• CubicSDR a Cross-Platform Software-Defined Radio Application.
• insprectrum is a tool for analysing captured signals, primarily from software-defined radio receivers.
• ShinySDR is the software component of a software-defined radio receiver like the HackRF or RTL-SDR.
• SDRangel SDR and signal analyzer frontend to various hardware.
• PyMultimonAPRS can take an RTLSDR or audio input and Igate APRS traffic.
• OpenWebRX Open source, multi-user SDR receiver software with a web interface, forked and improved from HA7ILM's excellent initial project.

  • WSJT: Modes optimized for meteor scanner, ionospheric scatter, and EME at VHF/UHF/Microwaves.
  • WSJT-X: Modes JT65, JT9. Primarily for use at HF.
  • MAP65: For EME an VHF and higher frequencies. Implements a panoramic, polarization-matching receiver for JT65.
  • WSPR: Probe potential propagation paths using low-power transmissions.
  • WSPR-X: Experimental version of WSPR, including the slow mode WSPR-15.

• fldigi is a modem program for most of the digital modes used by radio amateurs today.

Libraries

• Hamlib libraries for amateur radio equipment control applications.
• pyhamtools is a set of functions and classes for Amateur Radio purposes.
• Codec2 is a FOSS ultra-low bitrate voice codec that's competitive from 3200 bits/s down to 450 bits/s. Also includes FreeDV, an HF digital voice mode. PyCodec2 is an easy Python wrapper.
• CSDR csdr is a command line tool to carry out DSP tasks for Software Defined Radio.

Radio programming

• CHIRP a free, open-source tool for programming your amateur radio.
• editcp a codeplug editor for the Tytera MD380 and MD390 as well as the Alinco DJ-MD40 radios.

Satellite operation

• Gpredict a real-time satellite tracking and orbit prediction application.
• gr-satellites GNU Radio decoders for several Amateur satellites.

Training

• AFU Group Trainer a tool that eases the collaborative learning for the (German) HAM exam by allowing each student to answer the questions during a learning session instead of just one person answering. (Currently only in german)

Hardware

• MMDVM Multi-Mode Digital Voice Modem

  • MMDVM_HS_HAT for the Raspberry Pi (Zero)

• HPSDR a hardware and software project intended as a "next generation" Software Defined Radio (SDR) for use by Radio Amateurs.
