WS - Digital Mode Suite
formerly known as WSJT-X Improved
WS is an innovative suite of programs for weak-signal digital communication in amateur radio by Uwe Risse DG2YCB et al., formerly known as WSJT-X Improved. WS grew out of WSJT-X by Joe Taylor K1JT, Steve Franke K9AN, Bill Somerville G4WJS, Uwe Risse DG2YCB and others (https://sourceforge.net/projects/wsjt/). The WS Suite consists of three programs: WS (the main program), WS-MAP (wideband Q65 monitor) and EME65 (wideband JT65/Q65 for EME). The WS main program supports FT8, FT4, FT2,... -

70cm-ham-radio-fox-hunt-receiver
70cm Amateur Radio Fox Hunt CW receiver - Heltec V3 ESP32 LoRa Board
This project is intended to be coupled with my other LoRa board based project, 70cm Ham Radio Fox Hunt Beacon, which can be found at the link below: https://lora-ham-fox-hunt-beacon-70cm.sourceforge.io The receiver, also ESP32 LoRa-based, is designed for simplicity and accessibility, requiring minimal user setup. It features an OLED display providing real-time frequency readout and received signal strength indication (RSSI), presented numerically in dBm, as an S-meter value, and via a graphical bar. The system supports direction-finding applications, with provision for a compact 4-element Yagi antenna to enhance signal localisation. CODE FOR THIS PROJECT HAS NOW BEEN RELEASED. Download the Arduino Sketch from the Files section. 27/06/26 - NEW Version Released with configuration Web GUI https://youtube.com/shorts/7QMwPYFFLZA If you are new to ARDUINO, then please download the 'Quick Start Guide' from the File section. -

70cm-ham-radio-fox-hunt-beacon
70cm Amateur Radio Fox Hunt CW Beacon using Heltec V3 ESP32 LoRa Board
...The beacon transmits a user configurable, identification string, in Morse code at 12 WPM, followed by a 10-second carrier and 20-second pause cycle. It operates at ~10 mW, offering several hours of runtime on an 800 mAh battery. The firmware allows full parameterisation in code, including operating frequency, CW speed, transmit message, carrier duration, pause interval, and RF output power adjustable from -9 dBm to +21 dBm (0.12 mW–125 mW). A programmable button enables TX disable and deep sleep mode. The receiver project is published on its own project page: https://lora-ham-fox-hunt-receive-70cm.sourceforge.io 27/06/2026 - NEW VERSION 2 Released - Web GUI Download the Arduino Sketch from the Files section. ... -

MATTA
Morse Code Utilitiies to convert text messages to & from sound files.
...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". -

Hardcoder
Hardcoder is a solution which allows Android APP and Android System
Hardcoder is a solution that allows Android APP and Android System to communicate with each other directly, solving the problem that Android APP could only use system standard API rather than the hardware resources of the system. Through Hardcoder, Android APP can make good use of mobile phone hardware resources such as CPU frequency, Large Core, and GPU to improve APP performance. Hardcoder allows Android system to get more information from the APP in order to better provide system resources to Android APP. At the same time, due to the lack of implementation by the standard interface, the APP and the system can also realize the model adaptation and function expansion through the framework. ... -

HF-Sounder Version 1.4 (Beta)
Finds best HF band for site-to-site communications using Fldigi
...In the second half of the ten minute cycle, the remote site becomes the listener and the NCS transmits a text message on the band where the remote site's signal was strongest. Both stations then switch to that frequency and start operating. If more than two stations in the net, the other stations can use the tool in Listener mode, and switch to the band announced by the NCS at the end of the sequence. -
