CHIRP is a free, open-source tool for programming your amateur radio. It supports a large number of manufacturers and models, as well as provides a way to interface with multiple data sources and formats.

CWStudio is a lightweight, 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.

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.)

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.

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.

The WSJT project /sourceforge currently includes five programs designed for amateur radio communication using state of the art digital techniques. Typical applications include meteor scatter, EME ("moonbounce"), and QRP communication at HF.
Summary Program Descriptions:
WSJT: Modes JTMS, FSK441, ISCAT, JT6M, JT65, JT4, Echo, CW. 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.
