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. -

HAMLIB SDK (Evolved JTSDK)
Hamlib Software Developer's Kit Supporting Qt & JT-based HAM Software
The aim is to support learning withinof Hamlib-centric software . See https://hamlib-sdk.sourceforge.io . This kit is designed to support research and learning into Hamlib (https://sourceforge.net/projects/hamlib/) and WSJT-X (https://wsjt.sourceforge.io/wsjtx.html). Follow discussion at JTSDK @ GROUPS.IO . The file(s) needed to deploy the kit are : - https://sourceforge.net/projects/hamlib-sdk/files/Windows/JTSDK-4.1-Stream/JTSDK64-4.1.1.exe - https://sourceforge.net/projects/hamlib-sdk/files/Windows/JTSDK-4.1-Stream/JTSDK64-4.1.1-U1.exe Hamlib is dynamic due to the differences in hardware capabilities. See: https://sourceforge.net/projects/hamlib/ Current efforts focus on learning and compiling "JT" software. Packages are provided that enable kits to be easily maintained and updated.

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. -

MFJ-993b Web Remote
Arduino Mega 2560 + Ethernet Shield to control 8 Relays for MFJ-993b
Arduino Mega 2560 Code with a standard Ethernet Shield that drives Relays to control a MFJ-993b Autotuner remotely. Supports Up and Down for manual L and C Tuning, Autotune On/Off, Antenna Selection 1/2 and 100ms Short /1000ms Long for Tune. Op Note 1: You may need additional power for the 5V relay board; sometimes you can power the 5V relay board from the Mega 2560 - but reset/start the device first and then connect power to the relay board. Op Note 2: You will need determine pinouts to the MFJ-993b DB9 yourself. This is easy to determine; refer to the manual at https://mfjenterprises.com/products/mfj-993b#product-manuals *Note for ESP32* See https://github.com/dl9sec/MFJ-993WWRC for working with ESP32 modules. It works very well with the MFJ-993B and is a great project! Opto-Isolators are recommended rather than FETs ! Enhancements to this may appear that include additional functionality that this project incorporates. -

MATTA
Morse Code Utilitiies to convert text messages to & from sound files.
This is a commandline utility that converts a WAV sound file containing morse code to English text. Pre-built binaries run on OSX, MsWindows, & GNU/linux. It is written in Ada, so can be rebuilt on any platform with an Ada compiler. The input wav file must be monaural, with a 16-bit signed integer encoding, and a sample rate of 8000 Hz. Either sox or audacity can easily transform to this format. The wav file is expected to be international morse code, preferrably clean and properly spaced. Tonal frequency or wpm-speed does not seem to matter. Now includes an inverse commandline app, txt2wav that creates a morse code WAV file from English text. The proper command to extract the archive and maintain the directory structure is "7z x filename". -

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. -

mshv-auto-dx-chaser
Autonomous, intelligent DX hunting engine for MSHV ham radio software
What if your radio could hunt DX the way you do? The Auto DX Chaser watches the bands with the patience of a seasoned operator. It knows P5 is worth dropping everything for. It knows to keep calling that rare African station a little longer. And when someone finally comes back to you, it locks on and never lets go—just like you wouldn't walk away from an in-progress QSO. This isn't automation. It's intuition, codified. The system pulls intelligence from RBN, PSKReporter, and DX Clusters simultaneously—but only calls stations YOUR radio can actually hear. It scores every decode using Club Log's "Most Wanted" rankings, signal quality, and what you still need. New all-time DXCC? Top priority. Already worked on this band? Skip it. Search and pounce only. Never calls CQ. Waits for the DX to appear, then pounces—exactly like you would during a DXpedition pileup. Your shack. Your radio. Your log. Just smarter hunting. By HamB0T. 73! -
