Open Source Ham Radio Software

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.

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.

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

A Smith charting program. You can enter either discrete components or transmission lines, see the results on screen and/or generate Postscript output. Component values can be changed numerically or using scrollbars.

Repeater controller and EchoLink software for Linux including a GUI, Qtel - the Qt EchoLink client. The SvxLink project has now moved to GitHub. The new home page for the project is http://svxlink.org/ .

A handy stand-alone GTK+ client for accessing your favorite DX Cluster or Reverse Beacon Net server via telnet over TCP/IP.

NOTE: Code commits are FROZEN on SourceForge: New code is now at <http://github.com/Xastir/Xastir>. Real-time tracking & messaging of stations via radio/internet APRS data streams, w/125 map formats supported. Linux/FreeBSD/Solaris/MacOSX/Windows in any of 7 languages. Can also be used for mobile mapping w/GPS. MAILING LISTS ARE AT: PROJECT->WEB SITE.

When operating any hamradio software that doesn’t control the PTT (push to talk) button of the radio you can use ColorVox to operate the PTT thru the COM port when some specific pixels at the screen change the color to a specific color you select. This software evolves the concept of voice operated relay (VOX) well known in hamradio activity to color operated relay (ColorVox) that is the innovation it introduces.

KPSK - An easy to use PSK31 terminal program for amateur (ham) radio.

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.

Codegroup is a Java application that will allow one to convert binary (or text) computer files in to 5 letter codegroups for transmission over email, landline telephones, radioteletype or Morse Code. Codegroup has internal error correction & limited cryptography capabilities.

KLog is a Ham Radio Logging program for KDE. It manages QSL, awards, DXCC, WAS, TPEA, (local awards), IOTA, has a dxcluster client, import and export from different format and works with ADIF by default.

General purpose Amateur Radio logging application, written in Gambas2. Focused primarily on VHF and up, it uses custom maps to keep track of Maidenhead Locators worked on all bands, and simple Awards like WAS, USACA, TPEA, etc.

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.
