Open Source C Ham Radio Software

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 is designed for EME an VHF and higher frequencies. It provides a panoramic, polarization-matching receiver for the Q65 and JT65. modes. Programs WSJT and WSPR are interesting primarily for historical reasons. They are superseded by WSJT-X.

Fldigi is a modem program for most of the digital modes used by radio amateurs today: CW, PSK, MFSK, RTTY, Hell, DominoEX, Olivia, and Throb are all supported. It can help calibrate a sound card to a time signal and do frequency measurement tests. NOTICE: You must proceed to the Files section to locate the correct fldigi, flrig etal download for your particular operating system. Do not blithely use the big green Download button! Use the "Files" menu item or the "Browse All Files" link.

The Hamlib project's purpose is to develop flexible and portable shared libraries that offer a standardized API to control any radio oriented equipment through a computer interface.

Gpredict is a real-time satellite tracking and orbit prediction application. Gpredict can track an unlimited number of satellites and display the data in tables and various graphical view.

This repository contains hardware designs and software for HackRF, a low-cost, open source Software Defined Radio platform. HackRF One from Great Scott Gadgets is a Software Defined Radio peripheral capable of transmission or reception of radio signals from 1 MHz to 6 GHz. Designed to enable test and development of modern and next-generation radio technologies, HackRF One is an open-source hardware platform that can be used as a USB peripheral or programmed for stand-alone operation. HackRF One has an injection-molded plastic enclosure and ships with a micro USB cable. An antenna is not included. ANT500 is recommended as a starter antenna for HackRF One. HackRF One is test equipment for RF systems. It has not been tested for compliance with regulations governing the transmission of radio signals. You are responsible for using your HackRF One legally.

A Smith charting program. You can enter either discrete components or transmission lines, see the results on screen and/or generate Postscript output. Component values can be changed numerically or using scrollbars.

NOTE: Code commits are FROZEN on SourceForge: New code is now at <http://github.com/Xastir/Xastir>. Real-time tracking & messaging of stations via radio/internet APRS data streams, w/125 map formats supported. Linux/FreeBSD/Solaris/MacOSX/Windows in any of 7 languages. Can also be used for mobile mapping w/GPS. MAILING LISTS ARE AT: PROJECT->WEB SITE.

Umbrella project for cw, cwcp, xcwcp, cwgen programs, and for libcw library.

CWStudio is a portable almost library-independent and computationally efficient generator of CW signals for telegraphy training purposes. It can create a sound with maximum similarity to the real air, simulating many difficulties.

The Ground Station Software Suite projects aims at providing free, useful software tools for ham radio operators. Currently, this projects hosts the Grig communication radio control. The source repository has been moved over to github.

Repeater controller and EchoLink software for Linux including a GUI, Qtel - the Qt EchoLink client. The SvxLink project has now moved to GitHub. The new home page for the project is http://svxlink.org/ .

Convert text to International Morse Code. Input is ASCII text. Output can be: - . -..- - on the console, raw 8bit PCM suitable for piping to /dev/audio, .wav files or even (mp3|ogg). Good for headlines on your MP3 player or code practice.

A handy stand-alone GTK+ client for accessing your favorite DX Cluster or Reverse Beacon Net server via telnet over TCP/IP.

The SARK100 SWR Analyzer (https://sites.google.com/view/sark100) is a measurement instrument which determines antenna system performance across the HF/6M amateur bands through use of automatically collected SWR and complex impedance readings.

Acarsdec is an open source, multi-channels realtime ACARS decoder for Linux. It features : - up to four channels decoded simultaneously - error detection AND correction - input from sound file , alsa sound card or software defined radio (SRD) via a rtl dongle (http://sdr.osmocom.org/trac/wiki/rtl-sdr) or airspy (http://www.airspy.com) - could send decoded acars to a server via UDP in planeploter format or its own dedicated format. The 4 channels decoding is particularly useful with the rtl dongle. It allows to directly listen simultaneously to 4 different frequencies , with a very low cost hardware. Since version 3.0, acarsdec comes with acarsserv : a database backend program to store received acars messages.

Voice over IP (VoIP) software specifically for ham radio operators. The primary purpose is to use the Internet to link Ham repeaters with a secondary purpose of providing remote access for users. Compatibility with EchoLink and IRLP is a goal.

Digital Speech Decoder and xMBE codec library - To decode various xMBE based, QPSK, C4FM modes such as P25 Phase 2 (TDMA), MotoTRBO, ProVoice, NexEDGE and others..

WinAFSK is a Microsoft Windows application (XP/7/8/8.1/10 [Vista has some issues]) which allows you to decode AFSK1200, AFSK2400, HAPN4800 and FSK9600 packet data in real time from any audio device on your machine such as a radio or sdr device. If you dont have radio equipment, you can use the VirtualAudioCable application or something similar to decode signals off of http://websdr.org
