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!
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.
FERS is a simulator for common radar system designs. It supports both multistatic and monostatic radars,and both pulsed and CW systems. FERS processes an XML script file to produce output in a variety of formats.
A CW beacon implemented in C language on a AVR AtTiny13A microcontroller (1KB flash!).
Include a CW parametric modulator/keyer, an emulated I2C periferal and a device driver in order to handle the Si570 oscillator by Silabs.
You can personalize the transmitted message and the morse speed (in WPM).
In the example the beacon is IQ6MC/B JN63RH @ 144.450MHz.
QRPSim is a contest and general QRP CW QSOs simulator. Currently supports RU-QRP "Russian Hunt" QRP game.
QRPSim is used by novice to increase CW practice in contest-like environment. It useful for training and entertainment, popularizing RU-QRP activities amongst hamradio worldwide.
Contest managers are able to "debug" contest rules by simulating various scenarios with QRPSim.
Ceasar is an open-source multi-frequency tone gereator for UNIX, initially Linux. By default it contains standard DTMF tones together with C5 (bluebox)
tones.
cw(color wrapper) is a non-intrusive ANSI color wrapper for common unix-based commands on GNU/linux. cw is designed to simulate the environment of the commands being executed, so that if a person types 'du', 'df', etc. it will be colored in real-tim

a XHTML+CSS Compliant Form Rendering Class
the idea is to abstract the Form rendering and validation of the from from the workflow.
the class allows you to configure formfields render them with a template using CSS.
Lucene-based search library that leverages on the Spring framework to provide easily configurable searches with little or no intrusion in the application code. You can create indexes from any collection of POJOs and benefit from event-triggered updat
A tool for learning and practicing morse code, for passing amateur (ham) radio license exams.
Converts supplied text to code sounds, or generates random symbols. Speed and farnsworth compression are adjustable. Written in C for Linux or other computers.
