Radio Explorer - Graphic viewer for shortwave broadcasting and programming schedules. Supports viewing schedules in an expanding table and on a 24-hour Gantt chart using the local time and the UTC time display modes. Runs on multiple platforms.

Grig Radio Control - Grig is a freeware simple Ham Radio control (CAT) program based on the Ham Radio Control Libraries (Hamlib). It is intended to be highly generic presenting the user to the same graphical user interface regardless of which radio is being controlled. Grig supports the most commonly used CAT commands that are implemented by Hamlib, and integrates well with other ham radio programs like Xlog and gMFSK. Grig has been developed on Linux, but has been ported on Mac and Windows OS.

X-APRS - APRS™ for Linux is a multifaceted system for use with packet radio by Hams, it allows the monitoring of real time geographical information such as the position of vehicles, the status of weather, radio direction finding and much much more. It envolves mapping, GPS tracking, packet radio, etc

XASTIR - Xastir is program for receiving and plotting APRS™ position packets. Development is a collaborative effort of programmers and amateur radio enthusiasts from around the world. Xastir supports many map formats and is highly customizable. Xastir runs on Windows/MacOSX/Linux/FreeBSD/Solaris/Lindows. It supports 125 map formats, several types of TNC's and weather stations, Festival speech synthesizer, AX.25 networking (Soundmodem/Baycom/SCC!) and seven languages!.

Acarsd - acarsd is an ACARS decoder for a LINUX or Windows PC which attempts to decode ACARS transmissions in real-time using up to three Soundcards. acarsd is also a realtime ACARS Server, for the worldwide spotter and ACARS community.

FFT Explorer - A free (GPL) Linux (Xwindows GUI-based) utility that performs spectral analysis on real-time data from a sound card or other source, and can analyze the spectra of various sound file types. It can also accept data from many kinds of applications in plain-text form by way of the "named pipe" feature of Linux

Visual Moon Tracking - Java moon tracking software runs on LINUX, Win 98, Win NT, UNIX, OSF, MacOSX

SuperNEC antenna simulation - Hybrid Method of Moment (MoM) and Geometric Theory of Diffraction (GTD) program. Matlab based GUI interface. Genetic optimizer included. Windows/Linux versions.

CLLOG - Free german Open Source HAM Logging Program unter the terms of the GNU General Public License. CLLOG runs under MS-DOS (Windows DOS-Window under 3.x,9x,NT,ME,2000) and LINUX. All Functions for Logbook.

Linrad - Multiplatoform freeware DSP software. Linrad has its origin in software that was developed for 144 MHz EME CW but it is quite general and should be seen more like a kit for designing a receiver that a receiver for some particular usage. It can be used as a CW receiver with a small time delay and a fast waterfall graph. A dsp for conventional receiver to imporve signals readability, a spectrum analyzer.

jLog - jLog is a modern Freeware Ham Log program that can run on all major platforms, e.g. Mac OS X, Mac OS, Linux/Unix, Windows, etc. It offers a nice, clean interface and allows efficient entry of QSOs. Import or Export of data using the standardized ADIF 2 format is possible to easily exchange data with any other decent Log program. Built-in CW Keyer, CAT control for many popular, rigs, DX Cluster tracking, call lookups

FBB Packet-radio BBS - FBB is a freeware bulletin board software for amateur packet-radio run on DOS Windows and Linux

QSSTV for Linux - SSTV program for the Linux platform with several functions written by ON1MH Johan

Satscape - Satscape is a freeware program for the PC Macintosh and Linux. It produces real-time displays of where any Satellite is, and predicts passes for your locale. There are about 8000+ satellites in orbit, a lot of these are just junk and debris such as discarded rocket bodies, but quite a few are working Satellites.

Fldigi - Freeware Digital modem program for Linux, Free-BSD, OS X, Windows XP, W2K, and Vista. Support several modes and is fully multi platform application by W1HKJ

LinPsk - Psk31 program for Linux, supports up to four simultaneous receive windows.

AFU Knoppix - The AFU Knoppix CD contains software for the operating modes of PSK31, RTTY, SSTV, FAX, APRS and packet radio. Additional applications for Sat tracking, logging, locator referencing and antenna computation are also included. The CD is targeted for radio enthusiasts, the Linux operating system and the applications on this CD are structured so that they can run from the CD without effecting the installed existing system software. *
