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 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 They are superseded by WSJT-X.

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.

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

Gqrx is a software defined radio receiver powered by GNU Radio and the Qt GUI toolkit. It can process I/Q data from many types of input devices, including Funcube Dongle Pro/Pro+, rtl-sdr, HackRF, and Universal Software Radio Peripheral (USRP) devices.

Qtmm is a simple AFSK1200 decoder that uses the computer's sound card for input. It can be used to decode packet radio, APRS and telemetry from amateur radio satellites.

Hamradio HF digital teletype modem for PocketPC.

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.

Minos is a VHF contest logging program, together with a collection of programs to assist with station and site operation.

This project aims to implement open source versions of current amateur radio digital voice protocols, including client software, repeaters, and gateways.

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.

PowerSDR-sr40 is a branch of PowerSDR (www.flex-radio.com) and adds features for use with a SoftRock40 Radio. It is a near Zero-IF Quadrature Software Defined Radio (SDR). Features includes; TX capabilities, IQ sample correction, Dual Soundcard support.

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' !!

aprsd is a server daemon that provides Internet gateway and client access to amateur radio APRS packet data.
