devices supported through SoapySDR. SDR++ uses SIMD-accelerated digital signal processing for efficient signal handling. Its waterfall display provides detailed visualization of radio activity over time. Available for Windows, macOS, Linux, and BSD, it features a modular architecture that allows developers to extend functionality through plugins. -

echoes
Echoes is a radio spectral analysis software for SDR devices
Echoes it's a radio spectral analysis software for SDR devices, designed for meteor scattering purposes. The older releases supported only RTL-SDR devices. They are very cheap SDR based on DVB-T TV tuner dongles based on Realtek's RTL2832U chipset. Starting from 0.50 Echoes embeds SoapySDR allowing the support of many other SDRs. Echoes doesn't demodulate neither decode any human-made signal. Its main goal is to analyze and record the total power of natural signals and generate screenshots and tabular data (CSV,) output in presence of particular peaks in a selected narrow range of frequencies. Since there is no demodulation, there is no provision for audio listening, except for a notify sound when an event has been recorded. Finally, Echoes can also operate getting an audio input, thus producing audio spectra. This way, Echoes can also be used with traditional receivers. -

VBandHack
Enables the full use of the BH8DZE CW trainer on the VBand website.
This tool allows you to fully use the inexpensive BH8DZE CW trainer USB stick on the VBand website. Like me, did you buy a cheap BH8DZE USB stick on Aliexpress to connect your CW keyer and practice on the VBand website? Only to find out it doesn’t fully work — even with the 'Use mouse buttons' option enabled? Specifically, the 'dah' (right) key doesn’t function in iambic mode. That’s why I built this tool — to fix it for you! First, let me explain why the BH8DZE doesn’t work properly. This stick emulates the left and right mouse buttons when you press 'dit' and 'dah' on your CW keyer. So when you press 'dah', instead of producing the sound you need (with the option mentioned above enabled), the browser just pops up a context menu. My program works in a very straightforward way. It intercepts mouse clicks when it detects that the VBand site is open, and replaces them with keyboard presses: 'LEFT CTRL' and 'RIGHT CTRL'. And everything OK! !! Disable 'Use mouse buttons' !! -

FT-710 Settings Manager
Demo of Claude-based shell allowing FT-710's settings to be edited
FT-710 Settings Backup and Manipulation Tool =================================== This is a demonstration Qt6 C++ mingw64 program that was initially generated in a Claude.AI shell to manipulate, read, edit, backup-save and backup-reload a FT-710's settings. [ It is noted that this can be done to a SD-Card ... This works with PCs and Macs ] It also demonstrates that LLM's are not the sole answer - as to be of utility one must "tweak" what comes out of LLMs. Note: NO EXECUTABLES SUPPLIED. You must build this with an Open Source Qt SDK - available at https://www.qt.io/development/download-qt-installer-oss . Supporting Open Source and access to Open Source.
