Open Source 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 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 They are superseded by WSJT-X.

Open source libraries and utilities to support using digital signatures for Amateur radio QSL information.

A cross platform Python frequency scanning GUI for USB TV dongles, using the OsmoSDR rtl-sdr library. In other words a cheap, simple Spectrum Analyser. More information can be found at: http://eartoearoak.com/software/rtlsdr-scanner An installer and standalone versions for Windows are located here: https://github.com/EarToEarOak/RTLSDR-Scanner/releases Sources are available on GitHub: https://github.com/EarToEarOak/RTLSDR-Scanner ** The up to date installer is no longer maintained on this site and can now be found at https://github.com/EarToEarOak/RTLSDR-Scanner/releases **

A software gps simulator, providing TCP/IP, UDP, http and serial port connectivity in NMEA 0183, XML or user defined output format. Usable for testing all kinds of GPS applications. Can playback pre-recorded GPS files with NMEA output.

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.

Morse Code (CW) decoder for Unix-like systems (and Windows).

QAntenna is able to show antennas in a 3D plot, and calculate it's radiattion pattern. It is capable of working with many antennas at the same time.

A morse code trainer for Gnome. Teaches morse code using the Koch method. Requires GTK+ and Pulseaudio.

A program for use by radio hobbyists to decode the data sent to mobile display terminals used by taxi companies.

FreqLength is a simple wavelength calculator that takes a given frequency as input and spits out various wavelength values for that frequency (full wave, half wave, etc.) If you'd like to donate there's several ways to do so: PayPal: https://paypal.me/gerowen Bitcoin (BTC): bc1q86c5j7wvf6cw78tf8x3szxy5gnxg4gj8mw4sy2 Monero (XMR): 42ho3m9tJsobZwQDsFTk92ENdWAYk2zL8Qp42m7pKmfWE7jzei7Fwrs87MMXUTCVifjZZiStt3E7c5tmYa9qNxAf3MbY7rD LiberaPay: https://liberapay.com/gerowen

Small Portable Rotator: a simple, lightweight, self-consistent antenna rotator for amateur radio satellite tracking, plus an optional portable controller. *** CHANGELOG *** [version 1.0]: - Added tighter control over rotation limits - Fixed some minor bugs - With the 'V' command the version is displayed and no longer the "built filename"

JMorseTrainer helps you to learn or improve Morse code.

JOSAST ( Java Open Source Amateur Satellite Toolkit) is a set of java source code used for amateur satellite, hamradio and also astronomia activities ... Reusable package and complete software should be available.

JeAPRS is a Java Language based Packet Radio library intended for the users of APRS and similar AX.25, UI Frame based communications in the Amatuer Radio Community. The library includes an object oriented infrastructure for APRS data packets, but is ext

This project is to create the hardware and software for a family of software defined radios for microwaves and maybe other bands too. The DSP in the software is based on DttSP from the SDR-1000.

finds exact gain, directivity and input impedance of Yagi or log-periodic antennas (planar symmetric array of cylindrical dipoles, many driven elements) for a range of specified frequencies, integrates 2D for segments on the same element, moment method

A portable library to control the ICOM PCR-1000 computer controlled general purpose radio receiver and gui front ends for X, Aqua, and windows32

Collection of HAM radio APRS tools: - METAR to APRS WX data injector

Tracks runner's in/out time at each aid station. Saves data in CSV file. Can be configured for other races. AidStations.txt in repository contains the 15 or so Aid Stations used for the Bear100. The Bear100 is an annual 100 mile, 2 day race on foot through the Rocky Mountains in North America. Will communicate via serial over a 1200 baud AX.25 link to a ARES/Data backend (which we call NetControl). Can initialize some hardware TNCs with parameters optimal for ARES/Data topology. See ARES paper for topology/backend: http://www.tapr.org/pub_cnc07.html All Aid Stations are expected to use same frequency concurrently, and optionally send queries to Net Control. Note backend will support more frequencies if more radios were hooked up. Expected that subset of stations will use software. Remainder will communicate runner data via voice to NetControl.

Test your knowledge of ARRL and RAC Sections and US States and Canadian provinces. Helps improve your logging rate for all Ham Radio contests that require logging sections, or states, and provinces, including Field Day, Sweepstakes, ARRL DX, etc

Next generation APRS iGate for HAM radio use.

The DXSpider DX Cluster is a linux based, (mainly) perl program designed to provide the same general functionality (and more) as the DOS version originally written by Dick Newell AK1A.

A CW beacon implemented in C language on a AVR AtTiny13A microcontroller (1KB flash!). Include a CW parametric modulator/keyer, an emulated I2C periferal and a device driver in order to handle the Si570 oscillator by Silabs. You can personalize the transmitted message and the morse speed (in WPM). In the example the beacon is IQ6MC/B JN63RH @ 144.450MHz. Enjoy this example and if you will appreciate it, please sens me a feedback! IW6DFW, Maurizio
